OVO and Glen Dimplex Heating & Ventilation announce partnership to drive the decarbonisation of heating

28 February 2019

OVO today announces its partnership between Kaluza, our intelligent technology business, with Glen Dimplex Heating and Ventilation, the world’s largest manufacturer of electrical heating appliances.

  • As part of a series of strategic partnerships, OVO will join forces with Glen Dimplex Heating & Ventilation, the world’s largest manufacturer of electrical heating appliances.
  • The partnership involves the integration of Kaluza, OVO’s intelligent energy platform, with Dimplex Quantum high heat retention storage heaters to unlock in-built flexibility and shift consumption.
  • Overcoming the challenge of decarbonising heat is crucial if the UK is to reduce its carbon emissions. Previous analysis by Imperial College London and OVO found that smart electric heat could reduce the cost of decarbonising heat by up to £3.9billion a year.

London, Thursday 28th February 2019 – OVO today announces its partnership between Kaluza, our intelligent technology business, with Glen Dimplex Heating and Ventilation, the world’s largest manufacturer of electrical heating appliances. Delivering on its ambitions to drive the decarbonisation of heat and transport, the announcement marks one in a series of upcoming partnerships for OVO with industry leading hardware manufacturers.

The electrification of heat is one of the biggest challenges facing the UK in its efforts to decarbonise. Heating in the UK is responsible 25% of emissions.

There are 1.7m homes with electric storage heating in the UK, representing a combined peak capacity of 12GW, representing the largest grid-connected storage asset in the UK. The ability to use this capacity intelligently, as a flexible energy source, can lower the cost of electrification. This is because more efficient use of energy through storage at times of excess generation reduces the need for back-up generation and excess investment to reinforce and expand the energy network. Analysis by Imperial College London has shown that using flexible smart electric heat could cut the cost of decarbonisation by £3.9 billion a year, amounting to approximately £394 per participating household per year.

In the UK, Dimplex is the market leader in electric storage heat with a 90% market share. This partnership will allow OVO’s intelligent energy platform Kaluza, to unlock the flexibility in Dimplex’s Quantum high heat retention storage heaters. Kaluza is a highly scalable technology that has the potential to aggregate limitless numbers of storage devices – such as electric heaters, in-home batteries and electric vehicles – to produce an enormous amount of flexible load.

Through the partnership, Dimplex Quantum high heat retention storage heaters and Dimplex Q-Rad electric radiators will be made available for customers to purchase directly through the OVO Energy website. This includes scheduling an electrician to install the heater and the removal and disposal of old heaters.

Stephen Fitzpatrick, CEO and Founder, OVO said:

“Renewable energy is rapidly transforming the power sector, but the way we heat our homes hasn’t changed in decades. Decarbonising heat is an enormously complex challenge that will require technology innovation, new regulation and creative partnerships.

“We are delighted that Kaluza is partnering with Glen Dimplex, the market leaders in electric heating, and combine our technologies to take a significant step forward to decarbonising heat.”

Steven Mortimer, Chief Commercial Officer, Glen Dimplex Heating & Ventilation, said:

“Our innovative Dimplex Quantum off-peak heating system was the first product to be categorised as a high heat retention storage heater in SAP (Standard Assessment Procedure), representing a new generation of storage technology with enhanced control, lower running costs and greater flexibility than conventional storage heating.

“Now, through this strategic partnership with OVO and the integration of Kaluza, users can enjoy additional benefits whilst facilitating new opportunities to unlock the potential of lower carbon electric heating to support the Government’s decarbonisation goal.”


Notes to Editors

Electric heating needs to play a larger role in the UK’s decarbonisation of heat because it is increasingly lower-carbon. It is now lower carbon intensity than gas heating, and this trend is likely to continue. The Committee on Climate Change (CCC) has advised phasing out gas heating from UK homes. Smart electric heat represents a cost effective alternative to gas boilers.
