How controllable IS hydronic radiant floor heating zonally?
I am now looking to assess the possible value (comfort return on investment) of including hydronic radiant floor heating in my build, a build which will be based on a floating raft slab (fully insulated) in zone 4C.
I’ve read of folks installing lines but never deploying the system (the supporting). I am thinking of perhaps hedging and at a minimum instal lines: if not me then perhaps a future owner can install the remaining bits. NOTE: I looked at Legalett’s radiant heating using air solution and have concerns about the pipe sizing displacing too much concrete (lose mass) as well as it’s overall functioning; I like the idea of not having a fluid, but that doesn’t mean air is better. With this all said…
Do multiple zones actually make much difference? Are they really all that controllable?
Floor layout is basically a rectangle (51′ x 38′) with one long side/half bedrooms and bathrooms and the other long side/half living, dinning and kitchen rooms. On one end lies mud, mechanical and laundry rooms.
