heating

Hi there, Another set of questions that someone will hopefully answer. I’m planning a domestic ground floor renovation incorporating wet UFH. The build up consists of: Damp proof membrane over existing concrete floor 20mm Low profile boards with 16mm pipes - either EPS or XPS 300 kPa - no foil...

Hi, Looking for some help please!! We have a Worchester Bosch 8000 Life (50kw) boiler. I am running it along side Tado - where i have Smart TRVs 3/4 of my radiators. My house is fairly big - 5 bedrooms and roughly 300m2. Its very cold outside at the moment, approx -1 and my gas heating bills...

I have a breezeblock outbuilding, two sides built against the wall of my house (not insulated), one side built against concrete steps up to my garden (newly waterproofed with DPM, drip drain, insulation and ply-lined), and one side (not insulated) with door (single glazed) and window (double...

I probably need a professional for this, but can anyone help me narrow it down, so I don't get completely fleeced please! From what I can gather from searching, it looks like it could be sludge and/or pump failure. With the combi set to 65C rad flow temp, I see it cycle from about 50C to 75C...

Hello! Wondering if someone can help, Google doesn’t seem to understand my question… I have 2 upstairs radiators (combi boiler) on smart TRV’s which don’t get hot when valves are open. The TRV’s work fine, and I can hear them call for the boiler correctly but the rad’s stay cold. HOWEVER…...

Hi all, looking for some advice. Trying to change over the existing digistate scr to hive. Advice on which wires to move over would be appreciated This is for a duel system.

I recently moved into a house that has a Valiant ecotec plus 415 boiler, gravity fed with an hot water tank. To get the boiler to heat the hot water I have to manually set the heating flow temperature (which is the central heating setting) on the boiler itself. The controller we have downstairs...

Hi all, My system is the older kind with a hot water tank (not the hot water heated on demand type). Hot water is working okay. All the heaters in the house have suddenly stopped working. I put my hand on the inlet pipe to all of the heaters and none of them feel warm. The main thermostat...

Hi, I hired a company to supply and install an MVHR system in my bungalow, and to say I have significant concerns about their performance is an understatement! Some of it I know enough about and am picking up with them (e.g. the 'fixes' to holes they've made), but I'm concerned about the...

trying to get rid of an air lock in our boiler after emptying central heating system and looked in the airing cupboard at this setup . the alarming thing I found was going up into loft at the F&E tank expecting to see the cold feed being a 22mm ... but its only (equivalent) of 15mm - I say...

Hi All! I’ve been researching the installation of hive in place of our current system which is a Honeywell ST9400c. Our set up is boiler and water cylinder, with two thermostats controlling both upstairs and downstairs. I’ve pretty much got my head around the process but quickly losing...

I have two radiators that I need to install in slightly different locations to the originals. The cheapest quote I have had is £1,150 with me supplying the rads myself, which is unaffordable so I want to explore doing the job myself. The flow and return are in concrete screed. I have excavated...

Hi, Looking for some advice, an installer came to give me a quote for solar panels and he brought up the subject of a heat pump too. I live in Scotland and apparently the grants only apply if you get both together, which is fine as my boiler is getting old anyway. He said something about the...

This thing in the photo started making a loud buzzing noise - is this an easy fix? …what is it? Video in the link… https://share.icloud.com/photos/09eJwW9Dp5Ih9yc7LiqOPGmxg

Hi all, I'm looking for some advice please? I'm currently building a 2 storey house, and the plastering was finished approximately 4 weeks ago. However, due to the cold weather (it's barely gone above 0°c in the daytime and as low as -12°c during the night, for the past 2-3 weeks) it still...

Hi, I'm seeking some advice regarding my Valliant Eco Tech 28 boiler. It recently started leaking. Upon investigation, I noticed water coming from the boiler pump. There's a grey knob on top of the pump with a small hole. When the heating is on, water pours out of this hole. I've adjusted the...

Hi All! My first post here.. I need some help from someone who really understands central heating systems, pipes and radiators. New boiler installed My 20 year old Ideal Mini boiler finally failed in December with no hot water and it was leaking all over the floor. It turned out it would be...

Hello, can anyone help me please? (apologies for the layman's terms in places, but I hope you can understand what I mean). We had a new radiator installed today by a reputable plumber, as the old one had slush and would no longer heat up. I'm told the existing pipework was also flushed out. It's...

So where to start I moved into a property that had single pane radiators earlier this September. We had some work done on the house and whilst the water was off we had the downstairs radiators upgraded to more efficient radiators. The upstairs remain the same on 15mm pipes and downstairs...

Hello, we have a radiator in our living room and would like to add a second. The photo shows the piping going into and coming out of the radiator. From feeling the order that the pipes heat up I think I’ve figured out the direction of flow which I’ve marked with red arrows. Would this pipe...
