Ok so in order to get us through this winter I needed to make a retrofit so to speak. My slab developed a leak, in our 1947 levit. on the main loop. we also have an extension in the back of the house that has a radiant zone. this was not leaking but I decided to abandon it to add some baseboards.
The pipe for that zone goes under my slab and under the staircase, where the pump, and expansion tank are located. this is piped in 1/2 copper.
I used this pump and expansion valve and capped off the radiant, and added 40' of baseboard. Using 3/4 pex (o2 barrier) to pipe the system
I bled the system a lot. closing the boiler return and opening the purge valve before the boiler return. the pump comes on when called for heat, and the boiler temp gauge is 180 (what the aquastat is set at) the pressure is 27 psi hot, and about 20 cold.
I just done seem to have the heat output that I would assume, the supply is 140 and the return is 80 (this is measured with a IR gun) we don't use the boiler for DHW we use electric for that
any help would be greatly appreciated. no one even wants to touch this system. this is just a fix for the winter, as I will be moving the boiler, to the garage come the spring (and money)
