User and installation manual
General information:
The heat pump usually covers a family's need for hot water throughout the year. BWP 270 1A is equipped with an
additional internal heat exchanger (coil, built into the hot water tank). This design opens the possibility for dual-fuel
installations (HP + boiler or solar station or electric) and to use the DHW HP as primary source for heating or heating
support (e.g. if the central heating boiler is switched off in the summer period, the DHW HP coil can be used to procure
heating energy or the partial heating of bathrooms and other small spaces. Refer to page 19 "Connection Example".
The installation and the first launch of the DHW HP have to be made by a qualified and authorised installer according to
the instructions and recommendations of this manual. Before connecting the DHW HP to the mains, the DHW HP and
the installation have to be filled completely with water and to be checked for leakages. Ensure that the air flow
requirements are met (room volume, air source, vent …). At first launch (or when the tank has been drained) the heat-up
time (ambient air temperature of approx. 15°C, DHW temperature 45-55°C) is likely to be 8 to 10 hours. Choose the HP
operating mode to start, perhaps in combination with the supplementary heating.
NOTE: The appliance is not to be used by children or persons with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge unless they have been given supervision or instruction. Children must be supervised
not to play with the appliance.
HP WORKING PRINCIPLE:
The HP is the prioritized energy source for the generation of DHW. The heat pump operates according to the air to water
principle: The energy is extracted from the ambient air in the evaporator. In order to ensure the energy supply, the air is
forced through the evaporator by a powerful fan. The energy is transported in the HP circuit from the evaporator to the
compressor- In the compressor the energy will be transformed to a higher temperature level. This process only need
30% of the thermal output energy as input (as electrical energy for fan and compressor, the thermal energy comes for
free from the air). Finally the thermal energy from the compressor is transferred via condenser (external heat exchanger)
to the DHW tank to generate DHW. Thus you are saving 70% of energy and energy cost.

INSTALLATION
CHOICE OF THE INSTALLATION LOCATION:
Wherever possible, the heat pump should be installed close to the existing hot-water conduit.
The location must be indoors in a frost-free environment with a frost protected sewer drain. The floor at the location
must be flat and at level. Minor irregularities can be levelled by means of the adjustable feet. It has to support the weight
of the DHW HP (approx. 430 kg filled). The location must be designed to support the corresponding load. If the HP will
operate mostly on off peak hours do not install the product near to bedrooms. Even if the DHW HP operates very silently,
this might disturb sensible users. Please ensure that the location and the DHW HP are easily accessible for maintenance
and service. All damages and service impossibilities (e.g. repair), due to the reduced accessibility are part of the
installer/user responsibility and not covered by the manufacturer’s warranty.
NOTE: State-of-the-art building regulations, standards and legal requirements must be observed.
Unused connectors (Coil, recycling loop) have to be sealed and insulated properly in order to avoid heat losses.
The DHW HP works either with ambient air or outside air. Independent of the installation mode there are some basic
requirements for the air quality of the airflow:
-The air must be dust and grease free
-The air source should benefit from free energy gains like in the laundry (dryer waste energy), kitchen,
garage (appliances and car waste energy), basement (geothermal energy) and heating cabinet.
-The air temperature must be > -10°C
-The air source can benefit from dehumidification
-The exhaust air is cooled down and can be used for cooling e.g. a wine cellar
The easiest way to install the DHW HP is the ambient air installation:
In the ambient air mode the product doesn’t need ducting. The air inlet uses the ambient air of the location and the air
outlet exhausts the air into the same room. This installation mode needs some requirements:
-Room volume > 20 m3
-Free air flow, no air re-circulation (air short-circuit between inlet and outlet
-Ventilation of the location (air inflow > 200 m3/h
-Location must not be heated by a heating system
In this installation mode the fan speed should be adjusted at “high”. Anyhow, if you should want to change the fan
speed for comfort reasons to “low”, you can do so without a considerable decrease of performance.
Semi ducting or full ducting can increase the efficiency. In this way you can optimise the airflow and the efficiency.
-Semi ducting is usually used for the exhaust side to avoid mixing ambient and exhausts air.
-Semi ducting helps to reduce the noise level
Full ducting on air inlet and air outlet gives the possibility to position air inlet and outlet independent of the DHW HP
location. Full ducting is also recommended for the use of exterior air.
In this installation mode the fan speed should be adjusted at “high”.
It is also possible to use the DHW HP ducted with extracted air. For this special application the minimum air flow
requirements of the HP have to be matched with the airflow design of the ventilation.
The fan speed for permanent operation can be selected separately.
For more details see “air connections – ducting”
PREPARATION FOR INSTALLATION:
The heat pump is delivered adjusted and ready assembled with wire and plug. Just connect the water inlet and outlet to
the piping. The defrost water from the evaporator is evacuated by a drain (13) and has to be connected to the sewer. The
dimensions of the DHW HP and the connections see “design & dimensions”.
General rules for hydraulic connection:
Your DHW HP has a high quality steel tank for the DHW generation. This tank inside is enamelled and gives you a perfect
protection against corrosion in combination with an additional catholic protection (magnesium anode). Nevertheless, in
order to protect the tank and also the connectors you have to avoid connecting copper pipes to steel or galvanized steel
fittings directly (in flow direction). The use of insulation fittings is mandatory in this case.
NOTE: The installation must be done according to the state of the art of installation. The non-respect of these rules and
abnormal water composition may be the reason of warranty exclusion. The manufacturer has no liability for the
installation and possible damages to it.
