2700 SE heating options

[Gleebitz]

Hi everyone

I’ve just bought a Maxum 2700 SE. I’m very pleased with it however i need to put in a heater.

My initial thought is a diesel heater is probably the best option.

Does anyone have any suggestions on where would be best to install it and where to run the exhaust pipe?

I’d also appreciate any recommendations for specific heaters.

Thanks

Dan

A ton of boaters use this. https://www.lowes.com/pd/Mr-Heater-9...ter/5001461121

Does your A/C unit only have cooling? Many of the 2700 and up boats have reverse cycle air and heat functions.

There is no air con. I’m in the UK so it’s the cold that’s the issue, not warmth.

Yeah but I’d like something that I can leave switched on below whilst I’m on the upper deck. I wouldn’t want anything with direct heat like that.

There are only 3 groups of heaters I’m aware of. Those that burn some type of fuel to produce heat, electric units and hydronic that use hot water from the engine.

Propane, diesel or solid fuel options are popular on large cruisers and or sailboats, but they do have open flame, so I don’t like them on gas powered/smaller boats. For the electric option, which is very popular, you need a genset that can support the voltage needed (120/240). The hot water is an option where a small radiator is mounted in the cabin and heat is drawn from the engine cooling lines. Free heat, but it only works when engines are running and up to temp.

After a ton of research I truly believe the example I posted above is the most economical, safe and efficient way to go.

As long as it’s not used inside the cabin, specifically says outdoor use only.

[Roc64]

Nope! I am completely comfortable using these indoors with proper venting! They have been used in Tents, Boats, RV's and homes for years. I thoroughly researched them and tests on them. I wouldn't sleep with it on just because I wouldn't need to. Some people claim different but every tests I have seen is just like this one! Showing ZERO danger! They also have an CO shutoff.

Your life it’s a combustion device that can malfunction.

so is the gas fireplace that is in 95% of all new homes that are built, not to mention gas water heaters, and furnaces. It is my life you are right, I choose not to live in fear.

Yes but they are vented to the outside!

Not in fear but wisdom.

Exactly - all those are vented to the outside and to be legal they must be.

These Mr. Heater units are clearly marked - "for outside use only".

[jparsons121]

I have used these before when camping and they do have the minimum safety features, tip over shutoff and even a O2 sensor (note it does NOT have a CO sensor mentioned in a previous post).

As they are not vented to the outside there are two factual points of consideration.
First is adequate ventilation. As the specs Buddy is consuming oxygen and is not venting outside. A port or the hatch must be open at least 9sq in min.

The other point is condensation. Burning propane produces condensation. On boats we all do what we can to reduce the moisture in the cabin. Dehumidifiers, Damp Rid, etc.
In a camping trailer, the walls literally had beads of water on them in the morning after running the heater during the night. After only a few weeks, there was mold and mildew forming.

My post and all the information shared in this thread are considerations to make and informed personal decision. Key word is informed.

Clearly says this on the Mr Buddy site. " North America's Most Popular Portable Propane Heater! This patented radiant 4,000-9,000 BTU Liquid Propane heater connects directly to a 1 lb. cylinder and is the perfect solution for heating enclosed spaces like large tents up to 225 sq. ft. With the Oxygen Depletion Sensor (ODS) and accidental tip-over safety shut-off you can be sure that you will enjoy years of comfortable Indoor safe heat" Pretty sure if it wasn't true there would be people dying like flies! Not trying to get in a pissing match. These HAVE been used by Millions of people INDOORS and they work excellent! If a person doesn't like them or are afraid to use them that is there prerogative. To each his own.
