heat only boiler ?

[royston]

Got to quote for a replacement old glow worm wall mounted. Gravity circs to cylinder and pump on heating. They are not keen on a combi, dont want to spend much (as per usual ) and want to know if i can just replace like for like.
Now i dont think you can as im sure it needs upgrading to a s or y plan. Whats your thoughts on this one ? Cheers.

I'm sure you're right 'royston' ... There ain't an 'A' rated boiler that'll do gravity!!

gravity is dead theres no money in a system that will work with out fail for 20 years its all about thermistors and pcbs which generate money

She even asked me if i could use the old flue on the new boiler !!! Dont even think its worth quoting as every price is gonna be to much !

Full flush,convert to fully pumped,system boiler...leave quote>like it or hike it.

I think Viessmann do a four piper heat only, possibly the 100 iirc.
Using this four piper, you can use the existing gravity feeds to and from cylinder, and put an additional pump and 2 port on the what will be the new flow to the cylinder.
