Worcester Bosch Greenstar Boilers

Recommended by Gas Safe Central Heating Ltd.

Up to 10 Years Guarantee on new installations

To the majority of people in Britain, heating and hot water are basic everyday comforts we take for granted. We turn on a tap or shower, turn up the thermostat on a chilly evening and settle down to watch the TV.

But there is a cost to the environment

The waste gases discharged through the flues of domestic central heating boilers account for about 21%* of the UK’s total emissions of carbon dioxide, which globally is a major contributor to climate change.

Now the Government has acted to try and address the problem. Changes to Building Regulations mean that from 1st April 2005, the only kind of boiler permitted in all new and virtually all replacement domestic installations will be the high efficiency condensing type.

Good news for everyone who enjoys the luxury of convenient heating and hot water but who is also concerned about saving money, conserving non-renewable energy resources and helping the environment.
