Heat pump water heaters are among the most energy-efficient water heating systems today. Unlike gas and electric units that use fuel for heating, heat pumps use heat from the ambient air to heat water. As a result, they have low operational costs, which can generate significant annual savings. However, the reliability of a heat pump water heater depends on where you install it. Choosing the wrong installation location can hurt the unit's performance. Below are three key reasons why location matters when installing a heat pump water heater.
Water Heater Efficiency
Heat pump water heaters rely on the ambient air to draw heat for water heating. Therefore, the air around the installation location can determine its efficiency. Below are two aspects of the ambient air that matter when installing the unit.
The volume of surrounding air
The volume of the surrounding air in the installation location determines how much heat the heat pump can absorb. If there is less air, the unit won't absorb much heat. Therefore, it will be forced to switch to booster mode and use electrical energy for heating. Experts recommend at least 1,000 cubic feet of air around the heat pump for efficient heating. Before installing the unit in a small closet or pantry, ensure there is adequate air in the room.
Heat pump water heaters work best in warm, heated rooms with stable temperatures. If the temperature is too low, there won't be enough heat for water heating. The system will switch to electric water heating. If the temperatures keep fluctuating, the unit won't work efficiently. Therefore, an outdoor installation isn't ideal for your heat pump. Also, don't place the water heater in uninsulated spaces, such as the garage or basement.
Heat pump water heaters consume less energy because they only need electrical power to run the electrical components. Therefore, when the unit is installed in a warm space with adequate ambient air, it consumes less power. However, when the air isn't warm enough, the unit switches to booster mode and uses electrical energy for water heating. If your water heater uses the electric booster frequently, it will consume a lot of energy and increase your electric bill.
Access to the Unit for Maintenance and Repairs
Heat pump water heaters require regular maintenance to work efficiently. You must flush the system annually, check electrical fittings, inspect the valves, and clean the filter. Install the unit where you can easily access it for routine maintenance and repairs. Failure to do so can complicate these tasks and increase the cost of professional maintenance.
