2. Overview of ASHP system supplied
Heating & Hot Water preparation in detail
Radiators (Panel Heaters)
To optimise the maximum effi ciency and lowest fl ow rate from the heat pump to heat the room, radiators can be wider or deeper than
radiators you expect to see when connected to a boiler system.
For maximum effi ciency and individual room temperature control, Thermostatic Radiator Valves (TRV's) are fi tted.
Most radiator thermostats will either have numbers or roman numerals marked on them when they are adjusted, the higher the
number, the warmer the room target set will be.
Underfloor Heating (UFH)
Where underfl oor heating is installed you will see a manifold in a cupboard with pipes coming off them and going into the fl oor, these
pipes heat the fl oor and therefore the room, the room temperature will be controlled by a room thermostat connected.
Do not use a high insulated product in fl oor fi nishing as this will inhibit the heat being transferred from fl oor to air, and in turn
increase the fl ow temperature to achieve target air temperature, with increased running costs.
Fan Coil (fan Assisted Radiators)
Designed to operate at a lower fl ow temperatures than traditional radiators to heat the room and ideal to be used with heat pumps
where underfl oor is not an option.
The Panasonic Aquarea system main components
Outdoor Unit
The outdoor unit extracts temperature from the air when the fan is turning to start the process of changing this low temperature to a
high temperature using a compression cycle, once the compression cycle is carried out the heat is transferred to the heating or hot
water depending on requirements.
Monobloc
Panasonic supply 2 types of heat pumps, fi rstly a Monobloc system, in this system the hot water produced to feed the heating
and hot water is produced externally from the property inside the outdoor unit.
Bi-Bloc
The other Panasonic unit is called a Bi-Bloc system this unit generates hot water from an internal unit (Hydro module)
connected to an outdoor unit.
All in one*
New All in One hydromodule + 200l tank
Panasonic has developed a highly effi cient solution, easy to install.
Based on the Bi-Bloc system, you have an outdoor unit, with the Hydro Module and DHW Cylinder all in one cabinet indoors.
*Preliminary design. Signifi cant changes may occur.
Cylinder
Where a system is installed to supply hot water their will be a cylinder with ready to use stored hot water at approximately 50°C, this
water is lower than you would expect from a boiler system but hotter than you require for washing/showering 39-44°C, more volume is
stored to compensate for less cold water mixing for use, therefore saving money on not heating water to a higher stored temperature.
Room Thermostat
This allows a simple adjustment to the room temperature, the higher the room target set the higher the running cost. It can be
supplied as an option by Panasonic (PAW-A2W-RTWIRED or PAW-A2W-RTWIRELESS) or another one can be used.
