Electric Heating – SAP Regulations A Brief Outline

SAP stands for STANDARD ASSESSMENT PROCEDURE. The UK government introduced SAP to measure the carbon impact on the environment and to rate the energy efficiency of a property.  Since the introduction of SAP in 1995, there has been a number of revisions.

Revisions to the SAP criteria have taken into account advances in technology. The current SAP edition 2012 is used as part of building regulations for new dwellings in England and Wales.

You may be more familiar with Energy Performance Certificates that you get when you sell a property. These are produced by guidelines set out in SAP 2012. SAP 2012 currently don’t score electric very highly. The carbon factor used says for every kWh hour of electricity 0.519kg of CO2 is produced. This is inaccurate because it doesn’t take into account changes in our electricity grid. These inaccurate figures make an update to the SAP calculations long overdue.

SAP 10 Electric Heating Update

Electric Heating Revised for SAP 10

The new SAP 10 is due to be released this year (2019). What does this mean for electric heating?

The carbon factor for electric has now been revised from 0.519 kg of CO2 per kWh to just 0.233kg of CO2 per kWh. This is a staggering reduction. Electricity now is much closer to the calculation used for gas (0.210kg per of CO2 per kWh).

Over the coming years, we should see a further ‘Greening of the grid’. The UK aims to reduce the production of electricity from fossil fuels like coal and natural gas therefore moving to cleaner renewable energy production from solar and wind technology.

As the ‘Greening of the Grid’ continues we are likely to see further reductions in the carbon factor used for electricity. Some are already reporting that the factor in SAP 10 is outdated and electricity is even closer to gas.

Is Electric The Future For Heating?

The price of Gas is currently lower per kWh than electricity. However, we are likely to Gas prices per kWh increase because gas reserves are running low.

The cost of annual servicing and maintenance of a gas system adds up over the years. Electric heating does not carry these same costs.

A Gas system loses efficiency as the heated water travels from the boiler through the pipes and cools, therefore, you notice the last radiator on your system may feel colder to touch.

Where Is Electric Heating Winning?

  • Old night storage heaters took hours to reach temperature. The modern Elkatherm™ Electric Radiators that we supply & fit heat up in minutes, therefore, giving you a cosy home in no time.
  • ELKAtherm™ Electric Heating is 100% efficient at the point of use. You don’t lose efficiency down a pipeline as the ELKAtherm™ system is modular.
  • A modular electric heating system gives you greater control because you are able to control each zone in the property individually.
  • Our ELKAtherm™ electric radiators give great efficiency because they combine stored and direct heat. At the heart of our electric radiators is a ceramic core in which the element is directly embedded. Our Elkatherm™  heaters stay warmer for longer. Once the target temperature is reached retaining the heat in its core. This target temperature is then maintained by just topping up the heat in the radiator core. This means the heater is not constantly drawing electricity once the target temperature is achieved.
  • Elkatherm™ electric radiators are made in Germany where electric heating is more common than in the UK. The Germans have developed electric heating technology and design. Our ceramic core heaters are deeply fluted to give you comfortable naturally convected heat which doesn’t require noisy fans which use additional power and dry the air. They also give off a lovely radiated heat which is very cosy. This efficient electric heating design eliminates cold spots. In many cases, we can replace existing heating with a lower power heater.
  • Electric heating doesn’t require high levels of maintenance and servicing. Once it’s installed you don’t incur additional costs of servicing.

Electric Heating Lot 20 Controls

Lot 20 CompliantELKAtherm™ electric heating is committed to energy efficiency. All our radiators are available with a choice of Lot 20 compliant controls.

Lot 20 compliance was introduced to regulate heating controls, therefore, allowing customers to get the most out of their heating. These features include open window detection and programmable time and temperature controls.

Is Electric Heating A Viable Option For Landlords And Specifiers?

The revised carbon factor will help make electric heating a viable option for landlords. Previously even the more modern more efficient electric heaters like ELKAtherm™ made only a small impact on a property’s EPC score.

EPC is very important when looking to rent a property out. The minimum standard landlords currently have to achieve is an ‘E’.

Electric Heating A Changing Market Place

We see more and more enquiries from customers who have oil or gas heating systems. Customers often want to change to an electric heating system because they want to reduce maintenance costs. Increasingly customers are looking forward and thinking that electric is the fuel of the future, therefore, putting electric heating into the mix when looking at their next heating system.

This is a big change from being an upgrade on storage heating or panel heaters.
