How a dual-energy system works?

Higher-price indicator light

This light, installed in your house, preferably in plain view, will help you manage your use of electricity better.

It shows you which type of energy is being used for heating and so which price applies.

When the light is off, the heating system is running on electricity and you will be billed at the lower price. When it is on, the heating system is running on fuel, because the outdoor temperature is below -12°C or -15°C, as the case may be. You will be billed at the higher price.

Dual-energy meter

The dual-energy system requires a special meter that records electricity consumption at the two different prices.

There are two lights on the meter housing:

  • The green light indicates that the switch is working. it should always be on.
  • The red light indicates that the outdoor temperature is below the critical threshold of -12°C or -15°C (so you will be billed at the higher price).

Temperature sensor

The outdoor sensor sends a signal to the heating system when the temperature drops below –12°C or –15°C (depending on your climate zone).

Mode selection switch

Manual switch you can use to choose whether your heating system runs on fuel, dual energy or electricity.

To take advantages of Rate DT, you need to set the mode selection switch to dual energy. Depending on the outdoor temperature, the system automatically switches from electricity to fuel or vice-versa, whichever is more economical.

Dual-energy heating system

A dual-energy heating system usually consists of an integrated dual-energy furnace or a heat pump with a fuel-fired furnace.

A dual-energy heating system automatically switches from one heating system to the other.

An outdoor sensor sends a signal to the heating system when the temperature drops below –12°C or –15°C (depending on your climate zone).
