combi boiler

Hoping for some advice. I need to remove the plate heat exchanger on my combi boiler to clean it. I've switched off the power to the boiler, closed off the valves and drained it using a hose and checked the pressure is on 0. However, when I start unscrewing the screws that hold it in place I am...

Hi, I have a Worcester Bosch Greenstar 35CDi combi boiler running on LPG. This works very well providing both hot water and central heating. I have recently installed a PV solar/battery system and expect to have more electrical power than I need for about 8 months of the year. I am looking at...

Hi, We have just had a grant vortex oil combi boiler installed and we have two options to heat our hot water; we can have the water on continuously which will keep the very small water reserve in the boiler at a certain temperature. Or we can have the hot water off and then just boost it when...

Hi Community, I hope you can help with this one..? My Ideal Isar HE24 recently failed. Hot water, but no heating. Home insurance sent a man - he said the LP711 timeswitch was at fault and did a temporary fix as an override. So now, when the boiler is switched on the central heating is on...

I was wondering if anyone had a suggestion or idea that may help. We have a Baxi Duo Tec 33 erp, which is about 5 years old, and working absolutely fine until last week. The central heating is working perfectly, however, when you turn the hot water on, after a few minutes (long enough to fill a...

I got the nest to work great with the heating of the house (gas boiler), but the hot water for the house stopped. So no idea what happened. This made me think I should connect 4 to 10 on the main wire box as that is how the nest can talk to the water tank. Is this wrong? 20211106_162911 by...

My mother-in-laws Glow-worm combi has starting making an awful banging noise. Apparently it started about 5 years ago and successive yearly services by a couple of heating engineers has never come up with a fix. One suggested a pipework problem somewhere. In the last year it has become more...

Hi All, I am looking to change my Boiler (system) to a Combi Boiler. I have received a few different quotes and I don't want to take the water directly from the mains. I have no pressure in my showers as the tank is in the attic and the bathrooms are in the first floor. So I am between 2...

Hi, I had a new Grant Vortex Combi 26 boiler installed 1 year ago. I also bought a Hive thermostat and wired it in myself. Having never owned a combi boiler before I thought all was well. Central heating came on when I wanted and I had hot water. Then I realised that although I could get hot...

Hello I have installed the Drayton wiser hub r and have connected it to the dual digital thermostats. Whenever I increase the temp on the thermostats the little flame appears, and the LED for heating on the hub r lights up but the central heating on the boiler does not come on. We do not have a...

Hi all, I'm looking to reorganise some copper pipework to where a combi boiler will be installed. Planning to chase out a section of a conrete floor for the pipework and using fixing band instead of clips too so the chase doesn't have to be too wide or deep. My question is can all these pipes...
