Hi, i was wondering if anyone can help me out with this. Recently got called to a breakdown on a Boulter Camray 3 with a Riello G5X burner. The boiler would purge, spark, and for a split second ignite only for the flame to fail. It doesn’t go into lockout, the fan continues to spin and it...

Hello, We had a leak inside the boiler (now fixed) but since then the boiler will not fire up. The boiler fan will start but I do not hear the normal whoosh noise I would expect. I took the red plastic cover from the burner and there is no visible sign of water ingress, so I am not sure what...

Hi, We've relatively recently bought a house with a DDC420 controller and are struggling to understand some of it's behaviour and wondered if anyone could help. The main problem at the moment is that the boilers seem to fire even when there shouldn't be any demand on them. An example from...

We have no hot water and it sounds as if the boiler is failing to ignite (when the timer turns the boiler on for hot water we just get a repetitive pinging/banging noise and only lukewarm water, while the heating system is fine). We did not have this problem until 2 days ago. Before that...

Hi, Does anyone know if the Eurostar 90 requires a flue specifically for that boiler, or if a generic flue of the same dimensions would suffice? Proving to be tricky to source a flue for this old boiler. So far have found this one... https://www.bhl.co.uk/trianco-1000mm-horizontal-flue.html#...

Hi guys, I’m having an issue with an HRM Wallstar oil boiler. I have completely replaced the burner for brand new but it is still going into lockout. The pressure is building up and it fires up then gradually the pressure drops off and goes into lockout, if I manually bleed off some oil before...

Hi there - we have a Grant Vortex wall hung oil boiler. It's been giving us some problems locking out all the time, and we've had a plumber visit and carry out various things, which have got it working for a bit... and then it lock out again. So far, they've changed the photocell, the control...

Hi, I have moved to a house with a oil Combi boiler and a thermostat (Grant) which is on the wall in the kitchen. Can I replace this with my hive receiver do you know? I'm a joiner to trade so very limited ability with things like this although I replaced my old one but it was like for like...

Hi, I have a Potterton Statesman oil boiler using its integrated stat for temp control. The boiler fires up as normal as far as the stat is set below half way (unfortunately not hot enough to heat up the house in cold weather). If the stat is set above half way, the overheat light (red one)...

My old grandee oil combi boiler is now 14 years old and during that time it's had a few repairs on it and still going strong but I have yet to meet a engineer to say anything good about them. Anyways, the combi is now 14 years old and it's seen better days and unsure how many more years it can...

I've always just assumed that the colder the return to the boiler the more efficient the boiler would be (i.e. greater differential so heat transfer through manifold is faster). But I've come across direct evidence to the contrary (e.g. boiler recommends minimum 60 degree return, 'hearth' temp...
