Pursuant to the Regulation of the Minister of Transport, Construction and Maritime Economy of July 5, 2013, amending the regulation on the technical conditions to be met by buildings and their location, from January 2021, the demand of a new single-family building for non-renewable primary energy (EP) does not may exceed 70 kWh/m2 per year. Modern house insulation technologies and the growing popularity of energy-efficient construction mean that the demand for heat is decreasing and the operating costs of most types of heating are decreasing. Therefore, heating systems with low investment costs are particularly attractive to investors . Here we will look at electric heating, the investment costs of which are the lowest compared to other heating systems of comparable quality.
Conventional wisdom regarding electricity may make the costs of electric heating seem to be the highest. However, when choosing a heating system, you should also take into account the investment costs associated with purchasing a boiler or heat pump and connections. Additionally, it is necessary to include the replacement of equipment after a period of 15-20 years, which makes electric heating an attractive solution both in the short and long term. DEVI heating cables have an extended 20-year warranty, and when professionally installed, they can last for over 50 years.

By using electric heating you can pay low bills. The condition is that the system is tailored to individual needs. Moreover, electricity is the only source of heat that costs much less at night. In central systems, heat is generated in the boiler room and distributed throughout the house via pipes. To heat one selected room, it is necessary to heat the entire medium flowing through the entire system. Additionally, heat distribution pipes are not insulated, which causes heat loss. This problem does not exist with electric heating. This is a system with the lowest energy losses.

An economical way to use electricity in underfloor heating is to use cheaper electricity in the second tariff period and use the accumulated heat in the remaining periods. Additionally, generating electricity from sunlight is becoming more and more popular.
The cost of 1 kWp of a photovoltaic installation is approximately PLN 4,000-6,000. zloty. From 1 kWp of a photovoltaic installation per year in Poland, we are able to produce on average 1,000 kWh of electricity. Of course, we produce the most in the summer, when we need it the least. Fortunately, the PROSUMENT program is in force in Poland, which assumes that for installations up to 10 kWp, we can collect 80% of the energy we put into the grid within a year. In the case of installations larger than 10 kWp, we can collect 70% of the supplied electricity. In this way, we produce electricity in the summer, which we will use in the winter to power heating cables. Thanks to this , we can reduce the operating costs of the house to even zero.

- PROSUMENT program (80% of the energy fed into the grid can be used within a year)
- Zero energy house thanks to the use of heating cables and photovoltaics
Annual heating costs using heating cables and a photovoltaic installation*
| Heating cables | Cables + photovoltaics 3 kWp | Cables + photovoltaics 9 kWp | Cables + photovoltaics 12 kWp | |
| Installation cost (PLN) | 14,255 | 28,655 | 52,055 | 62,255 |
| Operating cost (PLN) | 2,502 | 1,870 | 607 | 292 |
* We assume that all energy generated from the photovoltaic installation is fed into the grid and collected in accordance with the Prosument program - 90% or 70% for installations above 10 kWp.
