Title: i need help to bypass my heat exchanger for the summer
Post by: adamant on April 27, 2008, 06:20:00 PM

i think i got it.
cut the IN water line and the OUT water line on the hot water heater (green pex) put tee's in each cut with valves and thats it .right? see pictures below.
i didn't do the install but i am sure i can bypass the h/e in the plenum.
what do you guys think? 

i hate to go with the pex fittings because i would have to buy thre crimper. i was thinking about the SharkBite® Push-Fittings.

Hey

I just had my boiler installed and asked the dealer about adding a bypass.  He installed something I think is even better.

He put a zone valve that runs off the the furnace thermostat.  When the thermostat sends a signal to heat your house it also signals the valve to open to allow the boiler water to flow through the heat exchanger.  When the thermostat sees that the temp is adequate it sends a signal to the furnace fan to stop and also sends a signal to the valve to close and bypass the heat exchanger.

I haven't gotten the install bill yet but I think the valve runs around $150 or less.  I believe it is made by Taco, the same company that made my circulator.

Hope this helps.
