コンビボイラー市場 - 世界の産業規模、シェア、動向、機会、予測：燃料別、技術別、用途別、地域別、競合別、2020～2030年

世界のコンビボイラーの市場規模は2024年に367億7,000万米ドルで、予測期間中のCAGRは7.52%で2030年には523億2,000万米ドルに達すると予測されています。

世界のコンビボイラー市場は、エネルギー効率が高く省スペースの暖房ソリューションに対する需要の高まりにより、住宅および商業分野で着実な成長を遂げています。コンビボイラー（コンビネーションボイラー）は、セントラルヒーティングと給湯の2つの機能を備え、個別の給水タンクやボンベを必要としません。そのため、特にスペースに制約のある都市部の住宅にとっては、非常に魅力的なものとなっています。二酸化炭素排出量の削減とエネルギー効率の向上が世界的に重視されるようになったことで、従来のモデルよりも大幅に効率的な凝縮式コンビボイラーの採用が加速しています。各国政府が厳しいエネルギー規制を施行し、環境に優しい家庭用暖房システムに補助金を支給しているため、メーカーはこうした基準を満たす先進的な凝縮技術の開発に注力しています。

さらに、ゼロカーボン住宅の推進や、欧州数カ国における石油焚きボイラーの禁止予定が、市場をさらに後押ししています。北米、特に米国とカナダでも、特に改修用途や小規模住宅でコンビボイラーへの関心が高まっています。アジア太平洋地域では、中国、インド、韓国のような国々における都市化の進展、住宅建設の成長、生活水準の向上が市場拡大の新たな機会を生み出しています。しかし、同地域は農村部、特にガス供給網に関するインフラの制約に依然として直面しており、これが普及を阻害している可能性があります。

Global Combi Boiler Market was valued at USD 36.77 Billion in 2024 and is expected to reach USD 52.32 Billion by 2030 with a CAGR of 7.52% during the forecast period.

The global Combi Boiler Market is experiencing steady growth, driven by increasing demand for energy-efficient and space-saving heating solutions across residential and commercial sectors. Combi boilers, or combination boilers, serve dual functions providing both central heating and hot water-without the need for separate water tanks or cylinders. This makes them highly attractive for urban housing, especially in space-constrained environments. The growing global emphasis on reducing carbon emissions and improving energy efficiency has accelerated the adoption of condensing combi boilers, which are significantly more efficient than traditional models. As governments around the world enforce stringent energy regulations and offer subsidies for eco-friendly home heating systems, manufacturers are focusing on developing advanced condensing technologies that meet these standards.

Moreover, the push for zero-carbon homes and upcoming bans on oil-fired boilers in several European countries are further propelling the market. North America, particularly the United States and Canada, is also witnessing increased interest in combi boilers, especially in retrofit applications and smaller homes. In Asia Pacific, rising urbanization, growth in residential construction, and improving living standards in countries like China, India, and South Korea are creating new opportunities for market expansion. However, the region still faces infrastructural limitations in rural areas, particularly regarding gas supply networks, which can inhibit widespread adoption.

Key Market Drivers

Stringent Energy Efficiency Regulations and Incentives

Government mandates and global policies aimed at reducing carbon emissions have significantly boosted demand for energy-efficient heating systems like combi boilers. Many countries require newly installed boilers to meet minimum energy efficiency thresholds of 90-92%. In Europe, approximately 75% of all new residential boilers installed in 2023 were condensing combi boilers due to compliance requirements. Switching from a non-condensing to a condensing model can result in energy savings of up to 30% annually. In the UK, households upgrading from older G-rated boilers to modern A-rated condensing boilers can save around euro490 per year on energy bills. Additionally, eco-incentives such as government grants of up to euro2,500 have encouraged widespread adoption among low-income households. Energy performance certificates (EPCs) required for home rentals and sales further push boiler upgrades, with 60% of property owners listing energy-efficient boilers as key to compliance.

Key Market Challenges

High Initial Installation and Upgrade Costs

Despite long-term energy savings, the high upfront cost of combi boilers remains a key barrier to widespread adoption, particularly in price-sensitive markets. Installing a modern condensing combi boiler can cost between USD2,500 and USD5,000, depending on size, model, and region. In many developing countries, this cost is unaffordable for average homeowners, making traditional heating systems more attractive in the short term. Even in mature markets, replacement costs including labor, pipework, and system upgrades deter some consumers from switching, especially in older properties with incompatible infrastructure. In commercial applications, retrofitting large buildings with combi systems requires a significant overhaul, often exceeding budget allocations. Financial constraints are further exacerbated when integrating smart controls or hybrid systems, which increase initial investment by 10-20%. For landlords or housing associations managing multiple properties, these costs multiply, discouraging fleet-wide upgrades. Although government subsidies and financing options exist in some regions, they are often not uniform or accessible enough to offset the financial burden for all consumers. As a result, many potential buyers delay boiler upgrades, slowing down the replacement cycle and hindering market momentum.

Key Market Trends

Rise of Smart and Connected Combi Boilers

The combi boiler market is undergoing a technological transformation with the integration of smart and IoT-enabled features. These innovations allow users to control, monitor, and optimize their heating systems remotely via mobile apps and voice assistants. In 2024, nearly 50% of new combi boilers sold in Europe and North America were equipped with smart capabilities. This includes learning thermostats, weather-responsive operation, energy consumption analytics, and automated fault diagnostics. Homeowners now expect their boilers to be part of a broader connected ecosystem, offering convenience, energy savings, and predictive maintenance alerts. Smart-enabled combi boilers can reduce energy bills by 10-25% by tailoring performance to user behavior and real-time climate conditions. Manufacturers are partnering with home automation companies to deliver integrated solutions-some even providing subscription-based platforms for energy management. Demand is particularly high among millennial and Gen Z homeowners, who prioritize digital convenience and sustainability. Commercial buildings are also adopting these systems for centralized control of heating across multiple zones. This trend is driving a new wave of product development, with companies investing in wireless connectivity, firmware updates, and cloud-based diagnostics. Additionally, many governments and utility providers are encouraging smart boiler adoption through incentives and energy-efficiency rebate programs. As connectivity becomes a standard expectation in home appliances, the smart combi boiler segment is set to be a primary growth engine in the coming years.
