OSO Super Xpress SX(D)

- Unique pioneering design. All pipes & cables hidden

The Super Xpress has a unique, integrated expansion solution factory fitted. All pipes & connections are also hidden under an insulated top lid. Factory fitted components drastically reduces fitting time, making the Super Series virtually a pre-plumbed unit. Duplex Stainless Steel makes the Super Series extremely lightweight & space efficient for easy handling & installation. Low heat loss, dedicated secondary return, impressive heat up & recovery times and a 25 year guarantee.

The Super Xpress is a quantum leap in unvented cylinder design. All pipes, expansion vessels and electric cables are hidden from view beneath an insulated removable lid giving the neatest possible installation. A bespoke multifunction valve, including a unique blending valve is factory fitted with the supplied expansion vessels to make the Super Xpress virtually a pre-plumbed unit. Adjustable feet are also integrated.

The SX heats to 70°C, with water then blended to 60°C when drawn off, increasing available hot water compared to others.

Cylinders from 150 litres are fitted with twin immersion heaters, suitable for off-peak tariffs.

All pipes connect to the Super SX from the rear, allowing them to be concealed from view. The installer fits the pipes to the back wall together according to a supplied template and finally slides the cylinder into place to marry the valve connections with the pre-cut pipe tails.

Key advantages:

  • Unique, integrated and factory fitted expansion solution and control valve.
  • Superior heat up & recovery times and suitable for off-peak tariffs.
  • Laser welded Duplex steel, OSO ECO Foam insulation and 25 year guarantee.

Choose volume

Super Xpress is available in 6 different volumes, estimated to be suitable for the no. of people designated in the table below. The table shows suitable volumes based on experience from average hot water usage in a normal household. If the household has a large hotwater usage, for instance due to large bathtubs, steamshowers etc., one should choose higher volume than designated in the table. Hotwater capacity is calculated by instant tapping at 40°C. At 40°C a normal shower uses approx. 60 l., bathtubs 180 l. and bubblebaths 400 l.
