2 TECHNICAL AND DIMENSIONAL SPECIF ICATIONS
2.1
Operating principle
The all in one air to water heat pump uses the energy of the air existing in the environment. The
air required fo r the proper operation of the heat pump can be drawn from the out s id e through
a window (mi n i mum temperature -20°C) / from the s urroun din g environment or from other
environments through ducts. The air drawn from the environment is sucked through a fan and
the heat existing in the air is absorbed during the passage in a heat exchanger (evaporator). In
the evaporator the heat taken from the air is caused to evaporate at low pressure by the
refrigerant (the working fluid in the refrigerant circuit, as in a household fridge). The vaporized
refrigerant is drawn through a compressor and raised to a higher level o f pressure and
temperature. In a second heat exchanger (condenser) the higher temperature hea t is absorbed
and transferred to the water; this way the vaporized refrigerant f l u id condenses back to the liquid
state as a consequence of thermal dissipation. The liquid refrigerant, f l owi ng through a choking
component (expansion valve), undergoes a low-pressure expansion (dilatation) and, after
returning to the evaporator, it can again draw heat from the surrounding environment.
The hot water heat pump operates at ambient temperatures ranging between -20°C and
+ 4 3° C.
The hot water heat pump is a connection-ready equipment whose function is heating drinkable
water; it basically consists of the water tank and of the refrigerant, air and water circuit
components, as well as of all the c o ntrol , adj u s t ment and monitoring devices required for
automatic operation.
> Use o f th e environment e n e r gy
Refrigerators, washing machines, heating systems and other equipment/electric appliances
generate heat that in most cases is not re use d . Ins t ead of being dispersed into the environment,
generating pollution, the hot air in question can suitably be used to heat sanitary water: a
sensible and environment-friendly solution.
An important benefit is the air dehumidification resulting from heat suction, decreasing the
degree of humidity in cellars and laundries.
This has two beneficial e ffec t s: environment protection and production of cheap hot sanitary
water.
2.2
Energy ef ficiency

EcoStore - He a t pump water heater
EN
10 | P a g e
> Free ener gy
The necessary energy for the heating of sanitary water comes for 2/3 from the air and 1/3 from the
electric power s u pp l y .
> Coo ling through the heat pump f o r hot sanitary water
After heat s u b t r a c t ion, the lower-temperature output air can be used during summer to cool t h e
environment where the heat pump is installed.
This provides a double benefit, while ensuring optimum energy eff i ciency .
> Industr i al use of energy
The heat pump for hot sanitary water can be beneficially installed in stores and workshops
(hairdressers, bakers, butchers, kitchens, factories), to gethot sanitary water and, if n ee d ed , cooled a i r .
2.3
Hotwater temperature
Setting watertemperature target range: 38÷ 65° C.
Using renewable energiesand ensuring optimum energy e ff i ci e n cy , the heat pump for sanitary water
provides an environment-friendly and cheap solutionto heat water all over theyear.

Hydraulic connectio ns
The
assembly of the safety valves must be done in conformity to the G3 regu lation s in force.
We recommend the integration of a filter in the cold-water supply pipes.
We recommend that you in s t al l the equipment close to the main hot water draw off point, to
prevent heat dispersions along pipe work, and if possible, near a drain, for easier emptying and
condensate discharge.

Hydraulic safety unit
(manda tory)
You must install all safety components s u pp li ed in the G3 kit to comply with Building
regulation G3 or with equivalent s t an dar d s in force including:
- Multiblock Pressure reducing / check / safety valve
- Temperature & Pressure relief valve to cylinder
- Expansion vessel
- Tundish
The above components are required to safely run the s u pp lied equipment. The rated calibration
pressure of the temperature and pressure relief valve must be of 0.6 MPa (6 bar). Pay attention
while installing the s a f e t y components , avoiding forcing or alteration . You need to install a
discharge pipe, with a constant downward slo p e , in a con d ens a t e - and ice-free area. There must
be no obstructions in the pipe, to avoid ov er p r essu re s.

3.1.2 Pressure redu ce r
Should the network
pressure exceed 0.6 MPa (6 bar), you need to install an appropriate
pressure reducer upstream of the hydraulic safety un it , ensuring the indicated operating ran g e.
3.1.3
Expansion tank
To prevent any
overpressures that might damage the equipment, frequently triggering the safety
unit and causing water drippin g , it is mandatory that you install an adequate expansion vess el.
Install it in accordance with the instructions provided by the ma nu f a c t u r er . The expansion tank is
required to keep pressure constant and avoid harmful pressure shocks or accidental ove r p r e s su r e s.
3.2
Unit filling
WARNING: Switching on the equipment when it is not filled with water will seriously damage
the refrigerating units an d the electrical heating element.
WARNING: In the presence of water with a hardness degree >20°TH (where 1 ° T H = F r e n c h
degree=10mg CaCo3/l) it is mandatory that you install a softener to reduce limestone
scaling inside the boiler and keep the electrical resistance and the hydraulic safety unit
in good worki ng order.
To fill the equipment, you need t o :
•
open the main water supply valve.
• open a hot water tap (e.g. b a throom , wash basin, etc.) to allow the water to flow out; when
the water outflow from the tap is constant the equipment will be fu ll ;
C heck that there are no leaks from the hot / cold water system.
We recommend that you flush the pi pes before connecting the unit .
Only proceed with the electrical connection after performing this operation
