Heating & Environmental Technology
Air Source Heat Pump
How it works
Even cold air is full of energy and air source
heat pumps use the freely available heat in
the ambient air to provide efficient heating
and hot water at air temperatures as low
as -25 °C. Because the source of heat – the
air – is abundantly available all around us,
air source heat pumps have the advantage
of low installation costs and minimal space
requirements, making them ideal for new
build applications.
Suitable for either indoor or outdoor
installation, air source heat pumps can be
used for heating, cooling and to produce
domestic hot water and with the relatively
mild winter temperatures in the UK, can
achieve seasonal co-efficient of performance
comparable with ground source, meaning
excellent levels of performance can be
achieved throughout the year.
Ground Source Heat Pump
How it works
The earth stores an enormous amount of
solar energy from both solar radiation and
rainfall, ground source heat pumps extract this
freely available energy to provide low cost,
low carbon, high efficiency heating and hot
water. To extract the energy ground source
heat pumps use collectors, filled with a mix
of water and antifreeze, buried in the earth,
either horizontally or, if available land area is
limited, vertically. Although more costly to
install than an air source heat pump, with the
constant temperatures below the surface of
the earth throughout the year, ground source
heat pumps deliver high levels of efficiency all
year round irrespective of seasonal variations
in air temperature.
Gas/Oil Condensing
Heating System
How it works
Modern condensing boilers simultaneously
generate warmth for heating and for hot-water
provision through the combustion of gas or oil.
By using the heat that remains in exhaust gas,
the energy content of the fuel is used almost
in its entirety, making gas-fired condensing
technology especially efficient as well as very
convenient.
These boilers can be wall or floor mounted
and an appropriately sized model will
be installed depending on the heating
requirement of the individual property.
Heat Recovery Unit
How it works
With air tighter new buildings, whole house
heat recovery ventilation is the most effective
ventilation strategy on the market.
Heat recovery continuously extracts humid
air from wet areas such as kitchens and
bathrooms and using a heat exchanger,
transfers the heat to filtered incoming outside
air which is redistributed to the living areas
and bedrooms.
Heat exchangers are up to 93% efficient
which significantly help reduce heating
bills, plus the effects of condensation are
dramatically reduced.
