subject: Why You Should Switch To A Combi Boiler For Your Home [print this page] We spend almost 60-65% of our energy bills on boilers. Using an energy saving boiler will make a huge difference to our total energy consumption. Among the most energy efficient boilers is the combination or the combi boiler. It acts both as an efficient heater and a central heating system. Combi boilers are the most popularly used boilers in UK these days. What makes them so popular is the fact that they provide hot water instantly. Also, they do not require separate feeder and storage tanks. Because of this, it becomes compact and saves a lot of space making it easily hidden or fitted on the wall.
The working mechanism
1. When the room temperature falls below the preset temperature, the thermostat sends a signal that triggers the boiler and the heat is directed to central heating system.
2. When the heater reaches the preset room temperature, the heating stops.
3. As soon as a signal is sent when the boiler is switched on, hot water starts flowing through the tap immediately requiring almost very less time for heating.
4. Control Valves are used to divert the flow to either the central heating system or to the water circuit.
Combi boilers are most suited for small size houses which do not have a high consumption of hot water. These boilers are available in regular power output from 24KW to 34KW.
Benefits of using a combi boiler
1. Hot water is delivered instantly with no time wasted on the entire tank of water waiting to be heated.
2. Removes the need for a feeder and a storage tank thereby eliminating two major components.
3. It occupies less space because of the absence of the storage tank thereby making your lofts bigger.
4. It helps save money on installation because there are no storage tanks required which also makes for reduced expenses on pipe work.
5. Combi boilers are very easy to install and takes less time to install as well compared to conventional boilers.
6. They dont need a pump since hot water is directly inlet into the taps at main pressure.
7. They help reduce costs on electricity bills.
Things to remember before you go in for a Combi Boiler
