Frequently Asked Questions
Why is one radiator always cold?
This is usually air trapped in the loop or a seized zone valve. We guide you through purging procedures and electrical verification of actuator heads.
The boiler fires but rapid cycles. What causes this?
Short cycling can be caused by dirt in the filter (if applicable), improper anticipator setting, or oversized equipment. We help check flow rates and delta-T.
Does this cover steam boilers?
Yes, we include specific checks for sight glass levels, pressuretrol settings, and pigtail siphon blockages common in steam systems.
