How the air to water heat pump market is going to be big business in the UK and problems that may hamper it (2011)
to water heat pumps for houses will be big business for plumbers and air
conditioning engineers within the next decade. Many air conditioning
engineers are now gaining the correct training to get the accreditation
for entering a manufacturers installers program. The main players within
the air to water heat pump market are Daikin with the Altherma and Mitsubishi Electric's
Ecodan. Both units require the manufactures accreditation to
install their equipment.
of blending of skills:
issue with the air to water heat pump market in the UK is that plumbers
are installing equipment without a full understanding of heat pump
technology and air conditioning engineers do not have the plumbing or
heating engineer skills required to do a full heating system
installation. This lack of blending of skills give plumbers a better
chance of getting the installations as they have most of the skills
involved to do the main installation such as fitting radiators and
general plumbing services. The but is plumbers slip up with a lack
of basic knowledge of a refrigeration cycle. A good example of this will
be when a refrigeration component fails and a heating engineer will not
have the skills to change it.
pumps have a COP cost-efficiency of performance which
basically means that electrical power going in is multiplied to
produce more heat output. i.e if a heat pump has a COP of 4.2 it will
produce 4.2kW of heat for 1kW of electrical input power. The COP figure
is relative to outside ambient temperature so most heat pump
air to water systems output is highly seasonal. In the middle of winter
when temperatures in the UK can go sub -20DegC this COP figure will hit
sub 1.5 COP. So your 15Kw air to water heat pump boiler in the middle of
winter will only produce 7kW of heat.
air to water is different to ground source heat pumps:
all my time in the air to water heat pump sales market I have seen
drawing with heat allowances of 65watts / meter for houses under floor
heating. This seems to be a common theme when plumbers quote on a air to
water heat pump system. As in the above subject in the winter air to
water output figures can be as low as 50% rated output when the cold
season temperature is taken in to account. This is not an issue for
ground source heat pumps because the ground at which the pipes
are berried is at a constant temperature of around 10 DegC.
Things to remember:
with a minimum of 100Watts / meter
into account the seasonal temperature outputs
and blend skills within your company
to water rated output is not linear
to water and ground source are completely different and
sizing calculations will be different and not comparable
in 2013 will by law have to have a seasonal rating (SEER)
