Summary for: Summer hot water shutdowns in Czechia: What to expect and how to copeEvery summer, Prague's most predictable inconvenience arrives right on schedule: the hot water disappears. Not because something has broken, and not because anyone forgot to pay the bill. It's planned, it's legal, and it happens to a large share of apartment buildings across the country at roughly the same time every year.
Heat suppliers are required to inform customers of planned interruptions in advance. In practice, this information is usually posted in building entrances or shared by property managers.
Here's what's actually going on, how to find out when it's your turn, and what to do about it.
Why does this happen?
Most apartment buildings in Czech cities are connected to centralized district heating networks (soustava zásobování teplem) rather than having individual boilers. These networks run continuously through the heating season, which means the only window for essential maintenance, pipeline inspections, and equipment overhauls is the summer.
Energy suppliers are legally entitled to schedule these shutdowns, and building managers are legally required to post advance notice on the entrance door. In practice, the notice sometimes goes up with very little lead time, so it pays to check proactively.
Outages typically last between three and seven days, although some scheduled maintenance lasts a week or longer. The timing varies significantly by district, street, and even individual building, your neighbor two doors down may have hot water when you don't.
How do people shower?
- Take advantage of the weather. In July and August, tap water is much warmer than it is in winter, making a cold shower far more bearable.
- Heat water only for what you need. Boiling a kettle or two and mixing it with cold water in a basin is usually enough for washing your hair or taking a sponge bath for a few days.
- Use the gym or swimming pool. Many people time a workout with a shower at their local gym. If you have a MultiSport or Benefit Plus card, this can be the easiest solution. Prague's outdoor swimming pools and lidos also have showers and changing facilities, making them a popular option during outage season.
- Plan ahead. If you know your shutdown dates, wash your hair, do dishes that need soaking, or tackle other hot-water-heavy chores before the outage begins.
- If you're working from the office, shower there. Many larger employers provide shower facilities for cyclists or runners, and some people simply take advantage of them during maintenance week.
- Check with your neighbors. Because shutdown schedules vary from street to street, and sometimes even between neighbouring buildings, you may have a friend or colleague nearby whose building still has hot water.
Why doesn't everyone just have a boiler?
Most apartment blocks built during the socialist era were designed to use district heating supplied from central plants. Replacing those systems with individual boilers would require major reconstruction and is usually neither practical nor economical.
How do you find out when your shutdown is?
This depends on who supplies your heat.
In Prague, the main supplier is Pražská teplárenská (PTAS), which covers the majority of the city's district-heated buildings. Their outage map lets you search by address and view planned shutdown dates. You can also check here. Your district's hompage or social networks should also provide notices.
In Prague, outages often cluster around early July and late August. According to PTAS published schedules, major disruptions this year include large parts of Prague 8 (Bohnice, Kobylisy) and Prague 9 (Prosek, Střížkov) from July 4–11, while Prague 4 residents in Podolí and Zelený pruh face shutdowns from June 26 to July 2 and again from Aug. 24–29, with Krč and the Novodvorská area affected from Aug. 17–20.
Outside Prague, ČEZ operates a live outage tracker at udalosti.vecr.cz covering towns and regions across the country. Veolia, United Energy, and other regional suppliers also publish schedules on their own websites; if you're unsure who your supplier is, your building manager or the notice on your front door should have that information.
One thing that could save you money
One practical tip during a scheduled hot water shutdown: don't automatically leave your mixer tap set to the hot-water side.
United Energy, one of Czechia's district heating suppliers, advises residents that, depending on how a building's plumbing is configured, drawing water through the hot-water circuit during a planned outage may still register as hot water consumption, even though the water isn't being heated.
The exact setup varies from building to building, but the simplest way to avoid any unnecessary charges is to switch taps to the cold setting for the duration of the shutdown.
What you cannot do (and what to watch for)
For renters, one important distinction is worth understanding: a scheduled summer shutdown is not the same as a fault or breakdown.
Planned maintenance of district heating systems is legal and expected. But if hot water is missing outside of the announced dates, or if your building has its own boiler system that fails unexpectedly, that is no longer a planned outage. In those cases, the landlord or building manager is generally responsible for arranging a repair within a reasonable timeframe under the terms of the lease.
If something seems wrong, the first step is simple: check the posted notice in your building and contact your building manager (správce) to confirm whether the outage is planned or not.
When in doubt, assume nothing and check the dates: hot water in Czech apartment blocks is almost always predictable, even if it doesn’t feel like it at first.
