What is a “combi” boiler?
A “combi” or combination boiler is a high efciency
water heater and a central heating boiler combined
within one compact unit. Water is heated directly from
the water main eliminating the need for a hot water
storage tank. Because hot water is delivered to your
taps or showers at high pressure, it’s very convenient
and can save on your hot water costs.
What is a traditional boiler?
Regular boilers – sometimes referred to as traditional or
conventional boilers – are suitable for homes that
already have a traditional heating and hot water system
that require a separate hot water tank. They are a good
option for any home where a large volume of stored hot
water is required (homes with 3 or more bathrooms, or
areas where the water pressure is low).
What is AFUE?
AFUE is a measure of how energy efcient the
appliance is in its annual fuel consumption.
Specically, AFUE is the ratio of heat output compared
to the total energy consumed by the boiler. Bosch
Greenstar 57 models have an AFUE of 96.1%, meaning
96.1% of the energy in the fuel becomes heat for the
home and the other 3.9% escapes up the chimney and
elsewhere, saving money in fuel costs over the life of
the boiler.
