A pool heater can make all the difference in your enjoyment of swimming all-year- around, but choosing one can be confusing. This detailed guide tells you all you need to know to choose a heater that will provide the right combination of comfort level, climate, cost and maintenance for you.

A natural or propane gas heater offers rapid heating in most climates, making them a handy option, however, their day to day running costs are higher than their electric or solar counterparts.

Energy Efficiency

When it comes to swimming pool heating, energy efficiency plays a crucial role as there are different types of pool heaters that use different method to produce heat to be used for pool heating, all with different effect on temperature control and utility bills.

An electric heater is a good choice for a smaller environment-friendly pool, but it may accrue then its electricity bills in long run. Propane pool heater, instantaneously heat the required water as per your command much faster compare with electricity heaters which might increase its electricity bills in longer run.

But they’re more expensive – and less efficient – than other options, so you’ll want to calculate an adequate BTU capacity – based on your pool size, water temperature increase, and climate where you live – or those propane heaters could drain your tank in no time flat! For ultimate efficiency and maximum safety, seek out infrared or electronic ignition models of propane heaters tucked into an equipment pad so that they don’t require as much interaction from you. Meaning, look for ones with such a system built right in.


A pool heater must also be sized for the right temperature. You don’t want a small heater that would take too long to reach the proper temperatures for swimming. Too many BTU’s can be a problem also and a large model may be overly expensive and is likely unnecessary.

Like climate, the selection of the good pool heaters should follow a specific pattern. For warm countries solar pool heateers should be a usefull system, in cold region gas and propane heater heaters are the right option .

Frequent use and length of swimming season significantly reduces the life of the pool heater if it is used regularly. Top quality components that use state of the art knowledge, designed for regular use, will reduce stress on the grocery storing appliance. The heater thus can have a longer life. The usage of energy efficient equipment can reduce operation cost as well as satisfy longer seasonal use, allowing for long life of expensive swimming pools, hence reducing ownership costs to the pool owner.

Local Climate

By installing pool heaters, families can extend their swimming season and extend their time and comfort in their backyard pool even during the colder seasons of the year. When a buyer chooses a heater, he should carefully consider both the upfront price and the ongoing operating costs(when choosing the heat he is going to use).

Example: Propane or even natural gas heaters might be a good choice for those on a gas line, but they could turn out to be more expensive to operate than their heat pump counterparts. The best of both worlds could be a dual-fuel system using two completely separate fuels, with an option for the pool owner to switch between them depending upon local prices for either.

Electric resistance heaters may also be a good type of heater, and they are usually cheaper than gas heaters, although they need a large initial investment and they have a very high cost in terms of electricity bills.

Another form of renewable energy for heating pools is the solar system and is particularly advisable for people who are lucky to live in countries with a good amount of summer sunshine.
Choosing one or another type of home heating system can increase and improve the pleasure in the use of your pool and make it an effective and comforting aquatic space as long as it is well planned, maintained and managed throughout the year.


An investment in this pool heater might give you many years of swimming fun, but you must be aware that investor must pay more. The owner of this heater who expects to have convenience and something good, must be aware both in the purchase time and the operating cost every model, before made any decision.

They are usually less expensive to buy and install than electric ones which warm the water at a slower pace, although this cost difference can be annulled by running costs depending on the price of natural or propane gas in a given area.

Like all machines, heaters require periodic maintenance to conserve energy and prolong their useful life. So be sure to read and follow the recommendations in your heater manual to keep it in top shape – that will conserve energy over time and prolong its useful life. Installation of a solar cover is also desirable as it both can minimise operating costs by reducing water evaporation and consequently the amount of chemicals that need to be added.
