Innovative heat exchanger design Allows for a compact and easy to install unit

Whatever the application, the Redring Powerstream Professional electric flow boiler provides an efficient, versatile and safe way of quickly heating water.

Suitable for both vented and unvented wet central heating and domestic hot water systems wherever there's mains electricity.

There are over two million homes in Britain with no mains gas supply as well as other rural homes, new housing projects and multi-floor dwellings that would benefit from the flexibility of a modern electric boiler.

Used as a direct replacement for Gas, Oil, Propane, Solid Fuel or Electric Storage heating, the Powerstream Professional flow boiler provides a practical way of delivering hot water and heating to any home and can be used with standard ‘wet’ system radiators, underfloor heating, programmers, pumps, room stats and thermostatic radiator valves.

There are seven models in the range to suit the majority of applications, including sealed and open vented installations. In addition, the flow boiler can provide domestic hot water when used in conjunction with an indirect hot water storage cylinder.

The Redring Powerstream Professional delivers the industry standard where Gas, Oil, Propane or Solid Fuel is not available; or fluing restrictions prevent the use of boilers that use these fuels. The wet central heating system boiler does not require costly servicing and safety checks, has no need of any flue system and as such provides the maximum flexibility in terms of boiler location.

The Powerstream Professional flow boiler is 99.8% efficient and silent in operation. It quickly produces hot water by circulating water over electric heating elements and its thermostatic temperature operation is adjustable from 30°C to 80°C. It is suitable for a wide range of properties including mobile homes, flats, apartments, family houses and light commercial properties.

Boiler Sizing: Please consult your installer/heating engineer/designer as to the correct size of Powerstream Professional boiler. Size of the property, the insulation properties of the

building itself, the local and seasonal weather conditions and exactly what the boiler will be required to heat eg: heating and/or hot water will need to be considered. To discuss

individual delivery and design requirements or for help with making your selection please call: Technical - 08709 000430 or e-mail Design - AEDESIGN@applied-energy.com
