Electric heating of a house, office or apartment - some will call such an idea a waste of electricity and money, while others will be delighted with the convenience of use, safety and lack of exhaust emissions. It is worth remembering that the term electric heating can cover various solutions, not only an electric central heating boiler , but also electric floor or wall heating, heat pumps, storage heaters and others. In this article, we will look at (not only) the advantages of an electric heater.

Is an electric furnace worth it?
A modern electric furnace has many advantages and can be successfully used even in energy-efficient construction. It entails much lower investment costs than, for example, gas heating. This includes both the purchase of the device, as well as the installation of the heating system or the preparation of an appropriate boiler room, and then servicing the system. In addition, investors appreciate the ease of installation (practically anyone can do it), convenience of use and safety of use - the device does not pose a risk of fire, explosion or carbon monoxide poisoning.
An electric boiler for central heating will be a cost-effective solution, among others, in a medium-sized energy-efficient house. There is nothing to prevent it from working with a solid fuel boiler and a fireplace, which will reduce operating costs. The connection of an electric boiler with a controller ensures optimization and automation of the heating system, and consequently - fully efficient and economical heating of rooms. Technologies and components used by manufacturers of electric furnaces increase their service life. The devices include, among others, solid resistance wires, a thermal fuse, overcurrent protection and other solutions.
Despite the high electricity prices, an electric furnace can be a cost-effective choice, but only if:
- relatively low heat demand of the building/premises,
- proper planning of the entire heating installation,
- skillful operation of the system.
Thanks to the government program "Clean Air" and thermal modernization relief, you can get funding of up to PLN 13,000 for the purchase of a new electric furnace. Details can be found at: https://czystypowietrze.gov.pl/wez-dofinansowanie/na-co-i-ile .
When deciding on electric heating, it is worth considering investing in renewable energy sources, such as a heat pump.
How much electricity does an electric stove use?
The power consumption of an electric furnace is influenced by various factors, in particular:
- type and power of electric boiler,
- the effectiveness of the thermal insulation of the building,
- applied solutions that automate and optimize the operation of the device,
using the boiler to heat domestic water.
It is worth knowing that modern electric furnaces for central heating are characterized by efficiency of up to 99.9%, which means that in practice 1 kWh of consumed electricity is converted into 1 kW of heat. It is estimated that the average annual heat demand of an average-sized energy-efficient building (i.e. with a usable area of 150 m2) is 6000 kWh. In the case of a standard house, this value can oscillate around 8000-13 000 kWh.
Electric Furnace Power Consumption and Electricity Bills
Electric heating costs, in addition to the factors listed in the previous paragraph, are also influenced by electricity tariffs. Bills for heating with electricity in a modern, energy-efficient single-family house with an area of 120 m2 and for heating water, using an appropriately selected tariff, do not have to exceed PLN 3,000 per year!
To find out the approximate costs of electric home heating, we recommend using free calculators available on the Internet. In order to reduce electricity bills to a minimum, it is worth combining an electric furnace with a photovoltaic installation. Energy produced from the sun allows you to reduce heating costs to... PLN 0.
