Rising heating costs?
Find the rural solution to a rural problem
Farmers and rural estate owners are turning to biomass
heating as a way of cutting fuel costs, bringing properties
to optimum warmth, gaining income through RHI
and where possible, providing their own fuel.
70%
Cost savings against fossil fuels
Cost and Carbon Savings:
Renewable heat on demand
from HWEnergy.
Switching to biomass means:
We’ve been helping clients get the maximum from biomass
heating for over 11 years – from simple installs to more
complex district heating systems linking buildings together.
• Reduced CO2 emissions
Could you even do this using your
own home grown wood?
Biomass heating systems are backed
by over 50 years of development across
Europe. Modern systems are extremely
user friendly and deliver operating
efficiencies of over 90%.
Heating and hot water account for over 80% of the total
energy demand for a typical building.
Biomass heating operates in a similar way to oil or gas fuelled
systems but uses wood chip or pellet fuel sourced from
sustainable forestry plantations. Installing a wood fuel heating
system delivers one of the most effective ways to drive down
energy costs and reduce a building’s carbon footprint.
• Up to 70% reduction in heating costs
• An excellent rate of return on investment
• The opportunity to replace fluctuating
fossil fuel costs with locally sourced,
stable and sustainable fuel
Benefit from the
RHI with HWEnergy
Tariff Name
The UK government launched the Renewable Heat
Incentive (RHI) to encourage take up of biomass, and
other forms of renewable heating. The RHI provides an
incentive payment on every kWh of heat your biomass
heating system generates, ensuring a very attractive
return on your investment.

The benefits in numbers…
The natural fuel source available on your doorstep
Biomass heating provides farms and estate businesses with low
cost, green heating, using a home grown fuel source. The RHI
(Renewable Heat Incentive) has further enhanced this as an investment
opportunity. Typical returns on investment are between 12 and 25%

Project Planning:
Fuel sourcing and production
Producing biomass fuel on farms and estates is a simple and low
input process. Existing infrastructure such as sheds and tractors
can be used for storage and handling.
If you have your own forestry, you have the opportunity to
convert low value timber into a highly valuable heating fuel.
Once seasoned, you can hire a contract chipper to chip this
directly into the bulk fuel store.
Harvested round wood should be seasoned for 12 to 18 months
to achieve a suitable moisture content (around 15 to 35%).
If you don’t own forestry, you can buy in round wood or ready
processed wood chip fuel, both of which will be available locally.
Fuel Storage and Handling
A ‘bulk’ fuel store is required to hold perhaps 3 to 6 months
or even a year’s supply of processed wood chip fuel.
The best means of onward handling and delivering this to the
boiler fuel store will be determined by the equipment available,
distance to the bulk fuel store and other site specific factors.
HWEnergy will help develop the best solution with you on a
case by case basis.
Project Planning:
Fuel handling
Tipping into trough blower.
Tipping into underground fuel store.
Delivery by front end loader.
Tipping into fuel store using a ramp.
‘Rules of thumb’
for wood fuel
1 tonne of wood chip fuel
= 300 litres of heating oil
1 tonne of wood pellet fuel
= 450 litres of heating oil
1 tonne of wood chip fuel
= 5m3 of loose wood chip
1 tonne of wood pellet fuel
= 1.7 m3 of pellets
1 lorry load of seasoned round wood
= 20 tonnes
Average round wood seasoning
time for wood chip fuel production
= 12 to 18 months
Tipping into fuel store using high
lift trailer.

District Heating
Your own heating network
For biomass heat projects on Farms and Estates, it is common
to link several buildings together in a district heating scheme.
Houses, offices, swimming pools, poultry
sheds, grain drying systems, they can all be
linked via pre-insulated pipe-work lain
underground.
This enables multiple users linked to a centralised heating
system. End users can be metered individually, and separately
charged for heat usage.
HWEnergy Biomass Heat Cabins:
Packaged boiler room and fuel store solutions
Our biomass heat cabins come fully equipped
and ready for site installation with a pre-fabricated
boiler room and integral fuel store.
The units are available in a range of outputs, sizes and finishes,
and provide a convenient way of installing biomass heating.
