boiler

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...

Hi, I've just changed from a EPH thermostat system to Hive, just wondering if anyone could help in matching the wires up for me, are they installed correctly? I've attached 2 photos showing the change I've done between them, thanks

So a couple of weeks ago we noticed the boiler making this noise (see vid), its much louder than we've known it to be, and there seems to be condensation or steam coming out of the hole in the top. Strange thing is that it only makes this noise if we run the bath, the sink taps or heating do...

I have inherited a house with a Flexicom 30hx boiler (heat only). With a cold house and plenty of demand, it operates rather strangely, where it will run at full tilt for 30 seconds or so (up to ~80c flow) but then you can hear it stop, and it cools down for a long while, before then having a...

Hi, I had a Vaillant ecofit pure 830 combi installed at the beginning of the year. Flushed and new protection kit fitted, etc. Came back from a 2 week holiday and now I'm getting a horrible loud pulsing noise that vibrates through the house. Happens with both ch and hw. Have attached a short vid...

So we took a radiator off the wall on the weekend in order to paint the wall. Turned off TRV and lockshield valve, drained the water from the radiator etc. Capped off the TRV but it appears that it still kept leaking through the cap (I guess the valve doesn't close properly, never seen that...

Hi Sorry for another expansion vessel question but I can find this asked previously Had my boiler service yesterday and the engineer said it is full of water and it needs to be drained. He didn't mention anything about having popped. I pressed the valve and zero water came out. I replaced the...

Hi all, Having some issues with Nest or boiler not sure what one is causing the issue. It’s a Biasi advanced 25c boiler with Nest 3rd gen thermostat. Basically been working fine for the 4 years it’s been installed, went to test it out a few weeks ago and it wouldn’t fire up in manual mode but...

Hello, I moved into a new flat and have an electric Strom boiler for hot water and heating. The hot water is fine, but when i switch the heating on the temperature goes up and up and when it reaches 50 it switches the whole system off. the overflow light also goes on. I usually get a few...
