Can a Swimming Pool Heat Pump be Installed Indoors?

Although having an outdoor swimming pool is great for the summer season, in the winter, it can be difficult to maintain. A lot of people don’t want to go through the troubles of installing heaters for their outdoor pools, so they choose to build pools inside their homes. Not only are indoor pools easier to maintain, they are also accessible no matter the weather conditions. Since pools can be moved inside, a common question that arises is can swimming pool heat pumps be moved inside as well?

As much as an indoor heat pump would be convenient to use indoors, it’s not the best idea to install it for your indoor pool. Simply put, a swimming pool heat pump extracts heat from its surrounding area, then transfers the heat into the pool to warm up the water. Thus, a heat pump requires a large supply of fresh air for heat to transfer properly. Usually the air leaving the heat pump is 8-12 degrees cooler than the air entering the system.

In most cases, if a heat pump is placed indoors, it would not receive the same amount of fresh air. Instead, the same air would recirculate, causing your indoor air to cool very quickly. Soon, the system would shut down as there wouldn’t be enough heat to withdraw from its surroundings. Despite the difficulties you might run into by installing an indoor swimming pool heat pump, it isn’t an impossible task. If you absolutely cannot place a heat pump outside your home, consult a professional right away to discuss the alternatives.

Different methods are taken for different heating models. If you have a vertical fan model, sometimes ducting kits are helpful in venting out the cold air outside the house and bringing in warmer air from outside. But, if you have a propeller fan model, a duct system no longer works its charm. For horizontal fan models, they can be placed up against the wall where a hole is present to allow the cold air to escape. A benefit of placing the heat pumps indoor is that it can help to dehumidify the air. Nevertheless, indoor heat pumps are very rare. One important thing to remember is that if you really need to have them indoors, you must provide a way to supply 3,500 CFMs of fresh air to your unit.
