Signat Powerstream Professional User Manual

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.
