Electric Heating Tariffs

 

At Dimplex, we are committed to helping customers get the most out of their electric heating systems - not just through adopting modern, smart technology, but also through smarter energy use and trusted partnerships.  With integrated intelligent controls and compatibility with smart tariffs, our Quantum High Heat Retention (HHR) storage heater systems are optimised to take advantage of lower-cost, off-peak electricity. This means greater efficiency, lower running costs, and a more sustainable way to heat your home.

 

What Are Energy Tariffs?

Energy tariffs define how electricity is priced. Some tariffs apply a flat rate throughout the day, while others vary prices depending on the time of use. For homes using electric heating systems, particularly storage heaters, tariff structure can significantly influence running costs.

Understanding Energy Tariffs for Electric Heating

Electric heating systems, particularly storage heaters, can operate more efficiently and cost-effectively when paired with the right electricity tariff. Some tariffs offer lower rates during specific times of day, which aligns well with how storage heaters are designed to charge and release heat.

Types of Tariffs Compatible with Storage Heating

plug

Economy 7

Offers seven hours of cheaper electricity overnight.

plug

Economy 10

Provides off-peak hours split across day and night (availability varies).

Smart Time-of-Use Tariffs

Dynamic pricing based on grid demand, typically requiring a smart meter.

Radio Teleswitching (RTS)

RTS is a legacy system used to control off-peak electricity supply for heating. Many properties with older electric heating systems rely on RTS to activate charging periods. Over the coming months, the RTS system is being phased out across the UK.

Key considerations:

  • RTS meters may need to be replaced with smart meters.
  • Without an upgrade, heating systems may not charge during off-peak periods.
  • Dimplex Quantum HHR storage heaters are designed to support modern metering systems.

Selecting a Suitable Tariff

When evaluating electricity tariffs for electric heating, relevant factors include:

  • The type of heating system installed (e.g., storage heaters)
  • The availability of off-peak charging periods
  • Metering setup (standard, RTS, or smart)

For further guidance, contact an energy supplier or use an independent comparison tool.

Smart Meters and Heating Efficiency

Smart meters enable more accurate tracking of electricity use and access to flexible tariffs. Dimplex products with programmable or smart controls can help optimise heating schedules to align with off-peak periods, supporting energy efficiency.
