Personal story:

Hello
I’d like to start by saying that our house is in no way a Grand Design or early eco build project – just a three bed semi built during the 1930s, located in south east London and on a hill. We are a wife and husband who have been considering the prospects of retirement on a fixed income and making the house efficient and eco-friendly along the way.

Motivations:

Cold. When we moved into the house twenty seven years back we had solid brick walls with no insulation. Windows and doors were single pane and wood framed. The loft was an empty void with no insulation. All floors were pine with strong draughts on the ground floor and the front door didn’t fit very well with the frame.

Property background:

Built in 1933, typical three bed with separate first floor bath & toilet with a water tank in the loft. Front door opens into the hall way leading to two reception rooms and kitchen with double doors at rear leading to paved patio and 140 foot garden. Upstairs three bedrooms, bath and toilet with an electric hot water cylinder. The front of the house is south east facing with a small front garden and steps leading up from the road. Free standing garage at rear of garden. Private access road from main road leading to  rear of garden. The house is located in south east London on a hill with the side of the property exposed to wind. The reception rooms each had a gas fire located in an old fire place. Upstairs bedrooms and bathroom each had a radiator. No heating in the hall way or landing.

Key changes made:

  1. Underfloor heating
  2. Wood burning stove
  3. Loft conversion
  4. Unvented gas heated Heatrae Sadia megaflo
  5. Insulated floors
  6. Double glazing
  7. Greenstar 18i condensing boiler
  8. External Wall Insulation
  9. Solar PV

Full details of measures installed

Underfloor heating installed back in the mid 1990s on the ground and first floor with individual thermostats in each room running from a master control. The system was German in origin, Wirsbro.  Underfloor later extended into the loft conversion.

The wood burning stove is in the front living room and in the early years saved us during the coldest of winters. It is a Charnwood 6 and we use logs from local tree surgeons who are happy to donate.

The loft was converted to a bedroom and bathroom. Insulation used 75mm celotex in the ceiling and party wall space and rolled fibre insulation for the pitched roof rafter space alongside silver foil insulation for stud wall storage fixing. The conversion had underfloor heating and all house thermostats were changed to radio linked. Velux double glazed at front, Swedish Timber Product double and triple glazed windows and doors at rear.

Because of the change of use for the loft the existing water storage tank had no home so an unvented system was installed in the first floor bathroom in place of the electric storage cylinder.

Double glazing installed by a local company – upvc frames with pilkington glass.

The Greenstar 18i boiler replaced an old Potterton profile 80-e along with a powerflush on installation. Work carried out by local company, AC Wilgar.

The external wall insulation was installed under the ECO obligation and the available  grant made this possible. The MCS accredited installer (Make My Home Green) used Knauf 100mm breathable mineral wool over the entire outside with a finished render in blue.

The solar PV was installed by Sogosolar, (MCS accredited) using a product  produced in France by IRFTS. The ground mounted system combines covered car park space with solar panels and located at the rear of the garden. Besides giving a peak output of 4kW we have produced a covered area which will be used for various garden storage and summer activities.

Measures installed in detail:

  • Condensing boiler
  • Double Glazing
  • EWI
  • Floor insulation
  • Rain barrels
  • Roof insulation
  • Solar panels
  • Underfloor heating
  • Unvented hot water cylinder
  • Wood burning stove
Benefits of work carried out:

We now have an eighty year old house that is finally warm and more energy efficient – long time coming I must say.

Favourite feature:

Our favourite feature would be the external wall insulation.  It has allowed other installed features to come into their own. The heat loss through the outside walls was heartbreaking and we could never get the house comfortable in winter. When you are younger a cold environment is a discomfort but manageable but as we have got older it takes a bigger toll on both mental and physical well being. The financial savings are also very welcome.
