boiler

My Keston C36 combi boiler is acting up - the water's getting way too hot. It's hitting around 90 degrees when in use. And then bounces back to 40s. The led indicator for DHW also turns ON/OFF while temperatures bounces. (PFA) Any ideas what might be causing this or how I can fix it? To add...

Hi all, I wanted to get your thoughts on a couple of options for a small flat in a mid-terraced house. We currently have an old electric immersion heater and were looking to update. We have no gas supply and currently the heater supplies hot water to three sets of taps (kitchen, bathroom sink...

I have ideal logic combi 30. I have put the hot water setting to maximum heat and reduced the water pressure to very low but I am still getting luke warm water. Central heating is working fine. some one told me that it could be heat exchanger plate. I don't know much about these. any help would...

Hi, I had a new Ideal Vogue boiler installed a couple of days ago, when doing final testing the boiler water temperature wouldn’t go above 45°, the engineer said I needed to register a warranty claim. I’ve paid for his time and parts and the hive but have withheld the payment for the boiler...

Hi all I noticed water dripping from the bottom of my Vaillant combi boiler and found the source to be the base of the flue where it connects to the boiler (as in the photo below). I've sent pictures to the boiler installer but he's ghosting me. Is this something I can fix? Tighten up the...

Hi, not sure if this is the right forum but I’ve just moved into a rented flat and we only seem to get hot water if we put on the boost for an hour, I have attached pictures of the boiler and just wanted to check that the hot tap was actually turned on and all the valves and things are on the...

Hi everyone, I've been experiencing some constant air bubbling noise on the top floor of our house. I've done some investigating and I think I know what's happening but I'm not expert so I figured it would be best to check with people in the know. I've tried to map out the system so here goes...

Hi all, My boiler is being replaced later this week. The old one was just plugged into a single switched socket which is obviously not ideal. I would like to create a usable plug, can I leave the switched socket and just create a fused spur off of that socket for the boiler? Do I need to use...

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
