Stove with or without external air supply

Effects

I'm currently looking for a stove for a new build. I'm finding it's not that easy to find an external air supply model that's 5kw, free standing and within budget. The space is 156 m3 for the open plan floor it will be used in.

I'm wondering if a standard stove without the external supply would be possible to use.

Is there any way to find out how much a non external supply one will affect air tightness/MVHR system?

I've found this online:
Go and work out the air flow through a non room-sealed stove at full blast. It's surprisingly small - a Dunsley Highlander 5 stove for instance gets through 3.9 g/sec of air - 14 kg/hour. Air has a density of about 1.2 kg/m^3, so sucking in 12 cubic metres of air an hour at full blast. For my house, a 5kW stove is enough to keep the whole place at a comfortable temperature down to somewhere just below freezing, and the house is about 220 cubic metres - so the stove is responsible for somewhere in the region of 0.05 air changes per hour. That's trivial - so unless you have a very airtight house I think there is minimal value to room sealing a 5kW stove.

Should the stove manual/spec sheet give me a figure for the amount of air it gets through?

Being pressured to decide on the stove as the flat roof is going on soon.

What's the budget?

The budget is €1750 for stove, flue and flashing.

Forget it, you won't get a room sealed stove for that money.

Qesution you should be asking your arch/Eng who ever is signing off on building compliance - is will you need a hole in the wall to comply unless it's a room sealed stove..

Yeah, will probably need a wall vent.
Waiting on engineer to work it out.

There are room sealed stoves for that money. There just aren't many at 5kw to choose from.

Whomever is designing your mvhr system had better understand what your stove plan is

We are probably going to go with the Henley Kylemore 7. The firebox on the 5kw version is too small.
The one we wanted was the AGA Ellesmere 5, it's got a good size firebox, but it's not external air.

Both sent to the engineer to calculate.
