or can I install a commercial boiler under 70kw on a domestic ticket? In other posts, it has been debated but, with differing views.

what sort of property, what sort of set up u looking at?
If it is branded as commercial you cannot fit it regardless of the size, I called up Gas Safe about this a few months ago.
Does it have to be a system boiler? Worcester do the 40CDi, you could just fit external vessel and PRV as if you need a 40kw boiler chances are you are going to need an addition vessel anyway.

it is a church, which has been turned into separate rooms. and an unvented cylinder BG installed, but with an immersion for now. But has primary side also. No, it doesn't need to be system, it can be heat only and convert.
40kw not big enough

the ideal is a commercial boiler isn't it
also, i need to quote for a 60kw boiler upstairs to run underfloor heating. Think I am way out of my league on this one.

So you are going to have a total of 60+50kW installed? if so better pulling them all together into a single plant room, 3 x 40kW boilers in cascade on a low loss header, then taken off to points of use from there.
awesome, that boiler looks like the kiddy. Not cheap though are they. And that is domestic? 3 of them is a great plan, will be a nice job that. They have given me a big external wall to put boiler so will advise that they build around them as in a cupboard.
have just seen, it's a commercial boiler

for what that costs you can get 2 x potterton 40 kw titaniums with a 7 year warranty,they just need 1 hot outlet each to work and via the controls output wiring will work as system boilers Potterton Titanium 40HE Combi Boiler, Flue & Clock - Mr Central Heating
They look nice. I have heard they are quite expensive though. And by the looks of their site they only have upto 60kw which means it has to be domestic. Nothing listed under their commercial link
Core blimey, they are cheap aren't they. And a good warranty. Not sure where i would run the hot, as an unvented cylinder just been fitted

TBH roger seen one in the merchants on display they look very flimsy
you got me thinking there. Nice that they come recommended by one of the main guys from the forum with experience too. unrelated, but i read in the heating design guide today that a system boiler supplying an unvented can only be 45kw. What is the reason for this?
oh really!!!!!
