Hi Bruno We installed a bus heater (what you described) on Persistence. We already had a hot water heater so we simply had the hose that ran from the exchanger go to the bus heater and then from there to the hot water heater. No Tees of any sort. Did not affect the hot water heater adversely and works well for heating on cool fall days and for deliveries. Only issue would be that increased hose runs and number of fittings increases chance of a coolant leak at some point
The bus heater on persistence is on the forward end of the quarter berth blowing toward nav station. Layout of Frers 33 is pretty much identical to your C&C 33-2. This location also makes the bus heater close to engine and shortens the length of hos run as much as possible Mike Hoyt Persistence 1987 Frers 33 Halifax, NS www.hoytsailing.com From: CnC-List <cnc-list-boun...@cnc-list.com> On Behalf Of Bruno Lachance via CnC-List Sent: June 8, 2020 10:41 AM To: C&C List <cnc-list@cnc-list.com> Cc: Bruno Lachance <bruno_lacha...@hotmail.com> Subject: Stus-List Yanmar cooling system and water heater bypass Hi, I just remove a air heater that was nstalled by premious owner. It was T in the coolant hoses going to the water heater but never woeked well. I guess the hoses running in the bilges was too much of a heat loss. So anyways, i'm going back to original and simplicity and i remember somebody here said he added valves to have the option to "bypass" the water heater in case of a leak. Since i already have the valves and my tank is original it seems to be a good idea. My question is: can i just install them in line on each hose or do i need to add a loop before the valves with T fittings , engine side of the valves, so i still have circulation. I think it does't matter and that the engine system does not depend on this but i want to be sure. Thank you. Bruno Lachance Bécassine, 1987 33-2 New-Richmond, Qc
