heating

Hi all, I have a few of these Heatwell Aube thermostats in a new property, for underfloor heating. None of them seem to be actually controlling the heating in any way. Its just not firing at all. I've had them checked by an electrician and he's confirmed that there is power, which makes sense...

Hi just after some advice or if there is anything I can do before calling an engineer out. We have been in our home 2 years and the boiler is about 10 years old baxi duo tec 33 boiler I believe and never had an issue. We are having a problem now where as when the heating is on its perfectly...

Hello, we have the centaurplus c27 and it currently has no power. I am trying to establish if the problem is the central heating programme or the power supply. I have removed the until from the wall and replaced the battery. Does anyone know if the unit needs to be back on the back plate in...

Hi All Have run into an issue with heating at not the best time of the year. A few nights ago at 2am, a loud grinding/buzzing type sound was coming from the cabinet where the water tank, central heating pump and motorised valve etc are located. This noise eventually went away however the next...

Hi, I'm doing some decorating and need to take a radiator off the wall. I've done this a few times before however I've never seen a lockshield value like this one before where the spindle is completely round. Does anyone have any idea how to tackle this? Thanks in advance

Hello, Recently moved to a new rental place. The Vaillant EcoTec Pro 24 boiler was empty (I think for quite a while), refilled it via the loop to 1.5 bar & bled the radiators to remove any air. One of the valves (the smaller handle) in the filling loops leaks very slightly but I don't think...

Hi all, I understand that a CH system requires that at least one radiator have no TRV to prevent the user from closing all valves, and overheating the system, but I have also read on this forum that the radiator lacking a TRV is typically placed near the thermostat...

Hoping to solicit opinions before venturing into this project. The motivation is simple - shower/kitchen pressure (mind this is bungalow with 1.2m head ove r shower). I have been toying with the idea of connecting PHE to cylinder directly with pump and bunch of necessary components. But this...

hi Guys, I'm building an outbuilding for recreational purposes which includes a separate shed/garage.... I'm thinking of installing the new boiler in here as its easier to get the gas supply pipe here. I want to be able to control the central heating from inside the main outbuilding... like...

22mm tubes going through a solid 9" brick wall. 30mm holes drilled- strapped a spirit level to the drill & a square to the wall so they're straight and level for a change. Question- is that 4mm gap going to give me annoying rattles and creaks when thermal expansion kicks in (the 2 tubes are feed...

Hi, So for the past week we've been hearing this loud constant clicking/motor-like noise throughout the house, and I've managed to track down the cause of said noise. It's a white box inside one of our un-used storage cupboards that says it's a Drayton Zone Valve ZA5 Actuator. The device...
