We are mainly going to use our motor home for day trips until around February half term and were not planning to fill it with water for each day trip but leave the tank empty. I thought this would be easier as it is in a storage place and we can just drive in and drive off. However, it has only occurred to me that the boiler has an automatic thing on it (technical term, I know) which dumps the water in it when the temperature gets low. I presume the last couple of days would be low enough for this to happen?? So presumably the next time the boiler needs to go on it will need water. Will we be better putting some water in the tank for each day visit then? I am not sure what would happen to the boiler if we accidentally put it on and there was no water in it. I'd be grateful for any advice - had no idea there were so many things to think about!
