Stus-List Re: Remove the Red Dot?
I would likely do the opposite. The heat is “free”, it would go overboard otherwise and the Wallas heater may one day be off at the shop getting fixed. I have been off and on planning something like that for my boat, but step 1 is converting RWC to FWC and that turned out to be more involved than I thought. Increasing the running temperature of the engine caused fuel pressure issues that I assume are vapor lock, so I went back to RWC for the time being while I get around to fixing that.

I see you're also in the PNW, so I would say the decision should be based on how much cold weather sailing you do, and how much of that is motoring. We do very little motoring, and are usually not too concerned about warming the cabin when we are underway, so it doesn't make sense for us. The Wallas is very efficient, both on electrical and fuel usage, so if it were me, I'd remove the coolant heater (often called a bus heater). We have an Espar D2 forced air that we use once we are at anchor which works pretty well - we were out for 5 days last week, and we are hoping to head out for a few days this week. -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto On Mon, Feb 1, 2021 at 2:30 PM CHARLES SCHEAFFER via CnC-List < cnc-list@cnc-list.com> wrote: > I'd remove anything that doesn't work and remove it's piping too, so you > don't have to worry about future leaks.

I would have a hard time removing one of those heaters that was already in, the installation is most of the equation. There is not much to them, a couple hoses, heat exchanger, and fan – you should be able to fix/replace that if it is the only problem. As far as the hoses, for something that important, I would replace with heavy duty hydraulic type hoses with flare type fittings, then you can forget about them. That is what goes to my hot water tank, I like not having to think about them. Something like 75 – 80 % of the fuel you burn in your engine is wasted in heat, might as well re-coup it in that cool NW.

As I install our new Wallas heater, I’m thinking of removing the original Red Dot that was wire cut by the PO—may need a new fan. At one point, I think it leaked coolant into the settee cavity. Cleaned up the spill and tightened hoses after we got the boat. I realize this heater offers steady “free” cabin heat while the engine is running, but with the new heater properly ducted, not sure if reviving the Red Dot is worth the effort. Removing leakage points and making a little space is appealing. If you have coolant plumbed heater, do you use it? I’m assuming a coolant bypass is needed at the engine (Yanmar 3H 27).
