lizken Posted October 29, 2017 Share Posted October 29, 2017 Can someone tell me how the tank heaters work.are they 12v or 240v Link to comment Share on other sites More sharing options...
Keith T Posted October 29, 2017 Share Posted October 29, 2017 Can't speak for Elddis, but we have them fitted in our Autotrail 610SE PVC, as the water tanks are fitted externally underneath. The heaters are 12v, and controlled from button swtiches in one of the lockers in the van. It was suggested to us to watch for two things, pretty obvious really, though - one, only switch them on when there is water in them, and secondly, as long as there is water in them, they will only operate anyway if the temp drops below about 5c I think. Its just another of those things to remember to do, bit like switching off the solar panels when on EHU I guess.... Link to comment Share on other sites More sharing options...
pagey Posted October 29, 2017 Share Posted October 29, 2017 hi why would you switch off solar panels when on hook up? Link to comment Share on other sites More sharing options...
Keith T Posted October 29, 2017 Share Posted October 29, 2017 pagey - 2017-10-29 6:01 PM hi why would you switch off solar panels when on hook up? Its a good question - the answer is that we were advised by the dealer that this is the process to be used. Any comments on this procedure ?? we're new to Solar panels!!

lizken Posted October 29, 2017 Author Share Posted October 29, 2017 Thank s for that, but it confuses me more as the only switch O can find is on the main control panel for 'tank heaters so I cannot operate them all independantly. I will have to contact the dealer as there is no mention of tank heaters in the manual Link to comment Share on other sites More sharing options...
Charles Posted October 29, 2017 Share Posted October 29, 2017 Ours is a 2014 model accordo 105 and there is no switch for tank heaters at all. I did notice a heater element in the top of the waste water tank though when I took it off. It's certainly a 12v element because the spade connectors are uninsulated and the wires are thick singles. As to what switches them I don't know maybe a clixon type bi-metallic strip. The fresh water tank is on board so I doubt if it has a heater.

Why would one want to heat their grey water? :-S .......Have buckets not been discovered ? 8-) ....... Not that I'm polite enough to feel the need to use a bucket :D ........Currently with an open cock in Weymouth B-) ....... Link to comment Share on other sites More sharing options...

Robinhood Posted October 30, 2017 Share Posted October 30, 2017 This link may help (though it looks as though they might have gone to the extent of putting an isolation switch in circuit for yours). https://www.motorhomefun.co.uk/forum/threads/winter-pack.119827/ Link to comment Share on other sites More sharing options...

lizken Posted October 30, 2017 Author Share Posted October 30, 2017 Thanks for all replies. I think I will just stop worrying, leave the.main control panel switch off until temperatures drop to hear freezing, then drain down and then worry again.

lizken Posted October 30, 2017 Author Share Posted October 30, 2017 Not sure yet, but I think it is below the shelf storage in the wardrobe, this below the outside water filler.I would like to find the water pump, which sounds to be in the same area but I cannot find any access yet Link to comment Share on other sites More sharing options...
