What should I consider when selecting a new pool heater?

Pool heaters are a wonderful convenience in the cold New Hampshire climate. We typically only have a couple of months of a real summer season. By the time the pool warms up naturally from the weather, the time we have to enjoy it is reduced. A pool heat pump can be a great investment so that you can use your pool for a longer amount of days during the season. Or of course, if you wanted to use your pool year-round, a heat pump is a must even for indoor pools. There are several great options for pool heaters and you should consider the usage of your pool before you decide. 

Fuel Type

What is your existing fuel type or what fuel sources do you have in your home to power the pool heater.Is it propane or natural gas? There are advantages and disadvantages to each heater, whether heat pump or gas unit, but the type of fuel helps narrow down the options.

Usage and Recovery

This is possibly the most important thing to consider. Are you looking to maintain a constant warm temperature or are you looking for an occasional pool warm-up? This will indicate the type of pool heaters you should look at. A heat pump is built for a lower recovery than a gas unit. Heat pumps are generally far more efficient but gas gets you warmed up quickly. This is important to decide which you are more likely to benefit from.

What Pentair pool heater is right for me?

The selection of the right Pentair pool heater will be based on the factors already discussed. Additionally, the size of your pool and the area in which you live will impact the model and size of the pool heater needed. We recommend having Custom Climates come out and gather all the data needed for a proper design for your pool. Custom Climates expertly designs and walks you through the process.
