Grant Spira
The Grant Spira is a condensing wood pellet boiler that is easy to install, with low maintenance and straightforward to operate. The Spira will give some of the highest efficiencies and environmentally friendly results from biomass boilers. The Grant Spira has a rapid ignition system and generally does not require a buffer tank, and when combined with our modulating and self-cleaning burner, the system can operate with similar characteristics to an oil or gas boiler. For the homeowner, the patented boiler and burner self-cleaning system, along with automatic fuel delivery, results in minimal intervention once installed. Wood pellets produced to EN Plus standards have one of the highest calorific values in biomass. With low moisture content and, when paired with unique boiler and burner combinations, they deliver excellent combustion and efficiency.

The Spira was one of the first condensing biomass boilers on the market following many years of research and development. The different models available of the Spira boiler are designed to match in a convenient and safe way any home in a cost effective manner. The boiler is commonly installed in a garage / out-house or plantroom, or in a unique Spirapod which is an outdoor housing unit specifically for the Spira. Your installer will advise on the best location for your Spira, especially if you intend to use a bulk pellet store.
Spira boilers are available in outputs of 5-18kW, 6-26kW and 9-36kW. All boilers are supplied with a side hopper which must be specified as a left or right hand unit on ordering. Also included is the pellet feed auger which supplies pellets when needed to the burner. If required for larger applications, two boilers with separate flues can be utilised, with a central twin auger hopper option up to 72kW.
This is a very cost effective method giving larger outputs with excellent efficiency. In this scenario, both burners can modulate as one and reduce to a quarter of the maximum output when not required. With the incredibly high efficiency, low flue gas temperature and easy maintenance, the Spira is a unique option when installing a wood pellet boiler.
