What are Non-Condensing Boilers? 

Non-condensing boilers represent a conventional approach to heating, where fuel is burned to heat water. This process emits hot flue gases expelled through a chimney, resulting in heat loss. In contrast to condensing boilers, non-condensing types do not recycle this heat, which makes them comparatively less efficient.

Common boiler types include conventional boilers, ideal for homes with high water demands due to their separate hot water cylinder and storage tanks. System boilers integrate most components, saving space, while combi boilers deliver heating and hot water directly, making them perfect for smaller spaces.

Non-condensing boilers are appreciated for their straightforward design, ease of maintenance, and cost-effectiveness, especially in older structures. Yet, their energy efficiency levels, typically between 80-90%, contribute to higher operational expenses and a more substantial environmental footprint than condensing boilers. Tevis Energy advises weighing these factors alongside your specific requirements and the long-term advantages of opting for a more efficient system when selecting a boiler.

Exploring Condensing Boilers 

Condensing boilers represent a contemporary, highly efficient boiler type. Their defining characteristic is the ability to capture and recycle heat from water vapor in exhaust gases, distinguishing them from their non-condensing counterparts. This capability enables condensing boilers to reach 90% or higher efficiencies, enhancing their effectiveness in converting fuel to usable heat. Including a condenser and an additional heat exchanger is integral to achieving this elevated efficiency.

While condensing boilers may have a higher initial cost and sometimes require modifications like a new flue system, their long-term advantages are substantial. These boilers help decrease energy bills and contribute to environmental conservation by emitting fewer greenhouse gases. Tevis Energy recommends considering these benefits in conjunction with your heating needs and the current system configuration to assess whether a condensing boiler is a prudent investment for your requirements.
