immersion heater

I have an electric immersion heater which I’m only putting on now three days a week for 2.5 hours. I was wondering if this was the most economical way to use the heater. The heater has two elements top and bottom. Would it be better just to use the boost feature which I think just heats the top part of the tank or should I just heat it as I have been doing

Regards

Mark

    Assuming you are on E7 .and you are heating at night - if that gives you the hot water you want stick to it.

    Don't use the Boost
    Never pay on an estimated bill

    Depending on the size of the tanks 2.5 hours is a lot.

    Try reducing in steps and see if the water is still hot enough for you.

    Just because its turned on for 2.5 hours doesn't necessarily mean it will be drawing power for 2.5 hours, perhaps a better description would be reheating the tank 3 times per week.

    If the boost is heating the water on day rate then it'll cost maybe 250% more than the night rate.
    No free lunch, and no free laptop ;)
