Some Prague homes to have no hot water

Planned maintenance will cause shutdowns to the city's heating network

Some households in Prague will go without hot water temporarily. A large number of buildings get hot water from central heating plants, and some of the pipelines and plants will be undergoing planned maintenance. The work is being done in the summer when many people will be on vacation so that the impact will be minimized.

“Previously, the northern and southern parts of Prague were shut down. Now only parts of substations are now being shut down. Three-week shutdowns used to be common, but today they are significantly shorter,” Milan Trojan, the head of the investment and maintenance department of heating company Pražská teplárenská, said in a press release.

People who will be affected should already have been informed.

“I would like to remind people that the purpose of the shutdowns is not to bother customers or to ensure a quiet holiday for our employees but to prepare the heating system for the next heating season as best as possible and to prevent unpleasant disturbances in the winter season,” he added.

Pražská teplárenská's 550-kilometer-long network supplies 225,000 households, dozens of schools, hospitals, offices, administrative buildings and industrial buildings across the city.

Maintenance must be planned so it can be be as short as possible. “It's not always possible, but we're trying to keep the shutdowns to no more than seven days. At the same time, it should reach a maximum of one weekend and also take into account public holidays. For example, in Michle, the shutdown will start on June 29 and will end on July 4, so the local people can rely on warm water during the holidays [on July 5 and 6],” he said.

Most shutdowns are centered around the planned work at the thermal power plant of the Mělník Power Station on July 10–16. The Mělník plant will be out of service these days due to regular maintenance. Except for days when temperatures fall below zero and need to be augmented, the Mělník plant is the main source of hot water for Prague Heating Systems (PTS). The largest hot-water pipeline in Central Europe, with a diameter of 1.2 meters, flows to Prague in winter with up to 650 MW of heat.

Inhabitants of Černý Most will have longer outages, from July 10 to 23. “This is an extensive and technologically demanding project where several hundred meters of primary heat management will be repaired. To supply such a large site as Cerny Most, unfortunately, spare resources are not possible. Of course, we informed the local residents in advance so they had enough time to prepare for the shutdown,” Trojan said.

A similar situation is expected by the inhabitants of Třtinová Street in Čakovice, where the hot water will be shut down in the second half of August.

Work concerning the upper part of Holešovice started already in May affecting the area between the streets of Dukelských hrdinů and Bubenská. There will be a technological transformation to reduce the losses due to obsolete construction.

Some areas of Prague will not experience any outages due to mobile equipment replacing the hot water supply.

“Even before this year's repairs are over, we are starting to plan downtime for 2019 because the maintenance of the Prague Heating System is an endless process,” Trojan said.
