as a conventional above ground swimming pool 15 ft dia heater (electro) is just
a heating chamber, cold water in one side passing over internal heating element
and warm water out coupled into the filter system with a temperature control
and safety cut out is there any reason why a shower unit could be used instead.
They have the same features and reqirements and the filter pump delivers the
necessary flow rate. They come in 3kw, 4.5kw for this size pool. Coupling the
shower unit to the filter pump water circulation is not a problem nor is the
electrical supply in this instance. The only difference that I can see is the
price (£300+ for the pool heater as opposed to anything from £50 to £100 for a
shower unit that meets the flow rate and KW requirements) Is this possible do
you think or an impending DIY disaster! I would be most gratefull for any
guidance offered before I take the plunge, so to speak. My plumbing and wiring
skills are now more than sufficient to tackle this so that is not a problem.
