Spira condensing wood pellet boiler

The Grant Spira condensing wood pellet boiler combines easy installation with straightforward operation and low maintenance.

The Spira is suitable for homes of all sizes and is a safe, cost effective and convenient way to heat any rural home. The Spira range was the first condensing biomass boiler in the UK to be eligible for the Renewable Heat Incentive Scheme and was awarded Best Renewable Energy Product 2011 by the SEAI. The Spira utilises our exclusive turbulator baffle system, providing highly efficient, environmentally friendly heating.

Features & benefits

  • Pellet vacuum systems also available/ Can also be fed from a bulk pellet store
  • It has a rapid ignition system with modulating burner so can operate in much the same manner as a standard oil or gas appliance giving a greater degree of control over your energy usage.
  • Grant biomass boilers have unique built in self-cleaning heat exchangers, along with an automated fuel feed so intervention is kept to a minimum.
  • Grant biomass boilers use one of the most efficient forms of off gas fuel – wooden pellets. Compared with logs and wood chips these have a very low moisture content, which helps with combustion efficiency and therefore reduces energy consumption.
  • The Grant Spira range can be housed in either a garage or out-house, or you can utilise one of our unique SpiraPod outdoor boiler housings
  • The boilers come complete with an adjacent pellet hopper and feed auger, which automatically supplies the Spira with fuel.
  • There is also the option of increasing the output by utilising two boilers (separately flued) and a central hopper/twin auger arrangement. Using two boilers to achieve higher outputs is very cost effective. When the units are combined their precise electronic burner controls allow both units to modulate as one, down to just 25% of maximum load when the full output is not required.
  • DEFRA approved under the Clean Air Act
  • Flue box with integral fan/draught stabiliser
What is a biomass boiler?

What is a biomass boiler?

Biomass boilers are fully automatic appliances, behaving more like an oil or gas boiler, and use advanced controls which cleverly regulate the amount of fuel being delivered to the burner to match the heat demand on the boiler. The fuel is fed to the burner via an auger connected to the adjacent pellet store/hopper. This can, in turn, be automatically supplied from a bulk pellet store which can vary in size.

Unlike fossil fuels which are a depleting resource, biomass fuel can be sourced from a “closed carbon cycle” system, where the amount of carbon emitted during the burning of fuel is balanced by the planting of trees.  This environmentally friendly way of harvesting fuel to heat your home, therefore cancels out the harmful effects of  carbon being released into our atmosphere.  Trees need carbon dioxide to grow so it is good partnership, one which is environmentally friendly.

The term biomass refers to a type of fuel sourced from living/non living plant matter, which could be in the form of either wooden logs, wood pellets or chips – wood pellets being the most energy efficient.  Our condensing biomass boilers use wood pellets.
