    Perfect addition

    Bought for my Austrack Savannah X camper trailer as we wanted hot water for the kitchen sink. This 10L electric hot water heater was recommended to my from a friend and I’m glad I took their advice. Doesn’t take long to reach a reasonable temperature and the dual heating elements allow for flexibility at powered or unpowered sites.

    Well worth it - hot water on the go!

    This little hot water heater is brilliant. Filled with water (10lt) and brought up to temp on 240v before leaving it only consumed about 30Ah to maintain temp across a day which was easily replaced by our little 150W solar panels here each day. Plenty of water for washing and rinsing off. Great unit!
