The total number of households connected to district heating has been moderately yet steadily growing over past five years. However, also disconnections are observed in several areas with higher heat prices. 1.6 million households are connected to district heating which represents approximately 40% of all households in the Czech Republic. The heating networks reach a length of about 10 thousand kilometres.
Primary energy consumption for district heating has been decreasing in the Czech Republic over the past decade, caused by energy savings and efficiency improvements. Fuel mix was also changing, as liquid fuels decreased while the share of renewable fuels has been increasing steadily. Furthermore, 80% of district heat is supplied through recycled heat. With regards to the fuel mix of heat produced by CHP, the dominant fuel is brown coal, which makes up more than 50% of the fuel consumption.
The graph displays that more than 40% of the Czech Republic’s residential heat demand is met through district heating. The main competitor in the heating market is the direct use of natural gas (natural gas boilers) and heat pumps. District heating and natural gas have currently comparable market share and together comprise over three quarters of the heat market in terms of number of households served.
There is no separate heat strategy document in the Czech Republic. However, the strategic goals for heating are included in the key documents from the energy sector. One of the strategic goals according to the State Energy Policy is to cover at least 20% of thermal energy needs from district heating by production from renewable energy sources and 60% by production from CHP by 2040.
