Thermalec pool heaters are unique in that they will operate with water coming from the filter with high velocity without it striking the heating elements directly. Instead, the water is deflected by baffles, forcing it round the curved base of the heater.

Unlike conventional pool heaters, the Thermalec is guaranteed to hold its thermal efficiency for life, without regular cleaning or de-scaling. This means your running cost will not increase with time and maintenance costs are drastically reduced.

No need for expensive compulsory annual inspection required by fired boilers. Using low cost electricity such as Economy 7 ensures not only one of the lowest cost methods of heating your pool, but because the filter pump runs on the same low tariff for the same period as the heater, filtration costs can be cut by as much as two thirds. If you need a heater, you need a Thermalec. No constant noise, no fumes, no flames, no emissions, no fans, no fuss... just perfect water conditions and maximum enjoyment.

The safety thermostat measures the temperature of the water as it leaves the heater, providing perfect safety for bathers. A temperature rise within the heater, due to poor water flow conditions, is rapidly sensed by both the control and safety thermostat.

The unique cup-shaped base design ensures that the heated part of the element is always kept beneath the water, even if the flow from the pump fails. Flow failure simply allows the water in the cup to heat up and switch the heater off instantly using the normal temperature controls. All heaters 15kW and above have circuit breakers as well as the working contactor, which are switched off by excess temperature.
