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.
