What Is a Hybrid Water Heater?

To comprehend the principles of hybrid pump water heater, envision a refrigerator functioning in reverse. A refrigerator eliminates heat from its confined housing and ejects heat into the air, while a hybrid water heater seizes heat from ambient air and heats-up the water in the tank.

what is a hybrid water heaterTop hybrid water heaters have an integrated evaporator fan and compressor that draws ambient heat from the air to heat the cool liquid refrigerant. This process triggers the compression of liquid to gas, to increase the gaseous refrigerants temperature.

This hot gaseous refrigerant transports’ heat via transfer coils towards to the bottom of the storage tank, whilst distributing heat to the water inside. This causes a transformation phase to occur by changing the refrigerant from the hot gas to warm liquid. The warm liquid refrigerant then travels through expansion valves to cool, and the system repeats itself.

Hybrid water heaters are arguably more economical than mainstream electric water heaters; however, the start-up cost is higher, and you may experience problems causing further difficulties during their use. Considering that a good hybrid electric heater has a fan, care should be taken during installation to prevent blockages within intake or outflow regions. Additionally, a hybrid water heater has water filters that need to be washed regularly, otherwise, the unit may cease to work, if at all.


  • Absorbs ambient heat from surrounding air using an integrated evaporator fan and compressor to heat-up and transform the cool liquid refrigerant into gas
  • Hot gaseous refrigerant transports heat via transfer coils to the bottom of the storage tank in order to transfer heat in liquid form through the expansion valves to heat the water inside
  • Heat pump water heaters are more economical than mainstream electric water heaters
  • Start-up costs are higher than electric resistance heaters
  • The water filter and integrated fan should be taken care of and washed regularly to maintain optimum operations

Pros and Cons of Hybrid/Heat Pump Water Heaters

So, what are the pros and cons of purchasing a hybrid or/heat pump water heater compared to traditional water heaters? With any new application technology, most hybrid water heaters reduce the cost of hot production as they are 2.5 times more energy efficient, in conjunction with lowering carbon emissions and providing greater per-annum savings in fair weather climates.

Therefore, the following key points outline the benefits and drawbacks of hybrid water heaters. Most people have installed standard water heaters in our homes. For these reasons, these reviews provide a multifaceted overview as to whether these water heaters are right for your home.


  • Cools the surrounding mechanical space in the summer, causing the area next to the water heater to feel more comfortable
  • Uses excess waste heat from the central furnace throughout the winter months
  • Can save $330 per annum for a family of four, contingent on water usage and electricity rates
  • Hybrid water heaters are arguably more economical than electric resistance water heaters and pay for themselves over 2-3 years or so.
  • Consumers save 60% on expenditures compared to regular electric water heaters, whereas only 10%–20% will be saved in winter months.
  • Rather than burning hydrocarbons, or use brute force with electrical resistance heaters, a hybrid water heater utilizes technology identical to refrigerators, by drawing heat from ambient air and deposited into your hot water.


  • The cost to run a heat pump water heater is twofold compared to electric resistance water heaters
  • The compressor makes a noticeable noise. Insulating the mechanical space can diminish the sound, but decreases hot air volume for the hybrid water heater to exploit
  • The heating system works arduously in winter months since it produces more cold air whilst functioning
  • Additional space is required for air flow (1,000 cubic feet) and for the condensation drain or pump
  • Slow recovery time can be an issue when demand for hot water is high
  • A hybrid water heater saves significant energy per annum, but the net performance drops in during winter months because a hybrid water heater cools the surrounding mechanical space. During the summer the air conditioning doubles; however, during exceptionally cold winters, the temperature can drop by 47°F, which is not helpful.
  • Hybrid water heaters have a fairly slow recovery rates
  • The key issue is that hybrid water heaters have very noisy built-in fans and compressors, so basements need to have decent acoustic isolation in the surrounding mechanical water heater space. For example, wall insulation, plus retrofit ceiling and flooring.

Hybrid Water Heater Installation Requirements 

Are you swapping the old water heater and replacing it with a good hybrid water heater? Smart move. Preceding installation, you should check the following guidelines to ensure that the hybrid water heater works in your home.

  • A hybrid water heater should ideally be installed in large dry storage spaces with high ceilings, comprising of garages, attics, or closets. Prior to installation, the mechanical space should have louvered doors to pull air from different regions. It’s also desirable to have a condensate drain; however, the drain line can either be run outside or a pump can be added.
  • Moreover, the hybrid water heater should be positioned within a large secluded area protected from freezing temperatures. Wherever the heater is placed, you need to consider that any rooms next to the hybrid water heater will be cooler after the removal of surrounding hot air.
  • Shut off the water and power supply, drain off the left-over water, and disconnect electronic connections, and label all the wires. Afterwards, place the drain pan (two inches larger than the base of the water heater), and set the new water heater on top of the drain pan beneath the water supply lines, before proceeding to the next step.
  • To insert your new-fangled hybrid water heater, solder the fittings onto the water pipes within the new system. Sound advice is to utilize thread sealant for both the hot and cold unions, especially if you’re recycling old fittings and water pipes. Afterwards, attach your water heater to the shut-off valves on both the hot and cold water supply lines.
  • With the condensate drain, ensure the drain line upholds a downward slope for appropriate drainage via gravity to avoid clogging. Also, be careful to direct the drain lines away from live electrical components.
  • In order to fill the tank, firstly ensure the drain valve is closed, and then open the shut-off valves connected to the cold-water supply line. Gradually open hot water faucets so air is expelled through the water heater and piping. Now reconnect the existing electrical cables as labeled earlier by following the manufacturer’s directions, and turn the power back on using the codes on the control panel.
  • Finally, adjust the water and high temperature settings as desired through the control panel, where the average water heater is set to 135 degrees Fahrenheit; however, choosing lower temperatures ensures you can save money.


  1. Drain and detach the outmoded water heater.
  2. Fix a panel onto the basement wall, then attach the hybrid water heater to the panel.
  3. Connect the water heater exhaust vent to the outdated vent pipe.
  4. Fasten a fresh-air line onto the top of the water heater.
  5. Attach the hot and cold water system to the water-supply line, and attach a contemporary gas line onto the side of the heater.
  6. Connect a temperature and pressure release valve with clearance pipe.
  7. Attach a condensate drain line with limestone neutralizer to siphon underneath the heater.
  8. For bigger households, install a recirculation pump to guarantee hot water is obtainable at far away plumbing fixtures.
  9. Turn off the heater and fine-tune the water temperature to approximately 120-degrees F.

The calculation of the energy factor is founded on unbiased regulating standards cultivated by the Department of Energy. This is fantastic as there is no leeway to confuse customers with unclear data. and delivers a dependable tool to compare different water heater designs.

First Hour Rating

The DoE is explicit data concerning hybrid water heaters. It expresses how many gallons of hot water is produced in the water heater over one hour. This information is also dependent on the tank size, the power of the electric resistance heater, and heat pump.

This is referred to as the First Hour rating, which is measured at the inlet of water temperature set at 40°F when the unit’s thermostat is set to 135°F. At this point, water is pulled at 3 gallons per minute until the temperature falls below 135°F. The first hour rating is the total volume of hot water used by the new unit in the first hour.

First hour rating is extremely useful to estimate if the water heater is able to maintain your households’ peak hour hot water requirements. Whilst shopping for a new hybrid water heater, ensure you check the DoE page for Sizing a New Water Heater.

Bottom Line

Choosing the best hybrid water heater is a confounding task. Selections are based on predilections of whether your household has a large mechanical space, the number of operating modes each unit contains, the type and tank size, the number of people living at your home, and the start-up costs compared to traditional electric resistance heaters.

Conditional on the manufacturer’s blueprint, the choice of hybrid water heaters may depend on the energy factor, and the First Hour Rating to compare different designs, and to judge if the new appliance is able to maintain your households’ peak hour hot water needs.

The choice of the top rated hybrid water heaters is also swayed by the recovery rate based on the number of people in the household having showers, and the fuel type (i.e. propane or natural gas). Such features affect the choice of hybrid water heaters because additional installation costs increase start-up costs.

To wrap-up, after reading these hybrid water heater reviews, users can choose the best option that aligns with their personal needs.
