The Vaillant ecoFIT Pure 630 is an ultra-compact 30kW system boiler developed to deliver robust and highly efficient central heating for domestic properties equipped with a separate hot water storage cylinder. Operating with a powerful central heating output of 31.8kW, this unit is built around a high-specification aluminium heat exchanger. This component utilises 4-sided cooling and water agitation to drastically reduce thermal stress, thereby extending the operational lifespan and maintaining up to 94% ErP A-rated efficiency. When full capacity is unnecessary, the boiler can modulate down to 20% of its maximum output, substantially lowering fuel consumption during periods of reduced demand.

Engineered for exceptional siting flexibility, the appliance measures 700mm by 390mm by 295mm and weighs just 31kg, making it perfectly suited for standard cupboard installations. It uniquely supports both top and rear flue configurations, allowing for unobtrusive pipe routing in diverse property layouts, with industry-leading flue lengths extending up to 10m. All internal components are accessible from the front, and the side panels are fully removable to streamline routine servicing. The clear LED display ensures fault codes remain highly visible, even in poorly lit environments.

Q: Does this model support rear flue installations?
A: Yes, it accommodates both top and rear flue configurations to maximise siting flexibility in restrictive spaces.

Q: How far can the boiler modulate its heat output?
A: The system can modulate its output down to 20% of its maximum capacity to reduce unnecessary fuel consumption.

Q: What material is utilised for the heat exchanger?
A: It features a high-specification aluminium heat exchanger with 4-sided cooling to minimise operational stress.

Q: What is the maximum supported flue length?
A: The appliance supports extensive flue runs of up to 10m to accommodate complex exhaust routing.
