The appraiser recommended a $3500+ gas fired boiler but we don't even own the house yet!!!
We built our dream home with an outdoor wood boiler with an underground piping system,
that comes into the house and then goes to a manifold from which pex tubing goes throughout the
house as underfloor heating. The inspector stated that we had to have another form of
strictly wood heat. We argued the matter, but he insisted that
the state code required it. Initially we were going to go with a high efficiency propane
hot water heater tied into the system, but at the last minute the inspector reneged and stated
that he couldn't/wouldn't pass it because he didn't feel that it had the capacity to keep
the temperature at the required level to live comfortably. We then examined our remaining
options and I purchased a number of electrical baseboards, but nixxed that idea as too expensive
to maintain. We finally found that they made a super large *(80+) gallon Comdicore which is
a very well insulated double tank propane fired water heater and plumbed it into the
system coming from the outdoor wood boiler. We use it for our domestic potable hot water and it stays
hot enough to do the dishes, several washer load of clothes and plenty of showers for around
2 days before we have to heat the water again. That baby set us back around $1200.00,
but it enabled us to get our certificate of occupancy. It is 'supposed' to come on automatically,
should the wood boiler fail to provide heat, but I've never finished the final connection.
Perhaps one day when I'm too old to fire up a chain saw or carry the chunks of wood to feed
the monster.......but until then, the propane gets to stay in the tanks set up outside for that eventuality.
BTW: I understand that there are some brands of wood boilers that are multi-fueled and use not
only wood, but natural or propane gas or oil. Might check into those options as well as a solution.
