This project was delivered by Nottingham Community Housing Association (NCHA) in collaboration with Greenvision Energy Ltd. It involved replacing 20-year old standard storage heaters with the ‘Dimplex Quantum’ high retention electric storage heaters; and replacing existing 10-year old domestic hot water (DHW) cylinders with ‘Dimplex EC Eau ECSd cylinders, with programmer and immersion. In selected properties a Voltage Power Optimiser unit – the ‘Matt:e B60 PVM’ and the ‘Owl Intuition-E TSE200-101’ wireless energy monitoring equipment were installed as proposed by the partner.
The programme had the following aims:
- To increase energy efficiency of each property via a whole house approach so that in addition to installing new technology, advice and support is given regarding no-cost and low-cost options, behavioural change and issues such as understanding bills and meters and switching.
- To assess the viability of the measures installed and if they have a place in addressing fuel poverty in the vast number of homes fitted with old storage heaters.
- To examine the impact of these products on the comfort and levels of satisfaction of the residents.
- To build an evidence base on the viability of these technologies to advise others on similar action on affordable warmth.
