combi

Hi all, I'm hoping someone can help identify the wires under the combi boiler. There was once hive installed however the previous owner has taken the reciever and install a standard danfoss thermostat. This is how it has been left. 15543993042235156073894454745445 by Matt Bezant posted 4 Apr...

Context is problems with shower. Starts warm, then goes cold and repeats. Have also noticed hot top also does this. I think the HW flow rate is too low. I thought at first maybe just crappy mains pressure, but noticed that hot water flow rate much lower than cold and so maybe boiler heat...

Hi all, I am working on a potterton heat max 28HE that has no hot water (hot tap runs cold but boiler fires up when the hot tap is on and hot water is sent to the valve) this boiler seems to be identical to the baxi deo tech? I have looked over many threads and had a convocation with a guy on...

I need some help! I have recently had a small extension to our 3 bed semi and with the work they have moved our boiler from the kitchen to the loft and as the water pressure upstairs was too low have installed a megaflop as well. I connected our smart metre earlier in the week and we are...

Hi Can anyone help me with how to wire a hive dual channel receiver to a Baxi Platinum? I know it should be a single channel receiver but is it still possible!? See attached wiring diagram for the boiler and hive Thanks

Recently had a new Greenstar 30i installed, a TF1 compact was added to the system in a most inconvenient place. We did tell the installer not to put it there (because a shower is to go in that cupboard), but alas they 'forgot'. So I have since drained the system and removed the filter...

The existing 3+E cable from the old Honeywell stat should be handy, even though I binned the stat itself. I think that stat fig. 5 and Riva fig. 6.15 are the relevant guides here.. Stat Neutral N (blue wire) to neutral N in the mains power supply block Stat Live L (red wire) to external...

New to this, looking for some advice... Combi boiler radiators (7 in total, upstairs/downstairs house) were not heating up some not at all. System always topped up with "inhibiter". Hot water great. So - all radiators removed and flushed clean. (Some black water, to grey to clear) - pipework...

Anyone know what the reputation of this boiler is. Being offered this cheap. Need a simple reliable combi for 4 radiators.

Hello, I have a Worcester Heatslave 12/14 combi oil boiler which will not run. We ran out of oil back in April this year and due to the hot weather and finances have only just got round to getting the tank filled. On first starting the boiler it goes into lockout, to be expected with no oil...

Ok I am a beginner so may not get the terminology right so apologies in advance(part of the battle with DIY is know what questions to ask(the other part is know who to ask)) but from reading other posts I think I am in the right place. So hope you can help me as the Title suggest I have and...

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...

I'm just wondering how well a Main Eco Combi Boiler (30) can cope with being switched on and off over a short amount of time. I grew up with a very old Glo-Worm boiler. It was dead reliable but we only had hot water in the evenings -- it was never on-demand, so as a kid/teen I never expected to...

Hi, I have a valiant eco tech plus 824 that has an issue. When I run the hot water, it runs hot for a minute then goes cold. The burner cuts out and won’t cut back in. If I run the hot tap on half, I get constant hot water. My engineer came out and was confused, rang valiant tech support and...

Bought a house recently and I am renovating it at the moment. It has a gloworm 24cxi combi boiler with a british gas on/off clock and a separate wired thermostat, im looking to upgrade it to a wireless stat. Does anyone know if a honeywell DT9E like this will work with this boiler: The...

Hi All Thanks in advance for any help - I have a Potterton Performa 24 which is playing up. The boiler is not striking automatically when either a hot tap is turned on, or the thermostat calls for heat. However, once there is a call for heat from either circuit and the boiler is turned off and...

Hi. Looking for some advice please. I have installed a new pump in my boiler, I first added some cleaner, let it run for 3 days, drained the system, installed pump, added inhibitor and refilled / vented. (the filling loop is in the attic) All the radiators heat up fine and i have bled all...

Hi Everyone, I've been struggling with this for a week or so now and after reading a few similar posts, I thought I would see if anyone could give me a little bit more advice. I apologise in advance as there is a little bit of a backstory to this. In December our hot water started going...

In June, the boiler showed an F20 safety switch off temperature limiter, sign. We had the Vaillant engineer come out, who told us that the water pressure was the problem.We were also told the TRV4 on our radiators are not suitable for our boiler. Something about a bypass. The heat needs to go...

Hi everyone looking for some assistance please as new to the whole renovation side of things. We are having a brand new central heating system fitting into our new flat in January as currently we have no heating at all. The only available wall is a stud wall which we'll be pulling down and...
