THE UNIQUE WAY  
TO HEAT YOUR POOL 
Thermalec® are the manufacturer of high quality swimming pool heaters and are unique in design as Thermalec heaters will operate with water coming from the filter at high velocity without it striking the heating elements directly due to our unique baffle system which is part of our original patent. Our marine and tropical aquatic heaters are designed to have no copper in them which is essential to maintain your fish's life span.

Reducing our Carbon Footprint. 

Thermalec as part of the Meddings Group of companies have invested over £250,000 in Solar Panels and a Biomass boiler at their Ivybridge facility to reduce their need of a conventional power supply. The solar panels supply 50kW to the manufacturing division and supply the national grid with surplus energy. 
The Hargassner 200kW Biomass boiler has eliminated our needs for fossil fuels to heat our factory. We now only use a sustainable fuel supply. 

Thermalec caring for our future

Thermalec swimming pool heater 12 PHR
Cast in BS-EN-1561-1997-ENGJL-200 iron, with a heavy fusion bonded epoxy coating (Scotchkote 206N) impervious to chemically treated pool water and sea water, constructed in accordance with British Patent 2.092,282 Design pressure of 35psi (2.46kg/cm2) with 3/4" safety valve(s) set to operate at the maximum normal working pressure of 30psi (2.1kg/cm2) giving protection to both the heater and and the installation as a whole against over pressure.  
24THR 
Thermalec swimming pool heater 24 PHR
Circuit breakers are fitted instead of the On/Off switch and protect the heavy power circuits against short circuit. These not only act as the main switch, but in the event of a water temperature rise within the heater being sufficient to operate the safety thermostat, a trip is triggered within the breaker such that the heater is totally isolated at its point of supply. 
36THR 
Thermalec swimming pool heater 36 PHR
Fitted with a thermometer to indicate the outlet temperature, which enables flow rates to be adjusted when heaters are either fitted with a by-pass, branched off a much larger flow pipe, are used in multiples or are operated in parallel with an alternative means of heating. 
72THR

Circuit breakers are fitted instead of the On/Off switch and protect the heavy power circuits against short circuit. These not only act as the main switch, but in the event of a water temperature rise within the heater being sufficient to operate the safety thermostat, a trip is triggered within the breaker such that the heater is totally isolated at its point of supply. 
120THR 
Thermalec swimming pool heater 120 PHR
Additional to the specifications below. Circuit breakers are fitted instead of the On/Off switch and protect the heavy power circuits against short circuit. These not only act as the main switch, but in the event of a water temperature rise within the heater being sufficient to operate the safety thermostat, a trip is triggered within the breaker such that the heater is totally isolated at its point of supply.

The ZENITH range of swimming pool heaters is in keeping with the intrinsic values of Thermalec® heaters, with its robust cast iron water vessel housing the new Titanium 825 8kW heating elements. ZENITH is designed with Thermalec's unique spiral flow to allow the pool or spa water to flows through the heater to reduce scales build up.
