We all want our homes to be warm, and to heat our homes as cost effectively as we can. Here are a few tips to help you do just that..
Storage heaters charge up with heat when the price of energy is cheaper. To get the most from the system:

There are two main types of system:
Make sure you control the times and temperature your electric heating system comes on and off, so you don't spend more than you have to.
These systems can provide heating and hot water to your home. Though they don't use energy to 'heat up' they still use electricity to operate. However, the amount of energy they use should be less than the amount of heat they produce.
Make sure you understand how your system works - speak to your installer if you need advice.
New electric panel heaters use gels or other heating fluids to retain heat longer than ordinary convection heaters.
These systems can cost more to operate than storage heaters as they might not always charge when off-peak energy is available. If you can control their temperature or when they come on and off, you'll be able to operate them more efficiently.
When first moving into a property, or when there has been a change to the electrically operated heating system in your home, the times at which the heating operates may require to be changed.
While the correct metering arrangement and operating times will be provided/arranged by your installer there can be occasions where this has not been done.
To help guide you through the metering arrangements we have pulled together a table of options that may be available to you. This shows the number of readings/rates on the meter and what they record and when they operate ( the switching times).
Economy 7 timings vary depending on supply area, which is why we encourage customers to contact their local meter operator to check the exact timing for their supply. The map shows timings dependant on the area you live in.
White Meter 1
Single meter

Day/Night/Control
Day rate is 08.00-23.30. Night rate is 23.30-08.00.Control rate is for storage heating and the control circuit is energised for 8.5hrs in every 24hr period.In recent winters the charge period has been split to provide 7:5hrs overnight and 1hr in the afternoon, between 12.30pm and 3.30pm. This does not apply if you are on Comfort Plus White Meter with Weathercall (see below for details.)
ComfortPlus White Meter with Weathercall (Supply area 18 only)
The recording of your energy use is as for CPWM. However, for storage heating purposes the charge provided by ScottishPower depends on the forecast temperature. The actual charge period may therefore vary depending on the forecast. If you are on the Weathercall option it is recommended that the Input setting on your storage radiator is always at the highest setting.
Comfortplus Control (Supply area 18 only)
2 x Single meter
Domestic / Control
Normal domestic appliance usage will be recorded on the Domestic meter.Heating and hot water usage will be recorded on the Control rate meter.Storage heating should form 60% of the total installed heating load. The charge provided by ScottishPower depends on the forecast temperature as Weathercall is an integral part of the tariff. The actual charge period is therefore weather dependant as described above.
Total Heating, Total Control (Supply Area 17 Only)
This is available, from ScottishPower, to customer’s living in the North of Scotland where they already have the required metering installed. This option operates as per our weathercall option with the charge to the storage radiators fluctuating depending on the weather forecast. It is recommended that the Input setting on your storage radiator is always at the highest setting.
Economy 2000 (Supply area 18 only)

Electricity for all other purposes must be taken on Domestic Tariff.The Economy 2000 supply is made available for periods at ScottishPower's discretion totalling 18 hours per day, but with the proviso that no interruption will exceed 2 hours. Typical off times are 08.00-10.00, 16.30-18.30 & 00.00-02.00. It is important, therefore, that the boiler has a sufficient thermal store to supply space (and possibly water) heating requirements for 2 hours.Direct acting boilers without storage capacity are not permitted to make use of Economy 2000.Rate 1 records daytime domestic use, Rate 2 records night time domestic use and Rate 3 is Economy 2000 and records boiler usage only.Some installations may have 2 X single rate meters i.e. 1 for domestic and 1 for Economy 2000.
