no hot water

[crackapple]

Hi all, I have a problem. Since fixing a leaking bathtap i have had problems with hot water.
It is not as hot as previously and sometimes not at all. Any ideas? All help appreciated.

what did fixing it involve has the flow been reduced combi boiler or tank

possibly just a coincidence its very cold and if its a combi it will struggle to reach temps it did previous

Fixing involved replacing washers, also rehung a radiator the water was very hot previously.. Not the weather because it gas not happened before. Its a combi .

if the taps running faster than before the water wont be as hot, turn the tap down a bit for a slower and hotter water flow

il tell you exactly what you have done, when turning the cold water mains off you didnt realise that the tap wasnt fully open, You did your work then opened the cold water stop tap again but this time you opened it fully....this caused more flow which in return meant more water going through the boiler and finding it harder to heat as it passes through...add this to the fact that its very cold outside....

Seems likely. The op should throttle the stop tap down a bit

idealy you shouldopen the main fully and then shut half a turn then use the service valve on the combi to slow the hot water rate down
