bypass loop and temp return help

my boiler is fine now, ive asked before this but should i install a bypass loop. my boiler is a non condensing boiler and peerless the manufactor said i do not need one. should i install one to help the boiler from short cycling, or shold i rearange my pipes from longest loops to shortes before entering into the boiler.

should i watch my return temp?i have 4 zones in my house.shortest being a indirect tank. also my indirect tank it says 10gpm i shouldhave flowing through it. my taco pump does not say how much flow it produces.

A boiler bypass loop will make it easier for the burner to short cycle.

Possibly... if it's not needed in the first place. Some systems just don't require a bypass. Most systems that use fintube baseboards fall into this category, as long as they are properly designed.

If it IS needed, and properly adjusted, the boiler won't short cycle any more than any other properly sized and designed boiler.

Tony, I forget... did you install a thermometer on the return line to the boiler? If so, what can you tell us about the return temperature into the boiler?

A bypass is required on systems the run water that's too cool back to the boiler for extended periods of time... large volume systems, cast iron radiators, converted gravity, that sorta stuff. We've been all through this with ya before, hain't we?

Fintube baseboard heats up pretty quick... unless the loops are way longer than good design would dictate, your return water should come up to temp pretty quick.

I dont have a return temp hooked up. i was going to install them to see what it is. can i use an inferred laser to read the temps or does it have to be a temp gauge?

You can use an infra-red gun, but you MUST paint a flat black spot on copper pipe or you will NOT get an accurate reading.
