Does anybody know of a suitable small unit that comes able to take air directly from outside the house, burn in it, and then put it out the flue? The idea being that the burner will not be using the air from the house which will then need to be replaced by air from the cold outside (i.e. needing to ventilate our nice airtight house)

Can anybody point me to a supplier.... or even warn me off following any problems/experiences with this?

Thanks,

There are a few of these available on the market. One manufacturer that offers stoves specifically designed for working with HRV and airtight houses is RAIS. There is an outside air kit for a number of units that takes air directly from outside(through a floor or wall) into the combustion chamber and directly out the flue. Some of the units are even designed for a certain amount of negative pressure in the house (for example if you switch on an extractor fan in the kitchen).

I cannot find specific info on the RAIS site about these units but if you reference the attika site(same as RAIS in Switzerland) there are more details on the units that support this requirement.

Hope this is of help to you...

I've just started to look into this myself to avoid open vents in walls. So far I've found that Clearview stoves can be set up to have air ducted from outside direct to the stove. I would hope some other stoves can also do this. Would be interested to see if you find anything else.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=434&Focus=4900#Comment_4900 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=434&Focus=4900#Comment_4900 Sat, 21 Jul 2007 09:46:16 +0100 KeithH
I have looked into this problem for a timber house I am planning.

HWAM stoves are available with a 'Fresh air system', which couples the stove to an external air supply, It is an option at around £100.00 extra.

Another option is a 'Topolino', a wood burning heat storage stove by Tonwerk Lausen(Swiss). A direct air supply can be taken into the base, ok if you are in a position to take the ducting thro' the floor! others stoves are also avaiable from Tonwerk. Try Construction Resources.

On a larger scale are Soapstone heat storage stoves by Nunna Unni, possibly to expensive but a real statement and very efficient. Direct air supply taken to base of stove.

I shall probably go for the Topolino for its recyled credentials and clean modern lines. See how the budget looks!

Hope this is useful.

Sorry for the time in replying...... been on holiday and banned myself from typing for a fortnight!

Thanks for these leads. I will have a look into them and see how I get on.
