House Summary

Owners: Mr and Mrs Kennedy
House Type: 1967 detached two storeys
Carbon Saving: 92%
Installed Measures:
  • 4kW solar PV with FiT
  • Solar Thermal and Biomass – Wood Pellet Boiler feeding a large well insulated Thermal Store

  • 2 x Wood burning stoves (8kw in living room – open plan to staircase so heats much of upstairs where we have no radiators; 16kw in kitchen/family area and dining room) fuelled with beech firewood  bought in bulk delivery from a local managed source
  • Assisted by full Heat Recovery Ventilation which ensures we retain the warmth but introduce fresh air
  • 9000 litre Rainwater Recovery feeding washing machine, water-saving toilets and outside taps
  • Low Energy Appliances throughout
  • Low Energy Lighting throughout (phasing out compact fluorescents for LEDs)
  • Multi-layered loft, Cavity Wall, Under-Floor, Ceiling and Acoustic Insulation

  • Personal Story:

    Ever since an A-level physics project which involved designing your own eco-home, I’ve wanted to give it a go for real. The reality was a little more challenging than the theory. The journey has involved investigating the various technologies of varying maturity, working out which suit a modernisation project on a 1960s build within a conservation area, selection of products and suppliers, navigating the technicalities of grants, reduced rate VAT and on-going commitments of FiT and biomass fuel sourcing and storage. We’re now getting towards the end of the tweaking and optimising of our setup and have three boys who are learning the benefits of sustainable living.

    • Refurbishing 1960s house, gutted, re-plumbed, re-wired and extended, so needed to replace numerous appliances and central heating anyway
    • Reduction of impact on our environment
    • Achieving practical eco-living without knocking the house down and building a passive house
    • Making this work within a conservation area
    • Saving money on running costs for the long term
    • Avoiding oil fired heating (no mains gas)
  • Property:
    • Late 1960 detached
    • Sited within conservation area
    • Village location on Herts/Bucks border
  • Measures:
    • Extended and modernised 8 years ago
    • Replaced everything but the exterior including heating system, plumbing, wiring and windows/doors

    With FiT and wood burning stoves topped up by wood pellet boiler we’re running a large detached family home on a relatively modest budget with minimal on-going impact on the environment.

    Favourite Feature:
    • Wood burning stoves – just love fire.
    • Solar pergola – favourite project so far.
