AdamW Posted February 25, 2007 Report Share Posted February 25, 2007 Guys Any plumbers out there? I seem to have a problem with hot water firstly the system is about 25 years old and is a normal central heating system combined with hot water the hot water is on when the heating is on....... my problem is hot water.. it has started to play up.. yesterday we had no hot water, but heating is working fine? i don't have an immersion heater in the tank.. it is feed and heater from the boiler then today i have hot water but need to turn up the heat on the power shower to get some normal heat out of it (much higher than normal!) now i know i live in a hard water area and the tank needs replacing, this leads me nicely onto my next question, would my tank be a "direct" or "indirect" tank? i have no idea, but want to replace it.. help Adam Quote Link to comment Share on other sites More sharing options...

Check your Central heating pump as if it is an indirect system the hot water has to flow through the pipes in the boiler to heat the water. No Circulation no warming Could ALSO be an Air lock or blockage in the heating coil. Have you not got an Imersion heater fitted for back up?

Mungler Posted February 25, 2007 Report Share Posted February 25, 2007 Sounds like a check valve. I ain't a plumber but whenever mine has gone up the swanny, it's the check valve. So, applying Mungler logic, it's your check valve. Quote Link to comment Share on other sites More sharing options...

al4x Posted February 26, 2007 Report Share Posted February 26, 2007 I was thinking it would be the motorised valve till you said it was working this morning. best get up into the loft and check the tanks are full as it may be as simple as needing a new ball valve. If not its worth checking the motorised valve we had this on our last system and you can usually override them. Trace the hot pipe from the tank and you should see a box on it with a wire coming from it. If it has a metal lever out of the top of it then you can check this moves when heating the water if not you can manually move it and usually trigger the water heating that way. best bit is if its at fault they are about £8 and dead easy to change. As for the new system it depends what you are getting for the money we had a large combi fitted in our new house with rads and all new pipework etc for £2800 all up. the combi is great as it does away with the hot tank and all the loft tanks which frees up space and also is more efficient. If you have multiple bathrooms etc it may not be a good idea but ours is a huge improvement over the antiquated aga based heating system it replaced.

magman Posted February 26, 2007 Report Share Posted February 26, 2007 i am a plumber and bet its a dry expansion tank in the roof space :blink: now that will cost you £60.00 would my tank be a "direct" or "indirect" tank? i have no idea, but want to replace it.. do you have 1 or2 plastic tanks above it or in the loft ?

AdamW Posted February 27, 2007 Author Report Share Posted February 27, 2007 I bet it was the check valve. Incidentally, what is a check valve. :blink: Guys, Still not at the bottom of it, tank in the loft is fine, going to replace the hot tank today, due to hard water and imminent boiler change, and cost reduction... all was OK again today, no check valve on the system it older than that! so could be feed from boiler that heats the water.. god knows... waiting for BG to call me back re price, as hot water tanks was on there list to do for £350+vat, so is an earth bonding check (ME Bonding) for £120+vat, both of which i can do or know someone...... Will let you know how we get on.. please leave mobile numbers and call out charges below...... :blink: Adam Quote Link to comment Share on other sites More sharing options...
al4x Posted February 27, 2007 Report Share Posted February 27, 2007 Don't whatever you do get British Gas out, they are absolutely extortionate. My sister had them quote on a 1 bed tiny house and it was nearly 5K for 4 radiators and a tiny combi boiler!!!! Motorised valve is the next thing to check you'll find it when you change the tank, if its not opening you'll have no hot water whatever you do.

AdamW Posted February 27, 2007 Author Report Share Posted February 27, 2007 Well hot water tank now changed, although I am sure its not the problem, but with the new system going at some point subject to price, it will on help..
