Heat ventilation system for basement

I am in the process of creating a second suite in a basement that requires separate heat from the upper main unit (cannot share furnace or ducts). I am thinking Hydronic baseboards are my best option but from what I understand since the heat is radiant and not forced like a furnace, I also need some sort of HRV system.

The problem is the basement will be ductless and from what I understand HRV systems are connected to the ducts/furnace. Is there any alternatives?

Any other heat source suggestions other than baseboard are welcome too.

My unit is 1 floor, 650 sq. ft. 4 baseboards connotes to water tank.


I'm leaning towards a Rinnai Wall furnace (16k BTU) and 2 electric baseboards, 1 in the washroom and 1 in the bedroom.

Hello Anthony,

Baseboards are a good option for this if air conditioning is not a concern for you.

HRV can be ducted, but they don't have to be complicated. We can run 2 or 3 runs into different rooms and keep it fairly simple.

Hi Anthony,

Have a look at mini split heat pumps. Electric but very efficient and they can provide heat when the outside temp is -15C. They also provide cooling in the summer.You could probably use a 9000 BTU unit. HRV units can be standalone but they will need a few ducts installed.

Good luck with it.

I'm actually leaning towards a Rinnai Wall Furnace with 16,000 BTU's Reliance sells them, and 2 electric baseboards (1 in the washroom, 1 in the bedroom). The Mini split might is a concern due to the -15 cap.
