BOILER UPSTAIRS IS THIS RIGHT?

[LITTLEGEEK]

Hello looking for some advice. My boiler is upstairs but the main thermostat is downstairs in the lounge. I've had a few problems with it and had the heating engineer out who replaced the thermistor (2nd time).

Reason being, central heating would be coming on but the little flame didn't show on the thermostat to show it was on you know eg its set for 16 but room temp is 16/17. I only knew it came on because I noticed the radiator on.

This happens a lot if I turn heating temp down on thermostat and open windows all over house. Hot water also takes a while to heat up. I commented that upstairs was always roasting but downstairs never seemed to heat up and he suggested turning off the radiators upstairs to 'force' the heat downstairs.

Last time engineer was out he said I probably had a leak in my shower or washing machine as he could hear running water when the water was switched off.

So got plumber round to check but he didn't know what he was talking about and said if there had been a leak it shouldn't have affect boiler.

So bit long winded but here is my question. Should I move the thermostat upstairs? or am I likely to have a leak somewhere.

TIA will have to check back later as got to get to work.

our boiler is in the attic, thermostat is downstairs - we've never had any problems. are you covered by a service contract? the gas men really should be offering you a thorough diagnostic rather than just taking guesses. I'd ring your supplier

If you put the thermostat upstairs where it is read hot the radiators would never come on as it will be taking that upstairs temp. You'd have to set it to 30 degrees or something daft to get them them to come on.

My boiler is upstairs and thermostat in the hall downstairs, never had a problem.

Perhaps your downstairs radiators need bleeding?

Your Water supplier would be able to tell you if there is a leak anywhere or talk you through a test to do yourself.

Our boiler is upstairs in our bathroom. Thermostat is downstairs in hallway. Works well for us!

the thermostat can go anywhere in the house, it doesn't matter.

you mentioned that radiators get hot when room stat says off, and that hot water also takes a while to heat up. Have you got a hot water cylinder? What colour is it?

Have you got a water meter?

Is your heating engineer over 14?

Hiya everyone, on tea break, thanks for replying. It's a combi condensing boiler so no cylinder. Not on a water meter and it's about 6/7 years old.We got it put in when we moved in as old one was condemed.

I do have a service contract and I'm sure that includes an annual service but they have not been in contact to arrange one. Not sure if that's because I'm supposed to chase for it or if it's because they have been out to fix the problem. I'll need to check my policy.

I know they sent a subcontractor out it was a different company who came out this time than the original provider but that shouldn't make a difference I would think.

Thinking back it has had the thermistor replaced twice and a circuit board once. I'm not sure if that is average for a boiler this age.

absolutely not average for a boiler only 6 years old. Ring them for a service.

if the radiators come hot when the room stat is off:

turn off the rads at the room stat or timer (not at the radiator valves, leave them open). Wait for them to go cold, and feel them all.

Turn on the hot tap to fill the bath. Walk round and feel the rads. Have they started to warm up? (feel the inlet pipes first)

if so you probably need a replacement diverter valve in the boiler. If so ask your engineer what his favourite subject is at school.
