I'm installing a new heatmaster. I added a kickspace heater in my bedroom as it is sometimes cooler in that room. It uses 1/2" line.  I have a single loop running to my sidearm, then going to my water to air in my furnace, then before the line loops back outside to the furnace I have a 1"X1"x1/2" tee then 14inchs down the line is a Venturi Tee where the return from the kickspace heater goes back into. This is plumbed the way the kickspace heater instructions stated.  Will I be able to get all the air out of the lines? The instructions showed having a air bleeder before and after the heater but the Heatmaster is not a pressurized system so I hoped all the air would work itself out. Am I living a dream or will it work.

I would doubt there will be enough flow to drive the air down without forcing water through the line.

If you put a valve between the tees you could easily bleed the air out by just closing it till the air is all flushed out.

You know I thought about putting a valve In between cause it would have to force the air out. My only concern is a valve is smaller than the normal 1 inch pipe and I didn't wanna add more restriction to my loop

The Venturi Tee on the return side is suppose to create a suction and help with the flow though the heater

Will using galvanized bushings the loop hurt anything?  I have a 1.5inch ball valve. I could use two bushings to step down to 1 inch. Then thread 2 1inch copper male adapters into the bushings and sweat that between the tees.  That big of valve wouldn't cause Any restriction

[slimjim]

You can buy full port ball valves.

[Jared43758]

Never heard of that.  Will the galvanized hurt anything?

Some boiler antifreezes say right on specifically "not for use with galvanized". If your not running antifreeze and never plan to....

[Jared43758]

I never plan to use antifreeze. I'll be running a heatmaster and I don't think it's nessasry. SlimjIm can chime in

Will usin black pipe bushings hurt?
