SUITABLE FOR ALMOST EVERY HOME
Please note that this product is no longer available and the information below is for reference only.
The
Celsius 25 is a fully modulating gas condensing
boiler, which is compact, flexible and is suitable
for almost any home. The Celsius 25 wall-mounted
boiler boasts dimensions of just H621 x W420
x D250mm and weighs only 38 kilograms.
Its small design means it can be sited virtually
anywhere.
The
heat exchanger is made from high quality stainless
steel and the burner is manufactured
in a specially
developed metal fibre mesh. A down-firing design
produces a low flame temperature and super low
NOX combustion. Another attractive feature is
the LED display on the boiler front, which indicates
boiler status.
ENERGY-EFFICIENCY
Celsius 25 boasts high performance
and energy-efficiency with a SEDBUK ‘A’ rating
of 90.4% and a peak efficiency of 97% when in full
condensing
mode. NOx emission levels have earned a Class 5
rating, the highest achievement under European
Standards, meaning minimal atmospheric pollutant
emission.
Heat output is automatically adjusted to suit installation
heating requirements from 7kW (23,900 Btu/h)
to
25.2kW (86,000 Btu/u) (click
here for higher output),
making the unit ideal for most domestic
applications. Optimum modulation maintains combustion
efficiency at all heating output levels. The
appliance automatically sets the heating output
required
for each individual installation up to 25.2 kW
(86,000 Btu/h), by constantly monitoring the boiler
temperature
as required by the thermostat.
For additional efficiency,
the unit monitors the water flow-rate and controls
the integral standard
domestic pump to match the pump speed to the boiler
output.
