Economical to run, quiet and unobtrusive, easy to operate, safe and simple to install - all these are true of a Thermalec electric heater for your swimming pool or spa.
Thermalec heater systems will keep your pool at a constant temperature level throughout your chosen swimming or spa season, efficiently and economically.

Note: 7.5-24kW heaters are wired for single phase, but are also supplied with an on-site adaptor for conversion to three phase. 48-96kw heaters are available to order.

The unique way to heat your pool
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.

Thermalec is guaranteed to hold its thermal efficiency for life, without regular cleaning or de-scaling.

An On/Off switch is provided to the control the main power to the heating elements.

Standard Specification

HEATER BODY:
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.

HEATER ELEMENTS:
Heavy duty incoloy 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.

CONTROLS:
Heavy duty contactors control the power supply to the elements. The contactors are switched in turn by a filter pump interlock relay, a pool temperature controller with less than 1°C differential, and a manual reset safety thermostat to operate before the temperature reaches 53°C. The control circuit is protected by a 2A fuse. A minimum of 6 indicator lights monitor every stage for simple diagnostic servicing. The controls are mounted in a plastic coated steel enclosure above the heater body. Cable entry is through a removable plate in the rear panel.

The Thermalec sizing chart is for outdoor swimming pools in the South of England, running from the beginning of May until the end of September. For swimming pools in the North, multiply the heater size by 1.3 - 1.5 depending on the exposure of the pool. The figures shown for capacity of the pool - in gallons or M³ - are based upon an average depth of 4'6" (1.36m) and are provided as a guide when an exact surface area is not known.

Indoor pools: providing the indoor air temperature is maintained at least 1°C above the pool temperature by an alternative form of heating 24 hours per day, the heater size may be reduced by multiplying by 0.7, but since running costs are related to the size of the pool and the temperature required, not the size of the heater, we advise keeping to the table where possible.

In countries where off-peak electricity is not available, heaters sized at 1kW per 1000 gallons (4500 litres) with the heater operating 24 hours per day, will normally be adequate and will give an 8°F (4.4°C) rise in 24 hours assuming no losses
