What about other solutions to heat my pool?
Yes, there are other types of heaters out there. Most of them don't make any sense when looking at dependability, operating costs and eco-friendly character. In the end, it's your choice so we at least want to provide you with the information you need to consider.
Here are four main types of pool heaters:
- Heat Pump
Solar pool heaters
These are efficient in southern climates year-round and can extend swim time in northern climates. By using the sun's energy the existing pool pump will circulate the water through the heater which will be typically located on the rooftop or on a frame constructed in the yard.
The downside is that Solar heating requires a system equal to 50%-100% of the pool's surface, and needs sufficient sunshine to work effectively. Also be aware that these systems will require correct maintenance as they are fragile for leaking. While solar energy may be free, the pool pump must be running for the solar heater to properly operate which will increase your electric bill.
Gas Pool Heaters
These run on either propane or natural gas. Operating independently of outdoor temperature conditions, gas pool heaters burn the fuel within a combustion chamber all while your pool water runs through copper coils to then return to the pool warm. They are ideal for cold Northern climates.
The downside is that this kind of heating is very inefficiënt, extremely expensive and ecologiclally unsustainable.
These are devices that convert electric current into heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy. Similar to a small water cooker, a lot of electricity is needed in order to actually heat the water flowing passed the resistor.
The downside is that this kind of heating is again, very inefficiënt and expensive. Even using EV solar panels, it will consume a huge amount of electricity that far exceeds the potential of roof installed EV solar panels. Depending on your electricity provider, the provided electrical power might be ecologically sustainable (wind, solar -or water generated) or unsustainbale (nuclear plant, gas plant, coal plant, ...).
This system is actually a form of solar energy that is also widely advised as an ecological and efficient domestic heating solution. It uses a small amount of electricity to extract heat from the air and transfer it to the water. In the ideal world, a few roof-installed EV solar panels compensate for this consumption.
How is that possible? Well the sun warms the air and that heat is pulled from the air. Even on days without sunshine, this warm air is pulled in, enhanced, and transferred into the water. In order to run efficiently, a minimal temperature of approximately 10ºC is needed. This is very low, meaning your heat pump will still efficiently function on cooler days.

Why does Poolworx only offer heat pumps?
While solar-only based systems (such as the solar pool heater) may be "free" you still have to leave the pump running a very long time in order for it to function, boosting you electric bill by €300,- to €950 a year. Costs to operate Gas and Electrical heaters can range from €300 to €500 per month and can easily amount to a lot more, depending on the fuel or electrical costs.
Electric Heat Pumps are highly efficient and are costing their owners on average €25-€90 per month, for an 8x4 pool, depending on climate and usage conditions. This makes sense, and so do we.
We find that about 9 out of 10 of our site visitors who are looking to install a pool heating solution, choose heat pumps simply because of their dependability, low operating cost and eco-friendly character.
