After that:
- neatly disconnected the boiler from the electric network;
- Dismantled power cables, Following the safety of insulation and correct marking for further use in the new system;
- removed the connection with the heating pipeline system;
- They removed the boiler itself from the wall mount, avoiding damage to the decoration in the room.
The condition of the pipes was also checked, to which it was planned to connect the heat pump. If necessary, local replacement of fittings and a crossroads of areas for compatibility with new equipment were carried out.
3. Installation of the indoor unit: Integration of the heat pump into an existing heating system
After dismantling the electric boiler and preparing the room, the next step was Installation of the internal unit of the heat pump Raymer Ray-15D2MN-EVI. This stage was critical, After all, it is the internal module that provides the distribution of thermal energy by the system and interacts with the coolant in the circuit of the house.
The installation site was chosen the same, where the electric boiler was previously — in a technical room with easy access to main highways and power grids. This has reduced the installation time and reduce the amount of necessary changes in the wiring.
The main stages of installation:
Block mount to the wall. The unit was installed on anti-vibration mounts to reduce noise during operation. The area of the premises made it possible to provide a sufficient gap for service from all sides.
Connection to the hydraulic system. The indoor unit was connected to the existing heating system, taking into account the hydraulic characteristics. For this, high -quality fittings and insulating materials were used. Also installed filter of rough cleaning and locking reinforcement for ease of operation.
Electrical work. The power connection was carried out taking into account safety requirements: A separate machine, Protective grounding, Proper phase load. The system was connected to the control controller with the possibility of integration into the Smart House.
Recirculation and safety circuit. A circuit with an expansion tank is installed, security group and air vent for stable and safe work.
First launch and testing. After filling the system by the coolant and testing for tightness, a trial launch was carried out. The system reached the nominal mode without failures, pressure and temperature corresponded to the norm.
4. Installation and connection of buffer capacity: Stability and efficiency of the system
To ensure stable operation of the Raymer RAY-15D2MN-EVI heat pump and Optimize its inclusion/off cycles, was added to the system buffer capacity Keplobak 80- an important element for the effective and durable functioning of the hydraulic circuit.
The volume of buffer container is selected in accordance with the thermal load of the house and the characteristics of the pump. In this case, for the area 150 m² - this allowed to maintain thermal inertia, reduce the number of compressor launches and increase the overall comfort in heating.
The main stages of installation:
Placement of buffer capacity
The capacity was installed in a technical room next to the inner unit. The floor was previously fortified, And the place is chosen like that, to provide easy access for service. High -quality thermal insulation was used to reduce heat loss.
Connection to the hydraulic pump of the heat pump
The input and output of the buffer container are connected to the hydraulic engine using heat -insulated pipelines. In this case, the direction of the flow of the coolant to ensure the correct circulation is taken into account.
The locking reinforcement has been installed, Ball cranes, Fliment valves and expansion tank, which makes it easy to serve the system in the future.
Hydraulic denouement
The buffer container also performs the function of a hydraulic separator - it avoids conflict between the pump pump pumps and the circulation pumps of the heating system. This is important for achieving stable pressure and uniform distribution of heat in all zones of the house.
Integration into the heating circuit
The exit from the buffer container is connected to the main contour of the heating of the house. For better temperature adjustment, temperature sensors and automatic regulator are installed, controlling temperature depending on weather conditions or internal climate.
