Cyclone Direct Cylinders are designed to work with electricity only. The water is heated using electrical elements and they do not have any ability to heated by oil or gas boilers.
Immersion Heater Options
Incoloy immersions come as standard in all Joule Cyclone Cylinders unless otherwise stated. Incoloy immersions are designed for low to medium use in a domestic application. If the water been stored is hard or the usage is high, Joule recommend Titanium Immersions.
With the requirement for more energy efficient solutions, Joule offer the full Cyclone range with Eco80 specification. The eco 80 range increased insulation thickness to 80mm nominal.
