Lighting and Heating

There are various ways you can save energy on lighting and heating.

Lighting in a typical home accounts for around 16%of its electricity use. Fitting low energy light bulbs is one of the simplest ways to reduce energy waste and costs.

Energy saving light bulbs can use up to 80% less electricity than an incandescent bulb and last up to ten times longer. Continuing advances in technology mean that energy saving light bulbs are now available in a wide variety of fittings shapes and sizes.

LED ( light emitting diode) fittings are becoming more common and there are many types of LED lamps that will replace tungsten lamps.


Installing a high efficiency boiler can make a significant contribution to reducing fuel usage. Modern boilers are considerably more efficient than models even 10 years ago. An A rated boiler can produce the same amount of heat for a fifth less fuel and C02. Some of the best condensing boilers convert more than 90% of their fuel into heat whereas most boilers can only manage 75% or less. Condensing boilers differ from ordinary non- condensing boilers in that they have a second or larger heat exchanger to capture some of the heat that would otherwise be lost out of the flue.

Other forms of efficient heating such as biomass can also be considered. With biomass heating a wood burning stove and a boiler can provide both heating and hot water reducing C02 emissions by up to 90%. The C02 released by biomass is balanced by the c02 absorbed during its production.
