kerr titan help

MILL VOGGINGTON · Jan 9, 2014

hi, i have an older kerr titan boiler,i had a hvac person hook it up to my baseboard heat,the problem is its a 3 zone setup up 2 house zones and the garage is a dump zone,when one zone is calling for heat the other zones still have water running threw them,the garage zone is 40 degrees so its pulling the heat out of the boiler when that zone should not be circulating should there be check valves for each zone to stop flow to other zones or what do i have to do.if i shut the ball valves to the garage the boiler heats up nice and sleeps even with a zone calling but with the garage open it cant keep up

what i have is a 3 zone header with 3 taco pumps with a taco zone control unit,i think he plumbed it like an oil boiler

Sounds like he needs to come back & fix something. Could be pumps running when they're not supposed to be, could be pumps that are missing check valves, could be something else.

No check valves in the pumps i know that, so there are no check valves on the system

I'm no plumber but I had a Kerr boiler (stainless steel) that looks like yours with the same basic setup...two main floor zones and the dump zone in the cellar. Each zone had a thermostat, I set the cellar thermostat low so it never called for heat, but there was an aquastat (I think that is what it is called) connected to the boiler which turned the cellar zone circulator on when the boiler got to a certain set temp. Worked fine for more than 30 years. I finally changed over to a gasification boiler with heat storage which also has a dump zone but that has never had to dump heat for the three years since it was installed. Your setup looks somewhat more complex than my former system.
