central heating

I've just had a WB greenstar 4000 installed, but cannot work out how you turn the heating off. It seems you can only turn it down to the lowest.. 30 degrees.. But there always seems to be a gentle humbing noise from the thing. My previous boiler an ideal logic c30 would just be silent when...

Hi all, I'm really stuck with this one. I have with our solid fuel back boiler system and my novice understanding is pretty much out of ideas. We've recently moved into a new place that has the hot water and central heating powered by a stove in the lounge though a back boiler system. We...

Hi, I've got 11 radiators over 3 floors. Those at the top struggle to get warm enough given the boiler is located on the ground floor, and will continue to pump water to the ground floor radiators even when they're hot enough. The simple solution would to install Wiser thermostat valves (we have...

Hi all, I've had an issue plaguing the CH systems since we bought the house. It's not causing any functional issues (yet) but is affecting quality of life. We bought the house 2 years ago, it's a 50s build, and has a Baxi Bermuda back boiler. We changed out the rads as we were doing some...

Hi, I want to be able to turn off the “control radiator” and only heat my bedroom in the morning during the cold months. There is no TRV or manual valve on the control radiator . We are all trying to save energy with prices so high and set to get higher. I can see a potential 50% energy saving...

I have a three year old Worcester boiler and I have been told I need to have a system filter. There is a big discrepancy in price between the filter options. How do I evaluate what difference the options would make in practice? Any advice would be appreciated.

Hi, After some advice my wallstar boiler has packed up meaning we need to replace it with worthing that's efficient and cheap to run. House was build in the 30s and only has loft insulation and double glazing We are unsure if to stick with oil and upgrade to a newer external combi boiler...

Hi all, I'm trying to understand an unusual issue have noticed. I have an open CH/HW system with 3 zone pumps and a header tank in the attic. All points are working fine except for a towel radiator. At my towel radiator in an upstairs bathroom (highest rad in the system), when any of the 3 zone...

I have a Potterton Profile 80e driving CH and HW through a 3-port valve. On the HW side, there is an indirect cylinder with only a short circuit between boiler, pump, valve and cylinder. I have noticed that, when there is little heating demand and HW is not up to temperature, the boiler cycles...

Good morning all, I am wanting to replace my current old outdated thermostats with something more modern but have no idea what products would be suitable replacements as I have zero knowledge with in the field. I have ESWA ceiling heating, with individual room thermostat controls in each...

As of yesterday none of our radiators have been heating up. However, we still have hot water. We have an old conventional (ie not a combi) Potterton Promax 24/2 HE boiler on a vented system. The thermostat is not the issue since I switched the override on to turn on the CH but the boiler...

Hi, I am trying to renovate my recently widowed mum's house for her, and have noticed the boiler heats the house very quickly, but the temperature also drops quite quick. I have a combi boiler in my house, so I don't know much about their boiler and gravity fed radiators. In hind sight should...

We had a new CH combi boiler installed 4 months ago, corrosion inhibitor was added to the water and everything seemed to have been done correctly. I was away for about a month and noticed the boiler pressure was ever so slightly lower than when I left it. I went round all radiators checking for...

Hi everyone, I'm desperate for help. We tested positive for covid 2 days ago and on the same day our downstairs rads went off, we have a 20 month old baby so it's not ideal. I can't call a plumber obviously! Things I've already done: bled all rads, checked pressure, turned all rads off...

How many turns on this thread labelled here in pic that goes into rad (not sure what you call it)? Also can you get some chrome touch up paint or something as it has chipped off while tightening nuts before?

So iv got to add a mini one UFH zone to an existing property's heating system, i have already wired in all the easy parts ie. actuator, zone valve, stat etc. however i just need to hook it up to trigger the boiler. iv attached a few images to try and explain things better, the plumber told me...

So I have a lockshield with a drain off attached to it, I Used it to help drain out the system, but I noticed as I used it when sealed back up it dripped a bit. So clearly me opening it up kinda knackered it. Now I have taken it out and had a look, and the black seal is still inside the drain...

This video, he doesn't drain down the system fully, he just drains it down enough to get the pressure to zero and then works on the rads. Do any of you guys use this method, its the first time I've seen it used and does make sense, if the pressure is low when you take the valves off, you'll get...

So I fitted and tested the new radiator. Apparently only brass compression elbows are suitable with these nice black coated brass pipes I have. Previously copper and pushfit elbows were used (left and right sides respectively) which weren't suitable. The brass elbows are fitted nice and tight...

So I had the acova 3 column radiator from Screwfix fitted yesterday. But I believe it has been fitted the wrong side. Instructions manual clearly states: VERY IMPORTANT: PLEASE NOTE: WHEN CONNECTING THE PIPE- WORK TO THE RADIATOR, THE WATER MUST ENTER THE RADIATOR AT THE BOTTOM CORNER...
