Newbie Radiant Install
I'm set on installing a radiant heating system in an old house (i.e., some, but poor insulation -- lots of heat loss). LP tanks.
From inside the basement, I have open access to the 2x10 16" OC floor joists under the 1st floor.
I understand Uponor pex and heat plates are very good, and I understand (I think) the looping process and runs under 300' and insulation under (lower) the pex/plates.
I understand a boiler is much smarter than a hot water heater (even a tankless), and I'll need an expansion tank, pump, gauges, sensors, drain/fill spigot.
The first floor is about 22x38, and I think 1 zone would be just fine. I'm having a very difficult time doing a heat loss analysis because the first floor extends past the borders of the basement -- that is, there are rooms that are supported by piers outside the footprint of the basement. I was going to just ignore those for now, and leave those for additional zones.
But that's about as far as I got (not that I've got that down pat).
I'm trying to understand the piping at the boiler, and reading lots of posts here and getting more and more lost. Specifically, using the straight through vs. bull (Tee) side of a tee, mixing valves and control circuitry is not something I have any grasp of.
Anyone have any advice on how to proceed? It's January and it's cold and the electric heat is working very hard and costing me a lot of money.
