A little before and after photo of the install we just completed last week. The old oil boiler had a failed domestic hot water coil and needed a lot of love. We paired up a new triple pass Trio cold start boiler with a 40 gallon indirect hot water storage tank. The new system is set up with a Taco 0018e ECM circulator pump with Caleffi zone valves for maximum electrical efficiency. This circulator pump will automatically adjust its running speed based on the number of heating zones that are running.
