3 Ways to Cut Your Water Softener Energy Bill
- 🌱
Set the regeneration to occur during off-peak hours (2–4am) when electricity is cheapest.
- 💡
Adjust the hardness setting accurately with a test kit — over-softening wastes salt and forces extra regeneration cycles.
- ⚡
Use a demand-initiated regeneration model that only regenerates when needed, rather than on a fixed timer.
Water softeners use a small motor for the valve actuator with negligible surge — the electronics draw very low, stable wattage.
