Task: Find an alternative way of heating and hot water supply for a house in the Kyiv region. An electric boiler was installed in the house, as a backup and to save electricity, a solid fuel boiler was added to the boiler room scheme.
Solution: After analyzing the engineering systems of the house and the parameters of thermal loads at the facility, our specialists decided to install an 11.5 kW air-to-water heat pump to the existing heating system.
Result:The installed heat pump covers about 80% of the building’s maximum heat load, taking into account that the electric boiler is switched on on the coldest days. Also, the Customer still has the opportunity to be heated with firewood. In addition, the automation of heating of the hot water supply boiler and recirculation of hot water was installed and brought to the control of the smartphone.

Rising gas and electricity prices often increase household heating and hot water costs exponentially. Even the transition to heating with biomass (solid fuel boiler) does not help, since there is not always access to cheap fuel, and it is not always possible to work as a “stoker”.
We will consider one of such illustrative examples today, where some of the standard energy efficiency solutions have already been adopted by the Customer at the construction stage, but given the constant increase in tariffs, they turned out to be insufficient for acceptable energy bills.

In this case, we were faced with a private house, to which from the energy sources only electricity was supplied. Accordingly, an electric boiler was installed, as a backup and to save energy, a solid fuel boiler was added to the boiler room scheme.
But the cost of firewood has increased sharply over the past year, and electricity consumption is quite high. In anticipation of an increase in electricity tariffs, the Customer set out to find an alternative way of heating and hot water supply at home.
An additional advantage of this house was:
- Measures already taken to insulate the building during the construction phase (what is the right thing to do with any heat source).
- The heating system has been completed with underfloor heating (which allows the heat pump to operate at a higher C.O.P.).
After analyzing the engineering systems of the house and the parameters of thermal loads at the facility, our specialists decided to install an 11.5 kW air-to-water heat pump to the existing heating system.

To reduce capital costs, the heat pump was selected as the main heat source to cover about 80% of the building’s thermal load, taking into account the inclusion of an electric boiler on the coldest days (below -5 … -10 ℃). Also, the Customer still has the opportunity to be heated with firewood, if there is time and an acceptable price for this raw material.
The entire system was configured to work automatically with the ability to remotely control the heat pump via the Internet from a smartphone (with iOS or Android).
In addition, the automation of heating of the hot water supply boiler and recirculation of hot water was installed and brought to the control of the smartphone,which allows you to turn on these systems as needed or at night at a reduced rate.
The main parameters of the system:
- Location – Kyiv region, Kyiv-Sviatoshynskyi district;
- Heat pump – MyCond MHCS 040 AHS with DC inverter;
- Heat pump type – “air-to-water”;
- Nominal conversion rate (C.O.P) – 4.71;
- Average annual conversion rate (С.О.Р) – 3;
- Power supply – 220…240V/50Hz;
- Rated power consumption (heating nom./max.) – 1,73/3,03 kW;
- Refrigerant – R410A;
- Internet connection – via Wi-Fi module;
- Ambient operating temperature range – -25…+46 ℃;
- Payback period of the solution – up to 5 years.
Services of the company Alteco:
- pre-project analysis, issuance of estimates and payback of the solution;
- design work and issuance of specifications;
- supply of equipment and materials;
- heat pump installation;
- start-up of a heat pump and adjustment of automation;
- service, guarantee.
As we can see, new technologies will always come to the rescue in solving a problem only with a professional approach to their application.
To install a heat pump, it is necessary to analyze many parameters, since this equipment may not be suitable for every heating/cooling system.
The exception is new construction, where at the project stage (if the designer keeps up with the times) all modern solutions can be envisaged.
Also, the efficiency of the equipment will depend on the quality of calculations and installation of those specialists who undertook this.
The Alteco company installs heat pumps only from trusted manufacturers, subsequently for which we will be able to provide service and warranty support. We perform engineering calculations using modern software, which subsequently ensures reliable and long-term operation of the equipment.
Our team of specialists offers complete solutions for private and commercial properties to save or generate energy from renewable energy sources.
