Entry # 152
Brief overview of the project
Replaced existing, unreliable boiler with new Viessmann boiler. Installed a Caleffi SEP4 hydraulic separator, Z-one zone valves, ZVR relay, and 573 Series AutoFill combo.
This is a boiler retrofit replacing an existing boiler with new boiler including all new accessories.
We have yet to reach a heating season, but we figure it will perform to expectations.
