Renewables
The following gives an overview of the main renewable
technologies. For more detailed information contact your local
branch or download

Air to Air
With high efficiency levels these pumps offer heating in the
winter with the additional benefit or air conditioning in the
summer.
Air to Water
Works well with underfloor heating and radiators and using the
right accessories can be docked with other technologies such as
solar panels.
Exhaust Air
Extracts warm air, via ventilation ducts, from other areas of
the house (bathrooms / utility rooms) and extracts and reuses this
heat before expelling the cold air.
Ground Source
Using shallow or deep drilled collectors heat is transferred
from the ground to a heat pump via a mixture of water and and
enviromentally friendly anti-freeze.
Heat Recovery
Often referred to as MVHR this technology simultaneously
extracts air from wet rooms (kitchens and bathrooms)
and supplies fresh, filtered air to habitable rooms.
Heat Pump Cylinders
Differ from traditional cylinders as they feature a specially
designed coil, usually with a larger surface area, which maximises
heat transfer.
Solar Photo Voltaic (PV)
These are in fact are modules placed on the roof of a building
which contain cells that generate an electrical charge when
exposed to direct light.
Solar Thermal
These panels contain vacuum tubes to collect solar radiation and
are considered to be the premium product on the market due to
their increased efficiency.
Flat Plate Panels
The most common product on the market, thanks to their cost
effectiveness in both commercial and domestic use. These dark
panels absorb solar energy and transfer it to a heat transport
fluid to extract the energy.
Solar Thermal Cylinders
These cylinders ordinarily contain an electric immersion heater
to meet the additional hot water demand at times when solar energy
may not be sufficient.
Rain Water Harvesting
Collected from roof tops and stored in an undeground tank water
is then pumped back into the building and can be used to flush
toilets; wash laundry; water gardens or wash vehicles.
Grey Water Recycling
By capturing waste water from baths and showers and reusing for
things like flushing toilets, this can reduce fresh water usage by
upto 30%
Water Flow Solutions
Simple technologies like, tap flow restrictors, dual flush
toilets or lower capacity baths can all add up to reduce water
useage per head per household whilst being simple to install.
