Most efficient boiler for a 4 bed house

[mebuild]

Hi can anyone steer me in the right direction on the best GAS boiler to run a 4 bed house it will have about 9 rads over 3 levels (after loft conversion) i have been looking at a worcester greenstar 34cdi this seems to be A rated
thanks for your time!

Too many to choose from IMHO. You'll find that they are all a-rated more or less. Efficiency... The boiler is just a small part of it.

Hi mebuild.

As Howsie has said, regulations have changed over recent years, and there is now little to choose between new boilers in terms of efficiency.

More important is a system design that suits your property and lifestyle, suitable controls, and of course other energy efficiency measures like insulation.

Ideal vogue is probably most efficient boiler I've fitted. Modulation is excellent, must drop condense 5/6 times in 20-30mins.

That remains to be seen. They're doing their upmost to convince me their flagship model is amazing.

Any boiler that you have fitted will have to be an 'A' rated condensing boiler.

If your after an efficient boiler, you'll want one that condenses in both hot water and heating modes, most combi boilers only condense in heating mode, meaning they are less efficient when being used for hot water.

The Intergas combi range is one that condenses in both modes, resulting in higher savings.

If you really want to maximise your efficiency, think about other controls, like room stats, weather compensation controls, TRVs, seperate zones.

Good point that pal, WB have been doing that for 12 years with the HE and now continues with CDi range

 

[Danv44444]

Crap flow rate?

 

[hammers4spanner]

wouldnt need a 7 year warranty if it was anygood

Have a read of Vogue have a look thread......basically TB fitted a 32 kw one replacing an aged Vokera, hot water was less than good, even though the Vokera was only 28 kw I think, so Ideals solution is to replace the 32kw vogue with a 40 kw vogue hhhmmmmmm

What do you fit hammers you ain't said?

going by the above comment cannot be WB, Vaillant, Ideal etc

[Danv44444]

No prv to do on viesmann either

 

[hammers4spanner]

I'm honestly not fussed just get on with whatever is in hand to be fair its the job i'm trained in so turn up and crack on use to do two heat packs a day now cant be bothered .Been doing two boilers a day tho at mo which now starting to get bored with .

Yeah the later ones are ok, but early ones riddled with faults, div valve, PCB's, flue seals etc good idea the PRV into condensate, others should follow!

Aww I see you on your own or a team? 2 a day is some going with flush and benchmark paper work etc...I am a bit fed up with the trade at the moment, roll on spring...

 

[hammers4spanner]

You keep saying this, I don't get it lol. How can fitting it right stop plastic from cracking?

You must be the only one in the north of England that's fitting them right then Vern, cos I've never seen one that wasn't pants.

Some going that pal, I must be getting too old!.......

 

[hammers4spanner]

aint that bad to be fair , heat packs are no go for me now tho

 

[TBServices]

Some going that pal, I must be getting too old!.......

Takes me an hour to fill out benchmark and teach customers how to use controls. Takes at least another hour to flush properly (assuming no powerflusher). Leaving approx 2 hours to decom old and fit new boiler, possibly uprate gas and run new condensate. I couldn't do it and I wouldn't want to.
