In short
Houses in Georgia are most often heated with a gas boiler and radiators or underfloor heating: where gas is connected, this is the most economical option, because gas here is usually cheaper than electricity. Air conditioners are handy in the shoulder seasons, a heat pump saves money long term but costs more upfront, and electric underfloor heating is expensive as the only heat source. The boiler is sized from heat losses, and without an insulated facade and roof any system heats the street.
Winter in Tbilisi can hit −5 °C, and it is noticeably colder in mountain areas. Heating is chosen back at the design stage: the routing, the electrics and even the thickness of the screed depend on it. Let us compare the main options for Georgia.
The main systems
- A gas boiler + radiators or underfloor heating: the most common and economical option where gas is available.
- Electric underfloor heating: comfortable in bathrooms and kitchens, but expensive as the sole heat source.
- Air conditioners (inverter in heating mode): a quick start, handy in the shoulder seasons, tied to the price of electricity.
- A heat pump: high efficiency and long-term savings, but more expensive upfront.
What to weigh when choosing
Look not at the price of the equipment but at the cost of a heating season. Gas in Georgia is usually cheaper than electricity, so a boiler with underfloor heating wins over time. But insulation decides everything: in a house without an insulated facade and roof any system will heat the street. Underfloor heating needs a proper screed and is laid before the finish.
How not to overpay
The boiler power and the number of circuits are calculated from the house’s heat losses, not by eye: an oversized system costs more and works worse. Design the heating together with the engineering from the start. We carry out heating and underfloor heating installation to the design, with pressure-testing and a warranty on the hidden works, and we design the system in from the start on turnkey house construction in Tbilisi. On the other half of the problem, see Facade insulation.
