Fridge Energy consumption gas (g/24h) what does this mean?

[VXman]

This is quoted for my Thetford 3 way fridge. What's does the g mean? - grammes? It says 468 so would that mean nearly half a KG per 24 hours?

Trying to work out which is cheaper at home. 4.5 KWh/24hr or 469g/24hr. (BTW My electric is 26p Kwh - day and 10pKwh night)

Yes its grams, from experience gas is cheaper.

 

[EuroTrotters]

if its Autogas, its cheaper than calor for sure

I averaged mine out to 0.5KG a day I think.

It’s about right.

 

[EuroTrotters]

What others reading have to consider is the amount of gas you are using when off grid

You can soon go through a 6kg calor using a fridge on gas. Even sooner if cooking and heating. If you have larger twin bottles or a tank, that's not too much of a worry.

It means it will consume 468 grams of gas per 24 hours.

1000 grams per kilogram
13 kilograms, or 13000 grams in a bottle.

 

[Lenny HB]

About right we use around a litre a day which is approx ½ kg. so about 80p a day on LPG, if you are using Calor it's going to be nearer £2.

Your electric cost will be £1.17 at home.

On a site with them charging commercial rates it will be far cheaper to use gas.

 

[Two on Tour]

It means it will consume 4 grams of gas per hour

How do you work that one out from 468 grams over a 24 hour period?

We use an 11kg bottle about every 10 days while away in summer, 5 days in winter. Thats all off grid cooking, fridge etc,. but we do try and use the air fryer and slow cooker as its free.

Not much in it if using refillable, but I prefer to use mains at home if just cooling the fridge down before we go away, as saves having to keep topping up when out (and we have solar so free on sunny days)

The use of 468G Per 24 hours is in an ideal situation. Without the fridge being opened and closed. Last year I had a large lithium battery bank fitted so I could move over to electric as possible. During this summer I have been using the van and the only thing on Gas was the fridge. no heating, no cooking.

My actual usage over 4 months I worked out how much gas I was using and 2 x 11KG bottles would last me 54 Days of just fridge use only. But this was also being opened and closed during the day as in the real world. The Gas was costing me 99p per litre.

So actual usage was 2 x 11kg Bottles (44 litres approx) @ 99p per litre £43.56 /54 Days = 80p Per Day

The Fridge was Domestic 8505 and was supposed to use 380g/24 hours. So the bottles should have lasted me 115 days. But in real terms it would last 54 days just using the fridge.

A bit like MPG on cars. Don't believe what the manufacturer tells you.

Just had a Thetford 2160 fitted in. Direct replacement for size and now on all electric. Not had chance to work out how many amps it is using. The the amps are free from my solar.

I think your figures are out, if you have used 2x11kg (22kg) over 54 days that's about 400g a day, so not far off the stated figures?

 

[Reevsie]

Sorry, It should have said 0.8ltr per day. not 800g per day.

It only burns gas when the fridge is actually running, the thermostat makes it cut in and out. A 6Kg bottle lasted me for well over 3 weeks running the fridge, BBq, and cooker in France one year. It was very hot and the 240v element on the fridge burnt out on our first day in France, the bottle wasn't even full but part used. The 469g/24hr quoted is accurate for the fridge running constantly for 24hrs, not normal operation.

I reckon it's about right but with external fans and an internal fan ours uses more gas, a small price for cold beer.

Interestingly in our fridge the gas is on more than it is off - even when the fridge hasn't been opened for hours.

It is LPG. I find in general usage we use about 21 litres a fortnight. Fridge/cooking/hot water. More if winter and using heating.

Anyway - this question was just about the most economical way to cool down fridge at home. We are on a good electric rate - still fixed from Sept 2021. Overnight 10p kwh. daytime 26p. so my calcs....

24 hours electric - very roughly 3 kwh at 26p = 78p 1.5 kwh at 10p =15p Total 93p plus 5% VAT 98p

24 hours LPG - 500g = 1 Litre LPG 80p

So LPG a bit cheaper for me but not a lot. If I was on a more typical electric tariff for August 2023 it would be quite a bit more than than that. Probably double the LPG price.

Our new Swift Kontiki can only fit an 11 and a 6kg refillable, 0.5kg in 24hrs is correct. Our heating is 240g an hour so we can empty 6kg in 24 hrs in the depths of winter with heating, hot water and fridge.

 

[Reevsie]

Thats one of the reasons I have fitted a diesel heater and a compressor fridge. Not just the cost, but the availability of LPG is getting harder to find. Cost me a lot upfront, but I intend to keep the van a good few years so will get the benefits of it long term.
