My first static Caravan and first drain down for winter. Questions please if anyone can help..
1. Once drain down done can you leave Ariston Combi heating on at low temperature (5 degs) if water turned off ? Is it a sealed unit (as it hasn’t been drained) and has antifreeze in it to cope with minus 17 deg. System is on auto so again assume sensor will detect outside temp and kick heating in for radiators only and not fire up hot water ?
2. I have installed Floë 868 system so when draining down do I need to open and leave open the Caravan Drain down valves under the Caravan ? Or can they be left shut so I don’t have to crawl under to open and close ?
