baseboard to runtal

clammy

Switching reg baseboard to runtal rad for a bath 3/4 baseboard and runtal is1/2 should i use a 3/4 x 1/2 monoflow tee and pipe that way or just continue the seris loop and reduce it ? i feel the mono flow tee on the return should be fine any input would be thankful peace

on the seies run...how many btu?

Runtal says you can do up to 30,000 on a series loop. A mono flow would be more desireable. Or you could do what I just did and Homerun it to a manifold. I have a kickspace, a 24' runtal loop and a panel rad run to a manifold w/ 1/2" pex. kpc

btus

I believe it's a 3400 btu unit i did not size or order it ,it's a large 2 nd floor loop doing3 bed rooms and 2 full baths i tryed to get them to split the loop and put some radiant in the floor and new shower enclosure but no go i,m hoping that with the mono flow it doesn't effect the flow through the rest of the loop and with the series piping thr reduction from 3/4 to 1/2 will definatly effect it .I tryed that pex home run deal but it was a no go but by the time i get back there next week they may change there minds first i'll take care of the other stuff like re roughing the waste and water line doing for a close friend s brother he's already been cool enfoght to switch his central a/c this past summer and before that he took the step with replacing his old boiler with a gas buderus unit 2 winter ago here's a shot of that thanks and peace

BTU's

Thanks the runtal unit is 3400 btus i did not size it or order it the HO did but he,s a good egg and did the right hthing i tryed to talk him into radiant and the whole home run thing but he didn,t go for it.What i was wondering was in the reduction from 3/4 to 1/2 if i connct it in a series i,m cincerned about the effect on the flow to the rest of the loop also this zone is workin off of zone valves and the bath in question falls somewhere in the middle of the loop. the HO won't go for spliting the loop which is not to hard i tryed to get him to radiant it but no go .Am i really better off just going with my first thoughts of a single mono flow on the return side thanks for the input here his buderus i installed 2 years ago Thanks again and peace

Same thing

I just did the same thing to my bathroom. Used a 3/4 x 1/2 monoflow because I was also worried about the flow. Works great and didnt loose flow down stream.
