Winter Heat Pump Tips
Here are a few tips to get the most out of your heat pumps this winter:
Use your heat pumps all winter.
High-performance heat pumps are the most efficient heating system, even on the coldest winter day. If you have both heat pumps and a boiler or furnace, your heat pumps are the more energy-efficient choice.
Set it and forget it.
Heat pumps operate most efficiently when holding a steady temperature. Turning heat pumps down when you’re away or asleep may actually use more energy than leaving them on. The reason is that they have to work harder to come back to the desired temperature than they do to maintain it. It’s best to set them at a comfortable temperature and forget it. Adjusting the temperature for short periods of time, such as overnight, will not save money with heat pumps.
Set temperature for comfort.
Many heat pump indoor units are mounted high on the wall. Because heat rises and heat pumps measure temperature at the indoor units, you may find you need to set your heat pump at a higher temperature than with a traditional wall thermostat setting to feel comfortable. This may be different for heat pumps with floor units or wall-mounted thermostats.
Avoid “Auto” mode.
In “Auto” mode, heat pumps maintain a constant temperature by alternating between the “Cool” and “Heat” modes. To avoid accidentally air conditioning on a mid-winter sunny day or perhaps when a wood stove is running, use “Heat” mode, not “Auto.” Likewise, to avoid accidentally heating on a cool summer night, use “Cool,” “Dry,” or “Fan” mode, not “Auto.”
