For many years now, suspendedunit air heaters have beenemployed worldwide to heatindustrial buildings. Researchfrom the ‘Gasunie’ (NL) regardingvarious industrial heatingsystems has confirmed thatdirect heated gas-fired air heating is one of the most efficient heating methods.
In general
The Winterwarm HR series (high
system efficiency) combines efficien-
cy, energy savings and total comfort
control through several unique design
characteristics. The OpenTherm con-
trol makes it easy to operate the
heater and realise a comfortable
environment in the room.
Technical features
The HR is a condensing unit air
heater with axial fan. The efficiency
of the heaters is more than 106%.
The premix burner allows the heater
to modulate back to 20% of its
maximum capacity. This implicates
that the heater can very precisely
adjust its heat output to the demand
received through the room thermostat.
Therefore the energy consumption is
as low as possible. As the range of the
HR-series goes up to 150 kW, a lot of
energy can be saved by applying an
HR-heater instead of a conventional
unit air heater. Measurements by the
dutch national gas institute have
proven that these savings can add up
to 25%!
The heat exchanger is made from high
grade stainless steel and has a
guarantee period of 5 years.
Condensation discharge
The HR heaters can realize an output
of 106 %. This high efficiency requi-
res a condensation discharge system
which is located at the bottom of the
heater. For the installation on the
heater unit a siphon is supplied. Any
further required drain pipes are not
supplied. This means that an extra
siphon or gooseneck is required to be
fitted before the sewage.
Suspension
The HR is provided with 4 suspension
points M10 on top of the heater. A set
of solid cantilever brackets can be
ordered along to suspend the heater
from the wall. The heater can be
either suspended from these brackets,
or be placed on top of them. This sus-
pension set consists of 2 U-sections
with 2 supports. For suspension from
the ceiling threaded bar M10 can be
used.

Flue terminal
The installation of the combustion air
supply and the combustion gas
discharge must meet the general
prescriptions for high efficiency flue
terminals. Winterwarm has a complete
range of stainless steel flue terminals
and extra lenghts/bends available.
As the HR is provided with a flue
booster one can apply either a
horizontal (wall) or a vertical (roof)
flue terminal. The length of the flue
should not exceed 10 m taking into
account that each 45˚ elbow counts as
1 m length and each 90˚ elbow counts
as 2 m length. The dimensions of the
flue is 80, 100 or 130 depending on
the type of heater.
Controls
The HR heaters are provided with a
OpenTherm protocol, controled by an
OpenTherm clock thermostat. This is
a low voltage clock thermostat which
is programmable per day and can con-
trol 1 heater. Also it is provided with
frost protection, summer ventilation
position and a reset function.
If desired, a remote sensor can be
attached so that the control can
be placed elsewhere.
