Rather than using the immersion heater to boost hot water, an external heat source e.g. a boiler can be used by making use of the
multi-function relay wired to the boiler hot water controls.
I t may be desirable to use a de-stratification pump to mix the cooler water at the bottom of the cylinder with the hotter water at the
top, this allows a top mounted immersion heater to heat all of the water in the cylinder.
