Calling All Plumbers.

Zoomup

I was recently called to an immersion heater problem. The top entry 27 inch immersion heater was installed in a new copper cylinder that was much higher than the immersion heater length. I reckon that a 36 inch immersion heater could have been installed. What was the logic of installing a new copper cylinder where the bottom quarter of cylinder water will never be heated?

    Assuming it is not in the middle at the top, pointing directly downwards, it will be at an angle. You don't want it too near the walls at the bottom (3 to 6 inches is good), also you don't want it very near the indirect coils, if the cylinder is also heated indirectly.

    The only way to know for sure is ask the manufacturer of the cylinder what length they recommend for the model of their cylinder, or find instructions online.
