The main task was to install more economical and modern equipment, which would provide stable heating throughout the heating season with minimal utility costs.

Answer:

After analyzing the presented data, it was decided to install a Raymer RAY-18DS1 EVI inverter heat pump, which, thanks to its technology and high efficiency coefficient, can provide significant savings on heating.

So, how a heated floor heating system will be installed in the house, then for cooling, our specialists recommend installing additional fan coils to cool the premises in summer.

Hot water supply will be provided by installing a Raymer DHWP indirect heating tank 200 l.

To increase the reliability and safety of the system, it was also decided to install an expansion tank and a pump group.

This will allow you to maintain stable pressure in the system and avoid possible emergency situations.. Heat pump control was configured via Wi-Fi, which provides ease of use and the possibility of remote control.

Scope of work completed

After analyzing the house design, location of adjacent communications (water, electricity, sewage) a thorough installation plan for the heating equipment has been developed and a location has been selected with the appropriate requirements for the proper operation of the heat pump and all auxiliary system components.

1. Selection of equipment taking into account the climatic conditions of the area

Considering, that the climate in this area has become somewhat milder in recent decades, but from time to time the temperature can still reach up to -25 °C it was decided to install a Raymer RAY-18DS1 EVI inverter heat pump, which easily adapts its work to weather conditions and is able to work at temperatures -30 ° C.

2. Outdoor unit installation

The outdoor heat pump unit was installed on a secure foundation, which ensures the stability of the structure. The location of the outdoor unit has been taken into account to ensure optimal performance and ease of maintenance.

Because, The heat pump has a good external coating, protected from corrosion there was no need to install additional protective structures to protect against adverse weather conditions.

3. Installation of the indoor unit

The indoor unit of the Raymer RAY-18DS1 EVI heat pump was installed in a dry, ventilated room with maximum comfortable access for maintenance.

Freon pipes from the outdoor unit were connected, as well as pipes for hot water supply and storage tank with insulation to prevent condensation formation.

Connected and configured touch controller for heating control, cooling and domestic hot water.

A modem is installed to control the VT remotely from a phone or any gadget, which supports Wi-Fi.

4. Providing hot water supply

Hot water supply was also immediately installed before putting the house into operation.

So, as a heat pump RAY-18DS1 EVI has the ability to connect and control DHW, without thinking for a long time, it was decided to purchase a Raymer DHWP indirect heating tank 200, Made of stainless steel and has a long service life, unlike conventional steel boilers. And a 20-meter coil inside the boiler promotes efficient heat transfer, providing fast heating and constant supply of hot water.

5. Installing additional system components

The heating system requires the installation of additional tanks to maintain a stable temperature of the coolant in the system.

For correct operation of the heat pump in heating mode, cooling, it is recommended to install a storage tank, thanks to which there will be many advantages: defrosting function - hot water supply, additional energy savings in the off-season, sediment from the system will be in the tank, not in the heat exchanger, function of a large hydraulic arrow - the pump does not like cold reverse circulation, for this he needs a mixer, the function of which is performed by the storage tank.

For this project it was enough to install a Raymer IMPOSOL storage tank 100 liters, based on calculations of the length of the heated floor route in the house.

An expansion tank is also installed on 5 l for receiving excess water, occurring during thermal expansion of a liquid due to heating.

In this system of the heat pump Raymer Ray-18DS1 EVI, a three-way valve and a circulation pump are installed, performing important functions for the efficient operation of the heating and hot water supply system:

Three-way valve distributes coolant flows between different circuits - between heating and hot water supply tank (DHW). Switches coolant between different zones. When, when heating of the DHW boiler is required, the valve redirects the flow from the heating circuit to the boiler, and after heating it returns to heating the premises.

Circulation pump ensures coolant circulation in the system, as for heating, as well as cooling. Constantly moves coolant through the heat pump heat exchanger and throughout the system. This allows for even heat distribution (or cold) by premises, and also ensures efficient heat transfer to the heated floor, radiators or fan coils and hot water tank.

Together these components ensure efficient operation of the heating system, switching between modes and stable coolant circulation.

6. Using fan coil units for cooling and additional heating

So, As a heat pump, it is quite a universal thing in providing indoor microclimate, which allows not only to heat, but also to cool the house, our craftsmen installed wall-mounted fan coil units MHW 27 and MHW 35, which will work for cooling in the summer. This eliminates the need for additional installation of air conditioners., which significantly saves homeowners money.

Thanks to the presence of a water heat exchanger, the fan coil can work both for cooling, and for heating the room. This makes it ideal for maintaining a comfortable temperature no matter the weather conditions..

7. Connecting voltage stabilizers

To ensure safe and reliable operation of the heat pump, voltage stabilizers Stabex VS-10KVA were installed. This device protects the system from power surges and other possible power supply problems..

In case of possible blackouts during certain periods of the year voltage stabilizer is necessary in heating systems, powered by generator or batteries.

8. Testing and setting up the system

After completion of installation, a thorough check of the entire system was carried out. Experts tested the operation of the heat pump in various modes, configured settings for optimal performance and ensured all components are connected and functioning correctly.

9. Instruct the client

After completing all the work, the specialists provided detailed instructions to the client on the use and maintenance of the heat pump. The client received all the necessary knowledge to effectively use the new heating system and save on energy costs.

Features of the Raymer RAY 18DS1 EVI heat pump:
