Hurricane II Combi heater

Hurricane II Combi heater. If you spend time on your boat during the cold season or live aboard you need a heater. A heat pump won’t do in winter except to take some chill out of the air. Some real heat options include diesel fired heaters, propane heaters or a diesel fueled Hydronic system.

A Hydronic system utilizes water heated by a furnace and then circulated through the cabin. The water can also be used for onboard hot water requirements and hot showers. Heat from this type of system is not dry like that of a forced air heater, which dries out your skin. I grew up at home with Hydronic. A boiler/furnace heated water which circulated through radiators in the rooms.

What is a Hydronic heater

The circulation of hot water to provide heat is known as a “Hydronic” System. It is a closed system continually circulating coolant. It begins with a furnace fueled by diesel to heat the water.

A water pump circulates the hot coolant through a domestic water heater and then to the various fan units located throughout the interior.

Testimonial

Below is a testimonial sent to us from Mark Tilley of Canada, who shares his opinion of the Hurricane;

I noticed you have a page on water heaters now. You should look at the Hurricane Combi. We live aboard in Toronto so having a diesel heater that also heats our DHW is a major advantage over buying extra hydro for space heaters everywhere.

But the real plus is that it’s a 12V unit that will also heat the boat and DHW when at anchor when we’re cruising in non-tropical climates, and at a much greater efficiency that running the genset to drive an electric DHW tank. Con is price and complicated installation, which we got done professionally, but it was worth it. Mark

Hydronic V Forced Air

Hydronic Pros: Heat sink; Produces domestic hot water; Less cycling, so longer life Zone heating possible

Cons: Twice the cost of Forced Air More moving parts Difficult to draw in fresh air More humidity Noisier; Increased install time

Forced Air Pros: Drier air due to mixing fresh outside air; Lower cost; Easier install; Ducting can be used for A/C as well.

Cons: Less overall capacity; Higher cycling, shorter lifespan; Less efficient;
