Project task:
We were contacted by the owner of a large two-story house with an area of 350 m² with the task of replacing the existing heating system with a more modern and economical one. With the onset of cold weather, heating costs have become significant, so the client decided to switch to a heat pump, as an effective alternative.
After analyzing the object, the optimal solution was selected - a heat pump Raymer RAY-32DS2-EVI power 32 kW, which operates from a three-phase network (380V). This equipment is ideal for large houses, providing both heating, and hot water supply.
Our team installed the system, After all, the house has limited space for a boiler room, which required a precise approach, competent planning and experience with large pumps. In such conditions, it is important not just to install equipment, and do it like this, for the system to work effectively, reliably and without interruption.
Why did you choose a Raymer RAY-32DS2-EVI heat pump for a large house instead of an electric boiler??
For owners of large houses, the issue of energy efficiency and savings – one of the main. Traditional electric boilers consume large amounts of electricity, especially when heating an area of more than 300 м². But the heat pump Raymer RAY-32DS2-EVI – this is a modern solution, which can significantly reduce heating costs. Thanks to inverter technology and high efficiency ratio (COP), he is capable of transforming 1 kW of consumed electricity in 3-4 kW of heat. This means significant savings compared to an electric boiler at the same heat load. Besides, Raymer RAY-32DS2-EVI has advanced control functions, can operate in cooling mode in summer and provides hot water supply all year round.
Stages of installation of the heat pump
1. Installation of Raymer Ray-32DS2-EVI heat pump
When installing the outdoor unit of the heat pump Raymer RAY-32DS2-EVI (380V) we installed it on a metal stand, which was previously fixed on a concrete slab. This foundation is reliable and will not allow the block to sag over time.. It was important to place the block slightly above the ground – so it is protected from snow, rain and moisture.
For installation, we chose a place with free access to air., so that the heat pump can work properly. Also taken into account, so that he does not interfere and does not stand too close to the windows. Copper pipes with thermal insulation were connected to the outdoor unit – this is necessary, to avoid heat loss and condensation. All connections have been carefully checked.
Separately connected power supply – this is a three phase pump, so the power supply is 380V. Certainly, everything was done in compliance with safety regulations. Drainage was also organized, so that excess moisture can be easily removed.
After installation, a test run was carried out – checked the pressure, the temperature, operation of the compressor and fans. The system turned out to be quiet, Stable, ready to work even at sub-zero temperatures.
2. Installation of the hydraulic module of the heat pump Raymer RAY-32DS2-EVI
In this project, our company’s specialists installed the Raymer hydraulic module, taking into account all technical requirements and space ergonomics. The hydraulic module was carefully fixed to the wall, which saved space and provided convenient access to connections. All pipelines are insulated to prevent heat loss, and their laying is thought out like this, to avoid crossovers and ensure a logical connection between all elements of the system.
The hydraulic module is integrated with an indirect heating boiler, expansion tank and plate heat exchanger. An important part of the installation was the installation of the filtration unit – two coarse and fine filters were installed to protect equipment from mechanical impurities and increase the durability of the system. A hydraulic accumulator is installed at the bottom of the system, which ensures stable pressure in the water supply and reduces the load on pumping equipment.
The entire system is designed as neatly and functionally as possible., taking into account future service. This installation approach guarantees reliable and efficient operation of the heat pump and associated components in all operating conditions..
3. Installation of an additional heat exchanger Raymer B3-050-66 on 3.5 sq.m
In this project, our company’s specialists installed an additional plate heat exchanger, which was integrated between the Raymer heat pump hydronic module and the indirect heating boiler.
Purpose of the heat exchanger
Its task is to transfer thermal energy from the heat pump circuit to the hot water supply or heating system, ensuring efficient operation without direct contact of coolants. This is especially true for systems, where hydraulic circuits need to be separated or expensive components need to be protected from possible contamination.
Features of installation
-
The heat exchanger is installed on the wall in a horizontal plane, including service access.
-
All connections are insulated with heat pipe insulation to prevent heat loss.
-
Shut-off valves and drain taps are installed on both sides of the heat exchanger, which simplifies dismantling and washing if necessary.
-
To ensure coolant circulation, two controlled circulation pumps are installed, each on its own side of the heat exchanger.
General integration
The heat exchanger works in conjunction with a hydraulic module, expansion tanks, DHW boiler and water purification system. This approach allows you to flexibly control temperature conditions and increase the efficiency of heating and water heating.
This solution option made it possible to ensure high reliability of the system with compact installation in a small room.
4. Circulation pump in the heating system
For efficient operation of the heating system in this project, it was installed circulation pump Raymer T8-139W. This is a modern equipment with variable speed function, which allows you to automatically adjust the circulation intensity depending on the coolant temperature and user needs. Thanks to this approach, the pump does not work at maximum all the time., which reduces the load on the system, reduces energy consumption and extends equipment life.
The pump is made of nickel-plated cast iron, which provides high corrosion resistance and is ideal for installation in difficult conditions, such as limited boiler room spaces, which were in this case. Its compact size is also an advantage when installing in tight spaces.
Additional advantages of the pump are:
-
Low noise level during operation.
-
Easy setup via electronic control unit.
-
Reliable operation over a wide temperature range.
-
Compatible with underfloor heating and radiator heating systems.
Thanks to the installation of this circulation pump, it was possible to ensure stable and balanced operation of the heat pump Raymer RAY-32DS2-EVI In the house area 350 sq.m. This is an important component, which directly affects comfort, reliability and efficiency of the entire system.
Features of the Raymer RAY-32DS1 EVI heat pump:
Energy Saving
A heat pump is an energy-saving heating solution. Heat pump heating systems can save up to 80% electricity compared to traditional methods. This occurs by using heat from the environment for heating instead of directly producing heat.
Comparative analysis shows, that even in cold conditions the heat pump is able to operate efficiently, providing warmth in the house while reducing energy consumption.

EVI technology
EVI technology (Enhanced Vapor Injection) in the heat pump Raymer RAY-32DS1-EVI is an improved feature, which increases the efficiency and performance of the heat pump, especially in low temperature conditions. EVI technology works by injecting additional steam into the compression process, allowing the heat pump to maintain higher levels of efficiency even when operating in colder climates.
In a standard heat pump, when the outside air temperature decreases, COP, usually, is decreasing. However, with EVI technology, the heat pump can optimize its performance by regulating the refrigerant flow and injecting additional steam. The result is increased thermal output and efficiency, which makes the heat pump more suitable for operation in winter conditions.
