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.
