Customers often come to us and ask how they can make their swimming pool more…
The main advantage of purchasing a heat pump is that it allows you to extend your pool season. You can even enjoy the pool in the winter months. This is especially helpful if you live in an area where temperatures drop dramatically during the winter. You may ask “How cold is too cold to use my heat pump?”
In this article, we will answer that question, and provide some information to help you get the most out of your unit.
A “heat-only” pump designed to only heat the water and not cool it can work effectively down to the lower 40s. However, the ambient temperature greatly affects the ability of air-source heat pumps to produce heat. The colder the air, the less heat your heat pump will be able to produce. You can extend the lower temperature limit for your heat-only pump by winterizing it when the temperatures drop.
Some units, like the AquaCal ICEBREAKER®, are “reversible” and provide heating or cooling. Reversible units can also operate when the outside temperature is down to the mid to lower 20s. However, that does not necessary mean it can heat the pool to 80° on a 20° day. As a rule of thumb, the highest water temperature rise you can get from an air-source heat pump under ideal conditions is 30°. For example, if the outside temperature is in the 40s, you can expect the pool to warm up only to the 70s.
Commercial Heat Pumps
Not many heat pumps can handle the demand of heating commercial swimming pools. Although can install several residential heat pumps to create enough BTUs to heat any size pool it may be inefficient. There is, however, a reversible unit on the market that could create almost a half a million BTUs with just one heat pump: The Great Big Bopper (GBB). To read more about the GBB, please click here.
There are also geothermal heat pumps that are produced for commercial applications. For more information on geothermal heat pumps pool heaters, click here.
These options will help you enjoy your swimming pool even in the colder months. Just bear in mind the limitations of your unit as indicated by the manufacturer. This is the most important step in helping it run efficiently and without being damaged. Next time you ask yourself “How cold is too cold to use my heat pump?” remember there are options.
Regardless of the when Old Man Winter decides to visit, you can extend your swim season beyond…well…swim season!
