Introduction
Instant water heaters are a convenient way to enjoy hot showers anytime, but without smart usage habits, they can also add to your electricity bill. The good news is — by making a few changes, you can enjoy the same comfort while saving energy and money. Here are practical tips to save electricity with your instant water heater.
1. Choose the Right Size and Type of Heater
If your heater is too small, it will overwork. If it’s too large, it will waste electricity. Instant water heaters are already more efficient than storage heaters because they only heat water on demand, but selecting the right capacity for your household is key.
2. Optimize Your Temperature Setting
Set your instant water heater temperature between 37°C to 40°C for showers. This is warm enough for comfort but doesn’t waste extra electricity. Overheating water and then mixing it with cold water wastes energy unnecessarily.
3. Limit Shower Time
Every extra minute in the shower means more power consumption. Cutting your shower by even 2–3 minutes can lead to noticeable savings on your electricity bill.
4. Use Energy-Efficient Showerheads
Pairing your instant water heater with a low-flow showerhead reduces water use, meaning the heater works less while still providing good pressure.
5. Turn Off When Not in Use
Unlike storage heaters, instant water heaters don’t need to run all day. Turn it on only when you’re about to use it and switch it off after. This simple habit can cut unnecessary electricity usage.
6. Maintain Your Heater Regularly
A clean showerhead and well-maintained heater mean better water flow and heating efficiency. Limescale or sediment buildup forces the heater to work harder, using more electricity.
