Confused about Stove air intake requirements/instalation

davemorton

I am looking at getting a stove and wanted to get a 5Kw one so that I did not need the added complication of having air vents installed (1970's house).  I am busy choosing a stove, and one that I like states it is an air-tight stove, compatible with low consumption houses and that it is compatible with RT2012 standards enabling it to be connected to a ventilated air supply.
Does this mean I would have to use its ventilated air supply, or will the stove be okay installed without it?  
I do intend to get a HETAS engineer out to instal it, but at the moment, just trying to choose stove.
Many thanks.

If it's air tight and not connected to an external air intake, how is anything supposed to burn in it?

With most 5kW or smaller burners, it's assumed that the amount of air they need to suck in from the room is small enough that you don't need extra ventilation. But you may need to check if there's an extractor fan nearby. There's a risk that an extractor may suck air and fumes down the flue and into the room.

It's the air tight bit that got me.  I was presuming that if a hose was not connected to the ventilated air supply on the bottom of the stove, it would just get its air from the room, but unsure if this complies with HETAS fitting regulations.  IE. if it has this option, then it must be used.

I'm guess that in a modern build where ventilation is very tightly controlled it may not be possible to fit a stove without some sort of vent.

TBH you'd really need to speak to the manufacturer, supplier or HETAS installer to be able to assess the implication of what an "air tight" stove requires in terms of ventilation , rather than rely the collective wisdom (or guesses) of the forum however well meaning they may be.

That made me chuckle !!
