to monoflow or do it without monos

allenh

The house came this way... gas boiler in basement, 2 floors living space, plus an unheatead and unfinished trussed attic.

First floor has baseboard loops and a couple of kick heaters off a 3/4 riser - no problems.

Second floor is the issue. There are 4 bedrooms and one bath. Every room has a separate kick heater. Walls are closed and not going to be opened up.

Attic - above second floor - has one loop. Off this 3/4 loop are 5 kick heaters. The person who did this work in the attic apparantly had never heard of a monoflow T. So when he connected for a heater below they used an elbow and reduced to half inch. This of course restricts the heat big time and the heaters at end of loop barely get any heat.

I am attaching rough drawings. One is the side view of the place, next it a view of the run if I was on top of roof looking down. The next one is if I do this in monoflows. And the last one is if I do this with T's.

I know that this board has great knowledge. What would be more likely to work? Monoflows or just T's? The drop down from the attic is aprox 8 feet to the kick heater. All kick heaters are totally plumbed in half inch. I am currently using a taco 007 circulator for each zone.

If I go with regular T's would I need a larger pump head?

You could try this...

You should use valves on the kicks that you can balance the output if you need to. Then if you don't get enough heat, you'll need to go to phase 2 and address getting more heat up to that level in total.

You need monoflos

If the emitter is below the loop use a monoflo on each leg. If the emitter is above the loop use a monoflo (B&G) on each return. Don't forget to account for the monoflos when sizing your pump.
