Should I Use Separate Heaters for the Pool and Spa?

The answer is NO! You are designing the pool and spa of your dreams in your backyard, but do you really need two separate systems to heat them both?  The fact is that one heater heats both. Simply put, we just send different water sources to the heater thru automatic valves. Here is the explanation. When the spa is not being used, it is simply part of the pool. Water is drawn from the pool and returned to the pool and spa. If the heater is on in this situation, both the pool and spa are heated to the set temperature. When the vales are set to spa, water is drawn from the spa and only returned to the spa. We are now only heating the spa, which is a much smaller body of water and heats very quickly. The pool is basically stagnate during this time.

Here are some ways that your pool can be heated.


This is one of the most popular ways to heat spas and pools. It uses a flame powered by gas to heat water that is then returned to the pool or spa. This is accomplished by using a heat transfer manifold. The largest gas heater available is a 400,000 btu unit.

Heat Pumps

Heat pumps are a good heating option especially in the warmer parts of the country. These machines pull heat from the air and use it to heat the pool. Like air conditioners, heat pumps make use of refrigerant gas and are often a bit more expensive than other types of heating systems. Heat pumps are ran by electricity and not gas. In some cases, they can be reversed and used to cool the water. This is a good option for extreme heat areas like the desert areas.


Most people recognize that solar power comes from the sun. This makes solar an energy efficient and eco-friendly option. With a solar heater, a collector is placed on the roof of a nearby structure, Water is pumped into the collector, heated by the sun and then returned to the pool or the spa.

Professional Company

As mentioned above, most private pools and spas can enjoy a combined heating system. This cuts down on energy as well as on maintenance costs. Heating system can also be programmed to turn on and shut down at specific times. As you can tell, there are a lot of options, so it is best to get a professional opinion.
