Kernow Fires Kernow Biomass

Kernow Biomass has a Biomass showroom in Wadebridge. Graham, our Biomass expert is experienced in heating and plumbing installations, and is able to guide you through the information process all the way to installation and maintenance of your new heating system.

Some of the reasons people are converting to Biomass in Cornwall:

Wood pellet, chip and logs are still cheaper forms of heating than oil, electric and LPG.

The current government RHI grant scheme offers 7 year domestic and 20 year commercial tariffs, which will pay back initial costs and in most instances return a profit.

Pellet and chip offers near maintenance-free heating

Biomass is a sustainable source of heating which should remain competitively priced in the future despite the inevitable rising cost of oil and gas.

The Kernow Biomass Showroom based on Trenant Industrial Estate in Wadebridge has the KWB Pellet Fire Plus commercial pellet biomass boiler system working and providing heating and hot water for all our buildings. Alongside this is a selection of other green heating options including a domestic biomass pellet boiler from winhager and HDG, hot water solar panels and information on ground and air source heat pumps. The biomass boiler showroom connects to our stove showroom which displays over 80 wood and multifuel stoves including a number with boiler stoves.

Graham is on hand to answer any initial questions you may have regarding a biomass heating systems and RHI (Renewable Heat Incentive) grants. He can help you assess your requirements and suggest the appropriate green heating system prior to carrying out an initial assessment of costs and feasibility. We offer a complete package from the very beginning, including design, building works, installation and ongoing maintenance.

Introducing our Products. KWB stands for Kraft (power) and Wärme (heat) from Biomasse (biomass) and is synonymous with cutting-edge biomass boiler heating systems. The brand from Styria in Austria was created by the pioneering spirit of the researcher August Raggam and the committed organic farmer Erwin Stubenschrott, who as the pioneers of regenerative energies have always followed a clear vision: We Provide Energy for Life! Kernow Biomass are the installers for KWB biomass boilers in Cornwall.

With this promise, KWB provide our customers with the certainty that KWB's biomass heating systems set an unmistakable signal for the responsible handling of resources and the protection of life for the next generations on our Earth.

Euroheat modern log boilers provide clean and efficient heating: they are fuel led by hand once or twice each day. When sized correctly the fuel chamber is large enough to hold enough energy in the form of wood to supply the average winter daily heating requirements. Occasionally during severe weather a second load may be required.

They operate at high levels of efficiency and have large fuelling chambers. Log boiler systems are applicable to all domestic sized situations and for smaller commercial applications, such as country houses and small industrial buildings.

Log boilers begin to become less practical if the system design requires regular refuelling. A correctly sized log boiler in average winter conditions will be ignited and fuelled once per day. In colder periods a second operation maybe required. When choosing a log boiler the main decision is the fuelling chamber size when deciding on a particular unit, not the kW output of the boiler.

Ground Source Heat Pumps extract heat from the ground to provide efficient heating and hotwater. A popular choice for new builds and highly insulated homes. Efficient and low energy source of heating. Significant savings can be achieved under the Governments Renewable Heat Incentive Scheme (RHI). Fuel bills can be reduced as this system runs on very efficiently on electricity.

Air Source Heat Pumps extract the outside air, to provide efficient heating and hot water.

An air-to-water system has similar benefits to a ground source heat pump but with the advantage of requiring significantly less space to install.

  • biomass boilers cornwall biomass cornwall renewable heating cornwall

Key Features & Benefits of Ground and Air Source Heat Pumps:

Renewable Heat Incentive: significant savings can be achieved using air source heat pumps, under the government's new scheme the 'Renewable Heat Incentive' (RHI) allowing for an annual pay back rewarding those who invest in such qualifying technologies.
Reduce your fuel bills: air source heat pumps run on electricity, so there's no need to pay for other more expensive forms of heating using gas, oil or solid fuels.
Cut down on wasted electricity: heating your home with an air source heat pump is much more efficient than other conventional heating systems.

Photovoltaic Panels (PV) capture the suns energy converting the sunlight into electricity, which can be used to run household appliances and lighting.

Each cell is made from one or two layers of a semi-conducting material, usually silicon. When natural UV light shines on the cells it creates an electric field. The stronger the solar radiation, the more electricity is produced. Recently introduced government schemes provide financial incentives to promote the installation of solar PV allowing you to benefit from lower electricity bills as well as profit from a guaranteed regular income (tax free).

Once your system has been commissioned by our MCS approved installers you will be able to claim a fixed figure for every unit of electricity produced.

Our panels are very easy to maintain with no moving parts and a self cleansing glass. Solar PV installations can provide up to 50% (sometimes more) of your annual electrical requirement, depending on the size, orientation and pitch of the array. The strength of PV cells is measured in kilowatt peak (kWp) – that's the amount of energy the cells generate in natural daylight.

Key Features & Benefits:

Feed in Tariffs: receive a set payment for all the electricity you produce, even if you use it yourself. The scheme not only allows you to recover your initial installation costs, but allows you to profit from solar PV generation for many years to come.
Cut your electricity bills: By creating your own electric supply you're able to reduce the amount of electric purchased from your energy supplier.
Sell electricity back to the grid: if your system is producing more electricity than you require, your system will automatically export the excess electricity back into the grid – this will entitle you to a 'bonus' payment of 3p per unit depending on the size of your system.

Rainwater Harvesting involves collecting rain from your roof tops then sending it down the guttering pipes to an underground storage tank buried within your garden.

The rainwater will first be filtered, and then an efficient submersible pump (which sits within the storage tank) will deliver the water (via a floating suction filter) back to the toilets, washing machine and garden taps. This could save you over 50% of your total water usage.

The pressure hose and any cables are ducted to the house through a sleeved pipe, any excess water from inside the tanks will discharge through a trapped overflow.

All our rain harvesting systems are compliant with current water regulations.

Key features & benefits:

Saves mains water: saving on your water bills by up to 50% of mains use.
Wide range of applications: rainwater can be re-used for flushing toilets, washing machines and garden taps.
Ideal for remote locations: provides an alternative to mains supply of water in remote areas.
