Important: Recent projects involving adding ~ 20% hydrogen to natural gas and transporting it through pipes to boilers are impractical, fail to significantly reduce carbon emissions, and perpetuate dependence on natural gas. They are not sustainable in the long term. We classify these boilers as gas boilers.
| Feature | Hydrogen Plasma Combi Boiler | Natural Gas Combi Boiler |
|---|---|---|
| Operating System | Produces hydrogen on-demand by converting the water inside its boiler into hydrogen plasma using its plasma technology. No hydrogen storage, no pipelines, no external supply needed, and zero safety risks. | Relies on external natural gas supply via pipelines. Requires regular gas delivery infrastructure, which introduces safety risks and dependency on supply chains. |
| Fuel Independence | Provides fuel independence, as it only needs water and electricity (which can come from renewables). | Fully dependent on external gas supply through pipelines, leading to potential risks during disruptions or price fluctuations. |
| Energy Input | Uses water (for hydrogen) and electricity, with 65% lower electricity consumption compared to electric boilers. When paired with solar, wind, or geothermal, operational energy costs are nearly zero. | Requires natural gas as the primary fuel, with electricity used for ignition and system controls. Heating efficiency depends on a continuous gas supply. |
| Efficiency | Hydrogen plasma technology allows rapid heat production with almost 200% energy efficiency (Coefficient of Performance or COP of 2). Lotus Hydrogen Plasma combi Boilers are also 65% more efficient than standard electric boilers, with instant heating and no energy losses. | Modern gas combi boilers are typically 90% efficient (COP 0.9). However, they are less efficient over time due to energy losses in combustion and gas leakage. |
| Set Temperature Reach Time | Fast response time with almost instant heat generation via hydrogen plasma combustion. Temperature control is more precise. | Slower to reach the desired temperature due to the nature of gas combustion. Heating takes much longer compared to plasma systems. |
| Carbon Emissions | Zero carbon emissions during the heating process. The only byproduct is water vapor, and 1 - 2 liters of water is used per year because the combustion process takes place in a closed environment, and the steam turns back into water. | Produces significant carbon emissions during combustion. Emits CO₂ and other harmful gases, contributing to climate change. A ventilation shaft is required. |
| Fuel Cost and Price Fluctuation | The only cost is a small amount of electricity for the plasma process, which will be free if powered by renewable energy sources. | Exposed to natural gas price fluctuations. Fuel bills depend on global gas market trends, with high costs during shortages or crises. |
| Carbon Footprint | Zero carbon footprint during the combustion and heating process. | High carbon footprint due to natural gas combustion and methane leakage from pipelines. |
| Maintenance | Minimal maintenance: Annual water level check (1-1.5 liters vapor loss). No moving parts or resistances prone to wear. It is a compact, plug-in device. | Requires regular maintenance to ensure gas safety and system efficiency. Risks include gas leaks, clogged burners, and scaling of heat exchangers. |
| Installation Complexity and Safety | Installation is simple: No gas connections, pipelines, or storage tanks required. Safe operation without the risks associated with gas storage or supply disruptions. | Installation requires specialized gas connections, pipelines, and ventilation to ensure safe operation. Risk of gas leaks and explosion hazards. |
| Economy (Cost of Operation) | Extremely low operational costs, especially when paired with renewables. For a 100 m² space, it uses 6 kW/hour and runs for only 5 hours daily (compared to 18 - 24 kW/hour for electric boilers). | Moderate fuel costs but subject to volatile gas prices. Operational costs rise if gas prices increase or during cold seasons with high heating demands. |
| Environmental Impact | Eco-friendly: Zero emissions, no external fuel needed, and no impact on air quality. | Negative environmental impact due to CO₂, NOₓ emissions, and methane leaks. Natural gas extraction and transportation also harm ecosystems. |
| Flexibility and Scalability | Highly flexible: Can be integrated with solar, wind, or geothermal energy to operate off-grid with zero electric payments. Scalable for both small homes and up to buildings of thousands of square meters. | Limited flexibility: Fully dependent on a gas supply. Not suitable for off-grid operation unless combined with alternative heating sources. |
| Productivity and Output | Provides continuous, on-demand heat with stable performance regardless of weather or external conditions. | Performance may degrade in areas with low gas pressure or during high-demand periods in winter times. |
