Propane Education & Research Council

Propane heating systems have an edge when it comes to comfort, efficiency, and emissions

On average, more than half of a household’s annual energy consumption is used for space heating and air conditioning, according to the U.S. Energy Information Administration (EIA).

Seasonal and energy-intensive uses can vary based on geographic location, home size and structure, and energy sources used. Because of higher space-heating demand, homes in the Northeast and Midwest regions consume more energy on average than homes in the South and West regions, for example. Additionally, larger homes and families tend to use more energy overall than smaller households.

There are more options than ever for home heating, and there are several different factors to take into consideration when selecting the best system for your customers. Whether your customers are looking to reduce energy consumption and costs, decrease their carbon footprint, or enjoy more comfortable home heating, propane-powered systems can provide a reliable solution for homeowners across the country. According to data from the Propane Education & Research Council (PERC), more than 7.5 million households rely on propane for primary or secondary home heating.

Here are three key advantages of propane-powered systems to share with your customers next time they ask about home heating solutions.

Homeowners can save more on energy costs with propane

The efficiency of a home heating system can greatly impact its utility costs. For homeowners looking to reduce their energy consumption — and their bills — high-efficiency propane furnaces are a great choice. Propane furnaces offer best-in-class efficiency, with ratings from 90 to 98 percent. Further, ENERGY STAR-qualified propane furnaces are up to 15 percent more efficient than standard propane models and can save up to $75 in energy costs each year, according to data from PERC.

In a comparative analysis of residential heating systems, Newport Partners, LLC examined the performance of seven heating systems in 16 different locations for new and existing homes. Each system was analyzed and compared in terms of its first cost, energy cost, emissions, and simple payback period. The research revealed several cost advantages to selecting a propane furnace, including low annual energy costs. Notably, the annual energy costs of a high-efficiency propane furnace were $1,650, which is 10 percent lower than standard-efficiency ASHPs and 14 percent lower than heating oil furnaces. When used as a backup for an air- or ground-source heat pump system in the place of electric heating coils the efficiency of the systems is also improved and further protects homeowners from rising utility costs when temperatures drop.

Beyond annual energy costs, propane systems offer more competitive upfront costs and payback periods, too. High-efficiency propane furnaces typically cost less to purchase and install than heating oil and ground-source heat pump systems. Additionally, homeowners purchasing a high-efficiency propane furnace for a new home in a cold climate could recoup their initial costs in two years due to low equipment and energy costs. By contrast, it could take a homeowner more than 20 years to recoup the initial cost of a ground source heat pump system through energy savings.

Propane systems provide warmth and comfort

Comfort can often be a deciding factor for homeowners. They want systems that can provide comfortable, consistent heat. Fortunately, propane furnaces are perfect for eliminating cold pockets in a home. These systems heat air to a higher initial temperature, getting to a homeowner’s desired temperature faster and maintaining it more effectively.

Because propane-powered furnaces heat air to 115–125 degrees Fahrenheit, they make the indoor air feel warmer and more consistent than heat from air source heat pumps (ASHPs), which often supply temperatures lower than 100 degrees Fahrenheit and are more affected by cold outdoor temperatures.

Propane systems support environmentally-conscious customers

When making decisions for homeowners heating systems remember those customers are placing more of a priority on reducing their carbon footprint. One way that homeowners can decrease emissions is by having their home’s systems and appliances run on propane instead of electricity.

According to data from PERC, residential propane furnaces can emit up to 50 percent fewer greenhouse gas emissions than electric furnaces and 12 percent fewer greenhouse gas emissions than fuel oil furnaces. Further, propane-powered furnaces produce up to 35 percent fewer nitrogen oxide (NOx) emissions and 82 percent fewer sulfur oxide (SOx) emissions than electric furnaces. And in colder and mixed climates, high-efficiency propane-fueled furnaces produce at least 26 percent fewer carbon dioxide emissions compared to standard-efficiency electric air-source heat pumps. It is extremely important for you to be prepared to educate your customers about these differences and not leave them out in the cold.

Use these tips to keep customers comfortable this winter

Do you know how to ensure your tankless water heater installations perform optimally this winter?

Tankless water heaters — known for their on-demand hot water, low energy use, and compact size — are popular among homeowners. Propane-powered systems offer an additional advantage: they can be installed virtually anywhere.

For customers located in regions that experience snow and frigid temperatures, there are a few considerations for HVAC professionals to keep in mind to ensure their customers’ comfort year-round.

Here are eight tips for specifying, installing, and maintaining tankless systems in cold climates:

1. Size the unit for the cold. As temperatures drop, more time and energy are needed to heat water to the desired level. To ensure customers’ tanks meet demand throughout the year, it’s important to know how they’ll perform in cold weather. For example, in Washington D.C., a unit that can produce 8.5 GPM on a hot summer day will only produce 5 to 6 GPM on a cold winter day.

2. Design for the coldest conditions. Be aware of how low ground temperatures can go and how much water a household will need. Also consider the difference between the set unit temperature and the ground temperature, also known as the Delta T. The bigger the gap, the lower the unit’s flow rate will be.

3. Bring it inside. Many tankless systems have some degree of built-in freeze protection. Check the product specs, and your region’s historical weather patterns, to determine where to install the tank.

4. Vent smart. Proper venting is important. Installations should avoid freezing winds and have sufficiently long vent runs. In cold areas, the minimum vent run recommendation is six feet.

5. Keep vents clear of snow. Before a snowstorm, remind customers to keep a few feet around the vent clear of snow. Some tankless models offer air intake from the outer pipe — if that’s blocked, the unit may turn itself off.

6. Educate customers with recirculators. For customers whose systems have a recirculating loop, remind them to turn off that function when bad weather is on the way. If the vent termination is snowed under, the unit will eventually power off with an error code.

7. Consider condensation. Drain condensate from condensing units into a conditioned space to avoid drain freezes, which will cause the unit to turn off.

8. Be ready with backup power. Many tankless systems need electricity for freeze protection and ignition. A propane standby generator can help ensure that customers’ hot water will continue to flow, even during a power outage.

Increase customer satisfaction with efficient, right-sized propane HVAC systems

Navigating the world of HVAC systems can be daunting for homeowners. It’s a big reason why homeowners tasked with selecting the right HVAC system — either in a new build or as a replacement to an existing system — will often turn to the pros for guidance.

Customers often prioritize quality and price, but there’s another component that’s equally important: size. Selecting and installing a right-sized HVAC system is key to keeping customers comfortable and satisfied year-round.

Installing incorrectly-sized systems can underperform, waste energy, and increase utility costs for homeowners. More specifically, a system that’s too small might not be able to regulate the temperature of the home. An oversized unit, on the other hand, will not work as efficiently, may wear out faster, and could have dehumidification problems.

Most importantly for professionals, is that a well-performing HVAC system can ensure a lifetime customer, so knowing what to recommend when homeowners come calling can have lasting benefits for the business.

It’s all in the details

Determining heating and cooling loads plays an essential role in sizing HVAC systems like A/Cs, heat pumps, and furnaces. Many existing homes have over-sized heating oil or propane furnaces, resulting in heating systems that blast warm air, almost too quickly, when the thermostat calls for heat. Furnaces that are properly sized for the home’s heating load, on the other hand, offer greater comfort — often with a smaller, less expensive unit. HVAC contractors can use a load calculator, which considers the home’s climate region, square footage, insulation grade, sun exposure, and more.

Every home is different, which is why it’s important that heating and cooling systems are designed for the correct load. Did you know that the same house, rotated just 90 degrees, could vary in cooling load by 25 percent or more? These calculations take time and require attention to detail, but will greatly impact a home’s performance, a customer’s satisfaction, and potentially your business’ reputation.

Understand and evaluate load size

A home’s heating and cooling loads drive how much an HVAC system needs to operate to keep a home — and your customers — comfortable year-round. It’s important for HVAC contractors to understand the three different types of loads, the amount of heating or cooling a home needs, and how they relate to a unit’s capacity to provide the best HVAC experience for their customers.

Heating load and capacity can often be easily confused. Heating load refers to the amount of heating or cooling a building needs, while heating capacity is the amount of heating or cooling an HVAC appliance can provide. HVAC professionals base the size of the systems they install on their capacity to satisfy three different kinds of loads — design load, extreme load, and part load.

Design load

The design load includes the layout of a home, its overall energy efficiency, its insulation levels, and its orientation to the sun. Homes with adequate insulation, thermal windows, and little air infiltration have lower design loads. Conditioning loads will differ between single- and two-story homes. If HVAC professionals size a home’s heating and cooling equipment to meet design loads exactly, they may unintentionally specify and install wrong-size equipment.

Extreme load          

The extreme load occurs when experiencing the hottest and coldest temperatures in any given location. This load, unlike the design load, carries little weight when HVAC professionals calculate the appropriate HVAC equipment size. Plus, extreme weather conditions rarely last long enough to significantly impact a home’s overall performance and comfort.

Part load

Partial loads are the most common. During much of the day and throughout the year, heating and cooling loads fall between the design load and the extreme load. Properly-sized equipment may cycle on and off, which can impair comfort, energy efficiency, and humidity control. Fortunately, modern HVAC systems often come with variable-speed and level components that allow the equipment to adapt its running speed or level to current conditions.

Consider the energy source

Once an HVAC professional has determined the correct load and unit capacity, they can select which energy source will power the system. Propane has become an increasingly popular choice among homeowners across the U.S. because it delivers energy savings, reduced emissions, and comfort — all at an affordable cost. In fact, in some regions, high-efficiency furnaces are the most commonly installed system for new homes. In regions where an air-source heat pump is specified, pair it with a propane auxiliary unit instead of electric coils and the unit still provides comfort when outside temperatures fall below 45 degrees Fahrenheit.

High-efficiency propane furnaces offer best-in-class efficiency with ratings from 90 to 98 percent and the versatility to provide space heating to both small floor plans and large custom homes — making them a valuable addition to any project.
