Immersion tank replace or fix

[Chrissie 70]

My elderly mum has an immersion tank that has been cold for 6 months. She has oil fired central heating with a thermostat/timer for heating only. There was hot water before but not sure how it was heated. I have had an electrican look at the thermostat and plumber also checked but cannot fix the problem. Would it just be easier to replace the immersion tank with new thermostat , but does the hot water get heated by the boiler in the garage but because maybe of fault with tank not store the hot water. I dont understand does the hot water then go direct to the radiators only ? Confused what to do next can anyone explain how this works. Thank you :disappointed:

Welcome to the forum

I think you need to get a different plumber/heating engineer. It could be a couple of issues.

If you post your location in the country, there may be somebody on here who could go and have a look.

If it's a timer for heating only, sounds like gravity hot water primaries. You need someone who knows what they are doing with these. Has she had any work done on the system recently? Was it a sudden stop or gradual?
