This guarantees that the heater consumes the least amount of energy.
Step 4: Set Daytime Temperature Caps
Keep daytime heat at:
- 18–19°C while at home
- 16–17°C when away
This avoids expensive peak-time heating.
Step 5: Use Smart Thermostats
Pair your smart heater with:
- Tado

Best Practices to Save Energy Using Economy 7 & Smart Meters
Using smart heaters and switching to an Economy 7 tariff is only half the story; the true savings come from making clever use of them. These suggestions can help you reduce your power cost considerably, minimize peak demand throughout the day, and heat more effectively at night.
1. Avoid Heating Unoccupied Rooms
Zonal heating, which only heats the areas you really use, is one of the biggest benefits of smart heaters.The majority of households in the UK waste significant power by heating every room, even when it’s not in use.
Why this is cost-effective
- The economy Electricity is expensive during the day.
- Your heating expenses might quadruple if you heat a room you don’t use.
- Precise control, room by room, is possible with smart heaters.
How to accomplish this effectively
- Make distinct timetables for every room.
- Turn off the heater in places that are rarely used, such guest rooms or spare rooms.
- Use the smart heater app to determine which rooms consume the most energy, then make the appropriate changes.
2. Don’t Overheat Overnight
Overheating is a common mistake, despite the temptation to turn up the heat during cheap off-peak hours.
Why this wastes energy
- Heating temperatures exceeding 20 to 21 degrees Celsius result in needless power use.
- When the heater is turned off, rooms that grow too hot quickly lose heat.
- You are paying more for no added comfort.
What temperature should you choose? (these temperatures are average user preference and are subjected to personal requirements and liking)
- 19–21°C is ideal for bedrooms and living spaces.
- 18–19°C for hallways and bathrooms.
- 16–17°C for unoccupied rooms (to prevent dampness).
Your heater calculates how long it will take to reach the desired temperature without wasting energy when you select Eco Mode or Adaptive Start.
3. Use thermal curtains
One of the least expensive modifications that significantly increases energy efficiency is thermal curtains.
Why they help
- Heat from electric heating is rapidly lost through windows.
- Heat is kept inside by the barrier created by thermal curtains.
- They can cut down on heat loss by up to 25%.
How to use them properly
- To allow the sun to naturally warm the space during the day, keep the drapes open.
- To retain heat, close them as soon as the sun sets.
- Make sure there are no spaces between them and the full window area.
Thermal curtains may significantly improve an apartment with outdated single-pane windows.
4. Install Door Draft Stoppers
In UK houses, especially older ones, drafts are one of the main reasons for heat loss.
Why this matters with Economy 7
Your house will cool more quickly throughout the day if warm air escapes from your rooms, which will make you feel chilly earlier and entice you to put on the costly midday heating.
What draft stoppers do
- Seal gaps under doors
- Prevent cold air from entering
- Keep warm air locked inside
Types you can use
- Adhesive foam strips
- Weighted fabric door snakes
- Rubber door seals
- Brush draft excluders
5. Monitor Your Smart Meter Daily
Smart meters are a real-time feedback tool that may assist you quickly reduce expenses, not only for reading bills.
Why monitoring matters
- You can view the precise amount of power used by each heater.
- Peak-time use spikes are detectable.
- You discover which appliances are “energy vampires.”
- Instead of speculating, you modify habits based on actual evidence.
What to monitor
- Your off-peak consumption each night (should be the largest percentage of the total).
- Your units during the day (should decrease with time).
- All unexpected surges caused by appliances like fan heaters, kettles, and tumble dryers.
Daily routine (30 seconds)
- Examine your use graph for the previous twenty-four hours.
- Determine any unforeseen peak-time activities.
- Examine the heaters that operated longer than anticipated.
- If necessary, modify the timetable for tomorrow.
This simple habit can easily save £20–£40 per month.
Common Mistakes People Make, and How to Avoid Them
- Mistake 1: Overheating During the Day
Heavy heating should always be saved for low-cost hours.
- Mistake 2: Not Knowing Their Off-Peak Hours
Every supplier is different; confirm yours.
- Mistake 3: Using Non-Efficient Heaters
Oil radiators and fan heaters cost more.
- Mistake 4: Not Using Schedules
Manual control wastes electricity.
- Mistake 5: Poor Insulation
Heat escapes quickly and increases cost.
- Mistake 6: Using Smart Heaters Without Smart Meters
You miss out on real-time cost monitoring

Is an Economy 7 Tariff Worth It?
How much power you can actually shift into the cheap nighttime period will determine if an Economy 7 rate is worth it. On average, Economy 7 will save you money if at least 30–40% of your total electricity use happens overnight when prices are much lower. Those residing in either an electric-only house or apartment where heating is provided only by electric radiators, storage heaters, or smart panel heaters will benefit greatly from this. Economy 7 frequently leads to far lower tariffs if you use more electric heaters, switch on appliances like dishwashers and washing machines at night, and you have a house which keeps heat in well, due to new windows or high insulation.
If most of your power use is during the day, for example, if you are a regular cook, you work from home, are home all day, and/or rely on electric heating during peak hours, then the higher daytime rate may negate any savings you get at night. If you’re not very strict with your heating schedule, Economy 7 could end up costing you more in these cases. According to us, the optimum efficiency of the tariff is observed when it is coupled with smart meters, smart heaters, and an intelligent off-peak heating plan. If your lifestyle does not enable you to alter your consumption, a standard fixed rate may be the better option.
In short
Yes, provided that you are able to consume at least 30–40% electricity at night.
You’ll gain from:
- You make use of many electric warmers.
- Your apartment is powered only by electricity.
- Your home is well-insulated, you use storage or panel heaters, and you operate big appliances at night.
And it will be a guaranteed NO:
- If you consume more electricity during the day.
- Daytime prices may be higher if you are unable to change your electricity usage.
