Product Information

Baxi Direct Unvented Cylinder

The Baxi Direct Unvented Cylinder is a dependable hot water solution for homes that are not connected to the mains gas network. As a direct cylinder, it uses an immersion heater to heat the stored water, making it a practical choice for properties that require an electric hot water system. The range is available in 125L, 170L and 210L capacities, providing options for different household hot water requirements. Whether you're looking for a more compact cylinder for a smaller property or additional storage for a higher-demand home, the range offers a suitable capacity.

Efficient Hot Water Storage

With 50mm-thick insulation, the cylinder is designed to reduce heat loss and help keep stored water hotter for longer. This helps improve heat retention and can contribute to more efficient energy use. The cylinder can provide hot water flow rates of up to 76 litres per minute at 3 bar pressure, making it well suited to applications where strong water flow is important, including powerful showers and faster bath filling.

Space-Saving Installation

The Baxi Direct Unvented Cylinder features an internal floating baffle expansion system, eliminating the need for a separate expansion vessel. This creates a neater installation and helps save valuable space. The internal expansion design can also make installation quicker and easier, particularly where available installation space is limited.

Durable Construction

The cylinder is manufactured from high-grade duplex stainless steel, providing excellent corrosion resistance and a strong strength-to-weight ratio. This durable construction is designed to support reliable performance over the long term. The inner tank is covered by a 15-year warranty, while other components have a 2-year warranty, subject to the manufacturer's applicable terms and conditions.

Available Capacities

The Baxi Direct Unvented Cylinder range is available in three capacities:
  • 125L – a compact option for homes with moderate hot water requirements.
  • 170L – provides additional stored hot water for households with greater demand.

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time. You'll receive tracking details once your order has been dispatched, and if we need to confirm any delivery details, one of our team will contact you directly to keep everything running smoothly.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.

If you're ordering multiple products from the same supplier, your order will be dispatched together once all items are ready. This means the longest lead time will apply.
