Renewable Heating
RENEWABLES AND ENERGY SOLUTIONS
Air Source
Heat Pumps
Air source heat pumps work by absorbing heat
from the outside air at low temperature into a
fluid (a liquid refrigerant), then passing it through
a compressor to increase its temperature. The fluid
is then transferred to the heating and hot water
circuits of the house. The principle works even in the
middle of winter at temperatures as low as -15ºC.
Heat pumps work much more efficiently at lower
temperatures than a standard boiler system
meaning they are more suitable for under-floor
heating systems and use with larger or fan
assisted radiators, which give out heat at lower
temperatures over longer periods of time.
How Air Source Heat Pumps work
1. Energy from the outside air
is transferred to the liquid
refrigerant and circulated
through the evaporator.
2. The heated refrigerant gas is
then compressed to reduce
its volume but increases its
temperature.
“We offer the High Performance, T-Cap and HT range from innovative brand leaders Panasonic
both in monobloc (requiring no refrigerated connection) or split/bi-bloc (with separate indoor and
outdoor unit). Let us help you specify the right system for your environment”
3. The compressed gas enters the
condenser surrounded by water
from the heating system, where
it gives up its heat.
4. The cooler liquid refrigerant
then passes through the
expansion valve which reduces
the pressure.
Biomass
Boilers
What is Biomass?
Biomass is waste material - mostly from wood
- that is used to create heat, liquid biofuels, and
electricity. Wood is one of the most natural
and sustainable fuel sources available to us, it
has a carbon neutral cycle as it releases about
the same amount of carbon dioxide into the
atmosphere through burning, as it absorbs
during growth process. Wood pellets are
produced by compression of sawdust or wood
shreds to create a pellet that has typically below
10% moisture content meaning pellets have
a high volume energy density. They are also
clean, consistent and flow easily, making them
particularly attractive in domestic applications.
Biomass fuel offers an economic incentive to
manage woodland and improve biodiversity.
The fuel has clean burn credentials and
super efficiencies as well as the capability to
significantly reduce carbon emissions. Although
the price of wood fuel varies considerably, it is
often cheaper than other heating options.
Why Biomass?
Controlled in a very similar way to an oil or gas
boiler, biomass wood pellet boilers can offer
super efficiencies in excess of 90% meaning a
more viable option for properties particularly in
rural areas that currently have an oil or non-gas
heating system installed.
Advantages of a Biomass Boiler system?
■ Biomass boilers are said to be close to
carbon-neutral
■ A new boiler can be easily connected to your
existing heating system with very little or no
disruption to your premises
■ Biomass boilers are very efficient, durable,
clean and easy to use, requiring minimal
management time
“We have a comprehensive range of both domestic and commercial biomass pellet boilers , designed
and manufacturered to the highest standards to offer credible and cost effective alternatives to heating
properties. Choose from internal and external models ranging from 15kw to 28kw for domestic use and up
to 250kw for commercial use , including cabins which can be built to your specification”.
