Ha Dan Primary Secondary Problem

Mitch_6

Show Two boilers tied into the Primary loop one after another. In a Two boiler install with a Tekchmar staging control this seems to work OK since not all the time both boilers fire.

I have a case were four boilers are tied in like this and the last boiler receives so much temperature from the prior three on peek demand that it barely fires.

It seems tying all the feeds together then all the returns together then going in the the primary is a better way.

Just my observation.

I agree.

That's the best of the two options, and I think I have that in the Made Easy book, but I don't have a copy here to check. Thanks.

Yes Page 111 of Made easy shows this

Unfortunately we did a job using page 111 of pumping away about three years ago. Using four boilers.

Live and learn.
