I have a ground source heat pump at my rented property and when it was being installed I was told you still leave my immersion heater on all the time. I have searched Google but I cannot find any information on if this is correct.
I have no clue how it is set up but surely I want to use the ground source energy to heat my water and turn on the immersion if I need a boost. Or is the system clever enough to only turn on the immersion when it requires it and uses the ground source normally?
I am only asking as I am currently trying to find the reason why my electric bill is so expensive, my fixed tariff runs out next month and my proposed new tariff is extremely scary when it shows my expected monthly costs of £358 on a standard tariff and £450 on a fixed. I'm currently trying to find out what is costing me so much so I can sort it.
The house is a big converted barn and not overly efficient but I still cannot understand the costs here. Anyone that can help would be greatly appreciated!
