Fitting a diesel blown air heater in a GK29

Post by Hardover » Mon Apr 09, 2018 10:23 am

Can anyone offer any advice on fitting a eberspacher type air heater into a GK29? The obvious choice would appear to be fitting the heater in the cavernous starboard cockpit locker BUT given the fact that the diesel tank AND the gas bottle are located there.........

On my Fulmar I mounted the Ebersparcher in the transom, and quite high up. All the hot air pipes have been wrapped with insulation and in places boxed in with plywood to stop any locker contents touching anything. Some photos on this page of my photo file.

Diesel does not burn easily, if you do not believe me, give it a try by dropping a match on some diesel. A diesel engine uses the compression of the air fuel mixture by 20:1to cause excess friction in the mixture to make it explode. So no need to worry about your diesel tank is nearby an installation.

Your gas bottle contains petrochemical fuel. It is pressurised to keep it liquid. When released into the atmosphere it turns to a heavier than air gas. As a safety measure the gas bottles do not drain to anywhere inside the boat. Yours is probably like mine and drains into the cockpit and then overboard by the cockpit drains. Modern boats now have to have a direct drain overboard, but both our boats were built to earlier regulations.

Thanks for that. I have a plan.......
Appreciate your comments about diesel and gas. Must have a look at the gas locker in the very near future. At the moment it's a wooden box open at one side to facilitate the cylinder and any spillage would go straight into the bilges.

That sounds extremely wrong and a bodge. Looking at the photographs of a GK29 (https://www.yachtsnet.co.uk/archives/we ... y-gk29.htm) there appears to be a gas locker just forward of the sail locker. This should hold a Camping Gaz blue bottle. In these photos I see there is a plywood box under the tiller and wonder if this might contain a larger Calor Gas bottle. If this is what you have then it will drain out of the cockpit via the cockpit drains.
