Boiler or Furnace? Understanding How Each Heats Your Home

Written by Kevin on . Posted in Heating.

When it comes to heating your home, there are a lot of different options. A variety of HVAC equipment tends to get lumped together into the heater category, but the reality is that they use a variety of techniques to generate warmth. These differences can also have a major impact on your utility bills, air quality, and comfort, so it’s worth learning about them. Keep reading to find out how furnaces and boilers work and see which one is right for you.

What Is a Furnace?

A furnace is a heater that works by warming up air and then blowing the warm air throughout your home. There are several ways to fuel a furnace, including gas and electricity. Whatever power the furnace runs on, it generates heat directly and lets the air absorb that heat. The furnace then uses blower fans to spread the air throughout the ducts and into your home. When your furnace is running, it’s constantly circulating air. The fans will pull cool air into the furnace via a return duct and then blow heated air into your home from supply vents. Furnaces are one of the most popular types of heaters available. They work with most standard HVAC designs, so you can find them in all sorts of homes.

What Is a Boiler?

A boiler is a heater that works by distributing water. Boilers use fuel to heat up a tank of water. This hot water is then distributed throughout your home through a series of pipes. Depending on how your boiler is set up, it might use a radiant floor system, radiators, or heated baseboards. Some boilers may also distribute steam instead of liquid water. Wherever the hot water goes in your home, it gradually releases heat into the air and warms up the temperature of your house. Some boilers may also heat water for other purposes, such as showers or washing dishes. Boilers are a less common type of technology. They were more common in historic homes, but they’re gradually becoming popular again in modern times.

Which One Is Right for You?

Whether your heater warms air or water might seem like a minor distinction, but it can greatly change how your home feels. If you’re trying to decide between the two styles of heater, here are some important factors to consider.

Efficiency

If you’re looking for ways to heat your home without using a lot of fuel, a boiler is a better pick. In general, water transfers temperatures more efficiently than air does. This means that it takes more energy to heat air than it does to heat water. The exact amount of money it costs to run a furnace or a boiler will depend on things like your local fuel rates, the efficiency of the model you select, and the type of fuel you use. However, the overall cost to run a boiler can be as low as half the cost to run a furnace.

Comfort and Convenience

While it’s largely a matter of personal preference, many homeowners report that boilers are more comfortable. This is partially due to humidity levels. Furnaces remove moisture from the air as they run, so when you end up with a heater running nonstop in winter, air can become uncomfortably dry. Boilers have more stable levels of humidity, so you don’t get uneven swings in moisture levels. With boilers, you’re less likely to have static shocks, dry skin, and other issues. The ambient heat provided by boilers tends to be even and gentle no matter how long it runs. Another advantage of boilers is that they’re much quieter. You might hear the occasional gurgle of the water tank warming up or refilling. However, you won’t hear the rushing noises of a furnace moving air around. Despite these issues, furnaces may have a slight advantage when it comes to convenience. Many homeowners find that the ducts and vents of furnaces have a lower profile. Unlike a radiator, the components of a furnace do not take up wall space or require you to decorate around them.

Air Quality

When it comes to air quality, both types of heaters have their pros and cons. Overall, boilers tend to be better. Since they aren’t blowing air around, they don’t kick up a lot of dust and allergens. This ensures that things like mold spores aren’t circulating through your home. However, it also means that boilers don’t help with circulation. Furnaces move air throughout your home, so they can filter air and improve ventilation. If your HVAC system is set up with effective filters and ventilation options, it can spread fresh air through your home in a way that a boiler can’t. Ultimately, the average boiler will be better for air quality than the average furnace, but if your home’s HVAC system is set up with air quality in mind, a customized furnace and ventilation system can be better.

Price

Since furnaces are more common, there are a lot more options. This lets you shop around and find much lower prices for equipment. Furnaces are also less complex than boilers and use fewer parts, and this contributes to their lower purchase price. When it comes to installation, furnaces also win out. Most furnace installations are straightforward and use the ductwork system you already have in place for your air conditioner. Meanwhile, boilers can require additional installation for things like radiators or flooring, so adding the entire boiler system to your home is a big project. Don’t forget about the better efficiency of boilers though. Even if the initial cost is higher, you often save money in the long run with a boiler system.

Maintenance and Repairs

Neither furnaces nor boilers require a lot of maintenance beyond an annual service visit. However, furnaces will need you to change their filters every month or two, so there can be a few extra minutes of maintenance. If something goes wrong with your system, furnaces can be preferable. A broken furnace usually just means a cold house, strange noises, or some unpleasant smells. Unfortunately, a broken boiler can be a large hassle. If something goes wrong, a boiler can leak, and the hot water inside it can cause a lot of damage to your home.

Top 10 Benefits of a Professional Heating Safety Inspection

Written by Kevin on . Posted in Heating.

As winter approaches, heaters become essential for keeping your home comfortable. After sitting idle through the spring and summer months, your heater may need care to ensure it’s safe for operation. [company_name] wants you to know the advantages of scheduling a professional heating safety inspection with our HVAC technicians in Sterling, VA. You should schedule a heating safety inspection in late summer or early fall. These inspections ensure your heater will operate safely and effectively.

1. Enhanced Safety

A heating safety inspection allows our HVAC technicians to identify any safety hazards that could lead to a fire or carbon monoxide leaks. They also inspect the heating system for any electrical issues. The US Department of Energy warns of around 25,000 home fires caused by heaters yearly.

Frayed wiring can lead to electrical shock. Damaged fuel lines or cracked heat exchangers can cause carbon monoxide leaks, and clogged air filters can cause heating systems to overheat, leading to fire dangers. Our professional technicians can check your heater and significantly reduce the hazards that could put your family’s health and safety at risk.

2. Energy Efficiency Boost

Well-maintained heating systems operate more efficiently. During a heating safety inspection, HVAC technicians will inspect the furnace and all its components, the ductwork, and the thermostat. They will identify any elements that may be causing energy waste. Addressing these issues can help improve efficiency and reduce your carbon footprint. The US Department of Energy says home and business owners can reduce energy costs by about 30% with annual maintenance and proper thermostat settings.

3. Longer Equipment Lifespan

A new heating system is a significant investment, so it’s important to make it last as long as possible. Your heating system has complex parts that can experience wear and tear with repeated operation. Safety inspections reveal minor problems, like worn belts or loose connections, before they become significant issues. Furnaces can last 15 to 20 years, but one that receives regular maintenance may last even longer.

4. Improved Indoor Air Quality

Your heating system plays an integral role in indoor air quality. Dust, allergens, and contaminants can build up in your heating system and circulate throughout your home. A professional maintenance appointment involves a complete system clean to ensure healthier air. Our technicians can also recommend HEPA filters with your next filter change. Poor indoor air quality can lead to complications, like upper respiratory conditions and increased allergy symptoms. Regular safety inspections and tune-ups can keep your family breathing easier.

5. Better Performance

A well-maintained heating system will perform better and heat your home more evenly. During safety inspections, our HVAC technicians calibrate your heating system for optimal performance. Calibration eliminates hot and cold spots and thermostats become inaccurate over time, leading to heater malfunctions. Our technicians ensure the thermostat’s settings and room temperature match as closely as possible.

6. Valid Warranty

Most new heating systems come with a manufacturer’s warranty, and you can purchase an extended warranty for longer coverage. Your system requires professional maintenance services to keep the warranty in good standing. It’s important to read your warranty’s terms and conditions and follow the maintenance schedule. [company_name] recommends annual maintenance, but your warranty provider may require more frequent inspections.

7. Increased Home Value

Regular professional heating safety inspections can help increase or maintain your home’s value. Should you decide to sell your home, prospective buyers will appreciate a heating system that has received proper maintenance throughout its lifespan. Attention to maintenance makes your home a more attractive purchase, potentially increasing your profits in the sale. It’s important to keep extensive records on any heating system maintenance and repair.

8. Reduced Repair Costs

During a heating safety inspection, our HVAC technicians check for damaged components that may need replacing. They also tighten connections and lubricate parts, which can help prevent premature failure. Investing in routine maintenance can help avoid costly repairs or the need for a premature heating system replacement. Catching minor issues before they become big problems keeps your heating system operating at its prime.

9. Noise Reduction

With continued heating system operation, what starts as a quiet hum can turn much louder. Heating systems can begin to rattle, buzz, or make banging sounds. Sometimes, these sounds result from wear and tear but can also occur because of friction. Annual safety inspections and tune-ups can help prevent increased sounds or reduce them if they are present. Well-maintained heating systems operate more smoothly and quietly, making your home more relaxing in the winter.

10. Peace of Mind

Heating system safety inspections give great peace of mind. A technician will check every component, including the electrical system, blower motor, and heat exchanger. The component and hazard checks will assure your system’s reliability. Safety inspections reduce the risks of dealing with heating system emergencies that can cause stress. Scheduling a safety inspection means enjoying the winter without feeling like your heating system is a ticking time bomb.

Components of a Heating System Safety Inspection

A safety inspection is a highly detailed process that involves many steps. Although the steps differ slightly between electric and fuel-driven heating systems, many are the same.

Comprehensive Safety Checks

Our HVAC technicians use multiple tools to perform comprehensive safety checks on heating systems. Combustion analyzers measure the level of gases in your heating system’s exhaust. They ensure the fuel burns safely and efficiently by analyzing the combustion ratios and ensuring no dangerous gas leaks.

Carbon Monoxide Detection

Our technicians also use portable carbon monoxide detectors to check levels around the heating system. These detectors can help technicians find the source of any leaks that can lead to dangerous carbon monoxide buildups in your home. Our team will also ensure proper ventilation as a source of prevention.

Gas Pressure Testing

Digital manometers measure the gas pressure in fuel-driven heating systems. Manometers ensure your heating system operates with safe and efficient gas pressure. If the pressure is too high, the heating system can overheat and become unsafe. Low pressure can cause incomplete combustion, impacting heating system function and causing potential damage.

Electrical Continuity Checks

Our HVAC technicians use multimeters to check electrical connections and ensure no continuity issues. Without electrical continuity, the system can’t generate heat properly. Loose or damaged electrical connections can lead to system failure. These components may become damaged by wear and tear or rodents. Regular checks can help prevent minor electrical system wear from becoming a serious and dangerous problem.

Overheating Detection

Infrared thermometers allow technicians to check the heating system’s operating temperature to prevent overheating. Overheating can occur for many reasons, including clogged filters, faulty heating elements, restricted airflow, and low refrigerant. If the temperature readings are not at the proper level, our technicians will work to diagnose the cause.

Cleaning

In addition to checking the heating system components, [company_name] also uses special vacuums and coil cleaning tools to clean the coils and burners, improving system performance and safety.

Are Electric Furnaces Better Than Gas?

Are Electric Furnaces Better Than Gas?

Written by Kevin on . Posted in Heating.

Whether you’re looking for a heating system for your newly constructed home or you’re ready to replace your existing one, a furnace is a great option. This type of heating system can run on various fuels, including propane, natural gas, heating oil, and even electricity. Two of the most popularly used are electric and gas furnaces. But which one is best for your needs?

How Do They Heat?

There is a stark difference in how a gas furnace works compared to an electric furnace. With a gas furnace, combustion is used to create heat. When your thermostat tells your furnace to turn on, your gas furnace will pipe natural gas to its burner.

The ignitor in the burner lights this gas on fire via combustion. Then, the heated gas enters a narrow chamber known as the furnace’s heat exchanger. Cold air from your home is circulated across the heat exchanger, where it absorbs the heat created. Then, the heated air is forced back to the rooms of your home through your ducting. This process continues until your thermostat senses that the ambient room temperature is at your desired temperature setting.

An electric furnace works much differently. Instead of using an ignitor to burn fuel, it uses heating elements. These elements are powered by electricity and emit heat. As air gets pulled into the furnace, it crosses the heat exchanger, where the heating elements are found. The air will absorb the heat and then get forced back into the various rooms of your home to increase their temperature.

Energy Efficiency

When it comes to energy efficiency levels for heating systems, they are based on AFUE ratings. This stands for annual fuel utilization efficiency, and the higher the number, the more energy efficient the unit is. When it comes to natural gas furnaces, they have a typical AFUE rating of 78% to 84%. This means that for every input of gas, only between 78% and 84% of its energy is converted into heat. That leaves 16% to 22% of that energy being lost during the heating process.

Electric furnaces have a typical efficiency rating of 100%. This means that no energy input is lost when creating heat for your home. There’s no denying the fact that an electric furnace well outperforms natural gas-powered furnaces when it comes to the topic of energy efficiency.

Operational Costs

Apart from comparing their upfront and installation costs, it’s only fair to compare their operational costs. Pretty much everywhere in the country, natural gas is going to be cheaper than electricity. Therefore, electric furnaces are going to cost more per unit to run than natural gas-powered furnaces. It’s also important to note that natural gas isn’t readily available everywhere, especially in rural communities. However, electricity is widely available throughout the nation, even in those rural communities.

Safety

No matter what type of furnace you purchase, safety is always going to be at the top of your mind. When it comes to furnaces, the burning of actual fuel will create unwanted harmful exhaust fumes. For example, burning natural gas will emit carbon monoxide and other pollutant fumes into the air. Your furnace will be constructed to naturally vent these fumes to the outdoors to keep your home safe.

However, there’s always the possibility of harmful fumes leaking out of a cracked heat exchanger or a venting system that has developed a leak. You’ll need to have carbon monoxide detectors in your home to alert you of any potential hazardous fumes that are backing up into your home.

When it comes to an electric-powered furnace, there’s no creating of harmful exhaust fumes. There’s no need for venting or having carbon monoxide detectors. This can go a long way in creating peace of mind for you and your family when it comes to the safe operation of your new furnace.

Longevity

As with any investment, you want to see which option is going to give you the most bang for your buck. When it comes to a natural gas furnace, you can expect it to last anywhere between 15 and 20 years. On the other hand, an electric furnace is well-known to last 20 years or more. This is simply due to the fact that the internal components of an electric furnace don’t have to deal with the byproducts of the combustion process that natural gas furnaces do.

Maintenance Requirements

Regardless of whether you invest in a gas or electric furnace, you’ll need to get yearly maintenance by a licensed HVAC professional. With an electric furnace, the maintenance process tends to be much quicker than with a gas furnace. Since gas furnaces burn fuel, they have more internal components, like a burner. All of these components need to be cleaned of byproduct debris. Additionally, the exhaust venting system will need checked for safety. This takes longer and is a more invasive maintenance process.

Noise

Another area of notable comparison between natural gas and electric furnaces is their operational noises. It’s important to note that each system will rely on ducting and the indoor air handler to circulate air through that ducting, which will produce a faint whooshing noise. However, with an electric furnace, there will be no other noise. With a natural gas-powered furnace, you’ll experience a loud rushing noise when your furnace first starts up. This is the sound of your burner igniting and gas being lit.

Heat Pumps vs. Furnaces: Key Differences

Written by Kevin on . Posted in Heating.

There are several ways to heat your home. What are the differences between a heat pump and a furnace? Which one is best for your situation? In this short guide, we will explore the main differences between the two heating systems and their pros and cons. Some things we will look at include how they work, energy efficiency, size and space requirements, and maintenance needs.

How a Furnace Works

There are several types of furnaces: gas, electric, and oil. Regardless of which fuel source a furnace has, it uses a burner and heat exchanger to heat your residence. Once the burner is hot, the hot air transfers to the heat exchanger. A big fan is then used to blow the hot air into your ducts, which distribute it around your home’s interior. Furnaces work well in colder climates since they create their own heat.

How a Heat Pump Works

A heat pump uses air from outside or underground and moves it into your home to heat it. In the summertime it essentially does the same thing in reverse. It’s both a heating and cooling system. In the colder months, it collects heat from outdoors and uses refrigerant to transfer it inside. The refrigerant heats the coil or heat exchanger, and then your ductwork disperses the heat throughout your house. In the warmer months, it does the opposite. It removes the hot air from inside, leaving cooler air behind.

Differences Between Heat Pumps and Furnaces

Even though these two systems work similarly and for the same purpose, there are some key differences between them.

Efficiency

Both systems can be energy-efficient, but depending on local weather conditions, one may be better than the other. Furnaces tend to be more efficient in colder and harsher climates, although heat pumps can still work well in the Virginia winter. The fuel that is most efficient for a furnace is usually either natural gas or electricity. Heat pumps use only a small amount of electricity, so they’re super energy-efficient until the temperature falls below freezing. Once the temperature drops this low, a heat pump must work harder to get heat into your home. This makes a furnace more efficient for freezing temperatures.

We can also install a two-stage furnace, which helps make your furnace more efficient. These more modern furnaces have two levels of heat output, one for milder temperatures and one for more extreme cold temperatures. Most of the time you only require the lower setting, which runs on less energy and is more efficient. It operates at a lower speed, which helps the filters collect more contaminants, making your air cleaner. It also runs quieter than a standard furnace, and there aren’t any sudden blasts of air or noises when it turns on. Overall, it helps regulate temperatures inside your home better than a standard furnace.

Durability

Generally, furnaces can last longer than heat pumps when properly maintained. On average, furnaces last for 20 years while heat pumps last for around 15 years. Heat pumps are more complicated systems, making it more likely something could go wrong. Regardless of which system you have, it is good to schedule routine maintenance to make sure it lasts for as long as possible.

Maintenance

One of the most crucial ways to ensure that everything is functioning properly and prolong the life of your system is through routine maintenance for your heat pump or furnace. During maintenance, our professional HVAC technicians will come and do a thorough inspection of your system. We can diagnose and fix any problem you may have, whether you have a furnace or heat pump.

Furnaces usually have less to maintain. Most of the time a furnace only requires changing filters, vacuuming the inside, and cleaning the flame sensor. Our technicians also go beyond these basics and make sure every component in your furnace is working correctly and do calibration checks for the control system as well.

Heat pumps are more complex, so they require more maintenance. It is good to keep the outside unit clear of ice and snow as well as leaves and other debris. You should change air filters once a month, and clean coils when they are dirty.

Size and Space Requirements

Usually, you install furnaces inside, typically in your basement or some out-of-the-way location. They do, however, take up more inside space, at least 30 inches on all sides. You install heat pumps on the outside of your home, although if you have an air-to-air heat pump you will also need to install an inside fan coil. They only take up around 24 inches of clearance on all sides.

Cost

The overall cost depends on the type of furnace or heat pump you purchase. An air-to-air heat pump is generally less expensive to install compared to any other system, however, they don’t do as well in below-freezing temperatures. Geothermal heat pumps that collect heat from underground sources are more expensive to install, but they can function better in colder temperatures.

Gas furnaces cost more to install since they require gas lines and ventilation systems, but they don’t cost as much as heat pumps. Gas is usually less expensive than electricity, so the costs of running it may be lower.
