An Introduction to Gas Boilers
Gas boilers are central heating systems that act like mini fires, continuously heating water. This heated water is then pumped around the property through pipes and radiators in order to heat space, and either pumped directly to taps and showers (as…
Waste Water Heat Recovery Systems
What is a WWHRS and how does it work? Typically, a waste water heat recovery system works by extracting the heat from the water your shower or bath sends down the drain. This heat is used to warm the incoming…
Flue Gas Heat Recovery Systems
How do flue gas heat recovery systems work? Flue Gas Heat Recovery Systems (FGHRS) take advantage of heat within waste flue gases resulting from the combustion of gas in your boiler. This recovered heat is used to preheat the cold water…
Introduction to heating controls
Heating controls are key to helping saving money once you have installed other energy efficiency measures such as loft or wall insulation.
Introduction to Hot Water Cylinders
There are two types of hot water cylinders found in homes today. The newer pressurised unvented hot water tanks and the older style vented hot water tanks. Unvented hot water cylinders Unvented hot water cylinders were only made legal in…
Regular Boiler
A regular boiler uses works in conjunction with a hot water storage cylinder and 2 cold water top up tanks to provide central heating and hot water.
Combi Boilers
A combi boiler heats water straight from the mains using a heat exchanger, providing hot water on demand, with an efficiency rating of over 90%.
System Boilers
System boilers heat water directly from the mains and then store it in a tank, this allows it to be tapped at multiple sources without any pressure loss.
CHP Boilers
CHP Boilers produce both heat & electricity in one single process. Find more info here on benefits, costs & current models for the home.
