HOW DOES A COMBI & REGUALR BOILER WORK
When you turn a hot tap on, your boiler fires up to heat water and a valve is opened to send the water out through a network of pipes. A combi boiler will usually need to pause from heating the central heating water for your radiators while it’s heating the hot water for your tap, because they often can’t supply enough heat to supply to both at the same time. For this reason, you might hear your boiler switching on and off when you run a hot water tap even if they’re already lit to power the central heating.


The boiler fires up by igniting its fuel, usually gas or oil. The heat exchanger warms up the water. A pump transports the water to the hot water storage tank for use throughout the day. When you set your thermostat, the hot water moves to through your radiators, emitting its heat energy to warm up the room. The hot water is also directed to water outlets in your bathroom and kitchen when you turn on a tap.
WHAT IS THE ENERGY COMPANY OBLIGATION (ECO)?
Like CERT and CESP before it, the energy company obligation legally requires the energy companies to help improve the energy efficiency of some of their customers’ homes across the UK, thereby reducing carbon emissions and cutting energy bills. A win-win situation.
The first run of ECO ended March 2015, and a newer, more inclusive version of the programme commenced 1 April 2015 and will run until 31 March 2017.


Carbon Emissions Obligation targets all UK homes
Carbon Saving Community Obligation targets areas of low income and deprived rural areas
Home Heat Cost Reduction Obligation targets low income areas and vulnerable homes
The government estimates that the ECO deal will help thousands of households across the country with their energy efficiency, with up to 230,000 households on lower incomes benefiting, as well as others eligible for other components of the scheme.
