I’m building a 330 sq ft tiny home and considering in slab hydronic heating. I love the idea of on an on demand water heater (mounted outside means no sq. Ft. taken up) serving the dual purpose of domestic hot water and heating the home.
I am currently dealing with Radiantec as I like there DIY kits.
Anybody have experience with open direct systems and/or Radiantec??
I am a noob and first time home builder.
