combi

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...

Hi all, I have a Trianco Eurostar combi 65. When the heating is on, I am unable to get hot water. If I set the thermostat to low temp to turn heating off I can hear the CH valve turn to hot water and it comes through. What’s the issue here? I am getting 230v on terminal 2 when the tap is...

Hi all, I have a Hive 2 as per the title, and I wanted to install it myself, but after researching, youtube, here, google. I can't find any info where the combi they have is anything like what I have, so now I am panicking I will mess it up. Could anyone possibly tell me the wiring I would...

Hi all. Firstly...I realise that I should really use the Hive Heating only, but as I got the Hive Heating and Hot water for £95, and having read other posts on here, I believe that if your boiler uses 230-240V then it will work. Boiler : Gloworm 38CXi combi...

Hi everyone Currently undergoing a loft conversion and my plumber has recommended to get an unvented cylinder installed, I like the idea of it but forgot to ask the plumber will this work with a combi boiler? Is it a simple job or will the boiler need changing? I've got a Baxi Duo Tec 33kw...

Hey :-) I wonder if anyone can offer some advice. My combi boiler isn't providing any hot water. The pressure is fine, the thermostat up. It's on, electricity is supplied and pilot lit it's only 3 years old. The gauge on the front is saying 20 degrees but doesn't go above this. Is there any...

Hi all - just after some advice. I am working away and leaving my UK house empty for a while. I have taken appropriate insurance cover for this, but one of the terms requires that either the heating be left on constant at 15 degrees C between Oct and April OR the main water stopcock is turned...

Just had the though the other day that, as hot water from combi boilers does not normally get exposed to any air and is always under pressure, is it technically safe to drink? :D Not saying it would taste nice or be a recommended thing to do though! Regards: Elliott.

I am currently connecting my UFH system to my combi boiler (Worcester Bosch 42CDI). I will T off from the existing radiator flow and put in a 2 port motorised zone valve on the rad flow, will I need a 2 port zone valve on the UFH circuit? I cant ever see a situation when my UFH will not be...

I have an estimate to supply & fit a new Baxi Duotec 33 combi boiler to replace my old conventional boiler. I wonder if someone could have a look and let me know if this sounds fair? Drain and remove old boiler Alter pipework to suit Remove HW Cylinder Upgrade gas supply to 22mmm pipe Supply...

I'm hoping someone can help with my issue please. Our 10 year old, regularly serviced, Glow Worm condensing combi boiler has recently started showing error F4 or F1 intermittently. Some days it works all day then another day I get an error code and have to turn the boiler off and back on again...

Hi everyone i realise this is an old thread but I have a similar issue....my combo goes on and off every few seconds....i have got 1.5 water pressure and I have already taken off the heat exchanger and cleaned it...when I set the boiler to just DHW nothing at all happens....when i set it...

Hi, I am installing a Nest onto a Worcester 25Si combi. It is to replace a Drayton SCR/ Digistat +3RF. I wanted to double check the wiring- ie. can I swap it like-for-like? Wiring, as shown in the pics (http://imgur.com/a/Ri7GW), is currently: Blue- N Brown- L Black- 1 (C) Grey- 3 (Call) Earth...

Hiya, I'm just getting ready for a bit of Sunday DIY but thought I would quickly check the wiring. This forum has been brilliant in getting me up to speed, but nothing wrong with a little confirmation from my peers! So... I think I've established that I can replace the Integral Timer in my...

First post on here, we have a betacom 30c boiler, recently the water isn't what it is should be, temperature wise.. The shower isn't as hot as it should be and goes hot and cold repeatedly, the separate bath tap is barely hot at its maximum and the same for the household taps. I've noticed as...
