man either you don't use it much or you have super duper high efficiency stuff. most propane fridges will burn 100 bucks of propane in a summer by themselves.

We don't run it all the time, just when we are there (or know that we will be back in a couple days). It is not a large fridge either. But yes, it is very efficient, and always amazed just how little flame it takes to keep everything cool, incl the freezer. When you put your hand over the little chimney, you can hardly feel any heat at all. My guess it that a propane fridge would probably cost less to operate than a normal home electric one (but I could be wrong).

ahh that explains it..

very wrong, propane fridges are very expensive to run, the older ones 3 to 4lbs of propane a day, newer ones 1.5 to 2lbs a day. so even if you buy your propane at costco (cheepest you can get for portable bottles) you are looking at 30 bucks per month for the most efficient fridges, up to 70-80/month for the old style.

Hmmm, quite surprised at that, given the flame size is about the size of a pilot light on your gas water heater. And speaking of which, are you going to tell me that a gas (or propane) water heater is more expensive to run than an electric one?

I am a plumber gas water heater is cheaper not sure about a propane fridge. As for the chiller idea and efficiency I think this is the last of our worries there are so many businesses-grow ops that use the same idea on a way larger scale. Flower store needs a cool room lots of liqueur stores use them most grow ops use them legal or not I hook them up often 3/4 line straight in the unit basically a radiator with fans as water in unit heats up it dumps it right down the drain and fills back up some of these units are 6-8 feet long. Also this is part of the reason city is surrey moved to water meters 5 years ago. Not so cost efficient any more with the big units.

Hmmm, you're giving me ideas here... We have central air in our house now, and electricity costs go way up every summer. If I could stick an old car rad in the big plenum duct somehow, could maybe save a lot of money... Of course, would route the waster water out to a lawn sprinkler. We are not on water meters here in Langley. Wouldn't ever want an inspector to see that though,... LOL.

Nat gas is way cheaper than electric up to 70% cheaper, propane is about 10 to 20% cheaper than electricity. so propane a bit cheaper than electricity, now this is for heating and assumes an average of 80% efficiency, so if you have a 98% efficient furnace like me then the gas savings is even more. for water heaters the efficiency of a energy star rated storage tank type is typical 67 to 68%

when you start talking refrigeration and such different things come into play, but evaporative cooling (gas fired style fridges) are generally expensive to run, although the new ones are a lot better than the old ones.

what about running the waste to a reservoir outside and use it to water your lawn or garden?

Got my lawn watered by rain last night, was so much water almost flushed away the dirt LOL
