Storage Capacity

The number of people traveling with you will also affect your capacity requirements because a family of five people will need a lot more water than a couple. A caravan hot water system can hold about 15 liters of water at a time. Your capacity is also concluded by the number of your onboard water tanks.

Installation And Dimensions Of The Unit

Before considering the installation of your appliance, it is important that you consider the available space for the installation along with any regulations concerning electricity or gas.

  • This feature is also affected by the installation application and whether you opt for a straight replacement of the same/different unit. Installation from the beginning if there is no pre-existing hot water system in your caravan also needs your acknowledgment. Thus, the unit’s dimension, your holding tanks, and availability for installation, plumbing, wiring, and servicing need to be considered.

Source Of Power
