Direct Cylinders - Main Heating

At Fuel Tank Shop, we have a wide range of high-quality and reliable direct cylinders from leading manufacturers such as Kingspan, Main, Megaflo and Heatrae Sadia. Known for their simplicity and efficiency, direct hot water cylinders come equipped with an electric immersion heater or heating element that can heat water rapidly. When you turn on a hot water tap, the immersion heater inside the cylinder quickly heats the water, ensuring you have almost instant access to hot water.

Available in a range of capacities, from 70 to 300 litres, our direct cylinders are easy to install and maintain. Since they do not require a separate heat source like a boiler or external heat pump, there are fewer components and systems involved, making them straightforward and cost-effective to set up. Maintenance usually involves periodic checks and replacement of the immersion heater if needed.

Choose a slimline direct unvented hot water cylinder if you are limited on space. By being taller and slimmer, these cylinders don’t necessary compromise on capacity – holding the same amount of hot water as an equivalent capacity cylinder. Be aware, our direct cylinders are heated via an electric immersion and do not work with gas, oil, or heat pump systems.
