Cabin Heater Installation

[Brad Cargill]

Has anyone installed a diesel fuelled parking heater in a Mac 26M? Looking for any tips / tricks. Particularly, placement of the heating unit, the thru-hull exhaust placement and part used. Thanks

Thru hulls and heat tape for exhaust are easy to find on Ebay. I have seen the China 8k ones mounted over the ports Potts. Also Under the gas tank area with the diesel fuel tank actually next to the gas tank above, and the intake and exhaust coming out the steering area.

Hi, Thanks. Not entirely sure what the port Potts is?
Intake and exhaust are supposed to be separated. Wouldn’t the engine bay be too close together??

Lets see if i can make it clearer to help,
On the X models unit inside the boat under the gas tank area aimed forward to to rear to keep sailing lean from affecting its working. with the exaust port coming out the back of the boat right in the area where the wiring and steering come out in the rudder area. Small air intake to fuel burn through can be left inside cabin or vented out the back too. The diesel fuel tank is then mounted in the gas tank area or “hole” with a very small sealed hole where the fuel goes down from the it tank down into the cabin to the unit. The fuel magnetic pump can be mounted in the cabin or outside in the tank area. The fused power wires can then be run to the steering guage area, you can hook it to the gauge power or follow the boat wiring to your batteries itself.

For the 26m you can do the above or mount it up further forward up on either of the porta-potty walls. But keep in mind the fumes my blow back into the cockpit area instead of blowing out the rear of the boat. That is why most boat have engine fumes going out the stern.

Hello,
I would like also to install a heater in my M26. Yesterday I was speaking with a MG owner, he consulted on this the Blue Water Yachts, and they recommended him to install a Wallas 1300 kerosene heater.
He is very satisfied now. He installed it on the wooden board btw the V berth and the head, with exhaust going right up and out and the fuel tank under the v berth.
Have you already installed another type of heater?
Regards

I successfully installed on in my 26M. The heating unit is mounted on the starboard wall of the afterberth. It is on a platform secured to the hull. Platform is about 10 inches high. The heater is about 1 meter from the rear. The exhaust port is thru-hull is drilled as high as possible thru the transom. The exhaust loops up to make a trap. The fuel tank is mounted of the stbd wall of the engine well. The pump mounted inside. The exhaust tube is insulated with fibreglass heat tape. No muffler installed or needed. The heat duct routed thru the stbd seat along the top edge, exiting in the dinette. Extra CO alarm installed in the aft-berth. Heat blows toward the bow. No need for extra venting to the v-berth. Extras to buy. 1.5m exhaust, proper exhaust clamps, aluminum 3″ dryer venting 6′. Thru hull exhaust port, heat tape. It works wonderfully. Totally pleased. Can send pics, to an email if wanted.
