Slimline and standard range options available

The slimline models are available in 90, 120, 150, 175 and 210 litre capacities with a compact 490mm diameter. For installations requiring larger storage, the standard diameter models are available in 250 and 300 litre capacities with a 580mm diameter.​​The uniSTOR pure direct cylinder offers an external expansion vessel.Each cylinder features either one or two 3kW titanium heating elements as standard to ensure performance is optimised even in aggressive water conditions. The 304 duplex stainless steel inner tank ensures strength and corrosion resistance, while front-facing bosses make connections straightforward with ease of access.

Labelled connections for simplicity

Easy-to-recognise, giving onsite guidance for installation and maintenance. Hot and cold water 22mm connections are clearly identified in the front third of the cylinder, with a maximum 5mm clearance at the back for cupboard fit.

Carry handle and tilt protection belt

Allows for easy 2-person lifting and manoeuvring into tight spaces. A belt has been included with every cylinder, helping prevent movement or damage and to ensure stability after installation.
