The Spira range is available in a variety of outputs and provides hot water via an open vented thermal store cylinder. By utilising the same patented Vortex condensing technology as Grant’s oil-fired boilers, the range can maintain efficiencies of up to 97%. Its unique, self-cleaning design collects ash from the combustion grate and heat exchanger tubes, reducing cleaning and maintenance to once a year, under normal running conditions.
MCS approved, the boiler was recently awarded Best Renewable Energy Product 2011 by the Sustainable Energy Authority of Ireland (SEAI).
