The Sustainer Homes container is completely self-sufficient, the water supply, heating and electricity must be 100% self-sufficient. Especially the heating is a real energy guzzler.
Triple Solar supplies an energy system with PVT solar heatpump panels linked to a Vaillant heat pump. The batteries are charged by the PVT solar panels and two windmills of 700 Watt each.
In order to save as much energy as possible, the most energy-efficient heating system has been chosen and a regulation that ensures that the heat pump delivers energy when it has the highest efficiency.
