I noticed this morning that all of my baseboard heaters are 3/4 inch, and that my supply and return loop in the basement are 3/4 inch. However all of the pipes coming off the loop are 1/2 inch feeding each of the baseboard heaters. Is there a good reason for this? and should I repipe the new heater in the same way?
Thanks,
Chris

It depends on what you mean by "loop". 3/4" would be rather small for a conventional "loop", and if it is a series loop, using 1/2" between the panels would be a restriction.

I apologize I was not being very specific and last time we talked about this I am certain it was determined that I do not have loops, rather I have a two pipe system. One pipe for the supply and another pipe for the return.
The supply and return pipes are 3/4 inch. And each of the tee's going to and from the heaters are 3/4*3/4*1/2" Once the 1/2inch pipe reaches the heater a 1/2*3/4 coupling is used to connect to the 3/4 inch baseboard heater.
Should I change the 3/4*3/4*1/2" tee on the supply and return pipe to a 3/4" tee and just run 3/4" pipe to and from the heater?
Thanks,
Chris

it all depends on the total heat load.
how many linear feet of baseboard do you have?
you would be supprised at how small the piping can be if there is not alot of BTU's required.

You may have a monoflow system. How long has it been installed? Does it work well?

NOT with a 3/4" main loop.

if i remember from his last posting, he has a feed with tees to each side of the radiators. then there is a return with tees picking up the other side of the radiators.
just a simple 2 pipe system.

That is correct, I have two pipes, like the illustration packy posted. I do not have any problems in the wintertime keeping the house nice and toasty.
I did a quick measurement and I have ~400 linear feet of baseboard, the bathroom I am redoing is a small bathroom and baseboard is ~20 linear feet, and I was going to put in a 3 foot heater replacing the old 3.5 footer.
Thanks,
Chris

follow the pattern in the rest of the house ~ with the 'restricted' feed and return to each 'rad' almost 'self balancing'
