Thermodynamic heating system


Traditional water heating, in my opinion, has a number of disadvantages associated with the unpredictability of prices (this is the case with gas) and the lack of continuity of the cycle (when they heat with wood or coal).

It is possible, of course, to install a boiler with a continuous supply of pellets, however, a separate and capacious pantry is required for their storage.

But other types of heating have no less disadvantages, they just lie in a “different plane”. So what do you choose?

Twelve years ago I got acquainted with the then new system called «heat pump» (earth — water). I really liked the innovation, but … very cumbersome. I am already silent about the price, which, at a rate of 5.5, cost about 110 thousand UAH. (20 thousand green American presidents).

Solar collectors were more affordable at that time, but even here glass vacuum tubes had a strange effect on the subconscious, which whispered: “wait…”

But visiting the exhibition this year made me very happy and gave me hope for a “warm future”, which is called THERMODYNAMIC SOLAR SYSTEM.

This heat pump combines two good, but, alas, imperfect systems that I mentioned earlier. As a result, it turned out to be almost an ideal, which, I really hope, will become more and more accessible over time.

Firstly, this is a 2 in 1 option: central heating + hot water supply.

Secondly, although it is expensive, it is already within reach and may well compete with conventional boilers, if not at the cost of acquisition, then certainly at the cost of operation, definitely.

Thirdly, it is an air-to-water heat pump, which makes installation as accessible as when connecting a conventional boiler. No earthworks! I hung a panel on the wall (roof) and that’s it.

BUT now more.

The whole system consists of three components:

one. solar panels (note — aluminum), they are installed outside the house (walls, roof),
2. compressor (a small unit, the size depends on the power), all important processes take place in it.

Operating principlethe same as in the heat pump, works according to the «refrigerator in reverse» scheme.

  • The system circulates a liquid with a boiling point of -300FROM.
  • Passing through the solar panel, it heats up even from a temperature of -200FROM.
  • The compressor forces the heated liquid to move through the system and when it enters the aforementioned unit, it cools it with a condenser.
  • The released heat heats the water in the storage tank.
  • From the tank water with a temperature of about 55-650C enters the radiators (heating batteries), the kitchen, the shower, the pool.

IMPORTANT: based on the temperature data, it should be understood that along with the replacement of the boiler, it will be desirable to change the radiators to more efficient ones. They also work on water, however, the nominal temperature of the coolant (water) is required for them by 200C is lower, and their heat transfer is higher.

And, of course, the house itself must be insulated — at this point in time this is the generally accepted norm.


They work in any temperature range typical for the climate of our country.

They capture solar energy, and when there is no sun, they draw heat from the air, rain, snow. At the same time, the outlet water temperature fluctuates between 55-650FROM.

Very light (8 kg), made of anodized aluminum with a flexible water-repellent coating, size 2000 x 80 x 2 cm.

Filled with coolant (boiling point -300C), therefore they do not overheat and do not freeze, do not require cleaning and maintenance, can be mounted on a wall, roof, installed in a garden with a mandatory slope in the range of 10-850.

Panels are mounted on special fasteners. When ordering, you should be aware that the panels can be right and left, depending on the side of the contact output.

The service life is oriented at 25 years.
COMPRESSOR for heating

The only energy-consuming device in this system. Its task is to make the coolant circulate inside a closed circuit and heat the coolant of the heating system.

There is a liquid in the solar panel (remember, its boiling point is -300C) gets very hot from the ambient temperature, transfers heat to the compressor, where it gives it to the water with its help and, cooled, again flows to “warm up” into the panel.

The compressor in its «pure form» is connected to a closed water circuit for heating the house.


A thermally insulated water tank is designed to accumulate «life-giving» moisture for its subsequent consumption in the kitchen, in the shower and even in the pool.

Comes in a mandatory kit with a compressor that is built inside. Essentially the same boiler, but with a «magic» ten.

COMPRESSOR WITH STORAGE TANK for hot water and heating

Represents the previous design, supplemented by a built-in coil for heating the coolant in the water heating circuit.


The most «budget system» ECO300 is designed for a house with an area of ​​100-150 m2. It consists of three panels and a compressor with power consumption of 2.73 kW/day.

It costs about 6500 euros (December 2017) with operating costs in the range of 85 kW / month. We divide this amount by the service life of 25 years, then it turns out that for the year 260 euros per year.

If you divide this amount only by 5 cold months, when the heating works at full capacity, you get 52 euros per month. But after all, in other periods the system will also heat water, so in fact your expenses will be distributed over a greater number of months and therefore will be even less.

There is only one thing left: to find these 6500 🙂 and for the next 25 years you only pay 85 kW/month.
