--------------------------------------------------------------- ------------------------------------------------------------
Inexpensive to purchase and install. Cannot be used for cooling.
Easy local control in each room. Takes up living room.
In well-insulated houses, it may be cheaper than other systems. Generally less efficient than other central heating systems.
Is a combi boiler a direct or indirect system?
For hot water delivery the heat from the Primary heat exchanger is then circulated through the plate heat exchanger, which in turn indirectly(doesn't physically touch) transfers its heat to the mains water supply running through the boiler on its way to the tap. ... Thats how an Indirect Combi Boiler design works.
What is the difference between direct and indirect central heating?
Direct heating – the water is heated directly from the heat source either by an immersion heater or by the boiler. Indirect heating – the central heating and the hot water are separate. The water is heated via a coil (heat exchanger) from a boiler. ... It helps the system cope with the expansion of water in the system.
Is a combi boiler a direct central heating system?
A combination or 'combi' boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won't need a hot water storage cylinder or a cold water storage tank in the roof space.
What is a indirect central heating system?
Indirect heating – the central heating and the hot water are separate. The water is heated via a coil (heat exchanger) from a boiler. ... The heat can come from an immersion heater, directly from a boiler or indirectly from a boiler using a coil fitted inside the cylinder.
