We are renovating our slab on grade house and currently use a thermopride oil furnace for our forced air heat.
Our house is mostly slab on grade, with 200 square feet of floor over basement. As part of the renovation, we are going to switch from forced air to radiant. We are going to install radiant in the common living areas, kitchen and baths as there will be access to he slab/joists. The pex tubing will be installed on top of the slab and under the plywood subfloor. We will use a strip hardwood floor (stable solid wood) throughout.
We will install 2 other zones of radiant baseboard heat-one for basement and one for bedrooms where we do not have access to subfloor.
Contractor is recommending a Burnham MPO 189 unit and Phase III indirect water heater. This seems to be a high quality pairing. We are served by well water. Contractor has run heat loss load/Man J and seems to know what he is talking about.
Based on the above facts, does the system seem good?
Separately, our thermopride furnace is about 20 years old. Heating company won't give us any value for it, but they agree that it is a great furnace. Does anyone think there be a market for this?
