When sizing a pool heater, you should take into consideration the surface area of the pool and average air temperatures. You should also look at the type of pool. An in-ground pool requires more heating than above the ground pools. For heat pumps, they are rated by Btu output and horsepower (hp). The common output sizes are 75,000 Btu, 100,000 Btu and 125,000 Btu.
Costs of installation and running – You should consider the cost of buying and installation a heat pump. Bear in mind that the cost of some in units can cost as much as 4,000 dollars while some can go as low as 400 dollars. You should shop around depending on your budget and requirements.

Solar Pool Heaters -Solar heater- Another option when it comes to swimming pool heater is installing a solar heater. A solar heater is made up of solar collectors, filters, pumps and control valves. Basically, they use the sun’s energy to warm the swimming pool. A solar pool cover works as a regular pool cover for keeping algae and debris out; in addition to that, the solar cover heats the water and helps to reduce evaporation.
Compact design- you will need to buy a pool heater that will not take up lots of space. In most cases electric pool heaters have a small compact design, so they don’,t take lots of space.
Natural gas or Propane heater– A gas pool heater runs on natural gas or propane. There is a combustion chamber that uses gas for heating the copper coil. Water passes through the hot copper coil where it gets heated.
