Muggles, how long have you worked for houndsfield ;-) My question is- if both boilers are set up properly by the same tech to the same output would there likely be much difference in efficienc??

Hi gents, just an add on question For the grant experts… Is there likely to be much efficiency difference between a Grant vortex 15/21 vs a grant vortex 15/26 if both are set to circa 19kw?? the 15/21 ( now discontinued due to range being reduced- but I have 3 at work) claims 93% efficiency at...

Cheers muggles, I have looked up hounsfield previously but no one in my firm has ever dealt with / sold them….. not even our Isle of Man nor North East England division. Never heard of EOGB. I’ll have to Google them. Thanks for the suggestion (y)

If it’s set to 18kw ish I would be happy enough as is because I assume it would give faster recovery of the cylinder when it’s cold and there is all round demand. Thanks Exedon (y)

Thanks for the replies gents. I was focusing on grant vs warmflow as they are both very common/popular in Northern Ireland where I now live and therefore servicing shouldn’t be to tricky to sort. Also I can get both very cheap through work. Also it looks very much like the original firebird...

Hi folks, I’m back again after what must be 5 years or more for some advice / opinion. My quandary is: Grant Vortex vs Warmflow Agentis??. The only thread I could see about warmflow was very disparaging in terms of warmflow customer support (or lack of it). My plumber says it’s up to me...

Creating a new whopping great hole from a warm humid living space through into a very cold and poorly ventilated loft space will obviously cause lots of condensation. Overtacking the existing plasterboard with 12.5mm plasterboard and wet plastering it will give you good fire resistance and sound...

Scribing is best but it isn't worth trying it yourself unless you are good at scribing, which even some chippies are not. Get it all cut exactly, use mitre mate to stick it together first and then position it and fix it to the wall.

Thanks again tony.

So would setting the cylinder at 55 and the boiler at 70 be advisable ? Or would 60 and 70/75 be better- I want a fast recovery for hot water and the rads to warm the room quickly too. Cheers.

Also- my thermostatic power shower suggests hot water input at 65c for best flow rates. 55-60 seems reasonable until I get an anti scald valve and shouldn't affect the shower too much. Cheers

Cheers tony, I think the energy saving trust etc use 65c as a recommendation due to it killing legionella instantly- but obviously regularly heating the cylinder to 55-60 stops it growing in the first place. They also mention using a anti scald valve to bring it down to 55c

just wondering how hot I need to set the temp stat on my boiler to enable it to heat my cylinder to 65c? All the info online just says to set the boiler to a hotter temp than the cylinder temp but not how much hotter it should be. It is a firebird conventional oil boiler with a 3 pipe system...

Ok boss.

Steelmason- I have no interest in your issues.

Do any of you guys use the fire blanket for sealing the baffle door ?? The locals who advised me- for free, said they do not and would not use anything else! Cheers

I am also paying for the time the service guys spend so I am not 'tyre kicking'- just trying to get the best advice.

Apologies, where I live there are plumbers who do installation and engineers who do repairs. So I'm just trying to be fully aware of what the options are. No disrespect intended

Cheers John I will ask the tech to check pump pressure when he is here. I am sourcing 2 guys for pricing a replacement and 2 others to advise on how to save the firebird so shall see how that goes... All comments or advice appreciated

I was imagining a Diesel engine losing compression when I asked the question about it cutting out so your answer goes with that a bit... Would a combustion chamber leak cause intermittent flame/firing failures? Cheers
