There is no pilot in the typical RV propane fridge. The start is by a piezo.

RE: Propane Refrigerator

I'm not going to get into an argument over it. Here is a link to the ABYC propane requirements for boats:

http://www.abycinc.org/committees/A-01.pdf

I don't think installing a propane system and/or propane refrigerator is a DIY project for most people if you value your safety. It's pretty complicated and several safety systems are required.

I have a factory installed ABYC compliant propane system and stove/oven on my boat and I'm comfortable with it, but the propane is only "on" when the stove is in use and a switch shuts it off outside the boat when it's not being used. A propane refrigerator would not be able to have this safety feature.

I have an AC/DC refrigerator and I am satisfied with it considering the size. It will freeze things in the refrigerator seciton if set too cold. No problem with not getting cold enough. It's Nova Kool.

RE: Propane Refrigerator

Does an AC/DC fridge automatically switch power sources?

*On my Norcold it does as long as both are turned on.* It runs on 120V but if the 120V goes off it then goes to the 12V source. But the 12V breaker needs to be on of course.

I would think all of the new ones do.* But can't say for sure.

*Our one year old Novacool also switches automatically.

RE: Propane Refrigerator

My AC/DC Norcold (installed by a former owner), was really just an AC, but had a built in inverter for running on DC. That inversion accounted for a huge power grab when running on DC. I put a meter on it and measured 8.5 amps consumption on DC, and it ran about 1/2 the time.
I now have a DC (Danfoss) that draws 2.7 amps, and runs less than the old AC/DC did. That change allowed me to reduce battery bank size to 1/2 what I had before. For my money, DC is the only way to go.
Just a consideration.

The modern units like the Danfloss are the best in terms of minimal electric use.

AS the unit is small in capacity , and most folks operate very few hours , the cold plate style is not worth the space in the cold box.

A State of Charge ( SOC) meter is a great addition to any DC system for the non marina cruisers.

For the real dedicated cruiser , perhaps with a mechanical compressor , the ability to custom build a reefer and only need BIG power every 3rd or 4th day , it is a very different decision.

What price silence (and the associated lack of fuel and maint) ?

RE: Propane Refrigerator

Guru,

You asked about the Vitrifrigo. It was special ordered through Sure Marine in Seattle. My wife made the purchase. I think it's 4 cubic feet of volume (small freezer above with good size refrigerator.)*Like most modern refrigerators, it consumes less power than older models (4.5 amps), is well insulated, and has an auto switch feature that self selects between AC and DC. The default mode is 120V AC. It's been running 24/7 since July 2007, with no complaints from the Admiral!

*Bump*

Any further thoughts/developments since 2011 in the world of propane refrigeration?

None that I've seen, but I also haven't been watching. I think since none of the previously existing products meet the "sealed combustion chamber" requirement in ABYC, few people are likely to use them in boats, and it's just too small a market to design something new and expect customers to deal with the direct venting requirements.

Just checked our brand new insurers policy, and propane refrigerators were the only propane appliance/item singled out for exclusion. Oh well...the 20% saved on boat insurance with the new company will easily pay for the diesel to charge up the batteries

Will still scour about for more modern/efficient solutions so we can stay out longer...

Murry,

My experience the last couple of years leans me towards a 250/300 Watt solar arrray with wheel chair AGM batts running a fridge/freezer. That comes from real-time experience with similar installed in a van that has run off-line for 2 years, beer was always cold.

I want what you want too, frozen/fresh choices up to the end of your Island next summer without listening to a genny, so that I might extend my visit to your wonderful/bountiful country!

Gas/12v/220v, perhaps they have U. S. A model for the 110v.

I just replaced my 2 way Norcold. Also often called a "not cold" with a whirlpool that fit same location. Norcold replacement cost $1,500. Whirlpool $300 ant it works excellent. I added a point of use inverter to the old dc power connection.
