    Best way to reduce combi noise?

    You know what, you're right. I didn't know we could move the soil pipe. But, looking again at the bathroom, we'd hoped to re-do it in a few years to replace the bath with a shower cubicle (due to various reasons). So, perhaps we could block up half (or all) of the single-glazed window and...

    Best way to reduce combi noise?

    Thanks. Sadly our bathroom wall is half window and the other half is the toilet which has an air brick above it and the soil pipe runs up the middle. So the boiler can't go in there. I'll try and think of a way to alter the kitchen layout to leave the boiler in there. Currently my flue goes...

    Best way to reduce combi noise?

    We're thinking of having a rear extension on an old, small mid-terrace. We will have to move the boiler either in to the extension or in to one of the small occupied bedrooms next to the bed. The extension would be used as a living room with a new boiler either near the tv or near the sofa...

    Replacing downlight transformer that says it is 24v

    We have a downlight transformer that I believe has broken. It powers a single GU5.3/12v bulb. However, when I took the 20-year-old transformer from the ceiling it has a post-it note stuck to it saying "24V" (where I had expected 240V) with two lines below that wires saying "N" and "PH"...

    Nest+need new opentherm wiring (keep existing programmer?)

    Thanks for the info, I didn't realize that the aluminium plates would corrode more at lower temperatures when condensing; with one post suggesting the Ideal training course said theirs lasts ten years. Great. So, in fact, connecting OT would request lower temperatures by default, thus causing...

    Nest+need new opentherm wiring (keep existing programmer?)

    Thanks everyone for more to think about. My boiler is an Ideal Logic system boiler, installed this year to replace a very old (G-rated?) boiler, so I don't yet know what my gas bill will be; gas company estimates 550 so I'd hope lower at 450. The only reason I was re-interested in Nest was that...

    Nest+need new opentherm wiring (keep existing programmer?)

    Good question. I see figures banded around of "save 10-15% over a regular thermostat". So, I was figuring that if it was really half at 5-10% then I could save 25-50 pounds a year, then Nest could break even after say five to ten years. That's acceptable to me given my old thermostat has been in...

    Nest+need new opentherm wiring (keep existing programmer?)

    Although, if the Nest Heatlink is wired in the airing cupboard, and the kitchen programmer removed, then would there be existing spare wires going from the old programmer to the airing cupboard that could be used to carry OT signal from airing cupboard to the old (to be removed) programmer, and...

    Nest+need new opentherm wiring (keep existing programmer?)

    Ah, I do have a wiring panel in the airing cupboard connected to the 3-way, etc. So, kitchen programmer would be removed (and cables linked together so airing cupboard still wired to the boiler); then new controller wired in airing cupboard to that wiring panel. Make sense. But, say the Nest...

    Nest+need new opentherm wiring (keep existing programmer?)

    On the evohome customer page, it says since I currently have a single zone I'd need wi-fi base pack (249) and hot water kit (85). For multizone I'd then add a trv per radiator (60) when I could afford it. Presumably it's a case of the installer disconnecting the existing programmer, wiring the...

    Nest+need new opentherm wiring (keep existing programmer?)

    I have an Ideal system boiler (which supports opentherm) in the kitchen, cylinder upstairs on a 3-way valve. Existing digital programmer is on a diagonally opposite wall to the boiler in the kitchen (does not support OT, wires go an unknown route); analogue thermostat in the living room. With...

    Nest for elderly (first thermostat)

    My parents have a non-condensing Optima 701 combi boiler in the airing cupboard on the landing. There's no room thermostat. A programmer is on the boiler but is not used (they turn boiler CH on/off when needed). I'm thinking of trying to get a Nest for them and getting it professionally...

    Intergas RF 36 benefits over HRE 36 or OV

    When my installer came around to check pipe runs and firm up the estimate, we encountered a few problems that none of the quoters expected. Nothing that can't be resolved, but it requires more work than we expected. So, we're thinking to install it in the bedroom since it's tricky to get all...

    Intergas RF 36 benefits over HRE 36 or OV

    Thanks for the info on Logic. I hadn't realized they'd updated the design. It makes sense now about the RF chip now, so for evohome I'd ignore the internal RF (since it's older spec so incompatible) and need the OpenTherm/Modulation pack (RF bridge + controller) instead; or use one of the other...

    Intergas RF 36 benefits over HRE 36 or OV

    Thanks. In a post you mentioned the Intergas Canetis Superflow. I can't seem to find any reviews anywhere or detailed specs/dimensions, just press releases that make bold comparisons to 200l unvented cylinders. What's your impression of it? I assume it's floor-mounted and if it's fitted and...
