Electric swimming pool heaters

How does the electric pool heater work?

Basically an electric pool heater consists of a heating element which is inserted to the water flow of the swimming pool pump system. The water enters through one port of the front water header. Then the heat is derived from the electric coil that is immersed in the water flowing through the unit and then the heated water goes out of the other port. The tubes are made of copper due to its excellent heat conductivity, there by transferring the heat effectively to the water. However, improper water chemistry can easily attack this soft metal and dissolve it into the heated water. That’s why we also offer titanium pool heaters which are bullet-proof to various kinds of chemistry. Any swimming pool will require a pump that keeps the water circulating. All you need to do is insert the electric swimming pool heater in the water flow and begin electric swimming pool heating. The electric pool heater can only work properly when the pool pump is activated. The pump has to produce a water flow which is strong enough to run the pool heater. If the pump is inactive: the pool heater is delivered with a flow switch which will shut the pool heater off as long as the pump is not working. Get also an annual maintenance check-up. A maintenance check-up does not cost a lot and a properly tuned electric swimming pool heater will operate more efficiently! The annual pool products maintenance check-up can prevent unpredictable damages and can save you money in the long term.

Cost of electricity in different European countries

Operating cost of swimming pools vary due to various aspects. Temperature variations in different countries for example can influence the heating costs. But also the electricity tariffs are influencing the operating costs of a swimming pool. To save money on heating the swimming pool you should heat your pool water at night. Special night tariffs can help you reduce heating cost. Inform yourself about your night tariffs by contacting your electricity provider.

Size of electric swimming pool heaters

For cost and energy-efficient swimming pool water heating, you will also need the right size of electric pool heater.

An undersized electric pool heater will heat too slowly, and an oversized electric pool heating device will do the job but will increase the cost of the installation.
