Bit of a newbie here.
I'm looking at a Turbonics hydronic heating system with mainly wall-mounted fan units.
1) The Taco circulator cartridge is running a lot and the body gets pretty hot pretty quickly. How do I know if there's a problem?
2) How do I make sure there's not air in the system and take it out if there is?
3) Is flushing the system something I can do myself?
4) It says "hot water only". In all this heat, please, for the love of all that's holy, tell me this is wrong and that I can run some cool city water through it, at least for the next couple days.
Thanks so much,
You folks are awesome.
