Project task:
The main goal of the project was to install a new heating source in the house before 100 sq. m, which would save money on heating, but would remain effective at very low temperatures even in temperate climates, which has become somewhat milder and rainier in recent decades. Also, the equipment should fit well with the underfloor heating system and provide hot water supply.
Equipment miscalculation:
After analyzing the existing floor heating system, energy efficiency at home, insulation thickness, heating quadrature, it was decided to install a Raymer RAY monoblock-07MN, which has sufficient power to provide heating, subject to the installation of cooling and hot water supply fan coils.
The procedure for carrying out installation work
1. Installation of the outdoor unit
The first stage of installing the Raymer RAY monoblock-07MN is the choice of location, which would be adjacent to the boiler room in the house and would simplify the laying of the pipeline through the wall of the house with a reduction in heat loss during pump operation.
The heat pump is installed on a homemade stand and anti-vibration mounts, reducing the impact of vibration during fan and compressor operation on other parts.
A direct and reverse coolant supply line was laid from the heat pump to the buffer tank, which is located in the boiler room.
The heat pump is powered with appropriate moisture protection.
2. Connecting a buffer tank.
So, How does home heating work based on water heated floors?, you just need to install a buffer tank to accumulate and store coolant in the system.
Tank capacity up to 100 l is quite enough to accumulate coolant in the system for a heated floor area of up to 80 м².
The buffer tank was installed near the heat pump through an adjacent wall, to minimize heat loss and ensure ease of connection.
Connection to the heat pump
Hot water inlet: From the heat exchanger of the heat pump, the coolant is supplied to the upper part of the buffer tank through the corresponding pipe. This allows hot water to be stored at the top of the tank.
Reverse flow: There is a return flow of coolant from the bottom of the buffer tank, which returns to the heat pump for further heating.
This circuit ensures continuous circulation of coolant between the heat pump and the buffer tank, allowing efficient heat storage.
Connection to a heated floor system (comb)
Login to the heated floor system: The supply of hot water from the buffer tank goes to the heated floor comb. The top pipe on the hot flow tank is used, to ensure sufficient temperature for underfloor heating.
Reverse flow from comb: The cooled coolant returns to the lower pipe of the buffer tank after passing through the underfloor heating pipes.
This circuit ensures a stable flow of coolant into the underfloor heating system and uniform distribution of heat throughout the rooms.
3. Installing a circulation pump
To ensure efficient circulation of the coolant, a circulation pump was installed between the buffer tank and the heated floor system. It helps maintain constant pressure and optimal coolant flow rate.
4. Three-way valve
To control the temperature between different circuits, For example, DHW and underfloor heating, a three way valve was installed, which automatically switches the coolant flow between circuits depending on temperature requirements.
6. Thermal insulation
Once all components are connected, it is important to ensure that all pipes are thermally insulated to minimize heat loss and increase the energy efficiency of the system.
7. Setting up and starting the system
After connection, you need to configure the heat pump parameters, circulation pump and temperature conditions for the buffer tank and underfloor heating system. The system was launched and checked for stability.
This connection scheme allows for stable heating of the room., accumulating excess heat in a buffer tank and evenly distributing it through the underfloor heating system, which increases overall heating efficiency.

Conclusion: benefit for the client
Installing a heat pump, the customer receives a number of benefits, which make this heating option attractive and efficient:
Energy savings: The heat pump uses energy from renewable sources, such as air, water or soil, which allows you to significantly reduce heating costs compared to traditional gas or electric systems.
energy efficiency: Heat pumps have a high energy conversion rate (COP), which means, that they can generate more heat, what they consume electricity. This makes them one of the most efficient heating systems.
Versatility: A heat pump can do more than just heat your home in winter, but also to ensure its cooling in the summer, which reduces the need for air conditioning.
Environmental friendliness: Using heat pumps helps reduce CO2 emissions and dependence on fossil fuels, which has a positive impact on the environment.
Independence from fuel prices: Because the heat pump uses energy from the environment, the customer is less dependent on fluctuations in prices for gas or other traditional energy sources.
Comfort and automation: Modern heat pumps are equipped with automatic control systems, allowing you to customize them to individual needs and provide stable comfort in the home.
Long service life: Heat pumps are known for their durability, which allows you to use the system without the need for frequent repairs or replacements.
Thus, the customer receives effective, reliable and economical heating and cooling system, which is also environmentally friendly.
