Description
This Thermalec 21kW electric pool heater is specifically designed for use with swimming pools and spas. The base of the heater is a fusion epoxy-coated cast iron vessel through which the water from the swimming pool flows. The vessel is fitted with a safety pressure relief valve, a drain valve and the water inlet and outlet nozzles and its base is designed to support the heater on a flat, solid surface. Four screws are supplied to enable the heater to be levelled.
The Thermalec Heater 21kW is single phase only. The flow direction is from left to right but may be reversed quite simply on-site following the installation instructions.
As a safety precaution, Thermalec electric pool heaters are provided with an interlock relay, which must be connected to the filter pump control circuit. The heater will not operate unless the interlock is wired and the filter pump is energised. This model also features a mains circuit breaker.
