What type of heating should you look for when renting an apartment in Batumi for winter?

For a long winter stay, prioritize an apartment with gas, an individual boiler, and water radiators or underfloor heating; this is considered the most complete heating setup.

Before renting, confirm that the building is connected to the gas network: an in-apartment gas boiler is useful only where gas service is available.

In rental listings, “karma” refers to a wall-mounted gas convector, not a device that runs independently of gas. If an apartment has one, check its gas connection and operating arrangements.

Where an apartment already has a gas boiler, standard water radiators may be a clearer alternative to a gas convector because they use the boiler-based heating system.
