The Vaillant ecoTEC Pro 24kW combination boiler is an advanced, wall-mounted heating unit tailored for smaller domestic properties requiring immediate hot water delivery. It utilises a patented stainless steel heat exchanger to ensure superior thermal transfer and long-term operational resilience. With a central heating output of 24.8kW and a domestic hot water output of 23.4kW, the appliance provides a reliable flow rate of 9.6l/min. It achieves an ErP A rating for both heating and hot water, integrating a high-efficiency modulating Grundfos pump that adapts intelligently to precise system demands to lower electricity consumption.

To facilitate straightforward installation and servicing, the unit features removable side panels and front-facing component access. It measures 720mm by 440mm by 338mm, weighing 38kg. The boiler features an expansive modulation range of up to 1:5, which precisely matches heat output to demand and reduces fuel usage during milder conditions. Additional attributes include Vaillant's aquaCOMFORT warm start feature for rapid hot water delivery, built-in two-stage frost protection for reliable winter operation, and Quiet Mark accreditation for low-noise functionality.
