Electric water heaters steel or plastic housing.
The perfect solution for small swimming pools and bathtubs. The operation is similar to that of the exchanger, but instead of a coil there is a heating element.
When using the heater, make sure that the heating element is not damaged. This is due to the high calcium content in the water, a large amount of disinfectants, and bad electrical and hydraulic connection.
It is recommended to use this solution when another solution cannot be used. The running costs are high.
