Boiler Accessories

Versatility for all demandsIn connection with our condensing boiler and low-temperature program we off extensive and precisely coordinated accessories for virtually any situation.

The controls of the THETA series are particularly distin-guished 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.

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 (two-wire bus).

The Intercal heating circuit pump groups with and wit-hout mixers – consisting of top-grade brass parts and brand components (pump, actuator) – are the optimal supplements for any boiler. The optional system acces-sories (e.g. connection pipework and distributor bars) can be easily adapted to any heating system.

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.

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.

We also offer further accessories such as diaphragm-type expansion tanks, sound cabinets, fixed bases (boiler base), storage thermometers and digital room thermometers.

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 re-trofitting). For instance, our blue-flame burner from the BNR series turns any boiler into an efficient condensing heat system.

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 expan-ding 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.
