My central heating system is working perfectly but I have no hot water coming from my cylinder in hot press it is cold. All radiators are hot. What could be the problem?

No hot water is coming from my hot water cylinder. All radiators are operating perfectly. What could be problem?

Is it just the one sink that isn't giving you hot water? Do all other sinks and tubs give both hot and cold?

No hot water in any of the hot water taps

Do you have a seoarate hot water heater or does it come from a combi boiler?

I do not have hot water in any of my hot taps even radiaters are hot.my indirect cylinder is cold all over. How can this be?

I think we are on different sides of the pond, our vocabulary doesn't match too well. I do not understand the meaning of indirect cylinder, is it s separate hot water heater or part of your home heating system? Where do you live Mike?

I live in Ireland. My indirect cylinder is part of my home heating system which is heated from a boiler. In the indirect system circulation is from the boiler to a small cylinder known as a calorifier set inside the main hot water cylinder. Therefore water in the main cylinder is heated indirectly by the calorifier and is piped to the hot water taps. What can be wrong when there is no hot water in the hot water taps in the house despite the radiators being hot.

Sorry Mike but I have zero experience with this type of system. Maybe someone else will drop in who has worked on one.

Good luck, Bob
