Everflo Stainless Indirect Unvented Hot Water Storage Cylinder & Kit
The Everflo Stainless Indirect Unvented Cylinder is engineered to deliver fast, efficient and reliable hot water for a wide variety of homes and small commercial properties. Designed to heat up quickly and retain heat for long periods, it ensures you always have a dependable supply — whether it’s for a single shower or a busy facility such as a sports pavilion.
These indirect cylinders work alongside a traditional boiler system (gas, oil or electric), but also come equipped with a built-in immersion heater for backup heating. This ensures hot water is available even if the main boiler is offline. Made from high-quality duplex stainless steel and available in capacities from 90L to 300L, Everflo provides long-lasting performance with options suited to both smaller households and high-demand environments.

FAQs
What is the difference between direct and indirect cylinders?
Indirect cylinders are heated via a coil connected to your boiler, whereas direct cylinders rely on immersion heaters as the primary heat source. Indirect systems tend to heat faster and more efficiently when paired with a boiler.
Is the Everflo Indirect cylinder suitable for large families?
Yes — with sizes up to 300L, the range is perfect for homes with multiple bathrooms or properties with high hot water usage.
Do I still get hot water if my boiler fails?
Absolutely. Each cylinder includes a built-in immersion heater that provides backup heating whenever the boiler is unavailable.
