How should a boiler run?

Larry_10

hi I have a buderus boiler g115-28
as I understand it it's a cold start boiler

my boiler has hydro air and runs 6 mins then shuts off

then run 1 min and my t-stat is satisfied

my boiler is set to run to 180 dose this should like my boiler is over sized.my load is 50,000 btu

what can I do so it dose not run twice in one heating call
should I put a 2107 control on my boiler

and use outdoor rest or lower my boiler temp to 160

I also use the 42gal hotwater tank and there is a 2109
controller

thank you
Brian

wow sounds like the same problem im haveing. i spoke to buderus and told them this. and they thought that maby the r2107 will fix it becase your thermostat dose not control the buner.

i also use baseboard heating on with my hydro air but it's set to zone 2 im calling my contractor today to order my r2107

oh one more thing don't try to under the burner by changing the nozzle buderus dose not recommend this as it can cause condensing

good luck
