The Infrared Eco Electric Heating System and EPC check.
Unfortunately, as long as the SAP data based is not updated (still based on SAP2012) the EPC check for Infrared Heating System is still not available. With the new EPC regulations requiring properties to be rated E or above, there is a need for the formulas used by EPC assessors to change regarding the use of Infrared heating. At the moment Infrared Heating System is regarded the same as an ordinary electric system even though is much more effective and more importantly more efficient in comfort level heating.
SAP Assessments on the energy and environmental performance of dwellings are currently based on SAP2012 methodology which uses out of date criteria to assess the impact of electric heating on building design. Significant changes to SAP have been published, with the proposed introduction of SAP10 later in 2019/20, which will update this methodology and ensure it reflects the greening of the grid and the growing use of renewable energy.
SAP quantifies a dwelling’s performance in terms of:
energy use per unit floor area
a fuel-cost-based energy efficiency rating (the SAP Rating) and emissions of CO2 (the Environmental Impact Rating)
These indicators are based on estimates of annual energy consumption for the provision of space heating, domestic hot water, lighting and ventilation. Other SAP outputs include an estimate of appliance energy use, the potential for overheating in summer and the resultant cooling load
The SAP result is a measure of the actual DER (Dwelling Emissions Rate) against a TER (Target Emissions Rate) expressed as Kg of CO2 per m2 per annum.
SAP works on a range of baseline measures, and in the case of heating, mains gas is used as the baseline. In real terms, using mains gas for heating makes an SAP pass easier at present, because SAP2012 applies lower CO2 emissions from a gas central heating system (216g CO2/kWh) than electric (519g CO2/kWh). However, these emissions factors are out of date, no longer accurate, and are due to be updated in SAP10.
Changes to the electricity-related CO2 emissions in SAP10 are significant – reducing from 519g CO2/kWh to 233g CO2/kWh, only slightly higher than mains gas (210g).
Currently, SAP2012 assumes any electricity used in the dwelling produces 2.4 times the CO2 emissions of mains gas – this is because it uses an outdated carbon factor which does not reflect the energy mix of the UK grid.
iHelios Infrared Heating System consumes 220W per m². The system is controlled by zones which will give the user more freedom of controlling which room is heated, which means the system is more efficient.
The system could be self-efficient if backed up by solar panels. We believe the above scenario could make heating your house free (iHelios + Solar Panels).
SAP10 is a game-changer for electric heating. Because SAP2012 is weighted in favour of mains gas heating and uses an outdated and inaccurate CO2 factor for grid-supplied electricity, electric heating is essentially penalised. The same project assessed under SAP10 will improve the rating of the dwelling and more accurately reflect the energy and carbon efficiency of your home. Ultimately, homes with a higher SAP rating cost less to live in and SAP10 is likely to elevate electric heating into the mainstream.
COMPARISONS OF INSTALLATION COST
The following comparisons are based on 49 m² flat.
The cost of installation for gas central heating is £2989.30, the conventional electric heating (smart controlled) is £2545.00, iHelios infrared heating system is £1636.84 (zone controlled via mobile application).
The following is based on the cost of infrared heating with traditional heating methods for a room of 20 m³:
-Natural Gas Heating System – 90 % efficient – 45W/m³,
-Conventional Electric Heating System – 90% efficient – 45W/m³,
-Heating Oil – 90% efficient – 45W/m³,
-iHelios Infrared Heating System – 100% efficient – 25W/m³.
