Hello Samschoy

Welcome to the forum.

I hope we can help but there are a few things that we need to establish first of all. It can be very difficult to diagnose a problem like this over a forum, often parts of the system needs to be checked in particular ways which obviously we cant do remotely.

I see you have an Avondale Rialto from 2002. My guess is you will have a Truma water heater, but please confirm the make and model.

You tell us the electric is "tripping" but exactly what is tripping, is the mains RCD or one of the MCB's, or is it something else?

One of the more frequent problems we do see with water heaters is a failure of the mains heating element. This will usually cause the mains RCD to trip, This element has nothing to do with the 12V system so changing the battery will not change the the symptoms. If the Mains RCD trip operates this will prevent the 12V charger from working.

Its very unlikely anything would flatten a 110AH battery over night, unless someone has tampered with the wiring,

I feel you might be best getting a mobile caravan engineer to check your systems to find what's draining your battery and and if necessary change the element on your water heater.

Ours will quite often trip if we boil a kettle or have the microwave running all at once. But I guess that is normal???!

To answer your comment, without more concise information about both the OPs and your own problems, I feel it's not possible to consider them to be the same.

In your specific case, you don't tell us which trip is deactivating. I will assume it's the MCB not the RCD, in which case it suggests that the combination of appliances you try to run at the same draws too much current causing the circuit breaker to trip.

Check the current ratings of all the appliances. Only use them in a combination where the sum of currents is less than the trip rating of the MCB protecting the circuit.

Hello again,

Again you tell us the symptoms are it "trips" But what exactly is tripping, is it the mains RCD , is it an MCB, or something else, please be specific. If you are not sure or you don't understand the question, then I doubt you will the necessary experience to repair the fault. Electrics can be dangerous so if you are not sure of what you are dealing with then do not attempt anything and as I suggested refer it to a qualified engineer.

I am not confident the information you have given us is enough to enable us to work out what is happening. I must refer you to my previous suggestion of calling on professional help who can make proper tests to establish the cause of causes of the problem.
