Ideas

We have a cold spot in our house when using the gas furnace. Since I’m switching to the boiler using the furnace blower and water to air exchanger I want to take care of the problem. It’s the entire second floor. It’s nive with the radiant heat from the wood furnace but seriously lacking with the gas.

I’m thinking about this and tying it into the trunk line on the second floor to boost heat upstairs and allow separate control up there. Just add an exchanger like I will above the furnace. Think this might work?

Our house at one time was heated with two 200,000 btu oil furnaces, one downstairs and one upstairs. Over the years the house was insulated and the upstairs furnace was removed, however our upstairs was freezing. I ran a heat trunk upstairs through the ceiling into the attic and converted the tiny supply ducts to returns. We now have a few degree difference compared to a 20 degree difference before. While there may have been a better way, it was very cost effective and did the job.
