Heat pumps are highly efficient when it comes to consuming energy. According to EnergyRating, they are 3 times more energy efficient compared to electric heaters. However, this is not a guaranteed result. For you to enjoy low energy consumption from your heat pump water heater, you must make sure it's installed in the right way. Find out how to do that, plus much more, below.
Install the unit outside
Unlike gas heaters or electric heaters that can operate inside the house, heat pump water heaters must be installed outside. This is because the evaporator needs contact with as much hot air as possible. That means it needs to be outside where the sun-heated air is. Placed indoors, the unit would not provide any heating whatsoever. However, if yours is a split unit, i.e. has a separate evaporator and condenser, you can install the latter outside and the former indoors.
Make sure the unit has maximum sun exposure
Again, remember that the whole point of installing the unit outside is so that it can be in contact with as much heated air as possible. In that regard, simply installing the unit outside is not enough, it must be located in a part of your yard where there's a lot of sun throughout the day. If placed behind a shaded areas, your unit will offer very little cooling or will have to result to the booster power to heat your water.
Place the unit in an open area
In addition to the above requirements, you should have the heat pump placed in an area that is open and free from obstructions. The evaporator has a fan that will be drawing hot air in into its heat exchanger. For maximum efficiency, it needs to draw in as much hot air as possible. That said, do not place the unit next to a water tank or anything that might prevent the hot air from accessing the unit freely.
Keep the unit away from busy areas
The evaporator fan can be noisy if you have a quiet home. It makes as much noise as an air conditioning condenser fan. To ensure you keep getting the peace and quiet you are used to, therefore, have the unit installed far from your busy areas, e.g. living room, dining room or bedrooms. Also keep the unit away from your neighbour's property.
Install the unit close to usage point
Lastly, have the unit placed as close to the hot water source as possible. This has several benefits. First, it will reduce energy loss in the hot water's path from the heat pump to the destination, e.g. the kitchen sink or bathroom showerhead. Two, it will help reduce the amount of electrical power needed to pump the water.
Though it's quite a handful, ensure you observe the above considerations to enjoy your heat pump water heater to the fullest. For more information about heat pumps, contact an installation company.Share
