Oil fired boiler and immersion heater

Anonymous user 3 March 2024 - 3.44 PM

Just moved into a house last month (our first home) and there is an oil fired boiler outside, and the water tank has an immersion heater fitted in too. I had assumed the immersion heater was a backup for if the oil ran out, however if I turn this off then we run out of hot water. With electricity prices as they are, I really don’t want to rely on this expensive method of heating, but I also obviously can’t be without hot water. Is this a normal set up for the system? Is there any way I can just rely on heating oil and not on the immersion heater? Edit: thank you all for the answers below! Aureus Energy Group’s answer helped, I got a plumber out and they said that the cylinder stat was faulty and have replaced now. Thanks to everyone!
