Subject: Re: Passivehouse in Vermont? - Wood Stove

Thank you for the input.   I agree with Robert's concern about using high technology for controls.    

That is why my plan is to use a HRV with simple timer controls.  I am looking for one without a microprocessor.  Any leads?   A few electro-mechanical timers on the shelf in the basement will keep it running for a long time.  

On the wood stove,  we need hot water and a place to cook, plus the ambiance.     There must be a way to do this.   

The wood stove should be able to provide both.  But with the Passivhouse, the heat load is so small the Vermont Bun Baker stove will probably overheat the house, even if I use it to heat water.   

I passed on the masonry stove option for the same reason, it even costs much much more.      

This unit is close:  http://euroflues.com/products/fireplaces/woodstove/pallas-back  but doesn't have the water heater.

Options from this company http://www.wodtke.com/waterplus.html are even better, but they do not have an importer in usa.   Any wood stove companies want to take this on?
