We aim to provide all you need to know about pool heaters in general and also look at the most popular models.
Do you need a pool heater?
You may be concerned about the cost or perhaps that heating a swimming pool might be environmentally unfriendly. These are valid points but if you have already made a significant investment in a pool you will get a lot more use out of it with a pool heater and swimming is a very good form of exercise (see Why install a Pool Heater).
What type should you go for?
Before looking at pool heater reviews of individual models you need to decide on the type of heater you want. You can choose between:
- Direct Electric Heaters – Expensive to run and really only worth considering for a small above ground pool see Electric Resistance Pool Heaters.
- Natural Gas Heaters – A popular choice, these are powerful and reasonably cost effective. Available with both electronic and millivolt ignition (electronic ignition is better for several reasons but it requires an electricity supply) see Gas Pool Heaters.
- Propane Heaters – Most natural gas heaters are also available for propane and they are identical except that the propane version costs much more to run.
- Electric Heat Pumps – Increasing popular, although they are more expensive to buy than gas heaters they are cheaper to run. Their heating capacities are lower than gas heaters so they are best suited to pools that are heated for long periods (i.e. they take longer to get the water up to the required temperature) see Pool Heat Pumps.
- Solar Pool Heaters – The most environmentally friendly option which can be effective given the right location (see Solar Pool Heater).

What size of pool heater do you need?
This is a common question which is not quite as straightforward as you might think. There are tables which give guidance based on pool size but location also has a big impact. The big enemy of pool heaters is wind (see Pool Heater Sizing and Choosing A Pool Heater) !
Where to buy a pool heater?
We looked for the best prices when we updated the site (in February 2015) and have added this information on each product page. Of course there may be special offers so it is worth looking around but beware shipping costs which can be considerable.
We frequently recommend PoolSupplyWorld.com as on many models they offer the best price, since shipping is free, and they have a wide range of pool heaters and pool heat pumps. You can also use coupon codes to get additional discounts. To see their current coupon offers Click Here.
It is also worth looking at Pools Inc who also offer good prices and free shipping but their model range is smaller.
