Our boiler is an oil-fired Worcester Heat-slave 20/25 in a newish (7 years old) four bedroom house.
Normally it works admirably on the central heating plus all downstairs sinks and washbasins
Upstairs it works fine in the washbasins but only on one of the baths.
The other bath runs hot as long as you adjust the hot tap to a very low flow rate and add the cold water afterwards. [If you try to run the hot tap at a fast rate the water runs tepid. If you run the cold tap at the same time as the hot that also end up with a tepid bath]
Any ideas as to why please?
