1 USER INSTRUCTIONS
1.1 Intended Use
The Warmflow Air Source Heat Pump units are intended for the production of hot water for space
heating and sanitary water. The units can be used to provide heating and domestic hot water
(DHW) via underfloor heating circuits, radiators and approved hot water cylinders. The units are
designed to extract heat from the air.
1.2 Compliances
The Warmflow AS01-R32, AS02-R32 and AS03-R32 air source heat pump units are
Microgeneration Certification Scheme (MCS) approved and hold both UKCA and CE markings.
They are approved on the Renewable Heat Incentive Eligibility list and can be found on both the
Product Characteristics Database (PCDB) as well as the Home-heating Appliance Register of
Performance (HARP) database. As such the units comply with the following directives and are
tested to the following standards:
MCS 007 Issue 3.0 - Product Certification Scheme Requirements: Heat Pumps.
2006/95/EC - Low Voltage Directive.
2004/108/EC - Electromagnetic Compatibility Directive.
97/23/EC - Pressure Equipment Directive.
EN14511 - Air conditioners, liquid chilling packages and heat pumps with electrically
driven compressors for space heating and cooling.
EN14825 - Air conditioners, liquid chilling packages and heat pumps, with electrically
driven compressors, for space heating and cooling. Testing and rating at part load
conditions and calculation of seasonal performance.
EN 60335-1 - Household and similar electrical appliances. Safety. General requirements.
EN 60335-2-40 - Household and similar electrical appliances. Safety. Particular
requirements for electrical heat pumps, air-conditioners and dehumidifiers.
EN 61000 - Electromagnetic compatibility (EMC). Limits.
EN 378 - Refrigerating systems and heat pumps. Safety and environmental
requirements.
ENV 12102 - Air conditioners, liquid chilling packages, heat pumps and dehumidifiers
with electrically driven compressors for space heating and cooling. Measurement of
airborne noise. Determination of the sound power level.
1.3 Basic Operation
Heat flows from an area of higher temperature to an area of lower temperature. In much the
same way that a water pump, pumps water from a low level to a higher level, a heat pump pumps
heat from a source at a low temperature to a source at a higher temperature. The benefit of this
is that natural sources such as the air and ground, which are at relatively low temperatures, can
be used to heat buildings at a higher temperature. In order to do this the heat pump uses a
relatively small amount of electrical energy. The proportion of electrical energy used to do this is
much smaller than the heat power delivered to the building. The ratio of the heat power delivered
to the electrical energy used determines the efficiency of the heat pump and is commonly known
as the coefficient of performance (COP).
