Tank works but no hot water coming theough

[Salbs]

My tank is heating water up but it's not coming through to taps or showers. It started as just the kitchen tap but now it's all of them. Any ideas? Thanks

if you have a tank in the loft then chances are there's a problem with the ball valve ... first thoughts ... Do you have any tanks in the loft? Do you know if your cylinder 'tank' is vented or unvented?

Have you had any work carried out recently?

My tanks under the stairs (live in an apartment) not had any work done. My husband thinks it's the blending valve??

I think it's unvented but nit entirely sure, how could I check?!

Take some photos and post on here.

Why do you think it's a blending valve?

Also to clairfy do you mean no water is coming out of the taps at all or just no heated water is coming out?

It should have a name on it somewhere 🙂

Are you getting plenty cold water at the taps?
