Biomass Boilers Farm

Biomass Boiler Added to Impressive Showroom Display

GES Mechanical UK Ltd has taken delivery of a Grant Spira biomass boiler which is now on display at their showroom which is based on Jupiter Business Park, Bentley.

The MCS approved Grant Spira Condensing Wood Pellet Boilers utilise Grant’s award winning patented stainless steel turbulator baffle system.

Single units are available in outputs of 6-26kW (on display at showroom) with an efficiency of 97.4%, and 9-36kW with an efficiency of 93.1%. They come complete with a pellet store/hopper and feed auger, which automatically supplies the Spira with fuel.

The process of burning wood produces ash, so wood pellet boilers (biomass) normally require a certain amount of regular cleaning and maintenance, which can be tedious. Grant has, however, found a better solution with their unique ‘self cleaning’ boiler design, reducing the need for cleaning to once a year under normal running conditions.

Key features of the Spira boiler:

* Up to 97% efficient

* Award winning condensing heat exchanger

* Automatic pellet feed and ignition

* Integrated pellet store

* Rapid ignition system

* Modulating Burner

* 125mm conventional flue

* Flue box with integral fan/draught stabiliser

* Automatic wash system for condensing unit

* Under normal running conditions requires servicing once per year

Marcus Payne, managing director of GES Mechanical, said: “The Grant Spira model is a quality piece of kit and is an ideal heating solution for domestic or commercial customers who are off grid.

“Commercial biomass installations already receive a generous payment scheme through the Renewable Heat Incentive (RHI) at 7.9p per kWh (for installations less than 200 kWth) and a similar payment scheme will soon become available for domestic users.

“The payback period for biomass installations is certainly impressive and, thanks to the RHI, will have paid for itself in three to four years based on average consumption*.”

*Example: a biomass boiler rated at 36kWth operates for 7 hours per day in winter and 3 hours per day in summer, i.e. 1,825 hours in total over the year.

This size of boiler is classified as ‘small biomass’. It therefore receives the tier 1 tariff of 7.9p per kWh for the first 1,314 hours and the tier 2 tariff of 2.0p per kWh for the other 511 hours.

* 1314 x 36 x £0.079 = £3737.16

* 511 x 36 x £0.020 = £367.92

Making a total of £4105.08 per annum (plus inflation adjustment)
