Wall Hung Condensing Boiler Range
Vortex Wall Hung Condensing Boiler RangeThe launch of Grant’s
first wall hung oil-fired boiler range comprising two indoor and
two outdoor SEDBUK ‘A’ rated models, is an exciting addition to
the Vortex family. Available in outputs ranging from 40,000 –
70,000 Btu/hr in open vented system versions, the new appliances encompass Grant’s patented Vortex stainless steel heat exchanger
and turbulator baffle system.
All Indoor wall hung models require a separate flue kit (not supplied
with the boiler) and are compatible with all Grant EZ-Fit low level,
high level and vertical flue systems, so now almost any installation situation can be catered for.
All Outdoor wall hung modules come complete with a factory fitted
flue, high quality external powder coated paint finish, built-in boiler
frost protection, mains isolating switch and a test switch.



SEDBUK/HARP BAND ‘A’ – EFFICIENCY: 93.8 – 94.9% GROSS
Ecoflam MAX1 Burner
1 Year guarantee
Whisper quiet in operation
Wall mountable
Multi-directional flue (factory fitted on external models)
Removable control box

Grant Pellet Boilers

  

Unique and efficient

The new highly efficient Grant Spira Condensing Wood Pellet Boilers utilises Grant’s award winning patented stainless steel turbulator baffle
system, which is featured in Vortex Condensing oil-fired boilers.The units are available in outputs of 6-26kW with an efficiency of
97.4% gross,and 9-36kW with an efficiency of 93.1% gross. They come complete with a 110kg pellet store/hopper, which automatically supplies the Spira with. fuel


How the Spira works

An auger feeds the wood pellets from the hopper into a burner brazier/head where it is lit by an ignition element. The operation of the boiler is fully automatic.The intelligent microprocessors within the boiler also control the feed auger, the flue fan, boiler temperature and cleaning system.The fan in the burner propels hot gas generated from the fuel into the Spira’s primary heat exchanger. The heat energy is then transferred to water from the central heating system which is containedwithin, before being circulated around the house through radiators /under floor system. It is important to note that in other modern pellet boilers, up to 20% of the energy that is produced is lost to the atmosphere through waste gases exhausted by the flue system. The Spira has a unique secondary condensing heat exchanger which has been designed to capture most of this lost latent heat energy, so it can maintain extremely high efficiencies.The boiler’s cleaning system will periodically wash the condensing unit of any debris in the tubes and also activate the brazier within the burner to clear the combustion head of ash build up, which reduces maintance time.
