boiler

I have have a Vailant EcoTec Plus 937 boiler that is about 10 years old. During it's first few years, I had the VRC700f control with the wireless outdoor temperature sensor, that modulates the flow temperature based on the outside temperature. Unfortunately the outside weather temperature...

Hi, First of all apologies for having zero knowledge about any of this… But our energy bill was through the roof this month. Both these switches by the main boiler in cupboard were on. Then there’s this other one in the kitchen. I just need some understanding of how this set up operates...

Firebird boiler isn't firing so I assume I need to bleed it, but I'm not sure where the valve is. I keep seeing different things online that say I should loosen the valve where the Allen key is, or the lower hexagonal nut. Which is it?

We're having issues with the pressure on our Potterton Performa 24 boiler, it currently stands at zero. When the water is turned on it goes up to 0.2 absolute max. We're having issues getting hot water in our bathroom because of this. I'm attaching a picture of our pipes - I've marked the two...

Hi there I hope somebody can be of help. My Baxi boiler keeps blowing the 2 amp fuse. We went away for a couple of days and turned the heating to zero on the thermostat. I’ve come home and noticed a leak at the foot of one of the radiators and no heating. I’ve checked and the pressure had...

My Vailliant boiler (EcoTEC plus 937) which has a nest thermostat attached id not turning off the central heating!? We have turned off the Nest thermostat but the boiler continues to heat the radiators?

I’m trying to connect a hive single channel wireless thermostat. I’m having a few issues on trying to get it to work with my boiler and how to wire it etc. any help would be great.

I am the proud owner of an Ideal Icos HE15 that is 17 years old and somehow still functioning. I know that this boiler cannot modulate down very well, but I have got it working reasonably well and have spent a decent amount of time getting the pump speed sorted & balancing the heating system...

Hi All, Our Ideal icos he24 boiler display constantly shows 'c' and the reset does not work. It heats up the water and central heating. But makes loud banging sounds when the CH demand is turning off. Then shows HA over heat error code. After few minutes goes back to 'c' and repeats. I think if...

We've just had a new combi installed - a budget version Worcester Bosch Greenstar 1000 30kW. This replaced an old Baxi 105E 31kW that was falling apart. The WB unit is a nice boiler overall - the DHW arrives almost instantly - but I am disappointed to find it doesn't report the return...

Hi, I’m trying to top up the pressure but can’t work out how I’d go about connecting a filling loop because the valves are weirdly shaped and not what I’m used to. Any help appreciated!

Hi Is it possible for a DIYer to replace the flexi hose leading to the EV on a grant vort pro boiler? I tried to reenergise the EV but it won't let any air in. The hose does look a bit twisted and knackered. What would I need to turn off and release etc.? Thanks

Hello I have no pressure in my boiler and know I need to open the valves of the filling loop to pressurise the system but I have no valves on it and it’s not an easy unscrew system either. Turning the valves to the top of the copper pipes does nothing either

Hi all, Here is my setup.... Ideal Classic FF250 Brand new Gledhill 250L unvented cylinder and associated pump, zone valves etc (installed 2 weeks ago) Nest Gen 3 Thermostat (installed 2 weeks ago) All radiators have been bled As mentioned above I had a new HW cylinder and Nest programmer...

I'm having ongoing issues with my boiler heating water... I have an Open Vented system with the Cold Water Tank and F&E Tank in the loft, the Hot Water cylinder in the Airing Cupboard and a floor standing Potterton Promax FSB 30 HE Boiler in the Kitchen. The boiler is set to come on for...

I have a Potterton Gold Combi 28 HE on a brand new system following full renovation. However I am unable to get a consistant flow of hot water to any outlet. The temperature holds as hot for around a minute before fluctuating between luke warm and warm. Boiler has previously been sat in dry...

Hi all, Hoping someone will be able to help me please. I have a Potterton ProMax Combi 28 HE Plus, and recently the hot water pressure seems to have dropped, I can get hot water on my taps but only when the demand is for hot water only, as soon as you mix it with cold water the hot water light...

I recently installed a new radiator in the upstairs bathroom to replace a beastly radiator. During the installation process, I drained and filled the system three or four times during the installation process. (The water color was typically darker but flowed.) The new radiator is working great...

I got a brand new Worcester Bosch Greenstar 27Ri gas boiler installed in May and haven’t had any issues with it actually working, except since we started using it regularly we’ve noticed it seems to make a loud noise when igniting (I wouldn’t say like a bang but more like just a loud vibration)...

Hi All, Having a couple of issues with the central heating which I want to clear up before the temperatures drop. I run the CH via a thermostat. It’s set for 18.5 degrees and in the day it runs absolutely fine, if it drops below, the flame symbol comes on on the thermostat and the boiler fires...
