OK tell me if I am taking on too much or is this a DIY project. I presently have a gas pack with propane furnace and AC unit. all mounted outside. I want to install hot water base board heat. I can install baseboard heaters and pex (oxygen barrier) I would buy the heaters and install . Its a 1900 sq ft house and I would use 2 circuits. I would run the in and out pipes to crawl space and plan to install a Propane fired Lynx combi hot water boiler with 2 taco pumps. I am capable of plumbing and have the tools. I have recently rewired my house with inspections. I am 75 and my crawl is 5' where I plan to put boiler and goes down to 2' at the far end. I would use all 3/4 " pex with copper going from baseboards thru floor then go to pex. Is this a good plan? what do I need to change. The boiler is high efficiency with PVC exhaust thru crawl wall.
