heating

Hi all, I'm new in here. So I'm working on a tiny house for myself and currently designing the CV & warm water supply system. I'm an engineer myself, but CV, electrical and plumbing are not my core expertises, so I was trying to seek for a professional advice here in the Netherlands where I'm...

Help me please! Moved into this house last year, it hasn't been looked after at all. Gas combi boiler (Alpha InTec 25XE) has always just about worked. It's only ever given us constantly hot water if the tap or shower is turned on to a very low pressure. Even half pressure and it'll run hot for...

Our radiator in our living room is only luke warm at the bottom and boiling hot at the top. The pipe into the TRV valve is only slightly warm and the lockshield valve is boiling hot. We had the radiator refitted after some plastering around October last year. The radiator is the closest one to...

Hello, Wondering if anyone can help please. I have what I believe to be an S plan central heating system, consisting of: Worcester Greenstar 27Ri boiler Horstmann h37xl programmer British Gas RS1 room thermostat Danfoss zone valves x2 Honeywell wiring centre Telford stainless sealed hot water...

Hi guys Wondering if someone has an idea to my issue even my plumber doesn't know why. Firstly, the boiler is about 3 years old (moved into new house Sept 2019). The boiler is absolutely fine. I'm getting hot water to all taps and showers, so we can rule the boiler out. I have 2 central heating...

Hi, I'm trying to convert my current heating system to use the wiser thermostat and controller kit 1. Here is my current controller I have the indstry standard backplate underneath which is what I intend on replacing the above with. Here is the diagram The diagram is confusing me...

Hi, I’m hoping if someone can help me, I’m a DIY novice! On Friday morning we woke up and both the heating and water weren't working (apart from the kitchen tap cold). The temperature on Thursday night was -7, and it hasn’t got much warmer, up to about 0 degrees. I’m assuming I have a frozen...

Hi all, I'm living in a rental property and my old 1970s warm air boiler has broken. The landlord is happy to replace it with a new system and seems to not mind what direction we want to go in. With this in mind, I'm trying to decide whether a replacement warm air system would be better or if...

It is not the element as it does heat on ECO and 30min. It is still useable! I am guessing 1) programmer/timer or 2) the flexible cable/wiring harness, but I cannot find a decent complete wiring diagram. Service manuals available online do not seem to be designed for the fault-finding DIYer...

Our boiler began making a noise at the start of the year so we were meant to be getting a new boiler this year but due to shortages we’re not getting one until January. The noise stopped during the year as we weren’t hearing the house, but last night it started up again. We just want to know if...

Hi All I was hoping you might be able to help me with a situation. I have recently installed the Hive system which is the dual channel (hw&ch). Our system is a gravity feed Y-Plan system (so I believe). The issue we are currently having is when the central heating is turned on, the light on...

I'll preface this by saying I know that its not going to be possible to get an exact price without getting a plumber in to take a look... I've just bought a 1930s semi, in decent condition no real work needed on it right now. The only thing is the house only has 5 radiators including a towel...

Hi all, I am planning on doing a wet DIY underfloor heating install downstairs of my property. I have zero experience with the plumbing and electrics side of the install, I plan to get a pro in to hook everything up but want to ask a question to make sure I have not missed anything prior to...

To those boiler installers out there, if a customer asked you to install a boiler somewhere that you knew would block as aspect of the regular service, would you do it anyway or refuse? What would the regulating body do if a complaint was made to them on this?

Hi, I’m new so apologies if this has been asked/resolved before. I had an engineer install my Hive Heating System yesterday, however, when I try to control the heating from the app or thermostat the receiver clicks on but it does not fire up the boiler. All the lights etc area solid green...

we have a combi boiler with a timer that is always on. we then use a wireless thermostat around the house to control when the boiler fires up. if we don't want the heating on, we simply drop the temperature on the thermostat to a point lower than the current room temperature, which ensures the...

i've recently balanced my system and learned a bit about inlet/outlet flow, TRVs and lockshields, but something is still bugging me. assuming a system is well balanced, and you're using the TRVs on a towel rail, if you set the TRV to 1 (therefore limiting flow) does this mean that the top rung...

Hi I'm obtaining a few quotes from different local plumbers. Do I need an expansion tank for the heating if the hot water cylinder has internal expansion and does not require one ? I’m looking at having an Ideal Logic Max Heat only 24kw boiler fitted to replace my existing one and a Halo...

Hi All, I am doing a kitchen extension. 3m X 6m, and like to install wet ufh. need help to decide the best way to prepare my concrete subfloor for wet ufh. option 1: mot + sand blinding + dpm + kingspan + dpm+ concrete + ufh boards (18mm) + ufh pipes + screed + tiles option 2: mot + sand...

Hi, long story short my hive has been wired using a dual channel receiver on a viessmann combo boiler. Since removing the hub as I’m moving home, it only fires the boiler when I boost the hot water on the thermostat. Spoke to hive who said I should us the single channel receiver for the new...
