Project task
The owner of the house is square 170 M² made a clear request - reduce heating costs, which increased significantly every heating season due to the use of an electric boiler. Despite sufficient effectiveness, Direct heating of electricity was too expensive in the long run. At the same time, it was important to maintain comfort in the house without loss of heat and avoid complex redevelopments or dismantling the existing system.
Answer
The best option was the replacement of an electric boiler with a heat pump for the air-water Raymer Ray-15DS2-EVI power 15 kW. This inverter equipment can work effectively even at low temperatures, significantly reducing electricity consumption due to the high transformation coefficient (COP).
The owner performed the installation of the heat pump on his own, which additionally saved on the cost of installation. All elements are an external block, Freon highway, hydraulic module, buffer capacity and dowry tank - were integrated into an existing heating system without the need for its radical reconstruction.
As a result of the implementation of the project, the house received a modern, Energy efficient solution, which provides stable thermal comfort, autonomous work and a significant reduction in monthly expenses heating.
1. Outdoor unit installation
In the process of implementing the project Particular attention was paid to the installation of the outer block of the heat pump Raymer Ray-15DS2-EVI. Due to limited conditions in the surrounding area-namely, a narrow passage between the house and the fence, And also that, that the wall of the boiler room directly borders on the fence - The classic version of installing the block on the concrete base near the facade was impossible.
After the analysis of the options, an engineering justified decision was made - Raise the outer block higher and mount it on the brackets directly to the wall of the house, above the level of fence. This location allowed:
- ensure free circulation of air around the heat exchanger;
- maintain access to the outer service unit;
- Avoid obstacles to removing condensate;
- maintain the integrity of the courtyard and not sacrifice a useful space.
This approach made it possible to safely and effectively integrate the external unit into existing conditions without compromises on the functionality or reliability of the system.
2. Installation of the indoor unit
As part of the implementation of the project for the installation of a heat pump Raymer RAY-15DS2-EVI In the house area 170 M² special attention was paid to competent integration of a hydraulic engine in an existing heating system. Since the house is equipped with a radiator system, working on the basis of an electric boiler, It was decided to leave an electric shock in the system as a backup heat source. This allows you to ensure additional reliability of heating in the case of extremely low temperatures or maintenance of main equipment.
The hydraulic engine was installed in the boiler room and connected in parallel to the existing electric boiler using a correctly organized hydraulic strapping. This circuit allows the heat pump to work autonomously, At the same time, ensuring the possibility of automatic or manual switching to a backup heat source if necessary.
For stable and balanced operation of the system The hydraulic engine was connected to the buffer capacity, which ensures the accumulation of thermal energy and evens out temperature fluctuations in the radiator circuit. Besides, The system also includes an indirect heating boiler for hot water supply, with which the hydraulic engine is connected through a three -way valve. Thanks to this, the coolant is sent by priority or to heating the hot water, or in the heating system, which allows you to effectively distribute the water pump resources.
This approach ensured a full integration of a modern heat source into an existing system without cardinal changes in infrastructure, and also created a flexible, a reliable and economical scheme of heating and hot water supply.
3. Installation of the buffer capacity Raymer IMP 150 liters and indirect heating boiler Raymer DHWP 150 liters
The project also installed buffer capacity Raymer IMP volume 150 liters and an indirect heating boiler Raymer DHWP volume 150 liters. Given the dimensions of the equipment and the need to provide convenient access to it for subsequent maintenance, was It was decided to place both tanks in a separate adjacent room, located next to the hydraulic engine.
Such planning allowed to unload the main technical room and provide free space for circulation pumps, pipelines and electrical connections. Besides, Thanks to this placement, installation and subsequent maintenance of equipment can be carried out without difficulty even when modernizing the system.
For stable operation of the system, there were also expansion tanks for each of the tanks have been installed - Separately for buffer capacity and separately for a hotel boiler. This allows you to compensate for the temperature fluctuations of the volume of water in each circuit, prevent excess pressure in the system and ensure uninterrupted operation of equipment.
In addition to installing expansion tanks, On each of the storage tanks - the buffer capacity Raymer IMP 150 and boiler DHS Raymer DHWP 150 — full -fledged security groups were mounted.
Each security group includes:
– safety valve Dressing pressure, which prevents exceeding the permissible pressure in the tank, automatically discarding excess water during overheating or hydraulic boards;
– Automatic air vent, allowing air from the system, preventing the formation of air traffic jams;
– manometer, providing pressure control in real time.
Installation of such security groups is mandatory When using hermetic systems with storage tanks, since they provide stable equipment and protect the system from emergency situations. In this installation, these components are installed directly near each of the tanks, what simplifies their control and maintenance.
The benefits of mounting the RAY-15DS2-EVI heat pump for a client
The installation of the heat pump has become economically profitable and strategically correct solution for the owner of this house for several key reasons:
1. Significant decrease in heating costs
Previously, the house was heated by an electric boiler, which consumed a large amount of electricity, especially in the cold period. The heat pump RAY-15DS2-EVI works on the principle of converting the energy of outdoor air into heat, consuming a minimum of electricity. Compared to direct electric shift, Thermal pump allows you to reduce costs 3-4 times, which is especially relevant at the current tariffs.
2. Energy efficiency at the level of modern housing
House area 170 sq.m is equipped with a radiator heating system, Therefore, the choice of an inverter heat pump with the possibility of connecting to the existing system allowed save previous investments in infrastructure and at the same time achieve a high level of energy efficiency.
3. The possibility of using a reserve heat source
The electric boat was left in the system as a reserve. Such a hybrid scheme provides reliability and the calmness of the owner - in the case of failures or extremely low temperatures, the system can automatically switch to a backup source.
4. Increasing comfort due to automation
The modern heat pump allows you to accurately adjust the temperature, operates automatically, can be integrated into the Smart House system, It is controlled remotely. It means Less intervention in the heating process and more stability and convenience In everyday life.
5. Hot water heating
Due to the connection to the DHW Baku, the heat pump also provides Hot water heating, Reducing the need for individual electric water heater. Hot water is now available from the same energy -efficient source.
6. Investment with a long -term effect
Despite the initial costs of equipment and installation, The heat pump is Long -term investment, the payback of which is usually 3-5 years. After that, the owner begins to receive real financial benefits.
7. Independence from the growth of tariffs and energy prices
The heat pump uses a renewable energy source - air, which reduces dependence on gas prices for gas and electricity. In combination with the possible installation of solar panels in the future - this is another step towards energy autonomy.
Thus, The installation of the heat pump allowed not only reduce monthly expenses, but also increase Comfort and stability level, Creating reliable and modern heating and hot water supply system.
