Our smart hot water controls make sure you only heat the water you need

• If a house has a well-insulated water tank, our system will choose the best time to heat the water based on boiler efficiency and cost savings (often when your home is being heated).
• If a hot water tank is less well insulated, our system monitors the tank using sensors and learns when the customers use hot water and how much they need. Then, the system works out when to start heating hot water so it is ready just in time, significantly reducing the energy waste that comes from heating the same water twice.
• If people go away on holiday, they can let PassivEnergy know in advance. As well as all the other energy saving features this will trigger, Advanced Hot Water Control will stop heating their water. It will also make sure there is a full tank of hot water for when they return.
