Refridgeration

If you come down to the boat every weekend, which one adds less wear and tear on your Refridgeration:
Leaving it on thru the week so it occasionally runs or turning it on Saturday so it runs continuously into Sunday and then turn it off when you leave on Sunday?

Re: Refridgeration

What are the manufacturer's recommendations for your unit?

Re: Refridgeration

Good question. I would like the answer too.

I have been leaving it on since I leave food, like staples in it. I leave a couple of bags of ice in the freezer....I had heard that freezers don't have to work so hard if they are full as opposed to just have air in there.

Re: Refridgeration

Well of course not as all the frozen whatever in a freezer is in effect ice.

Running anything with electrics(motors) from time to time keeps moisture out and is general a good idea. But adding run time to a unit for no reason might promote failure. So leaving it on a timer to turn on for an hour or two a week while unused might be a good idea but leaving it on and empty all week for no reason doesn't sound like a good idea.Thermoelecrics should be "on" 50% or less of the time if your box is properly insulated.Holding Plate types need to be fully Charged and would need a different cycle to be kept healthy I would think.

Re: Refridgeration

This has been a recurring question ever since they started making boat fridges. Some folks like their beer cold and keep mayo in the box during the week. Good luck to them. It requires keeping the boat plugged in, which is way more dangerous than keeping the fridge on and asking about longevity. Anything that is mechanical that gets used less will last longer. As far a fridges and its seals, using them regularly will help, but using them constantly when you're not there will reduce their life. As far as plugging in, we are proponents of "If you're not there, unplug." Why? Boat fires. Chargers can die. The mayo in your fridge won't smell so good if there's a power failure on your dock. The only skipper I heard who had a good reason to do so when he wasn't ON his boat was a fellow who had his office 50 yards away from his boat! How he ever got any work done... If you want cold beer on your boat when you get there, stop at a 7-11 on the way there or bring a cooler. You can buy small packages of condiments that don't require refrigeration. Regular "exercising" is good, continued use will shorten life.

Refridgeration

FYI it's not about cold beer. It's about whats best for the compressor and the fact that when you cast off for the weekend sail and anchor your fridge will put a constant load on the battery.

Re: Refridgeration

On land....the recommendation for your chest freezer is to keep it full for best efficiency. Cooling empty air space is harder than keeping frozen stuff frozen. I usually will freeze jugs of water, to keep it full, they can then also be used to keep food cold in the cooler when traveling. They also provide drinking water when they defrost.
Our fridge on the boat is 12V and runs off the batteries, solar panels and wind generator. I just wondered if cycling it on and off each week while we are in dock is worse than keeping it going.

On an intuitive level, Stu has got to be right.
OTOH, the Frigoboat system I installed about a decade ago is still working fine, and we leave it on from about March to December every season. It's sooooo nice to have cold pop, water, and even beer when we go out for a sail or a weekend.

Our boat does get visited several times a week, so it's not left unattended for long periods.

Our YC has very reliable shore power, being all new within the last decade. I guess the answer is that it "depends"....

Refridgeration

Seaquinn same here. I could run my fridge on just solar and wind when at the dock. No need to be plugged in. I just wonder what's best for my 20 yr old fridge.

Re: Refridgeration

Fridge is always stocked like at home. Stays on 24/7.

Now let's talk about the ice maker. Not having to stop at all on the way to marina is nice! I can tell if there was an extended power outage while we were gone. Cubes refreeze a bit together. Stirring them up is all the effort we need to make. If I need to do a little compressor maintenance, so be it.
