Thermalec Electric Heaters

  • 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.
  • Heavy duty nickel plated copper sheathed elements to BS-EN-60335-1, with low Watt density for long life, are mounted individually in a removable top plate, which allows complete inspection of the interior of the vessel.

 

Features

  • Thermalec heaters are made from Titanium to make them longer lasting and reliable.
  • The construction of the heater is solid and robust, to ensure years of safe and reliable service.
  • The contact materials are highly resistant to corrosion from pool chemicals. Thermalec® pool and spa heaters can safely be used with sea water pools as well as in demanding applications such as Hydro- and Thalasso- therapy.
  • The watts density of the heating elements is very low (9.54 W/cm²), ensuring minimal scale build-up and long element life.
  • The heating elements are always submerged in water. Any air bubbles entering the heater pass through it above the water and across the unheated parts of the elements, preventing any damage to the latter.
  • The patented weir and baffle system inside the heater causes the water to flow through it in a spiral. This increases uniformity of the water temperature inside the heater and prevents direct impingement of cold water onto the elements.
  • The spiral flow regime of the water inside the heater discourages scale formation, extending element life.
  • The heaters have no flow switch. These are notoriously unreliable. Any air bubbles passing through the heater will cause any flow switch to make and break repeatedly in rapid succession, causing the contactors to do the same, thus shortening their life.
  • Thermalec® heaters are flexible: The water flow direction is normally left to right. If required, this can be easily changed on installation by means of a simple modification. Most models may be easily changed by a qualified electrician from single to three phase operation and vice-versa.
  • The thermostats used in Thermalec® pool and spa heaters have a low operating differential. This is essential to maintain the swimming pool at a virtually constant temperature.
  • Heaters with higher operating differentials are likely to allow the pool to cool to an uncomfortably low temperature before switching the heating on.
  • Top quality contactors have been used and their ratings generously selected to give a long service life and minimum risk of operational problems, particularly in pool plant room conditions.
  • As a safety precaution, the heaters are provided with an interlock relay, which has to be connected to the filter pump control circuit. The heater will not operate unless the interlock is wired and the filter pump is energised.
  • Status indicator lamps on front of panel to facilitate troubleshooting and diagnostics. Thermalec® pool and spa heaters comply with all current and relevant EU regulations and directives. Thermalec® pool and spa heaters have a two-year guarantee.

Operation

Before switching any power on, it is ensured that the heater is full of water and that water is flowing through it. The mains power is then switched on, followed by the on/off switch on the heater. A red indicator shows that the heater is powered. An amber light on the heater indicates that the filter pump is in operation. If the pump does not operate or if the pump interlock has not been fitted, the heater will not heat.

The desired pool temperature is now set using the thermostat dial. A green light on the heater indicates that the heating elements are powered and water is being heated. When the set temperature is reached, the green light is extinguished. A white light on the heater indicates that the water temperature is below the factory set safety thermostat trip level. If this temperature is reached, the heater has overheated. In this case, the safety thermostat trips and the unit is shut down. This trip must be reset manually.

In normal operation, the green light will only be lit (and heating will occur) if all the other lamps are lit and the pool water temperature is below the set temperature

Please note - all Thermalec Heaters are 'special' order items which would be dispatched directly from the supplier.
