FAQ
TL;DR: For ~50 m² flats, coal feeding many district systems rose 3–4×; "Nobody knows what it will be like tomorrow." Choose district heat for convenience or an individual gas boiler for control and pay‑per‑use. [Elektroda, zdzichra, post #20339021]
Why it matters: If you’re buying a ~50 m² flat, this FAQ answers “gas or city heat?” with clear guidance on costs, control, and pitfalls.
Quick Facts
- Historically, district heat was more convenient and slightly cheaper than gas, but prices are volatile. [Elektroda, zdzichra, post #20338991]
- In blocks, a manager often sets heating on/off; turning radiators off doesn’t avoid a fixed share. [Elektroda, zdzichra, post #20338991]
- Typical trigger: about 3 days below 10°C; networks still heat hot water in warmer months. [Elektroda, stachu_l, post #20339134]
- Individual gas boilers give anytime control; shared gas boiler rooms work like central systems. [Elektroda, stachu_l, post #20339389]
- Gas boiler replacement can cost several thousand; include lifecycle cost, not just fuel. [Elektroda, 78db78, post #20339014]
Which is cheaper for a 50 m² flat: district heating or gas?
There’s no fixed winner because tariffs change. “So far, municipal heating has been more convenient and slightly cheaper than gas heating.” Gas gives independence and flexible timing, but you own maintenance risk. Compare current heat tariffs, gas prices, metering, and building rules before deciding. Align choice with your control needs and risk tolerance. [Elektroda, zdzichra, post #20338991]
Can I heat whenever I want with district heating?
Usually not. In blocks or tenements, the manager sets start and stop dates. A typical criterion is roughly three days below 10°C before switching on. If your flat has an individual heat meter, you can close radiators, but building rules still apply. Expect domestic hot water to run year‑round via the network. Ask the manager about exact policies and metering. [Elektroda, stachu_l, post #20339134]
Do shared gas boiler rooms give me the same control as an individual gas boiler?
No. A shared gas boiler room behaves like any central system, with building‑level scheduling. An individual apartment boiler lets you heat anytime and tailor indoor temperatures. When reading listings, verify whether “gas heating” means your own boiler or a shared one. Ask for system type and metering details up front to avoid surprises. [Elektroda, stachu_l, post #20339389]
What hidden costs should I expect with a gas boiler?
Plan for replacement if it fails. A broken or unrepairable unit can cost several thousand to replace. Budget for inspections and maintenance, too. Consider total cost of ownership over 10–15 years, not just monthly fuel. Ask the seller for service records and boiler age before committing. [Elektroda, 78db78, post #20339014]
Is boiler oversizing a problem in 45–50 m² flats?
Yes. Small flats often face limited boiler size options, which can mean an overpowered unit. Oversizing can force the boiler to run almost constantly and cycle inefficiently. Check the model’s minimum modulation and suitability for small loads. Ask for documentation and observe cycling behavior during a viewing. [Elektroda, 78db78, post #20339407]
Is district heating actually cheaper than gas today?
It can be, especially when supplied from coal‑fired CHP. “Municipal heating… should be significantly cheaper.” The trade‑off is control: you may get heating even on warm days. Verify current tariff tables and your building’s billing method. Prices can shift quickly with fuel markets and seasonality. [Elektroda, Zbigniew Rusek, #20339116]
Will I pay for heating if I turn my radiators off?
It depends on metering and settlement. With an individual heat meter, you can close radiators and pay for what you use. Older riser systems may use radiator dividers or even area‑based settlement, which charge shared costs. Ask how your building bills heat and whether meters are installed. [Elektroda, stachu_l, post #20339134]
Should I avoid radiator heat dividers?
Yes. Prefer flats with apartment‑level heat meters. Heat meters settle actual consumption more fairly than radiator dividers. Dividers can misrepresent heat use in riser‑based systems. Confirm the metering method with the seller or manager before purchase. [Elektroda, slider2002, post #20349365]
Can I switch from a shared system to an individual gas boiler later?
It depends on the building’s layout and how many rooms the shared system feeds. Speak with neighbors and the manager about feasibility and rules. Conversions may be complex, so get clear answers on technical and administrative constraints first. [Elektroda, zdzichra, post #20342067]
How do I check if an advertised “gas heating” flat has an individual boiler?
- Ask the agent whether the gas boiler is exclusive to the apartment or shared.
- Request photos of the boiler and its location inside the flat.
- Confirm metering: individual gas meter and DHW heating vs building‑level plant.

Do district‑heated buildings supply hot water year‑round?
Typically yes. Heating networks usually run all year, delivering domestic hot water during warm months. Central heating then activates based on building policy or temperature criteria. Ask which services your substation provides and how DHW is billed. [Elektroda, stachu_l, post #20339134]
What happens if the district network fails or the station pump stops?
With an individual gas boiler, you keep heating regardless of district outages. Network failures or substation pump issues affect central supply, not your in‑flat boiler. If uptime matters, individual gas offers resilience at the cost of ownership. Keep boiler maintenance current to preserve that resilience. [Elektroda, zdzichra, post #20338991]
Could substation leaks inflate my bill?
Yes, leaks on the central side can increase shared consumption. With your own gas boiler, you pay for what you use in the flat. Ask the manager about leak monitoring and recent repairs in district‑heated buildings. Review settlement rules to understand exposure to shared losses. [Elektroda, zdzichra, post #20339390]
