Award winning high efficiency condensing biomass boilers, perfect for rural home heating
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.
Just some of the many benefits of installing a Grant biomass boiler:
A rapid ignition system with modulating burner
Our boiler can operate in much the same manner as a standard oil or gas appliance giving a greater degree of control over your energy usage.
Requires little intervention
Grant biomass boilers have unique built in self-cleaning heat exchangers, along with an automated fuel feed so intervention is kept to a minimum.
Lower energy consumption and greater efficiency than the competition
Thanks to our award winning patented condensing heat exchanger, Grant are able to provide some of the most efficient boilers on the market in the UK.
Uses wood pellets for efficiency
During the burning of any fuel any water content must be evaporated prior to combustion, this requires additional energy. 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.
Suitable for homes of all sizes
Biomass boilers are a safe, cost effective and convenient way to heat any rural home, but one thing to consider is the amount of space required. For example, 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. Knowing exactly where you will be locating the unit at your property is an important consideration before purchasing, especially if you are planning to utilise a bulk pellet store.
Grant wood pellet boilers are guaranteed for one year from the date of installation, unless the installation is more than six months from the date of purchase in which case the guarantee period will commence six months from the date of purchase. The guarantee period will be extended to a total of two years (excluding consumable items) if the product is registered within 30 days from installation , subject to being serviced annually and installed in accordance with the manufacturer’s instructions. The heat exchanger (jacket) within Grant’s biomass boilers is covered by a five year guarantee. On completion of the installation, all Grant wood pellet boilers must be commissioned and registered online.
Biomass Suppliers List
The Biomass Suppliers List (BSL) is a list of suppliers of wood fuel who have been accredited as demonstrating that their fuel meets the sustainability criteria required under the Renewable Heat Incentive. Recipients of the Domestic RHI and Non-Domestic RHI are obliged to source their fuel from suppliers on the BSL. For further information regarding the BSL, please click on the following links:
