So a 3-way will work on a permanent basis at home running on 240V?
And they are available with the 2 chambers... hmmm
Now, how long would one last? I know the friends we went camping with have had their engel fridge for over 10 years and it's still working like a charm - could I expect a similar lifespan out of a 3-way or are they just not as good as the compressor models?
While no problem running a3way @ home of 240v they are power hungry & you would not like the size of your bill .
Life could be excellant as there are no moving parts or electronics to wear burn out only a heater.
What you realy need to consider VERY CAREFULLY before deciding is a number of factors [some already mentioned] With regards to 2ways 12/240v
#1 how long do you expect to camp away from power without recharging your batteries ?
#2 What capacity aux bats have you got /prepared to get & where do you install them?
#3 What means of recharging aux bats do you have . Genny can be expensive to run ,not always welcomed by others, & actually banned in many nat parks.Genny alone wil not charge the battery ,you would need a charger as well.
#4 what is the expected ambient temp @ the fridge[ winter or summer camping]? The higher the ambient temp the more the fridge has to run.
#5 @ what temps do you want to run the fridge,the colder it's set the more it has to run
#6 How heavily & how often are you going to load it with new ,warm/hot goodies ? /
#7 How often & for how long is the door going to be opened each day.?
Many will tell you "we have run our !~#%^*frig & never had a flat bat ,or "we have run it for xdays etc& etc BUT do not give you the essential FACTS OF HOW THEY USE IT.
A 2 wayon12v can use from 20 to 90amphrs per day depending on how it is used !!!
I have had both for 30 years ,we regularly stay camped in the one spot [ no driving for 1to2 weeks] I have 200watts of solar panels with which I can track the sun to get max output ,200amphrs of aux battery .Also have a 350w battery charging genny. WE have a 40lt Engal ,30yrs old never any trouble,which we use as a freezer set @ approx-16c.we also have Chescold 3way[with small freezer section] which is used for initial freezing space when stocking up & for general frig use, set @ about 3c
On many occassions I have had to run the small genny or shift freezer stuff from the Engal to the 3way when bad weather has hit.
THE 3way is ALWAYS READY & WORKING AS LONG AS WE HAVE GAS.
THe older 3ways do have problems coping with temps above about 38c but the problem with most is incorrect wiring & very poor rear ventilation.
Correctly installed & with good air flow over the condensor to keep it cool [ small fan & suitable baffles make a BIG diffrerance, they will still freeze THIS is true when on 12v , IF the wiring is adequate to ensure they get a min of 11.75v@ their terminals while operating THEY WILL FREEZE
They must always be operated level ,out of level[except when travelling can do permanant damage. They will also quickly flatten bat if left on with no charge from engine atso should be fitted with either an ignition switched relay or a fridge switch which is a motion detector & switchs it off when movement stops.
IF you are buying new 3way make sure you get a genuine TROPIC RATED MODEL these are designed to cope with over 40c
I would not go anywhere for long term fixed camping without a 3way
