5 Things to Consider Before Buying a Heat Pump - PR Newswire

MISSION, Kan., Sept. 24, /PRNewswire/ -- (Family Features) If you're like many homeowners who are considering ways to achieve greater energy efficiency, cut costs long term and reduce use of fossil fuels, replacing your gas furnace with an electric-powered heat pump may be part of the solution.

Like an air conditioner, a heat pump is installed outside the home and can cool it, but heat pumps are also capable of providing heat. In fact, many homeowners can't tell the difference between a traditional heat pump and an air conditioner because they look alike and have similar hook-ups. However, in cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and similarly, in warmer months, it pulls heat out of indoor air to cool your home.

When considering purchasing a heat pump for your home, it's important to evaluate several factors to ensure you make an informed decision. Here are five key things to consider from the experts at Carrier, a leader in high-technology heating, air-conditioning and refrigeration solutions:

1. Energy Efficiency
Heat pumps are rated by their Heating Seasonal Factor, which is a measure of a heat pump's overall energy efficiency during the heating season; their Seasonal Energy Efficiency Ratio (SEER2); and their Energy Efficiency Ratio. These ratings are like miles per gallon for a car: the higher the rating, the more energy-efficient the system is, which can lead to lower utility bills. For example, standard SEER2 ratings today are around 14.3 (and some older units are as low as 8), but units with a SEER2 rating above 16 have lower energy costs, which translates into higher energy savings.

2. Climate Suitability
Heat pumps are most efficient in areas with moderate temperate ranges. If you live in an area with extreme cold, you may need a heat pump designed for low temperatures such as Carrier's Infinity Heat Pump with Greenspeed Intelligence, which operates at temperatures as low as minus 15 degrees. Or you can combine a heat pump with a gas furnace in colder climates for energy-efficient heating on all but the coldest days.

3. Cost and Incentives
While heat pumps can be more expensive initially, their efficiency can lead to long-term savings. Research available incentives, rebates and tax credits that can help offset some of the upfront cost. Many governments, manufacturers and utility companies also offer financial incentives for installing energy-efficient systems. For example, the Inflation Reduction Act of provides several tax credits, up to $2,000 for qualified heat pumps, and is available through .

4. Size and Capacity
It's essential to ensure the heat pump is the appropriate size for your home. An undersized unit may run virtually nonstop to try and maintain a comfortable temperature inside your home while an oversized unit will cycle on and off frequently, reducing efficiency and lifespan. A professional Carrier dealer can help you determine the correct size based on your home's heating and cooling needs.

5. Installation and Maintenance
Professional and proper installation are crucial for optimal performance. Choose a reputable, experienced HVAC contractor to install your heat pump. The average lifespan of a well-maintained heat pump is 15 years. However, with varying conditions and homeowner habits, it could live well beyond that.

Understand the heat pump's maintenance needs, including regular filter changes, coil cleaning and annual inspections to ensure longevity and efficiency. Without regular cleaning and maintenance, dirty coils can cause your system to work harder to keep up with demand, decreasing efficiency and increasing stress on the fans, motors and system components. Dirty, clogged air filters can restrict airflow, resulting in reduced comfort, higher utility bills and, in extreme cases, a total shutdown of the system.

By carefully considering these factors, you can choose a heat pump that best meets your home's needs and provides efficient, reliable heating and cooling. Learn more at Carrier.com.

10 things you should know before buying a heat pump water heater

More Australians are installing heat pump water heaters as an energy-efficient alternative to traditional electric and gas hot water systems. They use ambient heat from the surrounding air to heat water, helping homeowners save on their hot water energy consumption and reduce their carbon emissions.

However, there are some common questions to consider before installing a heat pump. In this article, we’ll look at the 10 most frequently asked questions about heat pump water heaters to help you make an informed decision.

1. How does a heat pump water heater work?

A heat pump extracts heat from the surrounding air and transfers it to your water in a few key steps:

  • Heat Absorption: Surrounding air is drawn into the system which then passes through an evaporator A liquid refrigerant absorbs the ambient heat from the air and turns to vapour.
  • Compression: A heat pump contains a compressor which turns the vapour to a hot gas.
  • Heat Exchange: The high temperature gas passes through a microchannel heat exchanger which wraps around the tank and heats the water.
  • Cycle Repeat: After heat is transferred to the water in the tank, the refrigerant returns to a liquid state where the cycle repeats.

2. What is the difference between heat pump and solar water heaters?

Solar and heat pump water heaters are both renewable options, but have some key differences. Solar hot water heaters use the sun’s direct and indirect solar radiation to heat water through collectors mounted on the roof, whereas a heat pump uses the ambient heat in the surrounding air.

A heat pump is an excellent alternative for homes where solar may not be suitable due to reasons such as too much shade, limited roof space and your home’s orientation.

3. Are heat pumps eligible for Government Incentives?

Heat pumps are eligible for Small-scale Technology Certificates (STCs), an Australian Federal Government program to reduce the upfront cost. Some states also have their own incentives which can be used in addition to STCs to help further reduce the initial cost.

How much you can save with these incentives depends on your location, the capacity and efficiency of your new heat pump water heater, and the system you are replacing.

4. I have an electric water heater. Can I replace it with a heat pump?

Not only does a heat pump have a similar storage tank to an electric hot water system, but it often uses similar electrical and plumbing connections, making for an easy replacement provided your existing system is installed outdoors.1

A heat pump needs sufficient space outdoors for air circulation, so be sure to speak with your plumber or local Rheem solar specialist to evaluate your setup.

5. Can a heat pump work in cold weather?

Heat pumps work in cold weather to ensure you have hot water when you need it most. Here are some details on the temperatures Rheem heat pump water heaters can operate in:

  • Rheem AmbiPower MDc-180 Heat Pump: -7°C to +43°C.
  • Rheem AmbiPower 280e Heat Pump: -6°C to +43°C.
  • Rheem Ambiheat HDc-270 Heat Pump: -5°C to +43°C.
  • Rheem MPi-325 Series II Heat Pump: 5°C to +43°C.2

If temperatures fall below the minimum level or the heat pump stops heating for any reason, there is a backup element to ensure you always have a supply of hot water. The Rheem MPi- 325 Series II Heat Pump has a 3.6kW backup element, and the Rheem AmbiPower and Ambiheat options have a 2.4kW element.

6. How much could I save on my energy use with a heat pump?

How much energy you can save depends on different factors including the climate where you live, type of water heater being replaced, hot water consumption and fuel tariff. As a guide, here is how much you could save when replacing a similar-sized electric water heater with each Rheem heat pump.3

  • Up to 65% with the Rheem MPi-325 Series II Heat Pump (325 litre capacity).
  • Up to 70% with the Rheem AmbiPower® MDc-180 Heat Pump (178 litre capacity).
  • Up to 73% with the Rheem Ambiheat® HDc-270 Heat Pump (270 litre capacity).
  • Up to 73% with the Rheem AmbiPower® 280e Heat Pump (280 litre capacity).

7. Is installing a heat pump good for the environment?

Installing a heat pump has environmental benefits. Because they use a renewable source of energy, they consume less energy and emit fewer carbon emissions.

Also, newer heat pump systems are manufactured using lower Global Warming Potential (GWP) refrigerants. GWP is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time, usually 100 years. When released in the atmosphere, they act like a blanket insulating the earth and have a significant impact on global warming. Hence, the lower the GWP a heat pump has, the more environmentally friendly it is.

Rheem’s AmbiPower 280e Heat Pump uses the Ultra Low GWP refrigerant R290. The Rheem AmbiPower MDc-180 and Rheem Ambiheat HDc-270 Heat Pumps use low GWP refrigerant 513a.

8. Are heat pumps noisy?

Heat pumps make some noise due to the operation of the fan. Newer systems are designed to make less noise, comparable to that of an air conditioner or refrigerator.

9. Does a heat pump require maintenance?

It is recommended you have an annual inspection of your heat pump water heater by a plumber. This includes checking and cleaning air filters, inspecting the refrigerant level and removing any sediment buildup in the tank.

10. What do I need to know about the installation process?

A licensed plumber will:

  • Understand your installation requirements and provide advice on the best solution for your home.
  • Recommend the size and type of heat pump to suit your household hot water requirements.
  • Install a heat pump from a reputable brand like Rheem to avoid coming back to fix an inferior product or installation.
  • Talk you through the costs and options, and ultimately complete an installation that meets Plumbing and Building codes
