PROJECT SUMMARY: Dimplex Quantum high heat retention night storage heaters will be installed in 65 properties. 38 properties will also receive PV, and either the Maslow battery storage (12 homes) or the Smart Energy Share (26 homes, which effectively “sends electricity next door” rather than losing it to the grid) to maximise the benefit of the PV to the tenants – this should work really well with flats (also reducing numbers of inverters required for the PV system).  The approach is to use as much of the PV electricity as possible on site, minimising what is typically ‘lost’ to the grid.   The Guinness Partnership (TGP) have c.9,000 electrically heated properties, and a plan to replace the heating in c.4,000 of these over the next 5 years.  TGP has adopted an internal target for all properties to have a SAP of 70 by 2025 – as heating installed now will still be in place in 2025, this target is part of their strategic thinking for electric heating replacements now.

The role of PV to help support new storage heating, and the role of additional supporting technology (batteries, diverters and sharers) to optimise PV so it makes a difference to tenants (not just to SAP) and delivers affordable warmth in practice is of great interest.   TGP are keen to look at how the use of the additional technology with the PV also allows us to potentially increase the size of PV arrays and deliver additional benefits to tenants. Typically larger arrays can result in a law of diminishing returns as more and more PV generated electricity just gets exported away.   The project will help to illuminate the benefits and costs of these technologies.

EVALUATION METHODOLOGY: NEA will conduct interviews with a sample of households to capture behaviours and previous energy expenditure. Thermal comfort will be assessed using thermal and humidity data loggers. Current clamps will be used to determine household electricity usage by time (day and night rate usage). The Moixa Maslow battery storage system data (PV electricity generated and amount of stored energy discharged by the battery) will be monitored, as will the Smart Energy Sharer data (PV electricity generated, amount shared with neighbouring properties, amount sent to grid). Monitoring will be 12 months and include a full winter heating period. 
PROJECT OUTCOMES:
  • This programme will provide NEA with a unique opportunity to learn how innovative technologies can help to deliver affordable warmth in electrically heated housing stock.
  • Data around the performance of Dimplex Quantum will measure how well they perform in reducing heating costs for fuel poor households.
  • The programme will examine the extent to which householders can adapt their behaviour to utilise electricity generated on site via PV and stored in batteries.

Extended TIF programme, results due summer 2018
Monitoring and evaluation of this programme will continue during the winter of 2017/2018, doing so will enhance the quality of data and enable a comprehensive evaluation to take place.
