Before every winter, the same question comes up: what&#8217;s better \u2014 a gas boiler, an electric heater or an inverter air conditioner? In this article we compare which heating is the cheapest in Georgia using 2026 tariffs.<\/p>\n<div class=\"dv-info\"><strong>Short answer:<\/strong> for an 80 m\u00b2 apartment, the heating cost for one season is roughly: <strong>gas boiler \u2014 450\u2013500 GEL<\/strong>, <strong>inverter air conditioner \u2014 600\u2013700 GEL<\/strong>, <strong>electric heaters \u2014 up to 2,000 GEL<\/strong>. Gas is still the cheapest option.<\/div>\n<h2>Gas and electricity tariffs in Georgia in 2026<\/h2>\n<p>From 1 April 2026, the household electricity tariff in Tbilisi increased.

Below is the cost of one season (November to March) for an 80 m\u00b2 apartment in Tbilisi with average insulation, at 2026 tariffs.<\/p>\n<figure class=\"dv-fig\" style=\"margin:26px 0 30px\"><img loading=\"lazy\" src=\"https:\/\/datvale.ge\/wp-content\/uploads\/2026\/10\/heating-cost-georgia-season-80m2.webp\" alt=\"Heating cost in Georgia per season: gas vs inverter vs electricity for an 80 m\u00b2 apartment\" width=\"1200\" height=\"750\" loading=\"lazy\" decoding=\"async\" style=\"display:block;width:100%;height:auto;border-radius:16px;border:1px solid #dce7f2\"><\/figure>\n<p>As you can see, the heating cost with electric convectors is about four times higher than with a gas boiler. That difference is up to 1,500 GEL in one season and over 7,000 GEL in five years, almost as much as installing a complete gas system.<\/p>\n<h2>Heating cost by apartment size<\/h2>\n<p>Many readers want to know what the heating cost will be in a smaller or larger apartment. Here are indicative figures for three typical sizes under the same conditions: average insulation, a middle floor and a room temperature of about 21\u201322\u00b0C.<\/p>\n<figure class=\"dv-fig\" style=\"margin:26px 0 30px\"><img loading=\"lazy\" src=\"https:\/\/datvale.ge\/wp-content\/uploads\/2026\/10\/heating-cost-by-apartment-size.webp\" alt=\"Heating cost by apartment size in Georgia: 50, 80 and 120 m\u00b2\" width=\"1200\" height=\"750\" loading=\"lazy\" decoding=\"async\" style=\"display:block;width:100%;height:auto;border-radius:16px;border:1px solid #dce7f2\"><\/figure>\n<p>Keep in mind these are averages. On the top or ground floor, in a corner apartment or with poor windows, the heating cost can be 20\u201340% higher. In a well-insulated new building, it can be 15\u201325% lower.<\/p>\n<h2>Heating cost over 5 and 10 years: installation plus usage<\/h2>\n<p>When choosing a heating system, people often compare only installation prices. That is a mistake: a system runs for 10\u201315 years, and the main expense is yearly consumption. Let&#8217;s calculate the total cost for an 80 m\u00b2 apartment using average figures:<\/p>\n<div class=\"dv-table-wrap\">\n<table>\n<thead>\n<tr>\n<th>System<\/th>\n<th>Installation<\/th>\n<th>5-year total<\/th>\n<th>10-year total<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Gas boiler + radiators<\/td>\n<td>\u2248 6,000 GEL<\/td>\n<td>\u2248 8,400 GEL<\/td>\n<td>\u2248 10,750 GEL<\/td>\n<\/tr>\n<tr>\n<td>3 inverter air conditioners<\/td>\n<td>\u2248 4,000 GEL<\/td>\n<td>\u2248 7,250 GEL<\/td>\n<td>\u2248 10,500 GEL<\/td>\n<\/tr>\n<tr>\n<td>Electric convectors<\/td>\n<td>\u2248 1,400 GEL<\/td>\n<td>\u2248 11,400 GEL<\/td>\n<td>\u2248 21,400 GEL<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>An interesting result: in total, an inverter air conditioner comes out at almost the same price as a gas boiler, especially in the first years, and it also cools in summer. However, a gas system gives more comfortable, even heat, also makes hot water and works reliably in hard frost. Electric convectors are clearly the most expensive option in the long run.<\/p>\n<h2>What raises your heating cost: 6 main factors<\/h2>\n<h3>1. Insulation<\/h3>\n<p>Wall, ceiling and floor insulation has the biggest impact. In an old building without insulation, an apartment of the same size can need twice as much heat as in a modern, well-insulated building.<\/p>\n<h3>2. Windows<\/h3>\n<p>Old wooden or single-glazed windows lose 20\u201330% of the heat. Modern double glazing and a good seal reduce the heating cost considerably.<\/p>\n<h3>3. Floor and position<\/h3>\n<p>On the top floor, heat escapes through the ceiling; on the ground floor, through the floor. A corner apartment has two or three external walls, and north-facing rooms get almost no sun. All of these raise the heating cost.<\/p>\n<h3>4. Ceiling height<\/h3>\n<p>An apartment with 3.2 m ceilings needs about 15\u201320% more heat than one with 2.7 m ceilings, because there is more air to heat.<\/p>\n<h3>5. Room temperature<\/h3>\n<p>As a rule of thumb, every extra degree of room temperature increases the heating cost by about 5\u20136%. Choosing 21\u00b0C instead of 24\u00b0C can save up to 15% per season.<\/p>\n<h3>6. System condition<\/h3>\n<p>A boiler that has not been serviced for years, dirty radiators or air in the system reduce efficiency by 10\u201315%. Annual servicing usually costs 80\u2013150 GEL and pays for itself in the first season.<\/p>\n<h2>How to calculate the heating cost of your own apartment<\/h2>\n<p>General figures are a good guide, but you can calculate your own heating cost in a few minutes. You need three things: the floor area, the approximate heat demand and the price of energy.<\/p>\n<ol>\n<li><strong>Heat demand.<\/strong> An apartment with average insulation in Tbilisi needs roughly 85\u201395 kWh of heat per m\u00b2 per season. A well-insulated one needs 65\u201375, a poorly insulated one 110\u2013130.<\/li>\n<li><strong>Multiply by the area.<\/strong> For example, 70 m\u00b2 \u00d7 90 kWh = 6,300 kWh per season.<\/li>\n<li><strong>Multiply by the price of 1 kWh of heat.<\/strong> About 0.065 GEL with gas, 0.095 GEL with an inverter and 0.285 GEL with an electric heater.<\/li>\n<\/ol>\n<p>For a 70 m\u00b2 apartment, that comes to about 410 GEL with gas, 600 GEL with an inverter and 1,800 GEL with electric heaters per season. This simple formula lets you know your heating cost before choosing a system and compare it with the installation price.<\/p>\n<h2>8 ways to cut your heating cost by 20\u201330%<\/h2>\n<figure class=\"dv-fig\" style=\"margin:26px 0 30px\"><img loading=\"lazy\" src=\"https:\/\/datvale.ge\/wp-content\/uploads\/2026\/10\/heating-cost-8-ways-to-save.webp\" alt=\"8 ways to cut your heating cost\" width=\"1200\" height=\"750\" loading=\"lazy\" decoding=\"async\" style=\"display:block;width:100%;height:auto;border-radius:16px;border:1px solid #dce7f2\"><\/figure>\n<ol>\n<li><strong>Seal windows and doors.<\/strong> Replacing and adjusting window seals costs 20\u201340 GEL per window and stops drafts.<\/li>\n<li><strong>A programmable thermostat.<\/strong> A 100\u2013300 GEL device automatically lowers the temperature at night and when nobody is home.<\/li>\n<li><strong>Night mode.<\/strong> 18\u201319\u00b0C while sleeping is good for your health and lowers the bill.<\/li>\n<li><strong>Keep radiators clear.<\/strong> A thick curtain or sofa in front of a radiator &#8220;eats&#8221; a significant share of its heat.<\/li>\n<li><strong>Annual boiler servicing.<\/strong> A clean burner and correct pressure keep efficiency high.<\/li>\n<li><strong>Thermostatic radiator valves.<\/strong> They let you keep the bedroom cooler and the living room warmer.<\/li>\n<li><strong>A reflective screen.<\/strong> A foil layer behind a radiator on an external wall reflects heat back into the room.<\/li>\n<li><strong>Insulation.<\/strong> Insulating an external wall or the fa\u00e7ade is the most expensive step but the most effective, often saving 25\u201335%.<\/li>\n<\/ol>\n<h2>Which boiler: standard or condensing?<\/h2>\n<p>If you choose gas heating, the next question is the boiler type. A standard boiler converts about 90% of gas energy into heat, while a condensing boiler reaches up to 105\u2013108% (by lower heating value) because it also uses heat from exhaust vapor. In practice this means a 10\u201315% lower heating cost.<\/p>\n<p>A condensing boiler costs 800\u20131,500 GEL more, so it pays off best in a large apartment, a private house or with water underfloor heating, where water temperatures are low and the boiler works at maximum efficiency. In a 60\u201380 m\u00b2 apartment with radiators, a good standard boiler is also a perfectly sound choice.<\/p>\n<h3>Capacity<\/h3>\n<p>An oversized boiler cycles on and off too often, which lowers efficiency and increases wear. As a guide, allow 1 kW per 10 m\u00b2 with average insulation. For a combi boiler that also heats water, 24 kW is usually enough for an 80\u2013100 m\u00b2 apartment.<\/p>\n<h2>Hybrid heating: gas plus an inverter<\/h2>\n<p>Many families combine two systems. The gas boiler runs in the coldest months (December, January and February), while in autumn and spring, when it is 8\u201315\u00b0C outside, an inverter air conditioner heats individual rooms quickly and efficiently. In summer, the same unit is used for cooling. This combination can cut the seasonal heating cost by 10\u201320%, because you no longer need to run the whole system to heat one room in mild weather.<\/p>\n<h2>Inverter air conditioners in winter: what to look for<\/h2>\n<ul>\n<li><strong>Heating efficiency class (SCOP).<\/strong> Look for a high seasonal coefficient, A+ or A++ in heating mode. The higher the SCOP, the lower the heating cost.<\/li>\n<li><strong>Operating temperature.<\/strong> Good models heat reliably down to \u221215 or \u221220\u00b0C. The efficiency of cheap models drops sharply below 0\u00b0C.<\/li>\n<li><strong>Capacity for the room.<\/strong> For heating, the unit should be slightly more powerful than for cooling alone, for example 12,000 BTU rather than 9,000 for a 20 m\u00b2 room.<\/li>\n<li><strong>Outdoor unit position.<\/strong> A place sheltered from wind and a proper defrost system ensure stable winter operation.<\/li>\n<\/ul>\n<p>In Tbilisi&#8217;s climate, where most winter days are between 0 and 8\u00b0C, a good inverter works quite efficiently and its heating cost is only 30\u201340% higher than a gas boiler. In mountain regions with frequent hard frost, gas or solid fuel is the better choice.<\/p>\n<h2>Heating cost in a private house<\/h2>\n<p>In a private house, the heating cost is usually higher than in an apartment of the same size, because a house has external walls, a roof and a floor on every side and no neighbors&#8217; heat to help. A 120 m\u00b2 house with average insulation uses 900\u20131,300 GEL of gas per season, and a poorly insulated one 1,500 GEL or more. In a house, insulation has a much bigger effect: insulating the roof and walls can cut the heating cost by 30\u201350%.<\/p>\n<h2>A real example: how one family cut its heating cost by 30%<\/h2>\n<p>Take an 85 m\u00b2 apartment in Vake, on the fifth floor of a 1980s building. The family used a gas boiler and paid 150\u2013170 GEL a month for gas in winter. In autumn they took three simple steps: replaced old windows with modern double glazing, had the boiler serviced and installed a programmable thermostat.<\/p>\n<p>The following winter the monthly bill fell to 105\u2013120 GEL, about 30% less. The thermostat and servicing cost under 300 GEL and paid for themselves in the first season. The windows were more expensive, but comfort improved a lot: the drafts and the cold near the windows disappeared.<\/p>\n<h2>5 myths about heating cost<\/h2>\n<h3>Myth 1: &#8220;Leaving the boiler on all day is cheaper than switching it on and off&#8221;<\/h3>\n<p>Partly true, but only if someone is always home. If the family is at work during the day, lowering the temperature by 3\u20134\u00b0C with a thermostat is more economical than heating an empty apartment. The key is not to switch the boiler off completely and let the apartment get cold, because reheating the walls takes a lot of energy.<\/p>\n<h3>Myth 2: &#8220;Oil radiators are economical&#8221;<\/h3>\n<p>Oil radiators, convectors and any other electric heaters turn 1 kWh of electricity into exactly 1 kWh of heat. The difference is only in how heat is distributed, not in efficiency, so their heating cost is about the same and the highest of all systems.<\/p>\n<h3>Myth 3: &#8220;Opening a window for ventilation wastes heat&#8221;<\/h3>\n<p>A window left open for a long time does raise the heating cost, but a full 5\u201310 minute airing twice a day is essential to prevent damp and mold. Dry air heats up faster, so short, proper ventilation barely affects the bill.<\/p>\n<h3>Myth 4: &#8220;A new building hardly needs heating&#8221;<\/h3>\n<p>A new building does not always mean good insulation. Many fa\u00e7ades are uninsulated and the windows are often the developer&#8217;s cheapest choice. Before buying, ask what insulation the walls have and what windows are installed.<\/p>\n<h3>Myth 5: &#8220;An inverter doesn&#8217;t heat in winter&#8221;<\/h3>\n<p>Old and cheap models do struggle in frost, but modern inverter air conditioners, especially winter-rated series, heat efficiently down to \u221215\u00b0C. That is more than enough for Tbilisi&#8217;s climate.<\/p>\n<h2>Heating cost and renovation: decide in advance<\/h2>\n<p>If you are renovating now, this is the best time to reduce your future heating cost. After the renovation, many changes become far more expensive because they mean damaging walls and floors. Plan radiator positions under windows and insulated pipes, decide on underfloor heating before the screed, consider thin internal insulation on external walls in corner or top-floor apartments, replace windows before finishing the reveals, and size the wiring correctly if you plan to heat with inverters. You can estimate the cost of a heating system in <a href=\"https:\/\/datvale.ge\/en\/\">Datvale<\/a>&#8216;s <a href=\"https:\/\/datvale.ge\/en\/renovation-calculator\/\">renovation calculator<\/a>.<\/p>\n<h3>Summary<\/h3>\n<p>In 2026, the gas boiler still has the lowest monthly heating cost in Georgia: about 450\u2013500 GEL per season for an 80 m\u00b2 apartment. An inverter air conditioner costs 30\u201340% more to run but less to install and also cools in summer, so over 10 years its total cost is almost equal to gas. Electric convectors are only suitable as backup heating. Whatever you choose, the biggest savings come from insulation, good windows, a thermostat and regular servicing, steps that often cut the heating cost by 20\u201330% while making your home more comfortable.<\/p>\n<h2>How to cut your heating cost by 20\u201330%<\/h2>\n<ol>\n<li>Seal windows and doors \u2014 a large part of heat is lost there.<\/li>\n<li>Install a room thermostat and lower the temperature by 2\u20133 degrees at night.<\/li>\n<li>Don&#8217;t block radiators with furniture or curtains.<\/li>\n<li>Service your boiler every autumn.<\/li>\n<li>Insulating the external wall, if possible, gives the biggest savings.<\/li>\n<\/ol>\n<div class=\"dv-cta\">\n<h3>Calculate the cost of your heating system<\/h3>\n<p>Enter the number of radiators and boiler class \u2014 get an approximate installation cost.<\/p>\n<p><a href=\"https:\/\/datvale.ge\/en\/plumbing-heating-calculator\/\">Heating calculator \u2192<\/a><\/div>\n<h2>Frequently asked questions<\/h2>\n<div class=\"dv-faq\">\n<h3>What is the heating cost of an 80 m\u00b2 apartment with gas?<\/h3>\n<p>With average insulation, about 450\u2013500 GEL per season, or 90\u2013100 GEL per month.<\/p>\n<\/div>\n<div class=\"dv-faq\">\n<h3>Is heating with an air conditioner cheap?<\/h3>\n<p>An inverter air conditioner is about 3 times cheaper than an electric heater, but 30\u201350% more expensive than a gas boiler.<\/p>\n<\/div>\n<div class=\"dv-faq\">\n<h3>Did electricity get more expensive in Georgia in 2026?<\/h3>\n<p>Yes, from 1 April 2026 the household tariff increased and in Tbilisi it is \u2248 20\u201328.5 tetri per kWh, depending on consumption.<\/p>\n<\/div>\n<div class=\"dv-faq\">\n<h3>What is the cheapest heating to install?<\/h3>\n<p>Electric convectors, although their monthly cost is the highest.
