Daft question - Fridges

[Jewellbags]

Are they better at chilling on mains or on gas or is it exactly the same ?

As the fridge will be thermostatically controlled, the different power sources will just differ in how quick the fridge cools.
IMO - Gas cools quicker.

For a multi power source water heater; that'll be different. On 240v our Truma water heater is not temperature adjustable. So then gas is quicker to heat & we can set the water temperature.

We pick 60 deg as some unconfirmed concerns with legionnaires' disease at lower temps.

Cheers - it’s our first instance of being out in the hot and the fridge , whilst ok isn’t as ice cold as when last out - on gas

Anecdotally, we reckon the motorhome fridge efficiency is more easily effected by it's door being opened and for how long, how hot the inside & outside are. Compared to the home unit
We can extend the canopy to put the fridge side in shade.
There is a thermal paste maintenance task to improve cooling efficiency of the fins. I'd like SWMBO permission to do ours but it does get cool...

edit: forgot the comparison - fixed

The cooling circuit works best at an optimum power input. Too little or too much power and the performance falls off. Then it depends on whether the electrical elements are near the optimum power, or a bit less to save power. For example, sometimes the 12V element is less power than the mains element. The gas is a whole different can of worms, with possible inefficient flue, partially blocked jet, rust in the pipe etc. When all working properly they should be all the same performance if they are the same power.

When I bought my van I noticed a 12v computer fan set up to blow air out of the upper fridge vent. Forgot all about it until half way through a hot day without EHU last week, it definitely helped the fridge cool down more on gas than it had without it.

Ours works best on gas when very hot 30+

Mine cools best (a bit cooler) on 240v than on gas. Perhaps because the gas system (burner, flue etc.) is in need of attention whereas the 240v is just a heating element that doesn't require any servicing.
On 12v it just about maintains temp whilst driving.

If it’s hot I put the fridge fans on

Definitely worth fitting a couple of extractor fans in top fridge vent there is a kit available if you dont want to make a diy one? It has the control box etc in the kit with mounting brackets etcthis one is a bit expensive but there are others available.

28 degrees here currently. Fridge doing ok.
