Rinnia e 110 and a comfort air wet coil
Ok guys tell me me what you think. Have a customer that wants a combo boiler. He has forced hot air right now. So he suggested a wet coil in the air handler. He does live on the 6th floor in Hoboken. Updating gas line isn't an option. The customer has an existing furnace 100,000 btu in.
Customer and I agreed on a e-110 combi and a comfort air wet coil. Units will be within 5 feet from each other. First will it work, the boiler needs to be at high 175 degree water to make the heating btu to satisfy the load on the house. That's the reason I'm going with the boiler instead of a water heater. The reason for the e-110 instead of the 75 is for more gpm per gallon on domestic. Is this reasonable request? Secound I was looking at the diagrams for wet coil, seemed like if there wasn't a big pressure drop you don't need primary secoundary looping.
Any info is appreciated.
