Warning: The Compact Type heat pumps have a hydraulic connection, which means that the medium in the pipes (water or a mixture of water and concentrate antifreeze) can freeze if the heat pump is not under voltage for a longer time. This may cause major damage to the heat pump and on the system itself. For further information, please contact an authorized Installer or Gorenje HVAC.

2 PRINCIPLE OF OPERATION OF THE HEAT PUMP

2.1 THE BASIC PRINCIPLE OF OPERATION OF A HEAT PUMP

A heat pump operates similarly as a refrigerator. In a refrigerator, liquids evaporate due to received thermal energy from the surrounding air and this energy is emitted at a desired spot during condensation (Carnot’s cycle). A heat pump works in the opposite direction: it accepts thermal energy from the surrounding air and emits it in heated premises, using the natural heat collector of the environment. Ground and surface water, earth’s warmth, solar energy and ambient air can be used as energy sources. The system is composed of four units: evaporator, compressor, condenser and damper. Heat energy is transferred via the coolant. In the evaporator, the coolant receives heat energy and evaporates. In the compressor, the vapour is compressed, which makes it heat up intensively. This hot vapour transmits thermal energy from the condenser to the heating water and liquefies. In the damper, the coolant expands (pressure reduces to the starting pressure, from there it proceeds to the evaporator and the cycle repeats).

2.2 INVERTER HEAT PUMP

Inverter heat pumps use variable-speed compressors. Traditional heat pumps use fixed power/rotation speed compressors. In inverter compressors, the compressor speed constantly adapts to the heat losses of the room and the energy value of the source (air, brine or water, depending on the system). In traditional heat pumps, the power of the compressor is always the same. Compressor starts with full power and when it achieves the desired values/temperatures, it shuts off and waits until it restarts. Inverter heat pumps work for a longer period of time, but with lower power (adjusting to the premises), which means lower consumption of electric energy.

2.3 OPTIMISATION OF HEATING COSTS

2.3.1 Selection of heat pump

The first step towards the optimisation of heating costs is selecting the appropriate heat pump. An over-dimensioned or under-dimensioned heat pump can cause higher heating costs and shorten the lifespan of the appliance.

2.3.2 Heating curve

A correctly set heating curve is of key importance for the optimisation of heating costs. If a room thermostat is used, the heating curve must be adjusted to the building as if it was not existent. A too highly set heating curve can cause up to 30% higher heating costs!

2.3.3 Domestic water

Incorrect or too highly set desired temperature of domestic water can significantly increase heating costs! In a traditional system with a 100-litre boiler, where domestic water is heated by a heating element, the temperature necessary for meeting the needs of an average family is much higher than in a system where domestic water is heated by means of a heat pump. The difference lies in the quantity of the water in the water storage tank. With heat pumps special water storage tanks are used that have a larger volume than traditional boilers! For a heat pump system, daily consumption of 50 litres is assumed, multiplied by the number of users of domestic water.

Example:

Family of four – 4 persons x 50 litres = 200 litres

2.3.4 In time of absence

Complete shutdown of a heat pump can lead to higher heating costs. We recommend using the vacation mode, which lowers the temperature of heating and domestic water during your absence, but does not allow the system to get completely cold, which would cause higher heating costs upon system restart. The next chapter describes how to make small steps to save a lot of energy.

3 HOW TO MAKE SMALL CHANGES TO

REDUCE HEATING COSTS

 Every degree counts!

The use of heating energy depends on the temperature of the room. In a heated apartment, every degree above 20 means up to 6 % higher energy use, i.e. higher cost.

 All windows and doors must be properly sealed!

Old windows and doors are usually not completely sealed, so draft takes warmth out

of the apartment. If crannies are visible, it’s crucial to take action as soon as possible.

Try to solve the problem by sticking sealing tapes on the contact surfaces or cut notches for plastic sealing profiles / set the hardware or seal the internal casements in classic (box) windows with separate casements.

 Correct ventilation!

To feel good we need enough oxygen in the air, and we can get fresh air by means of ventilation. If done correctly, we use up to 20% less energy for heating. Ventilate by opening the window for a few minutes. Do this three times per day in each room. The lower the temperature of ambient air, the shorter the ventilation should be.

 Do not cover heating elements!

If heating elements are covered, air pockets occur that waste energy. It is recommended to have curtains that only reach the level of radiators. Covering heating elements can increase energy use by up to 10 %.

 Set the appropriate temperature!

Is your heating regulation set to automatic or do your kids use it? If you want to select the correct temperatures for your living environment, please consult with experts who will tell you what temperature is the best for each living space. Already two degrees – 22 degrees instead of 20 – can cause 12 % higher energy consumption!

 Check the possible causes for high energy consumption related to heating

If you think that you are using excessive amounts of energy, it is advisable to check among the multiple causes for high heat losses:

– Old radiator valves (where thermostat valves are not built in); – Poor or damaged heat insulation on internal installations after the measuring

point;

– Poorly maintained internal installations; – Decrepit or improperly set temperature regulation automatics; – Poor heat insulation of buildings (esp. older ones); – Poorly sealed windows (especially without insulated glazing);

– Incorrect ventilation of premises (when ventilating rooms, make sure the

radiators are closed);

– The charged quantity of used heat for central heating of premises depends

mainly on the average outside temperature, so the consumption increases in the start of the heating season, usually achieves the highest value in January, and decreases at the end of the heating season;

– Longer accounting period than usual – may be caused by the inability to read

the status in the regular period, or if the ownership transfer documents arrived too soon etc.;

– Incorrect operation of the measuring device; – Status for the period of defect of the measuring device was determined based

on statistics.

 Installation of heat cost allocators or calorimeters

If your apartment is in an old apartment building and you are paying for heat energy consumption per square meter (flat rate), you can install heat cost allocators on individual radiators in your apartment or, depending on the building, a calorimeter before heating enters the apartment. In this case you can save heat energy independently of your neighbour. However, in order to do this, more than one half of apartment owners must be in favour of this with respect to the Rules on dividing and billing heating costs in multiple-dwelling buildings. This way an individual apartment building can save between 20 and 30 % of energy.

4 EMERGENCY OPERATION

Emergency operation is the operation of a heat pump with auxiliary heating sources such as electric heaters, gas furnace, oil furnace or other heating source controlled by the heat pump. Emergency operation is divided into Automatic and Manual operation.

Automatic Emergency Mode:

If the control detects that it cannot run the heat pumps as sources of heating due to possible errors, additional heating sources for heating system and heating sanitary water will be automatically switched on. Note: the current Heating and DHW set temperature is automatically reduced by 7°C.

Manual emergency mode:

Activating this mode is a responsibility of the end user. This method is used in the event of a failure of the master controller when it cannot control the system. The heat pump has a manual switch to activate the manual emergency operation (the signal light on the switch lights-up when it is activated). At this moment, all settings on the main controller become invalid, because the control of the desired temperatures is exclusively controlled by the additional thermostats that are installed on the device.

On the digital thermostat, set the desired heating temperature and the desired DHW temperature on the mechanical thermostat.

Note: If the Digital Thermostat is manually switched OFF, so that on teh screan are three red lines - - - , the Automatic emergency operation will be disabled.

Emergancy switch in OFF position – Heat pump works according to teh settings on the

main controller (tuch-screen controll panel)

Emergancy switch in ON position – Setting of teh main controller (tuch-screen controll panel) will be disabled. All Circulating pumps (P0, P1, P2 an P3) start to work (always ON). Temperature controll is only with Digital thermostat (controlling the set temperature of electrical heaters). Diverting valve has to be set manualy to switch from Heating system to DHW heating.

1. Digital thermostat controls the max flow temperature in case of Back-Up or Auto–

Emergency operation. In the Back-Up and Auto–Emergency operation, the Main controller is still controlling the heating temperature.

Auto – Emergency operation

Example: If the Unit turns ON the Back-Up heaters or Emergency operation and the setting on

the Digital thermostat is set to 30°C, the heaters will work only until 30°C and then

switch OFF regardless of the demand from the main controller. If, however the Digital thermostat is set to 60°C, the Main controller will switch OFF the heaters according to its needs.

Manual operation (manual emergency switch ON): In manual operation all the circulating pumps are switched ON and the Electrical heaters work according to the setting on the Digital thermostat, regardless of the setting on the Main controller. Example: if the Manual emergency operation is ON and the temperature set on the Digital

thermostat is set to 50, the heating water will be heated to 50°C. The Circulating

pumps will run all the time.

2. Analog thermostat controls the max flow temperature in case of Back-Up or Auto –

Emergency operation for DHW. In Back-Up and Auto–Emergency operation, the Main controller is still controlling the DHW temperature.

Auto – Emergency operation

Example: If the Unit turns ON the Back-Up heaters or Emergency operation for DHW and the

setting on the thermostat is set to 40°C, the heaters will work only until 40°C and then

switch OFF regardless of the demand from the main controller. If however the thermostat is set to 60°C, the Main controller will switch OFF the heaters according to its needs (DHW set temperature).
