READ THIS BEFORE
INSTALLING
THE UNIT.
The installation of all un-vented water heating systems above 15
litres (this includes the ESP Hot Water ASHP’s) MUST
comply with local area Building Regulations. It is a legal
requirement that the local Building Control Officer be notified
of any proposed installation.
UK regulations require an appropriately sized expansion vessel
(internal or external) to be incorporated, safety devices to prevent
the stored water exceeding 100°C, and pipe work to convey
discharged hot water safely away from the safety devices.
Furthermore, the installation must be carried out in
accordance with this manual and by an engineer who has
successfully completed a recognised course in the
installation of un-vented heating systems such as CITB. The
guidance contained in the Good Practice Guide should be
followed. Failure to fit the unit correctly and in accordance
with regulations may affect its safety, efficiency and WILL
invalidate any guarantee.
THE UNIT MUST BE INSTALLED, COMMISSIONED AND
MAINTAINED BY A COMPETENT INSTALLER IN ACCORDANCE
WITH BUILDING REGULATION G3 (ENGLAND AND WALES),
TECHNICAL STANDARD P3 (SCOTLAND) OR BUILDING
REGULATION P5 (NORTHERN IRELAND) AND THE WATER FITTING
REGULATIONS (ENGLAND AND WALES) OR WATER BYELAWS
(SCOTLAND). FOLLOWING INSTALLATION AND COMMISSIONING,
THE OPERATION OF THE UNIT SHOULD BE EXPLAINED TO THE

2.0 System Overview
2.1 General Information
Air source heat pumps are similar in operation to ground source heat pumps,
except that heat is extracted from the air rather than the ground. Air source
heat pumps are classified as either air to air or air to water depending on
whether the heat distribution system in the building uses air or water.
The main advantage of air source heat pumps over ground source heat
pumps is their lower installation cost. A ground source heat pump requires a
network of underground coils that is used to extract heat from the ground. By
comparison, air source heat pumps extract the heat directly from outside air
and so avoid these potential problems.
5 of 52| Earth Save Products-ASHP PASRW030B-D-PS
V 1.8 PASRW040B-D-PS
PASRW050B-D-PS
Benefits of air source heat pumps over conventional boilers include the fact
there is no combustion and no explosive gases within the building, no need
for flues or ventilation, no local pollution, long life expectancy with minimal /
no annual maintenance, simple engineering/fitting and lower running costs.
Depending on the comparison fuel and heating system being compared to
the ASHP, savings can be up to 75% and the units are designed to have a life
span of 20 years with no substantial annual required or recommended
maintenance.
Component parts of ESP ASHP units are from industry leading manufacturers
such as the Danfoss heat exchanger, Wilo water pump, Copeland compressor
and Carel controller, so reliability and longevity is ensured.
