Your personal savings directly depends on which electricity tariff you have!

If your tariff is normal, for example UAH 2.64 for 1 kWh of electricity, then your savings will be approximately 40% of gas heating. Remember, 400 kWh must be used to obtain 1 gigacalorie of heat, which is UAH 1,056. Heating with gas will require 143 cubic meters of gas to produce 1 gigacalorie. Calculate the difference yourself!

If you set up 2-zone accounting (it’s easy and inexpensive, ask your inspector or call the energy distribution company), then your integral daily tariff will decrease by 15% and will be UAH 2.2 per 1 kWh of electricity. Accordingly, the cost of obtaining 1 Gcal will decrease by 15% and will amount to UAH 880. Calculate the difference between UAH 880 and UAH 1,487 yourself.

Savings compared to wood or pellet boilers are calculated using the same method. But most people who have ever used wood or pellet boilers switch to heating with a heat pump not because of the difference in the cost of heating, but because:
– no need to regularly clean chimneys!
– no need to haul, chop firewood
– there is no stench of smoke
– there is no danger of fire!

– there is no danger of fire!

Heating with a heat pump Prometheus – water. This means that we heat the heating water in our conventional heating system that you already have. Possible options, namely:

2.1. If you had an “open” heating system (with an expansion tank in the attic of the building), then you will have to convert it to a “closed” one! The reason is that the water pressure in the system, where the heat pump must work, is higher than in the “open” one, and the volume of water is driven through the radiators more. Therefore, it is necessary to shut off the open expansion tank in the attic and install a membrane tank in the boiler house, below.

In addition, it will almost certainly be necessary to replace the circulation pump in the boiler room with a pump with a higher capacity – with an operating point of at least 2.5 m3/h. This is necessary so that you can completely “remove” the heat that the heat pump can produce! With a small flow of liquid (heating water), you need a higher water temperature, but the heat pump cannot heat the heating water above 58 C. So you need to increase the amount of water, that’s clear!

2.2. If you want to use your heat pump and gas (electric) boiler alternately, and do not plan to use them simultaneously in automatic mode, then we simply “cut” the supply and return pipelines of the heat pump into your supply and return pipes, of course with cut-offs cranes (3-way with manual drive).

2.3. If you plan to use your gas boiler and heat pump together, in automatic mode, then the connection scheme must be different.

2.3.1. With a hydraulic distributor (Hydrostrelka), similar to a single-circuit boiler.

2.3.1. With the use of a buffer tank into which all heating devices (gas, electric, wood-burning boilers) are connected.

Automatic operation of all heating units in your house requires high installation costs, but it will ensure automatic and optimal use of all heat generators for comfortable heating.

The conditions for providing a 2-year warranty require the installation of special devices in the power supply line of the heat pump.

3.1. Voltage control relay – RKN, which turns off your heat pump automatically in the event of a voltage surge. RKN works together with a contactor and a protective disconnection device. The fact is that refrigeration equipment, and the heat pump belongs to the class of refrigerating units, includes compressors driven by electric motors. Expensive equipment should be disconnected from the network if the voltage deviation exceeds 8% of the nominal value. After enduring a pause (set to RKN) of 3 minutes, or 180 seconds, your heat pump will start working again automatically!

Stabilizers are good, of course, but they don’t have time to “work off” voltage surges, so installation of RKN is mandatory!

3.2. Inside the heat pump itself, there are several automatic protective devices, namely – against high pressure in the freon line, protection against high current in the compressor circuit, etc. But with the joint operation of a heat pump and a wood-burning boiler, for example, we will recommend installing a freon overheating protection circuit when switching from a high-temperature heat generator (solid fuel or gas boiler) to a low-temperature one (heat pump)!

If we try to explain briefly, if there is a sudden supply of water with a temperature above 55 ° C to the input of the heat pump, heating of the Freon gas in the Freon-water heat exchanger and its rapid expansion will occur. The gas pressure in the freon line increases and there have been cases of its destruction. To avoid incorrect use of the heat pump when used together with other heat generators, we will strongly recommend installing an overheating protection circuit.

An alternative connection for joint work – using a buffer capacity, does not save you from using the overheating protection circuit!

It is possible to heat water with a heat pump, and we recommend doing it based on economic considerations!

The cost of 1 gigacalorie obtained by the Prometheus heat pump is lower than the cost of 1 gigacalorie obtained by your electric boiler by 4.5 times in summer and 2.9 times in winter, remember?

To obtain hot water, you will need an indirect heating boiler (a tank with a coil inside). There are buffer tanks of the combined type, where such a boiler is integrated into the structure of the buffer tank. This saves some space in the boiler room. Our engineers have details of receiving the DHW.

The main difference between monobloc heat pumps and the split type is that the circuit of your heating water “goes out” to the street, that is, the pipe in which the water of your heating system flows must be connected to the unit that is in the open air!

There is nothing wrong with this, except in cases of power outage for more than 2 hours. If the water in the freon / water heat exchanger has stopped due to the lack of power supply to the heat pump and the circulation pump, then there is a risk of freezing of this water in the heat exchanger on the street and rupture of this precious node with ice (defrosting). In the event of a power outage, you need to go outside and drain the water from the outdoor unit of the heat pump to avoid very serious damage to the unit.

Heat pump split type – Prometheus does not have elements with water on the street. The Prometheus heat pump consists of 2 units – external and internal, which are connected by copper pipes (freon pipes), like a split air conditioner. The freon/water heat exchanger is located inside the building, in the hydraulic module, and therefore such a system is not afraid of a house power cut.

In addition to the above-described drawback, there is another drawback of monoblock heat pumps when used in our latitudes, which is not obvious even to specialists. This is an inevitable gradual destruction and deterioration of thermal insulation of water elements that are in the air, on the street. The heat exchanger itself is wrapped in thermal insulation based on synthetic foam rubber and pipelines that fit to and from it. But over time, the insulation breaks down (you yourself have probably seen how quickly the black pipes that connect the units of your air conditioner crack). This leads to heat loss already at the output of the heat pump, a decrease in its efficiency, and to complex work on disassembling the unit and restoring the insulation.
Many years of experience using heat pumps in Canada prompted us to make a choice in favor of split systems connected by a freon pipeline.

Air conditioning with a Prometheus heat pump is possible! For this, the heating system of your house (apartment) must have special radiators with fans – fan coils.

There are different types of fan coils – wall, ceiling and others, but all of them are quite expensive devices, which are usually provided for during the construction or repair of your house in advance!

It is not possible to air-condition with the help of ordinary batteries – radiators (there is no convection).

In addition to the above, you need to remember that in the design of Prometheus heat pumps there is only one freon / water heat exchanger and you will have to choose what to use in the summer – air conditioning (if there are fan coils) or hot water.

There are heat pumps that “know” how to heat hot water at the same time as air conditioning, they are more expensive and are called – with heat recovery. Given the small demand, our organization does not import cars of this class until now!

The warranty is valid for 2 years from the moment of sale of the heat pump to you. In order to issue a warranty card to you, the following conditions must be met:

8.1. The correctness of the installation and the presence of protection systems must be confirmed by our warranty engineer.

8.2. In the power supply circuit, the presence of protective automation (RCN, contactor of the automatic switch) is mandatory

8.3. In the heating water circuit, when working together with a high-temperature heat source such as a solid fuel boiler, gas boiler or any other device, there must be a protective circuit against overheating, which includes a 3-way valve with an electric drive, a thermostat controlling this valve.

8.4. Follow all the rules for transportation and operation described in the user manual.

8.5. If, during the external inspection of the heat pump, traces of intervention by outsiders in the construction of the unit are visible, the warranty will be voided.

In addition, the warranty is terminated upon re-installation of the unit that worked at another facility.

Absolutely! If your multi-apartment building is a condominium or residential complex, you have the right to compensation for the costs of heat pump heating and hot water in the total amount – 80% from various budgets (details from the specialists of the operating banks Ukrgasbank, Privatbank, etc.)

A heating system is considered bivalent if it has two or more heat generators in its composition, capable of working simultaneously. It can be a heat pump and a solid-fuel boiler, a heat pump and an electric boiler, a solid-fuel and gas boiler, and even a city heat network and a heat pump together!

Savings from the use of heat pump heating in condominiums, condominiums depends on what electricity tariff your house has, and what you use as a heat source at the moment!

For example, if your condominium received heat from the heating network, then you bought it at UAH 1,539 per 1 gigacalorie in Kharkiv in the 2021-2022 season.

If at the same time, your electricity tariff is UAH 1.68 as for residential buildings, then the production of 1 gigacalorie using a heat pump for your condominium will cost in winter

400 kWh * 2.64 UAH = 1056 UAH.
Benefit – 31%!

If your condominium, housing complex will still heat hot water with the help of a heat pump installation, then the benefit will consist of 2 parts – winter and summer. In the summer, the heat pump unit produces hot water and uses approximately 260 kWh of electricity or 260 kWh * UAH 2.64 = UAH 686.

The benefit in summer is 54%! In fact, a bivalent heating system will be built in your condominium, residential complex, which will mainly use the heat from the heat pump and take some heat from the heating network.

There is a benefit, and it is calculated as the difference between the cost of 1 gigacalorie obtained by a gas boiler at the tariff set for your particular house and the cost of 1 gigacalorie obtained with a Prometheus heat pump.

If your gas tariff is 8.00 + 2.40 UAH per 1 cubic meter, then the cost of 1 gigacalorie will be 1487 UAH. The cost of 1 gigacalorie from thermal Prometheus depends on the electricity tariff and will be UAH 1,056 in winter and UAH 686 in summer! Benefit in winter 30% and 54% in summer (for GWP)!

Remember that condominiums and condominiums have the right to compensation of about 80% of the cost of equipment, use it, don’t waste a moment while the compensation program is working!

Yes, you can! Electric boilers can be used as a second (reserve) source of heat. The share of heat produced during the season by an electric boiler, as a rule, does not exceed 10% for the latitude of Kharkiv.

Most likely, in order to build a completely independent heating system, the board of condominiums, housing complexes will have to “buy additional” installed capacity from regional energy (electricity supplier), but it is still more profitable than paying heat networks!

In addition, it gives your condominium or condominium the following opportunities:

14.1. Manage heating regardless of the start of the official heating season! People often get sick at a time when the houses are already damp and cold, and the heating season has not yet started.

14.2. Forget about turning off hot water in the summer!

14.3. Automatic energy-efficient weather-dependent regulation of water temperature in radiators, which leads to additional financial savings, even without the purchase and use of ITP (there is simply no need for it).

14.4. For buildings located in remote areas of the heat network, the problem of low temperature of the heat carrier is solved due to increased heat extraction by buildings located earlier along the highway.
And other.
