Boiler Accessories
Versatility for all
demands
In connection with our condensing boiler and lowtemperature
program we off extensive and precisely
coordinated accessories for virtually any situation.
The controls of the THETA series are particularly distinguished
by their extreme user friendliness. The heating
system can be configured to the needs of the operator
in just a few simple steps. A plain-text menu guides the
operator through the entire process.
The THETA series can also realize complex control
requirements.
The Intercal heating circuit pump groups with and without
mixers – consisting of top-grade brass parts and
brand components (pump, actuator) – are the optimal
supplements for any boiler. The optional system accessories
(e.g. connection pipework and distributor bars)
can be easily adapted to any heating system.
The Intercal ECODENS stainless steel flue gas heat
exchanger is the simple and energy-efficient solution for
any oil or gas heating system (also very suitable for retrofitting).
For instance, our blue-flame burner from the
BNR series turns any boiler into an efficient condensing
heat system.
By combining the controls of the THETA series with the
illuminated remote controls of THETA RSL, you can
query the operating status of your boiler with a practical
remote control and comfortably configure your room
settings and virtually all other parameters.
THETA RSL is connected via a twin-axial cable (twowire
bus).
The entire system from one source – various hydraulics
groups for virtually all system requirements consist of
the very highest quality components. Our product range
provides solutions for safety groups, storage supply
pump sets for horizontal and floor-standing storages as
well as several other connections solutions.
From the basement to the roof – for our condensing
boiler systems ECOHEAT Oil, ECOHEAT plus and the
ECODENS stainless steel flue gas heat exchangers,
we offer complete flue gas systems made of plastic.
This facilitates easy and quick installation and it is also
a cost-effective solution for the renovation of flue gas
systems.
The wall-mounted case THETA MSK is used for expanding
a control system or retrofitting an existing heating
system. This case can accommodate THETA controls
up to the maximum configuration (THETA 2233 BVV).
All ultimate consumers (pumps, mixers, etc.) can be
connection without any additional wiring required.
We also offer further accessories such as diaphragmtype
expansion tanks, sound cabinets, fixed bases
(boiler base), storage thermometers and digital room
thermometers.
With the optional flue gas sound absorbers made of
stainless steel, Intercal boilers are also very suitable
for difficult installation situations within living quarters.
Its patented T-shaped design makes it an excellent
solution for very small boilers rooms.
