combi boiler

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...

Hi, I already know that the ideal solution is not a combi boiler for this amount of bathrooms and that a separate hot water tank would be much better. That being said, I just want to know whether what I want to do will work. I have a Worcester Bosch greenstar 37cdi in the cellar and want to...

Hi, I have a Logic 24 Combi boiler. I have started having issues with the heating a couple of days ago when I realised the CH was not heating the radiators as much as it used to. I thought this may have been down to the pressure and tried to increase it slightly because it was on 1 bar and im...

I used to hear years ago that the UK and Ireland used to have 'seperate' hot and cold taps at the sink for a valid good reason , that it was by law (water laws) so that the water mains (cold) was seperate from the (hot water system) coming from the storage tank up in the loft. citing that the...

i have just moved into a new house in need of renovation. I removed a radiator yesterday and represurised the system afterwards. I woke up this morning to find the pressure dial at over 3.5 and the pressure release pipe outside dripping. I shut the water off and the boiler down and bled a...

Hi, I am a new home owner and admittedly very naive when it comes to things 'home' related! We have a Glow worm Ultracom2 35CXI combo boiler in the kitchen, and a manual twisty thermostat in the hallway. The boiler has 3 settings attached to the 'clock' where we could potentially adjust the...

I have a 3rd gen Nest thermostat that connects to my Vaillant ecoTEC pure 825 combination boiler. I’m having an issue that I have no hot water unless the radiators/heating is on. I have to keep setting my thermostat to higher than room temperature so that I can get hot water from the tap. I...

Hi all, I was hoping someone could just confirm that I have the right wiring setup to let me install a Drayton LP711. My boiler is a combi Vokera Linea 28HE. It currently does not have a time clock. To turn the heating on I select Winter in the mode selector. Hot water is on demand always on...

We just changed to a combi boiler a couple of months ago. I am finding that we have to run the hot water for up to thirty seconds before it gets hot. Sometimes it runs hot then cold then hot again. It's a brand new boiler. Is this typical of combi boilers (I have never used one before)?

Hi all, I am sure this is a much asked question so apologies if this is tiresome but I am really looking for some clarification on what is the best thing to do. I'll furnish you with as many details as possible. We've just moved into a new 3 bed semi, 1 bathroom detached house. There will be...
