We have a 3 year old home about 1750 sq ft main level and same in the basement, along with a 900 sq foot garage (12' ceilings). The house is currently heated with a NTI Ti 150 propane boiler, forced air for the main level of the house, radiant floor for the basement and garage. The boiler also does the domestic hot water (we have a 60 gallon holding tank). The house is fairly well insulated (R-40+ Attic, R24 exterior walls house and garage). We live in northern Ontario Canada climate and have lots of wind exposure. Propane bills are getting expensive, so I am looking at a OWB to save money in the long term. At this point I am thinking of sticking to a non-gasser stove, to have the ability to burn anything and to keep the stove simple.
I can easily get a Portage and Main, Central Boiler or Heatmor boiler (so far). I was looking at the Portage and Main BL28-40 (new model), the Central Boiler 5036, or the Heatmor 200 CSS. Any opinions or experiences with any of the above?
The new Portage and Main model looks impressive with the brick lined fire box and its claims at burning a high efficiency rates without being a gasser. But it is a new untested model, not sure hoe different it is from the old ML-30.
BL28-40 Outdoor wood furnace by Portage and MainThe Central seems to be a tried and true design. A good friend has had one for 10 years and swears by it. It seems to be an old and proven design, but maybe inefficient.
The Heatmor is stainless steel which sounds good, but then the competitors say that stainless has cracking problems.
How much smoke does a non-gasser produce? Does the chimney's on these hae to be higher than the house peak if the unit is close to the house? We have strong winds, and the location I am thinking will have the house down wind (generally) from the stove. The garage is on this side and is very tall.
I am sure I will have lots more questions as time goes on, looking forward to some discussion.
