Many offer dual controls which are ideal for spas, which are heated to higher temperatures than pools. How long you are prepared to wait for your pool to heat up Selecting the right size gas heater depends on three key factors: It can also heat pool water much faster than a solar or heat pump system can, and will heat the pool water up to 40oC, no matter how cold the climate is. Gas heating systems use natural gas or LPG, heating the pool water by drawing it into a heating unit and filter.Ī key advantage of a gas heater is that it is the most simple to use out of the three types, which could explain its continued popularity. Put simply, they could extend your swimming season all year round. Gas heaters are the fastest method for heating your pool, providing a comfortable temperature for swimming on demand. However, unless you live in an area that does experience very low winter temperature, this is not a concern.Īnother thing to consider is they can be expensive to initially install, but the low running costs will make up for this in no time at all. One of the disadvantages of this type of system is that they can lose their high energy efficiency slightly once the weather really cools down, as the pump has to work harder to heat the water against the outside temperature.

And the best thing about heat pump pool heaters is that they operate regardless of the weather. As a guide, you can save up to 80% over LPG and 50% over natural gas fuelled heaters. Although initially heat pumps take longer than gas heaters to warm up the pool or spa water, they are much more economical and will then maintain the heating as well as gas heaters.īenefits of heat pumps include their high energy efficiency and lower running costs. Reliable, highly efficient and economical to run, heat pumps extract heat from the air (similar to a reverse cycle air conditioner), and use that heat to produce hot water.Ĭompared to gas and electric, heat pumps use just a fraction of the energy to generate the same amount of heat. The amount of heat absorbed and the subsequent increase in temperature depends on three key criteria: Solar heating systems are also simple to maintain. Solar systems are a low cost method to heat up your pool and have virtually no operating costs, just the cost of electricity to pump the pool water through the solar absorber on the roof. This enables you to increase the amount of time you spend in your pool without worrying about expensive energy bills.

After the initial setup cost, the ongoing running expenses are minimal as heat is provided free from the sun. Unlike other pool heaters on the market, solar pays for itself in just a few years. Basically the hose acts as a solar collector, which is the process of solar heating. The sun’s energy has been absorbed by the hose and transmitted as heat to the water inside it. When you turn on the tap, out comes hot water. Imagine a garden hose that has been lying in the sun for several hours. The principals involved in solar pool heating are very simple.

Undeniably the most environmentally friendly option of all, solar pool heating operates by using the energy of the sun.
