    Hi

    I'm new to the forum so apologise if this subject has been covered previously. We have recently moved into a new to us house and have a query with our hot water system.

    The gas boiler we have lives on the floor in the attached garage. Upstairs in the bathroom we have an emmersion heater. However, the emmersion switch has been off since we moved in a couple of months ago and yet we still have hot water. The timer controls for the boiler show HW and CH options and the HW options are set to come on and off through the day. Is the boiler heating the water in the immersion tank? I always thought emmersion heaters were run on electric. Confused!!

    Also, is this method of heating water very expensive. I have heard that emmersions are costly to run.

    Thanks in advance

    The gas boiler is heating the water in your cylinder and the electric element is just a back up if needed.

    Out of interest why does the original description lead you to this conclusion?

    Lilee, the immersion is the element that actually heats the water, the tank that holds the water is known as a cylinder, I think that you are getting your terminology muddled :oops:
