Insulation - Tanks and Pipes
Insulating your hot water cylinder is one of the simplest and easiest ways to save energy and money. Fitting a British Standard 'jacket' around your cylinder will cut heat loss by over 75%. If you already have a jacket fitted, check that it's at least 75mm thick. If not, it's well worth treating your old cylinder to a new winter coat.
Advantages
A new, 80mm thick hot water cylinder jacket will save you £20 per year. The jackets themselves cost about half that, meaning that you'll reclaim your initial cost in around 6 months. Insulation for hot water pipes will cost about £10 and save you around £10 a year, which means you could potentially recover the cost of fitting within a year.
Cost £20 per house
Cavity wall insulation
Cavity wall insulation is a fantastic way to significantly reduce the amount of energy you need to heat your home. The average house could reduce heating costs by 15%. In fact, between 2002 and 2005 around 800,000 households installed cavity wall insulation. It is estimated that this will have saved nearly 400,000 tonnes of CO2, enough to fill the new Wembley Stadium 47 times.
Advantages:
Easy to install, without disturbing occupants -It's a simple process and is normally completed within three hours, without damage or mess to your house or garden. Grants are available
Disadvantages:
Need to have cavity walls (houses built since 1920s). Installation may create some fumes.
Cost: £ 500.00 each / per house
Estimated annual £ saving: £ 90 Payback: 5 years
