The Vaillant ecoTEC Plus 424 is an exceptionally reliable 24kW open-vented, heat-only boiler designed specifically for properties reliant on traditional heating architectures with a cold water storage tank. It incorporates a premium aluminium heat exchanger to facilitate rapid thermal conductivity and robust longevity. Delivering a central heating output of 25.7kW, this highly efficient appliance operates with a wide modulation range of up to 1:6. This capability allows the burner to precisely match fluctuating heat demands, significantly lowering unnecessary gas consumption and maintaining an impressive ErP A rating with an 89.2% SAP 2009 efficiency score.
Presenting an ultra-compact and lightweight profile, the unit measures just 602mm in height, 375mm in width, and 320mm in depth, with a lift weight of only 23kg. This incredibly small footprint ensures seamless integration into kitchen cupboards, while the push-fit flue system provides enhanced routing flexibility during installation. The boiler is fully Quiet Mark accredited, guaranteeing minimal acoustic output during operation. Furthermore, it integrates two-stage frost protection to defend the system during freezing temperatures, alongside push-button programming for streamlined parameter adjustments.
Q: What is the modulation capability of this open-vent boiler?
A: The appliance features a wide modulation range of up to 1:6, adjusting its output to match exact heating demands.
Q: Does this model require a sealed central heating system?
A: No, this is a heat-only regular boiler designed specifically for traditional open-vented systems with cold water tanks.
Q: What material is the primary heat exchanger constructed from?
A: It utilises a highly efficient and durable aluminium heat exchanger for rapid thermal transfer.
Q: Are the flue connections difficult to assemble?
A: It utilises a push-fit flue system to provide quick, secure, and highly flexible exhaust routing during installation.
