I'll be honest--when it comes to staying warm on a boat, we've been spoiled! In our previous boat, the Willard, we installed a Kabola diesel furnace that gave us ten years of trouble free warmth, whether we were tied to the dock or anchored in a remote Alaska bay. The Kabola is a continuous-duty hydronic diesel furnace made in the Netherlands where they're used in canal boats and all manner of recreational and commercial vessels. Unfortunately, they are also expensive, but you know how the saying goes..."you get what you pay for". Our new Selene came equipped with an inferior heater that blew hot air into only two areas of the boat, the saloon and one of the two bathrooms below decks. Even after hours of running, the boat was cold and clammy, and the master stateroom was nothing less than freezing in March. This new hydronic system will circulate hot water via pex tubing that snakes throughout the boat's interior and deliver toasty warm air to all the living spaces in the boat. The furnace also provides hot water for showers and for doing the dishes.
'The Kabola HR-E 400 delivers over 45,000 Btu of continuous heat from diesel fuel. It is so efficient you can put your hand at the exhaust and only feel warm air. The old unit produced exhaust temperatures reaching 800 degrees...hot enough to melt the gel coat on your friend's boat when rafting up!
A basket of snakes? The new HWH uses stainless steel flex hoses to connect the heat exchanger with the rest of the hydronic system, providing "free" engine heat when underway.
Matt installing the manifold that will distribute hot water from the Kabola furnace to two separate loops that will deliver hot water to the various air handlers located throughout the boat.
This is one of the five air handlers we installed. Hot water passes through the radiator cores and when heat is called for by the thermostat, a "muffin" type fan starts up and blows warm air into the living space. The fan has two speeds; whisper-quiet on low and fast heating on high.
While we had the boat torn apart, we also replaced the 13 year old water heater with a high efficiency tank containing dual copper coils, and installed a heat exchanger to deliver waste heat from the engine to warm the boat when we're cruising.
After years of using fans and towels to wipe down wet windows, we opted to add defrosters in the pilothouse. We haven't had reason to use them yet, but we will soon enough.
Yes indeed! A towel warmer to go along with our new boat's luxurious bath tub that Gwen will surely enjoy. The rack radiates enough heat to warm the master bath and the adjacent companion way.
We're Richard and Gwen (aka, Captain n' Cook) active boaters since moving to Seattle from Los Angeles in the early 90s. In that time we've owned several interesting vessels, but this blog will record our travels on MV Kika, a 2003 Selene 47 Ocean Trawler.
