Plumbing / Sidearm Plumbing Question
« on: February 22, 2012, 05:43:22 AM »
Hello Everyone,
I've got a plan and need some confirmation that it's going to work.
I have PEX-Flex with 1" ID inner pipes coming into my basement, 170 feet from my OWB. My plan is to use 45 feet of 1" PEX to travel through my basement over to a sidearm (3/4" inlet and outlet sizes) on my electric water heater, then 45 feet back to a flat plate heat exchanger that delivers heat to a radiant infloor system and an iron rad system. The basement is unheated, but I'll be putting lots of insulation on the 1" PEX lines as they travel to and from the water heater. The hot water circulating through the sidearm and one side of the flat plate exchanger is part of the main loop that goes back and forth to the OWB. The radiant infloor system and iron rad system will be part of closed loops on the other side of the flat plate exchanger.
Will this set-up deliver enough heat to the radiant and iron rad side of my system? Should I be concerned that the 3/4" fittings on the side arm will restrict hot water flow too much? Will the heat siphoned off my the side arm to the water heater limit the heat delivered through the flat plate exchanger to the rest of my house?
I'm thinking that this set-up should work fine, but just need some confirmation from experienced OWB owners before I set it all up.
Thank you all very much!
Steve
