I'd like some advice on what I should connect to my new boiler please I'm getting a Vaillant EcoTec Plus 940 installed and I don't think my plumber would mind me saying that he's a great plumber and corgi engineer but he hates all that smart boll-ox. I currently have a Nest connected to the...

I have the 2023 release Vaillant Ecotec Plus 832 installed (touch screen display at front). It was installed with a Wolseley Centre wireless controller however the radiators were taking 50 minutes to 1 hour to come up to the target flow rate of 60 degrees and after much misdirection by Vaillant...

Hi, Only my 2nd post, but you were all so helpful with the first post I thought I'd have another go. I was talking previously about how I have a fairly new combi boiler (Vaillant Ecotec Plus 832) and also some solar PV and had the notion of fitting a HW cylinder as well. Since then, I've seen...

Hi All, Looking for some advice please! Not sure if this could be a DIY Home fix or if I need to call an engineer. I have a Vaillant Ecotec Plus 418, which appears fine on the hot water side and is able to maintain temperature however when I call for heating, initially it seems to go for a...

Hi All I have had a search through previous posts and google, but everything I find seems to get me more confused. I have just had a new Vaillant boiler fitted, an ecoTEC plus 838 combi. It is just the boiler at present, operated by the controls on the front only. My plumber is offering to...

I’ll try to keep this as short as possible! Basically the timer has died on my Ecotec plus 831 combi and rather than just replace it with similar I was thinking now maybe the time to go smart and get something that can help my heating system run more economically as we’re off grid so run off...

My Vaillant ecoTEC plus 618 display is always illuminated - previously it would go dark until I turned one of the temperature setting knobs. Not only that but now the temperature shown is flickering irregularly around the preset temperature (70°) and also flashing back to the outgoing...

Hi All, I have got question on installation Nest Heat link to boiler. I have got Vaillant Ecotec Pro28. I currently have Honeywell thermostat and receiver (wiring) has been shown on picture attached. Should I do exactly the same as on the picture above ie: N to N L to L With yellow/ green cable...

Hi All, I'm looking to wire up our Ecotec 937 plus with Opentherm and Evohome. So far I can source the VR33 module and have located the X31 interface on the PCB where this should be plugged in. Unfortunately it appears to have another connection already plugged into this serving the shift load...

Hi. Got a Vaillant ecoTEC pro 28 combi boiler which is about 10 years old. I had a plumber come today as our boiler continually turns off with a F.62 warning and red light, have to press the flame button with a cross on it to reset and get hot water back. The pressure also continually rises to...

Hi I have a cpl of question, but I'm also posting as this might help others trying to get Drayton Wiser to work properly with Vaillant (or other boilers). Setup: ecotec plus 418, S plan, installing Drayton Wiser smart controls (currently 3 rad valves). Problem: the boiler is short-cycling...

Hi all, Just wandering is the nest compatible with the vaillant ecotec 838 plus combi boiler? And if so, does anyone have an appropriate link with how the wiring should be undertaken. The boiler is a brand new install with no current thermostat installed. Any help and advice would be largely...

Firstly, I'm not going to attempt to do any rewiring my self - but I do have a Gas Safe plumber on the job currently (waiting for an internal pipe that is leaking a bit), and I want to get informed on our situation so when he comes back we can get it sorted asap. I have a Y plan heating setup...

Just sent this to their customer service dept: -- I've just had the unfortunate experience of becoming one of your service plan customers, and it's been all bad so far. Zero points for customer service. What happened? The inlet pipe on the heat exchanger of my Vaillant ecoTEC plus 624 boiler...
