Exercise
For a new house with an area of approx. 100 m² customer was looking for a modern and economical heating and cooling solution. Basic requirements - efficiency, compactness of the equipment due to the limited space in the boiler room and the ability to provide the house with hot water. The versatility of the system was also important: so that it can work not only for heating in winter, but also for cooling in summer.
Answer
Под руководством наших инженеров был смонтирован тепловой насос Raymer RAY-10MN power 10 kW, ideal for homes up to 100 м². Из-за ограниченного места в котельной применили гибридное решение – Raymer tank 245 L indirect heating DHW180L + buffer 65 L stainless steel, which simultaneously provides hot water supply and stabilizes the operation of the heating system. Для равномерного распределения тепла и кондиционирования установили фанкойлы Daikin FWT02GT, которые позволяют комфортно пользоваться системой круглый год.
1. The first stage is installation of the external unit
Первым шагом стала установка наружного блока теплового насоса Raymer RAY-10MN. It was placed in the yard, in a convenient place, which ensures unobstructed access for maintenance and good air circulation.
A feature of this stage was the length of the freon route - about 7 meters. For aesthetics and protection of communications, it was carefully laid underground. Pipes insulated, which guarantees reliable operation and preservation of energy efficiency even in difficult weather conditions. This approach allowed us to save space in the yard and make installation as neat as possible..
It is important to note, What in this case, a monoblock system is used. It means, that all the key elements are the compressor, the heat exchanger and automation are located in the same housing of the external unit. This makes installation much easier, because there is no need to lay long freon routes between the external and internal units, and all connections are made only through water communications. This approach not only speeds up the installation process, but also increases the reliability of the system and facilitates its further maintenance.
2. Installation of the Raymer G180/65 combination tank (DHW 180L + Buffer 65L)
In this project, for a boiler room with limited space, it was decided to use a Raymer G180/65 combination tank. Its design combines two main components in one housing:
Hot water tank (DHWP) – 180 liters.
This volume provides a stable supply of hot water for the needs of a family from 3-5 Human, allowing you to comfortably use the shower, kitchen and other water points.
Buffer capacity – 65 liters.
It functions as a hydraulic stabilizer for a heat pump:
- reduces the number of compressor starts,
- protects equipment from overload,
- accumulates part of the thermal energy and ensures smoother operation of the heating system.
Features of installation
Due to the limited space in the boiler room, using a separate DHW boiler and buffer tank would not be possible. Therefore, the hybrid model became the optimal solution, allowing you to save space without losing functionality.
The tank connection is made taking into account two circuits: контур горячего водоснабжения и отопительный контур с буферной емкостью.
The tank is integrated into the heat pump system, which allows you to maintain a high level of energy efficiency and stable hydraulic balance.
All connections are made with high-quality thermal insulation, which reduces heat loss and increases overall efficiency.
Advantages of using this particular model
-
Compactness. Две емкости в одном корпусе экономят место в техническом помещении.
-
Heat pump protection. Буферная часть уменьшает количество запусков компрессора, extending its resource.
-
Comfortable DHW. Наличие бойлера на 180 liters provides the family's needs for hot water even during peak hours.
-
System elasticity. Модель легко интегрируется в разные схемы отопления (radiators, warm floor, fancoils).
3. Installation of Daikin FWT02GT fan coil units
В данном доме для обеспечения комфортного микроклимата были Daikin FWT02GT fan coil units installed. These are modern climate control devices, which work in conjunction with a heat pump and perform two key functions: efficient heating of the room in winter and cooling in summer. Thanks to their compact size and stylish design, fan coil units fit harmoniously into the interior, while ensuring even distribution of heat or coolness throughout the house.
Daikin fan coils are quiet, high energy efficiency and flexible fan speed settings. This allows home owners to maintain a comfortable temperature at any time of the year with minimal energy consumption. Installing such devices in combination with a heat pump has become the optimal solution for a complete heating-cooling system, which works stably and as economically as possible.
4. Voltage stabilizer for protection against voltage surges
A voltage stabilizer was installed in the building even before the installation of the heat pump began.. This decision became an important component of the entire system, since the stabilizer provides protection against power surges and guarantees safe and stable operation of the equipment. It equalizes the voltage in the network, thanks to which all devices from household appliances to complex heating and automation systems work without failures.
The stabilizer extends the service life of equipment, protects against the risk of breakdowns and ensures continuous operation even in cases of, when critical surges or voltage sags occur in the network. Thus, its presence was an additional guarantee of the reliability of the entire engineering system of the house.
The pre-installed stabilizer in the house was sufficient to protect household appliances and standard equipment, however, its power was not enough for the full operation of the entire system, taking into account the new heat pump. Heat pumps have high energy consumption and are particularly sensitive to voltage fluctuations, therefore there was a need for a more powerful solution.
To this end система была усилена дополнительным стабилизатором напряжения Элексом Ампером. This is a modern device, designed for stable operation with powerful electrical consumers. Not only does it maintain optimal heat pump voltage, but also takes on the load of the entire engineering system of the house. As a result, we managed to achieve maximum reliability: Heat pump, the solid fuel boiler and other equipment now operate without the risk of interruptions, which is especially important in conditions of an unstable power grid.
Benefits of using the Raymer RAY-10MN monoblock (10 kW)
Monobloc Raymer RAY-10MN power 10 kW - an excellent solution for houses or cottages of medium size. It combines a number of advantages, which make it a profitable choice for property owners.
Energy efficiency and savings
The monoblock operates using inverter technology (if the model is equipped with an inverter compressor), allowing it to adjust power depending on current needs, instead of constantly consuming the maximum. This reduces energy consumption, reduces electricity bills and reduces equipment maintenance costs. When the system is properly configured, heating occurs faster and more efficiently.
Easy installation and minimal infrastructure costs
Monoblock means, that the external and internal elements of the heat pump are combined in one housing or that the external unit contains all key functional units. This eliminates the need for large backbone infrastructure inside the home. As a result, the costs of time and materials for laying pipes are reduced, heat exchangers, freon routes, etc.. d. Installation of a monoblock is easier compared to a split system, especially in private houses or cottages with limited space.
Reliability and minimum heat loss
The monoblock minimizes the length of freon or other lines, which reduces heat loss, probability of leaks and insulation costs. This also reduces the risk of malfunctions, associated with wear of connections or hoses, especially during sudden temperature changes or vibrations.
Comfort and stability
Raymer RAY-10MN ensures maintaining a comfortable temperature in residential areas, with the ability to work as with “warm floors”, as well as with traditional radiators - depending on the features of the system. Inverter models allow you to smoothly regulate the temperature, work almost silently and quickly reach the specified mode.
Reduced costs for backup heat sources
The monoblock can act as the main source of heat during the heating season, reducing the need to use generators or electric boilers. If there is a stable power supply, the owner can significantly reduce the cost of additional energy sources, resorting to them only at peak or emergency times.
Environmental friendliness
Heat pumps are generally more environmentally friendly, since they use the thermal energy of the environment instead of direct combustion of fuel or the operation of electric heaters. This reduces CO₂ emissions, especially if the electricity comes from renewable or cleaner sources.
