Smart control for boilers and electric water heaters

Always hot water, fewer high-price peaks

A water heater is a textbook example of flexible load. You want hot water at all times, but it does not matter exactly when the tank heats up. That makes it a perfect match for Leafy Energy tariffs.

Typical settings

• Minimum water temperature (for example 55°C for safety).
• Maximum total heating time per day.
• Allowed time windows (for example avoiding daytime high-load periods).

Example logic

1. Leafy analyses the next 24 hours of prices.
2. The water heater is scheduled into the cheapest price blocks.
3. Only if comfort is at risk (temperature too low) may it run outside those windows.

In demos, this use case clearly shows how many hours have been shifted into low-price periods and how much that saves on an annual basis.
