MEDDINGS THERMALEC
Meddings Thermalec® are the manufacturer of high quality swimming pool heaters that are unique in design. 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 HEATER RANGE
12 THR
Cast in BS-EN-1561-1997-ENGJL-200 iron, with a heavy fusion bonded epoxy coating impervious to chemically treated pool 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. A 1/2" drain valve at the lowest point allows the heater to be left empty in winter. Flow connections consist of easily removable uPVC stub flanges into which the pipes may be fitted using suitable adhesive, as the flanges can be released easily from the heater no unions are required, nor is any form of heat sink needed. Flow direction is from left to right, but may be reversed quite simply on site following the installation instructions.
Electrical Data
Protection level: IP 21
Fuses: 1 x 2 Amp (+1 spare)
Pump interlock voltage: 230 V AC
Element heat flux: 11.5 W/cm² max.
24 THR
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 unit will not operate again until both the safety thermostat and the breakers are manually reset. The operation of the safety thermostat switches off the working contactors before energising the in-built shunt trip of the breaker, giving the unique Thermalec double protection against overheating and damage to the elements.

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.
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.

TESTIMONIALS
About 38 years ago I decided to build a swimming pool. Having built it my next concern was the best way to heat the pool.
I actually built some solar panels but found that I would never be happy with their performance and the lack of control because of the fluctuating UK weather conditions. My next thought was a Heat pump which were reported to be more efficient, but all those years ago Heat pumps were in their infancy and had not been on the market long enough to have been tested thoroughly.
I felt that I needed a heater that I could rely on and that I cold fully control to my requirements in all weather conditions..
I therefore decided to purchase a Thermalec heater. From the moment I received the heater I was impressed with the construction and build quality. The electrical and electronic parts ,the tidiness of layout and fixing points were beyond belief.There were no loose wires or components flopping about, everything had been placed and secured properly.
All in all a very technical well made unit.
Reliability since new has been incredible. The heater has never broken down and always performed well to the settings I required. I have only had the heater serviced 3 times mainly as a preventative measure.
On one service I decided it best to have a new heating element installed and no other problems or issues have arisen.
I simply can not say enough about the service department team. Discussions over the telephone or on the odd occasion a visit to your works has always been friendly, constructive and informative.
In hind sight I can only say that I definitely made the correct decision in buying your Thermalec heater. Im sure you can see from the above comments that I am more than happy with the heater and I can only hope that the heater will continue to perform in future years.
