3 Things You Didn't Know About Auxiliary Heat


Heat pumps are typically synonymous with energy efficiency, which is part of why they’re so popular. However, in spite of how common they are, many homeowners aren’t aware of what auxiliary heat is. By understanding this aspect of heat pumps, you can equip yourself to avoid wasted energy in the future.

Auxiliary Heat Is a Support Element

If you’ve ever noticed the auxiliary heat feature on your thermostat but you don’t know what it means, the answer is here. Auxiliary heat is a supplement to the heat pump’s ordinary functions. If the weather outside is too cold to supply heat via the usual transfer from outside to indoors, the auxiliary function kicks in.

Auxiliary Heat Is for Comfort, not Efficiency

If the temperature outside is below freezing, the auxiliary heat turns on to help the pump provide adequate heating. The pump produces supplemental heat, rather than transferring it — this means that while the auxiliary function is active, your pump is using much more energy than usual.

You Might Need to Take Action to Stay Efficient

It’s easy to assume your system is working correctly, but if you notice that the auxiliary heating feature is active even when the weather outside isn’t below freezing, you likely have an issue. The sooner it’s dealt with, the less you’ll spend — the longer you allow the pump to produce auxiliary heat when it isn’t needed, the higher your energy costs will climb.
