1/2\" convector in 3/4\" zone

hr

pipe it with a bypass and a ball valve for flow regulation. 3/4 x 1/2 tee, then a 3/4 ball or globe valve, then another 3/4 x 1/2 tee. That is IF you have access to the valve to adjust flow.

1/2\" convector in 3/4\" zone

I bought a kickspace heater for the kitchen. It's plumbed in 1/2" (about 4' total) but the zone will be 3/4" and 4 GPM. Is this a bottleneck worth dealing with? The spec sheet lists a pressure drop of .422' @ 3 GPM and 1.026' @ 5 GPM (it'd be nicer if they just gave me a curve) - is that small enough to ignore in a 150' run with several turns and 3 convectors?

If I need to deal with it, what are my options?

thanks,
jim

You should pipe it with one regular tee(3/4x3/4x1/2) and one monoflo tee(3/4x3/4x1/2).
The first tee is reg. and the second is the monoflo.

Hot Rod is 100% correct. Pipe it just like he suggests. I've been doing them like that for 15 years.

thanks

I was hoping the monoflo would be a solution, given the simplicity, but now that I think about it the balancing valve is probably better from a "system" perspective. The kickspace heater will be in the corner of an L shaped kitchen with an island, so being able to control it would be nice, like turning it up for morning coffee but down for ovens-blazing Thanksgiving, though that might be putting too much faith in the homebuyer. Hmmm...maybe a TRV on the rad piping and leave the bypass open? It does have a normal-off-boost switch for the fan motor though.

Gah. This design stuff really sucks one in. It won't be my house. I'll put in a balancing valve with a note on it and call it good. :-)

One more idea

I did this in the same situation, I added a 110V thermostat in the kitchen which controls when the fan is allowed to operate, a simple and cheap way to make a zone.
