I have an Burnham Alpine boiler installed in our home. As I understand it a zone should be set up to have a delta T of about 20deg to be most efficient basically. We installed a Taco Bumblebee circulator in the main loop for the downstairs in my home. It is approx 100' of standard baseboard...

Hi, I have a 40 Gal Superstor water tank with a mixing valve heated by my Burnham AL80 gas boiler. The problem is we often run out of hot water after a couple of showers or a laundry and shower. The other issue is in the very cold days it has priority so the heat goes off while its running and...

Hi, Its been quite a while since I posted last. I learned a lot and was/am very grateful for all the help. With the very cold wx here in New England some new problems popped up.

Hi, I have a Burnham alpine ALP080B installed about 9 months ago. It has worked fine till this cold snap we are having. The plumber that installed it had no idea how to set it up although the installation was very well done. I have taken the time to read the manual several times but am at a...

I am having a little problem trying to decide how to properly set the primary D/T on a P/S plumbed boiler. I replaced the primary pump on the Alpine 80 with a Taco Bumblebee as the pump curve showed it matched very closely what I was looking for. I wanted to get a 35* D/T across the boiler so as...

I have have a new installation with 3 zones each fed with their own zone pump. It seems that in the upstairs zone there isn't much heat comming out of the BB even with 160* water. I am thinking tht perhps there is air in the line. I do not hear any noise of water running. I just cleaned all the...

Hi, I just had a new heating system installed in my home. It is a boiler/baseboard system with 5 zones. I have now discovered the installer really didn't have a clue as to what I really needed. He did no heat loss study and just assumed the old boilers rating was what I needed. I have ended...
