Water running cold

[col999]

I have a Brittony water heater. The water from it has started to run a lot colder than before but everything 'appears' to be working properly.

The manual says that the water governor could be sticking and therefore remove, clean and replace (all of the other options in manual I have checked). Is it safe to do this by just turning off the water or do I have to turn off the gas as well?

Any advice welcome.

Sometimes it is just because the cold water from the mains is colder (ie ground temperature) and the boiler is struggling to get temperature up to what you have been used to. The water throttle has to be turned to reduce the flow of water. Perhaps obvious I know, but worth a mention.

I must get a life

Thanks for that. Is the water throttle something easy to recognise and turn down? I least I can check that out.

However the water tends to run colder then heats up for a couple of minutes then runs colder again. Also I have never noticed a drop in water temperature when the outside temp has dropped before.

And also, your reply was not that obvious. I'm completely re-doing my house and I'm now good at brick-work but just learning plumbing

Sorry, I assumed this to be the britony 11 water heater, I should have asked first.

If you have not noticed any increase in flow rate and have not (or anyone else for that matter) turned/touched the flow regulator (ie more water flowing more quickly) and the water is not as hot as you remember it to be, perhaps the heat exchanger is getting scaled up (like a kettle does over time).

God this gets complicated to write down.

If it's the one I'm thinking about it has two large white dials in the front, one does ignition the other is the flow regulator. By turning the flow regulator when the boiler is running, you must be able to tell if the water flow increases or decreases whichever way you turn it.

Help, anyone

The water govenor as you first said can be cleaned, turn off the water and gas first.

See, I told you I was just learning plumbing

It is the Brittony II and now you mention the two dials on the front I know exactly what you are talking about. When I get home I will reduce the flow and see what happens. Funnily enough, I have noticed that the flow rate increased at about the same time as the temp dropped.

I really appreciate your help and when I start my plumbing and CH business I'll give you a call

I always knew I should have married a West Country girl

Ha! I'm married to a liverpudlian but living in the west country; now that is interesting!

My original question about the gas was because my wife is not keen on me messing with gas If I could remove, clean and replace governor (after I have now tried flow rate!) without touching gas supply that would have kept her happy. I know it's just a turn of the valve on the pipe but she has images of house orbiting earth

thanks again
