Available in six sizes from 120 to 300 litres to suit the vast majority of domestic installations, the Warmflow Indirect models are the core of our cylinder range. Thanks to the large surface area, high performance heat exchanger coils the Indirect models boast impressive heat up times - the 180 litre model taking just 25 minutes to reach 60ºC from cold.
The Indirect models, like the rest of the range, are designed to be fed directly from the mains water supply via the inlet group supplied, which is capable of receiving incoming water at pressures up to a maximum of 12 bar.
In order to achieve the best performance from our unvented cylinders the mains water supply must be capable of supplying a flow rate of at least 20 litres per minute with a dynamic pressure of at least 1.5 bar. Should the supply performance be less than this the hot water flow rates will be reduced, however a Warmflow unvented cylinder may still be installed and the benefits of a fast heat up time and minimal heat losses can still be enjoyed.
- Provides a cold water capacity of 205L for standard unvented installations.
- Includes a 3kW Incoloy immersion heater with a 22-minute EN12897 heat-up time.
- Requires a minimum supply flow rate of 20L/min at 1.5Bar dynamic pressure.
- Measures 544mm in diameter and weighs 50kg before filling.
- Supplied with an expansion vessel and holds a C energy efficiency rating.
