On start-up, you occasionally will smell the unspent diesel as the unit heats so that the diesel can ignite. If you are planning to travel at altitudes of 2000m or more, consider upgrading this model with the high altitude ready kit. If you’re planning to travel to higher altitudes of 3000m plus I would recommend choosing the AT EVO 40, again with the high altitude ready kit. If your system is built from components e.g.; supply tank with submersion heating element, filters, expansion tank… it will also include a water pump. This is the most important factor to consider. You need to buy the right sized heater to fit your van. If you have a small van such as a VW transporter, a 2KW heater will be fine. This will be able to heat the van whilst running at a low output. Having hot water for your caravan is one of life’s simple pleasures. Whether you want hot water for showers or washing up, a caravan hot water system is an investment you’ll be happy you made.
