combi boiler

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...

Have a Ideal Logic 30 (Combi Boiler) with "PCB Fault" on screen (photo below). No hot water for anything. Manual gives no indication. Photo of serial number below. Anyone ideas? I gather the "1304" means it was manufactured in 2013 on the 4th week of the year.

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...

OK, I last posted in here in 2009 with guidance given on a new system. https://www.diynot.com/diy/threads/thermal-store-heat-bank-or-two-combis.170502/ At the time I was running 2 combi's twinned to supply whole house. In the 2009 post I was looking for guidance into a replacement system as...

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, 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...

the boiler fully works but every few hours the hot water light will start flashing and the boiler sounds like it's working, but there is no hot water running I have to reset the boiler to stop it doing this Does anyone know what this is? Thanks

Hi, I have a Worcester Bosch Heatslave 12/14 Oil Boiler. The unit has controls on the front that control both the water timer / advance and the heating timer / advance. I bought a Hive system and have successfully connected to the heating side of the boiler. I am not sure how I connect the...

Hi all, We have a Remeha Avanta Plus 28c Combi boiler. It has been serviced regularly and is still working well, but the plastic casing has started vibrating intermittently when in operation. It's not a loud noise but enough to be irritating when we're in the kitchen - pressing on the case at...

So begins my sad saga. Like most of us, I like a problem and the satisfaction of solving it and felt capable of doing so as I have had some plumbing experience (Pre Corgi) and have, in fact fitted a complete system around 20 yrs ago (Tho my mate, Bill the Plumber did the final checks) Here...

Hi am looking to replace my alpha cb24 this month as it keeps loosing pressure and it's old non condensing pretty 2005. Don't want to repair it. We have a baby due soon. My thinking is will be using more gas / heating so better to have something efficient. We have a 3 Dbl bedroom semi with a...

Hi all, I'm looking to get a hive to wire up to my betacom 30c combi boiler with no existing thermostat. Looking at the manual it appears that I have two forms of connectivity. One being 24v and the other being 230v. I've had a quick look at the hive manual to make sense of what's required and...

Hi, Need some options on feed when changing from an electric shower we have to a thermostatic shower. Our change comes about due to a change in boiler to a combination and thus wanting a more powerful flow from the shower. Our electric shower is in a wet room with the cold water feed coming...

Exchanged the pressure relief value today but now when we put the heating on the pressure won't stop rising and boiler is shut down by safety switch. Pressure stays constant when heating off so have hot water but as soon as heating goes on it just shuts down. Any ideas please.

Hi Guys Bought new Tower RFNP wireless thermostat to replace old hard-wired one but have three wires coming from boiler and the thermostat receiver talks about needing 4 wires. What do I do? This is what the thermostat instructions say... For conventional heating installations, connections...
