Readers tips of the month - April 2012

Posted by Cathy Debenham on 27 April 2012 at 11:10 am

We're always keen to hear your tips about you make your homes and businesses more energy efficient - and how you get the best out of your renewable energy. Here's our favourite tips and stories from the past month.

Chemeng says: "Our PV system has reduced our annual grid electricity usage by about a third, following also replacing our windows and doors with A-rated glazing using argon fill, soft spacers and Planibel coating.

"Our annual gas usage has fallen by 40% after replacing the system boiler with a Viessman 200W with modulating burner and weather compensation and eliminating use of a single wall thermostat. Use of radiator thermostatic valves gives room by room temperature control and a much more even temperature throughout the house."

Roger20 advises: "Get an inverter that offers Bluetooth communication with a PC/laptop." (If you like data this is ideal - you can manipulate it to your heart's content.)

He adds: "Go for a panel manufacturer that will be around in 25 years time! Look carefully at T&Cs - particularly warranty/deposit protection. Be aware that the inverter will possibly/probably need to be replaced within the 25 year feed-in tariff period.

David Burton reports a noticeable improvement in temperature from cavity wall insulation. He also points out that light tunnels are very good for providing natural light where there are no windows.
