Night setback saves for real
A lower temperature when nobody is awake reduces heat loss, because the loss follows the difference between inside and outside.

Heating control system
A heating control system regulates temperature by room and across the day. Unlike price control, it actually reduces the number of kilowatt-hours.
See what this means for your homeThis measure is relevant if
- The house has rooms that are rarely used
- Every room is held at the same temperature all day
- The home is empty at fixed times
- You have several heat sources that do not talk to each other
What it does to energy use
Zones rather than whole house
Rooms that are not in use do not need full temperature. The effect is largest in big homes with uneven use.
Thermal mass sets the limit
A heavy house with underfloor heating cannot be lowered and raised quickly. Frequent setback then yields little, and can cost more in reheating.
Moisture needs watching
Too low a temperature over time in little-used rooms can cause condensation on cold surfaces. Setback should have a floor.
Sequence matters
Control comes after the building envelope. In a poorly insulated house the temperature drops fast when the heat is turned down, and you spend more bringing it back than you saved. The better insulated the house, the more night setback is worth.
Enova funding
Heating control on its own is not on Enova's list. The closest is their price- and load-controlled energy storage scheme, where the control is part of a system that also stores energy.
Rates and terms change. What you can receive depends on the building, how the work is carried out and which schemes apply at the time. Always check Enova's own pages before relying on a figure.
The rates tell you what you can receive. The calculation tells you what the measure actually does to your home — how much it saves, what it costs, and whether it should come before or after the others.
