    Can I get a COMBI with a 15mm gas connection?

    Thanks guys. At least 12 meters from the meter to the kitchen. I guess I'm a bit panicky as its going to completely die soon, so didn;t think to use the search! Reasonable... meaning semi-hot? Sounds like I should go for the 28kw just for shower use. Cheers, Sparky

    Can I get a COMBI with a 15mm gas connection?

    Hello All, I have an ICOS M3080 24kw system boiler on its last legs. The Heat exchanger has started leaking and the boiler is now occasionally failing to fire up. As the heat exchanger would be costly to repair, and as the boiler is around 10 years old, it wouldn't make economical sense to...

    Wiring Help For Wireless Thermostat Honeywell CM927

    Simond you are 5*****! Just wired it up and testing it as I type. All looks well. :) I bought the Homexpert THR872CUK from Amazon (wanted warranty/amazon service), its very similar to the CM927. Although with this model the front flap comes off and with the CM927 it folds up, minor gripe...

    Wireless Control. CM927 Shall I?

    I’ve been looking at the threads and before deciding on purchasing what appears to be the commendable CM927 wireless receiver and thermostat. I have a few questions of my own. I did some various tests recently and have found to my surprise no change in the gas units being used when changing...

    Noisy Loft Water Tank.

    Is there anything else I can do apart from the lagging? I.e. just seen the below part mentioned in one of the forum threads. Though not sure if it’s any different to the one in my pictures and if any less noise gain would be achieved. I installed a Dudley hydroflo in my cistern over the...

    Noisy Loft Water Tank.

    While I'm on my upgrade flick... Any ideas on how I could reduce the noise when the tank has been drained down after a shower/bath. It’s fed by 15mm direct mains. It’s quite noisy when the water refills. Not sure if the brass section contains a flow restrictor/reducer as I never installed...

    No room thermostat just TRVs. What would happen if...

    Must admit I haven't seen anything like that. I will have a closer look where the boiler is housed. Though as everything so far seems to be in order with the S Plan setup, albeit the bathroom rads turning on when the water is turned you would think/hope it was installed somewhere. For the...

    No room thermostat just TRVs. What would happen if...

    And I was all excited when I took those pictures. :roll: Thanks for the advice on not upgrading the 15mm pipe to the tank. Right at least I now know for sure its an S Plan. Nope, those pipes don't have insulation. In fact the whole loft needs to be done as the depth isn’t quite...

    No room thermostat just TRVs. What would happen if...

    Valves and auto air vents I seem to have many of these manual air vents. Is it worth changing them all to auto vents? Though why are there so many! I would need to do an additional 8 - 12 vents if I were to convert. Valve 1 Valve 2 Storage Tank. Fed by a 15mm...
