    Upstairs radiator not bleeding

    Hi there, I've got a tricky problem so hoping someone out there might be able to help me. At the moment our upstairs radiator closest to the boiler isn't heating up properly at the top. I tried bleeding the radiator thinking it was trapped air, but when I open the valve fully, no air comes...

    Vokera Unica 28HE

    I'm trying to find out about the above boiler as I can't find much in the way of independent reviews on the internet. The MiL has one fitted in her newly-purchased house. She phoned me the night after she'd move in to say there was no hot water. I checked the pressure gauge which was at zero...

    Boiler making a hissing noise and pressure going up rapidly.

    Hi, I have an issue with my boiler which consists of it making a hissing noise and pressure meter going up when the central heating is on. I haven't tested what happens when the pressure is extremely high as I turn it off before it goes above 3 bars. The central heating is not working but hot...

    Wireless Mains Switch on CH Timer

    Hi, I recently bought a couple of WiFi mains switch boxes which just connect live and neutral from the input across to output when operated. One will be used to control our porch light and I would like to control the house CH with the other one, if that's possible. A bit of a Hive-on-the-cheap...

    Setting 3rd on/off time

    Hi all, This seems like a friendly forum so I thought I'd give it a go. I've just had my gas boiler replaced and had a Siemens RWB 1007 timer installed as part of the installation which works fine except that I can't set a third on/off time. I've called Siemens, but their recorded message told...

    Baxi Duo Tec HE 40 heating issue

    The problem I'm having is that occasionally, when the heating is switched on, the green 'radiator/heating' light comes on on the boiler, but not the amber 'flame' light. While the boiler is on this state, radiators don't get warm. If I turn the boiler off and back on, the heating kicks in as...

    Underfloor heating controls - a conundrum

    Almost a year ago I was trying to resolve a few issues with our underfloor - see orignal thread in plumbing here: https://www.diynot.com/diy/threads/underfloor-heating-a-couple-of-issues.493454/ The meachancal side is fairly under control (!) now nut the control side - electrically, is still...

    Heat going off too soon - please help!

    Hi all, I spent the past few days trawling these forums to find the answer with no luck so hoping someone can help. Just got a new gas combi system, so all new boiler, rads, pipes etc. The thermostat and an 'always on' radiator are in the hall. This rad is reaching the stat temp so quickly...

    Heating will not switch off

    I have a Main Combi Eco 25 boiler and a Salus RT501RD(TX) room timer. I've just had the boiler serviced and as part of that service had a new diverter valve and actuator motor put on. The reason for this being that the valve was stuck in the mid-position. I now have a new problem. Despite what...

    Hive Help?...

    Hi there, Another Hive post, I know, I'm sorry. We've recently had a Ideal Logic + 35 Combi boiler installed. The plumber knew we were going to install Hive so didn't install a thermostat or any kind of timer, just a spur socket. I'm trying to determine which wires go where... Can anyone help...

    Combined wet and electric underfloor heating in wet room

    Hi All, What would be the correct setup for combining wet (primary) and electric (secondary - for summer use) underfloor heating. We are installing a wet room on a concrete slab and will be insulation about this and then Screeding. The screed will contain wet underfloor heating pipes, the...

    Poorly installed boiler

    We had an extension done about 11 years ago and have just found out that the boiler was wrongly installed on the boundary wall. the vent slightly overhangs into neighbour s property which is about 1metre away from their wall and the steam blows around near their door. The neighbours after all...

    Boiler Diverter Valve

    When I use the hot water on my Main Combi Eco 25, all the radiators heat up. The longer the request for hot water is there, the hotter they get. The boiler isn't old (late 2012). It was fitted very well by someone local considered very experienced (43 years) in what they do and is a very tidy...

    Boiler switched off and on

    I'm just wondering how well a Main Eco Combi Boiler (30) can cope with being switched on and off over a short amount of time. I grew up with a very old Glo-Worm boiler. It was dead reliable but we only had hot water in the evenings -- it was never on-demand, so as a kid/teen I never expected to...

    Replace a Towerstat RS thermostat with a Salus 310RF

    Hi, first post, so I hope I have the correct forum I am planning to replace my Towerstat RS thermostat which is in a bad location in my hallway with a Salus 310RF. This is in order to allow us to have the thermostat in the living room rather than the hallway. The Towerstat uses two only wires...

    Looking for GEC Nightstor or GEC Compact

    Hi, I'm trying to get hold of a second hand GEC Nightstor or GEC Compact unit for a project. (It doesn't matter too much which one it is) If you have one that you're trying to get rid of or know someone that does, please let me know. Preferably in the South East of the UK so it's easier for me...

    Running out of Ideas

    All radiators are cold, pump is ok, boiler is firing, hot water works, bi directional valve working. Pipes leading from the pump are good and hot but absolutely nothing at the radiators. Struggling as to what to do next

    Can’t get radiators to turn off

    Hi, As it’s now summer I’ve wanted to switch off my heating entirely. It’s a modern system in a new build house. I’ve got a control panel (that now shows heating as off, hot water still on fine). I noticed that some of my radiators were still hot - even though on their controls I had turned...

    New magnetic filter AND powerflush needed, or just new filter?

    Hey everyone, We had a new combi boiler (Ideal Logic Combi 35) installed with a magnetic filter (Ferrox TF1) about 5 years ago. At the time the system was apparently powerflushed by the installer (it was definitely drained, as i guess it needs to be, but the plumber was not very...
