Even a properly sized heat pump can usually at best only manage to raise the water temperature by around 1-1.5☏ in an hour. Like gas heaters, heat pumps allow you to set an exact temperature for your pool water. The per hour cost to run a heat pump is much less than that of a gas heater. As the pool water passes through the metal tube, it is heated to the desired temperature, at which point the heater shuts off. When the warm air combines with the refrigerant, a chemical reaction occurs which produces a warm gas. This warm air then passes over the heat pump’s “evaporator coil”, which is filled with a refrigerant. Heat pumps work by drawing in warm air from the outside using a built-in fan. The running costs of a gas heater are the highest among the three main pool heater options when looked at on a per hour basis. While the plumbing installation usually doesn’t cost very much, the gas installation can be pricy depending on where your existing gas hookup is located. They also require professional installation. A good gas heater will set you back $2000 or more. Most gas heaters also allow you to set an exact temperature for your pool water. A pool that is 70☏ in the morning can be easily heated to 80☏ or higher by lunchtime! In fact, a properly sized gas heater can easily increase the water temperature in a pool by 3-4☏ per hour. Gas pool heaters heat the water very quickly.This temperature can be adjusted manually using the heater’s built-in controls. This process continues until the pool water reaches a set temperature, at which point the heater will shut itself off. As the pool water flows through the heater, it passes through this coil and is heated. ![]() This burning gas then heats a metal coil. Gas pool heaters work by igniting either natural gas or propane within a “combustion chamber” located inside the heater.

You can then measure the pool at its widest and longest points and make note of those measurements on the sketch. To do this, make a rough sketch of the pool’s shape. ![]() To do this, you will need a rough estimate of the size and volume of the pool. It doesn’t really matter how good the heater is, if it is too small it will not efficiently heat the water in the pool, leading to sky-high energy bills.īefore you buy a new pool heater, you want to make sure that it is large enough to properly heat the water. If you buy a heater that is rated for a 40,000L pool and you have an 80,000L pool you’ve got a problem. When it comes to pool heaters, size really does matter. Properly Sizing Your Heater For Your Poolīefore we get into the different types of pool heater, we need to get something out of the way.
