Seeing as the engine is an Atomic 4, taking too much heat out of a *diesel* will likely not be an issue ☺ I fully agree a hot water diesel boiler is way better than engine heat, but the cost difference is huge and I don’t have diesel fuel aboard anyway. Thanks for the info.

Calypso has a Perkins 4-108 4 cylinder diesel engine. To heat Calypso’s cabin we would have needed two heat exchangers and at least 60’ of hose. Several diesel mechanics I talked with indicated the Perkins 4-108, in typical PNW usage and 50F temp raw water did not have an over-abundance of waste heat. If the engine operating temp would not be an issue for your installation I have heard good things about the Red Hot brand of heat exchangers but I have not installed one. We chose to install a Webasto Thermo-90S diesel heater to heat its own coolant that circulates through a domestic water heater and three heat exchangers. The system is able to heat the cabin to 75F+ on winter days and provide plenty of hot water for galley or shower use. The system ran for 16 years before its first service call (last week). Changing out a burner assembly, fuel and coolant filters, and balancing the air intake and exhaust hoses was all that was needed. The Webasto T-90 is now set to provide enough heat for us to paint and cure epoxy all winter. Sure Marine in Seattle provided the parts and service and I was very satisfied. I expect they also sell engine waste heat powered heat exchangers if you are looking for professional advice.

I am converting my engine to FWC and am planning to install a cabin heater. I am wondering if anyone has done this and where they put the heater. I am not looking forward to buying 70 feet of hose, but I think having the heater forward will work better than back aft. Joe Coquina C&C 35 MK I
