Installing an energy efficient boiler - Energy Saving Trust
Heating accounts for about 55% of what you spend in a year on energy bills so an efficient boiler makes a big difference. All well-maintained boilers burn their fuel very efficiently but they inevitably lose some heat in the hot gases that escape up the flue (a pipe for extracting fumes and supplying fresh air to the boiler).

A time delay relay is a way to squeeze the most heat out of your system without running the boiler. When the thermostat clicks on the relay causes the boiler to circulate hot water through the system without turning on the boiler. After a set time the boiler will fire up. A time delay relay costs about $100 and can cut your fuel costs by up to 10%.
