Heat Pump System Theory:
(1) Using a small power input to drive the compressor, the power used is Q1.
(2) While the unit is running, the power that comes ambient air is Q2 (from the refrigerant
transformation).
(3) The energy that the water gets from the unit is Q3.
(4) According to the law of conservation of energy:
﹛
Sum of input power = sum of output power Q1+Q2 = Q3
﹛In standard working conditions, the power that heat pump gets from the environment is about
3.2 times the power input, Q2 = 3.2 x Q1
so: Q3 = Q1+Q2 = Q1+3.2Q1= 4.2Q1
Which means you can get 4.2Q1 from heat pump if you spend Q1 energy. Which means the
energy that you can get from heat pump after using 1 kW of electricity is equal to the energy that
you get from electrical element heater after using 4.2 kW of electricity. This makes the hot water
heat pump is one of the most energy efficient heating equipment available on the market today..

Indoor Installation Recommendations
Heat pumps operate most efficienctly with warmer air temperatures, and the outlet air from
the unit will be colder than the inlet air. Therefore it is advisable to install the unit so it
recieves the warmest air temperatures possible and the cold air is not able to recirculate
back into the unit.
The unit may be able to be installed in an unventilated room exceeding 25m3 in volume.
Venting of cold air is always advisable to prevent the air temperature dropping and lowering the
efficiency of the unit.
Think of the unit as a 3kW airconditioner for the effect it will have on a closed room.
To cool the room using the Evoheat 270.
Install the unit so the outlet from the heat pump is blowing INTO the room. The room MUST
have some form of air outlet otherwise the performance of the unit will suffer significantly
To maintain the room at normal temps using the Evoheat 270.
Install the unit so the outlet from the heat pump is blowing OUTSIDE the room. The room
MUST have some form of air inlet otherwise the performance of the unit will suffer
significantly

6.Maintenance and repair
6.1 Maintenance
Check the water supply and air vent frequently, to avoid lack of water or air in the water
loop. Clean the water filter in a certain period to keep good water quality. Lack of water
and dirty water can damage the unit.
Keep the unit in a place which is dry and clean, and has good ventilation. Clean the heat
exchanger in 1 or 2 month and keep good heat exchange rate and save energy.
Check each part of the unit and the pressure of the system. Replace the failure part if
there is any, and recharge the refrigerant if it is needed.
Check the power supply and the electrical system, make sure the electrical components
are good, the wiring is well. If there is any part failed with wrong action or smell, please
replace in time.
If the heat pump is not used for a long time, please drain out all the water in the unit and
seal the unit. Please drain the water from the lowest point of the heat exchanger to avoid
freezing in winter.
Don't power off the unit in low temperature areas to avoid freezing of pipes.
Inspection of the Magnesuim Anode and Draining the unit
Turn off the power to the unit and close the cold water inlet valve to the heater.
Open the drain plug on the bottom of the heater and drain the unit of water. A hot water tap
may need to be opened in the house to allow drainage.
Check the Magnesuim rod every 6 months by unscrewing the rod out of its connection. If
the diameter is less than 5mm and/or the length is less than 200mm replace with a new rod.
Refill the unit as per installation instructions on page 13.

7.Appendix
7.4.CAUTION-1
To reduce the risk of excessive pressures and temperatures in this water heater, install
temperature and pressure protective equipment required by local codes. A combination
temperature and pressure relief valve must be certified by a nationally recognized testing
laboratory that maintains periodic inspection of production of listed equipment or materials, as
meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water
Supply Systems, AS1357.1. This valve must be marked with a maximum set pressure not to
exceed the marked maximum working pressure of the water heater. Install the valve into an
opening provided and marked for this purpose in the water heater. Install the P&T Valve or
provide tubing so that any discharge from the valve exits only within 6 Inches above, or at any
distance below, the structural floor, and does not contact any live electrical part. The discharge
opening must not be blocked or reduced in size under any circumstances.
CAUTION-2
Hydrogen gas is produced in a hot water system served by this heater that has not been
used for a long period of time (2 weeks or more). Hydrogen gas is extremely flammable. To
reduce the risk of injury under these conditions, it is recommended that the hot water faucet
be opened for several minutes at the kitchen sink before using any electrical appliance
connected to the hot water system. When hydrogen is present, there will probably be an
unusual sound such as air escaping through the pipe as the water begins to flow.
There should be no smoking or open flame near the faucet at the time it is open.

7.Appendix
7.5.The method of grounding
Picture 10
7.6.Installation of a P&T valve
P&T valve is used to prevent the temperature or pressure becoming too high inside the tank. When
the temperature or pressure reaches the set value, the valve will open automatically so as to force the
pressure or temperature to decrease.
The handle of the safety valve should be tested once every six months so as to remove the calcium
carbonate deposits and guarantee there is no blockage in the device. Take care to avoid burns for the
temperature of the discharging water is very high.
Vent pipes should be thermally insulated to prevent safety risks caused by freezing pipes in winter.
32
7.Appendix
7.7.Overheating protector
The overheating protector is used to turn the power off, preventing the hot water from being
heated too high. To return the unit to its normal operational status it will have to be re set manually.
Please contact Evoheat for service if this occurs.
Operation details
To access the overheat protector the front dark grey controller panel must be removed. Remove the
3 screws on the front panel and push the front cover upwards.
Then remove the screws covering the overheat protector panel as below..
Remove the screws and open the cover
Press the red button to reset
