Another hive thread! Hi all wanting to replace my current digital timer/thermostat with a hive V2. I have a Worcester Bosch Green Star 30si Combi boiler. My current setup is as shown in the attached image. The thermostat is in my landing and boiler is in the garage. The boiler connects to a...

I posted this question in September: https://www.diynot.com/diy/threads/diverter-valve.509393/ The answerer talked about diverter valves and cartridges. I have a few questions: 1) What the difference is between a diverter valve and a cartridge? 2) Why could the cartridge fail independently of...

Hi. I have recently had a External Worcester Greenstar Heatslave II 18/25 External Combination Boiler Oil ErP installed which is controlled by a salus it 500BM I understand at the time, there had been a mix up and the incorrect Salus was installed and it should have been the salus it 500 and i...

Hi I am new to this site but wanted to ask a question about a fault which has arisen on my Ravenheat Boiler. In the last day it has stopped delivering hot water either to the taps or the CH. The pilot remains lit, the boiler fires up and I can hear the fan working. Occasionally I get about a...

System is gas central heating via a pressurised combi boiler system. The combi is a Alpha C27. Often the user is operating only two radiators. The balancing radiator and one other. Operating 2 out of 7 rads in total. Recently this combi has been de-pressurising once or twice a day soon after...

Good afternoon, New to this place as a Google search finds me a few threads on the Main 30HE combi, so thought I'd try my luck.. New house with a Main 30HE Combi, 12 year old. Seller was adamant it still worked, much to my dismay things went wrong from there. Been here since end of May and we...

Go on then slate them lol, I am aware of the kw price difference. So I live in a bungalow well of the grid, gas mains never gonna be an option unfortunately. Bought the house three years ago. Installed a biomass system, burn logs get hot water and it heats the rads. So we are building an...

tl;dr: Why install RF36 instead of HRE36 or Ideal Logic+ 35? How does weather comp/new thermostat differ to boiler's internal modulation? Is a non-pumped gravity shower acceptable (better than an 8kw electric) upstairs even with very old slow recovery HWC, or just go combi at 13lpm in small...

Hello, I mistakenly purchased a Hive Dual Channel Receiver from my Worcester-Bosch Greenstar 30Si Combi Boiler. From reading other posts, I believe it is possible to still make this work, but need some assistance please. The current receiver is a Honeywell R6660D. I have cables currently...

Hey everyone, We had a new combi boiler (Ideal Logic Combi 35) installed with a magnetic filter (Ferrox TF1) about 5 years ago. At the time the system was apparently powerflushed by the installer (it was definitely drained, as i guess it needs to be, but the plumber was not very...

Installed a Beok WiFi product to the undefloor heating and thought I should get another WiFi-enabled controller for the combi boiler! :mrgreen: Having both units on one 'app' would make it easy for the OH. ;) Looking at the details the Beok has the following: And my combi has: What connects...

We have a Baxi 105e Instant and have just had a new mixer shower fitted. The only thing we have noticed is that the pressure on this seems low. Is there anything that can be done to improve this? I don’t think pumps are compatible with combis. I think the pressure is down slightly following...

I have a vokera HE combi boiler. It heats the flat and provides hot water. There is sufficient hot water for the sink, basin and shower but when I run a bath the water is hot to start with but then cools down. I have had the heat exchange replaced. There are 4 water pipes running into the...

Hi friends I m Zmicer. I am plumber heating from Minsk Belarus. let me show you my last project. I wold like to get your opinion. One my customer has a Сombi boiler in his house, but the Combi boiler does not give enough hot water when he needs a bathroom. I have a plan "B" for him to solve...

Hi everyone. sorry for long post. I have a bit of a strange issue with my boiler. Had my boiler installed in jan 2012 and has always been running very well. Lately I Had an issue with my boiler pressure going over 2 bar and then going down below 0.6 bar when system cools. I drained the boiler...

Hi I wonder if anyone could point me in the right direction for troubleshooting? I have a 12 year old worcester heatslave 12/14 combi that keeps locking out after 5 minuets, after leaving it for another 5 minuets if i hit the lockout reset it will run again for a while then go back into lockout...

Hi, I have a property with 2x Mixer Showers being fed by a worcester junior combi boiler, as you can guess this means the showers don't operate correctly when they're both turned on at the same time. I'm in the process of upgrading the system and would like would advise from those in the trade...

I have benefitted a lot from posts on this forum and all the helpful advice from professional fitters - so just wanted to post a solution to a problem I fixed in case anyone else is experiencing it. We had a problem with our Intergas Combi boiler (a brilliant boiler BTW). The pressure level...

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...

The situation: Having recently found a leak in a micro-bore pipe, thanks to a plasterboard screw going right through it. I decided to fully drain the system during the repair and fill with a system cleaner to run for a few days and then drain and refill with inhibitor. The initial problem: Upon...
