We rent out a flat that we have never lived in - I have only been in it twice very briefly. It's a new-build, not a conversion - I don't know what sort of heating it has.
The tenants have reported that the shower is running hot and cold which I think means the heat exchanger needs replacing, but before I book the job I would like the make and series of the boiler so they can at least try to bring the right parts.
The tenants have got back to me twice now to say they cannot find the boiler and can I just send someone out anyway. It just seems very weird!
