Trinity 150 with boilermate issues
Hi, I have a trinity 150 boiler with boilermate dhw that was installed back in 2007. We've had very cold weather the past week and I have been noticing issues with the system. The dhw is run through an auxiliary circuit that cuts the main circulator out in the loop, and is installed just before the main loop circulator. The dhw then feeds back into the main loop about 6" past the T that feeds the circulators for the baseboard heat and 3" above the return line for the baseboard circulators. When the dhw is running it cuts the main circulator but not any of the zone circulators. So the boiler seems to run continuously and not get upto temp if dhw is calling and zone pumps are still running. I'm wondering if there should be a check valve just before where the dhw T's back into the loop. Could the zone circulators be circulating the dhw through the baseboard before it reaches the boiler since the is one circulator running the boilermate and 4 circulators calling for heat all within an 7" section of the main loop? I've been getting ER6 on the trinity panel which I believe is an ignition or flow problem. Could the zone circulators be starving the boiler of flow when the dhw is running and the maine loop circulator is off, but the zone circulators are still calling.when the dhw is turned down down and stopped the auxiliary, the main turns back on and can hear rushing water like a toilet flushing. The system then seem to run fine but take a long time to recover due to the down time from the dhw seizing the flow.
