  • Charging valve ESBE VTC412 50°C


    ESBE's thermal valves in the VTC400 series are designed for applications with boilers that require regulation of the return temperature. By maintaining a high and constant return temperature, you obtain a higher efficiency, reduced tar formation and a longer life for the boiler or stove.

    • Exact regulation of the return water temperature
    • High Kvs value
    • Available with fixed and adjustable temperature settings
    • Wide temperature range
  • ESBE CRB221 Wireless Controller


    The ESBE CRB221 regulates your temperature in the house wirelessly, allowing you to easily increase comfort and save up to 20% energy (source: Swedish consumer magazine Råd&Rön). Now in updated version from the previous model ESBE CRB122.

    The room unit sends continuous feedback to the actuator unit, which adjusts the shunt valve according to the desired target temperature.

    With the built-in timer, with daily and weekly programs, it is possible to set different day and night temperatures for further energy savings.

  • ESBE Valve combination VMB423


    Valve combination with safety valve intended for hot water storage. Incoming cold water has reverse and shut-off function as well as connections for vacuum valve etc. Incoming hot water is regulated within the temperature range 35-60°C through a thermostatic mixing valve series VTA320.

  • Fitting kit Termoventiler AS, 1.5 bar


    Complete Valve Set for Safe and Efficient Heating Systems. Termoventiler AS is a complete valve set that provides you with safety and performance in your heating system. It includes all the necessary components to ensure a proper installation and functioning operation: a brass collection pipe, a high-lift safety valve with an EPDM membrane seal, an automatic air vent with a backflow preventer and a PTFE seal, and a pressure gauge DN50 cl 1.6%.

    Safety and Performance

    Termoventiler AS is designed to meet high safety standards and provide high performance. The safety valve is sized to handle the capacity of the system and has a membrane seal that guarantees a tight closure when needed. The air vent with backflow preventer and PTFE seal prevents air from entering the system and contributes to efficient operation. The pressure gauge provides an accurate reading of the system pressure and is equipped with red markings for easy reading.

    Easy Installation and Use

    Termoventiler AS is easy to install and use. The collection pipe has internal threads G1 and G ¾ and the safety valve has an internal thread G 1¼ at the outlet. Connections for soft and hard copper pipes, thin-walled steel pipes, chromed copper pipes, and PEX pipes are made with compression couplings. A support sleeve is needed for soft copper pipes. The valve set is normally maintenance-free, but should be function-tested twice a year to ensure proper operation.

  • Laddomat 11-30 ErP


    The Laddomat 11 is a complete unit and is simple to install. It ensures perfect charging of the tank. Thanks to efficient hot water control, Laddomat 11 can have a higher opening temperature at high boiler output compared to other similar products.

  • Laddomat 21-60, R32, LM9A, 63°C Charging Unit


    Laddomat 21 allows the boiler to quickly reach 80°C working temperature. Then the Laddomat starts loading the tank with a high, even temperature. The most appreciated feature is the built-in automatic throttling of the internal flow. This throttling function ensures that the entire tank system is fully charged. After the fire has stopped, Laddomat 21 takes advantage of some of the after-heat in the boiler by transferring the hot water in the boiler with self-circulation to the tank. The energy ends up in the tank instead of in the chimney. Laddomat 21-60 is delivered as standard with EPP insulation and proper valves, R32, with lever. The extra large openings in the ball valves contribute to the good self-circulation.

    For boilers with a maximum power of 80 kW.

  • Mixing valve LK 550 AquaMix - External thread


    LK 550 AquaMix is a mixing valve for hot water preparation with a thermal insert that regulates the supply of cold water so that the desired temperature is reached. Desired hot water temperature, within the control range +38°C - +65°C, is set with the valve knob.

    • Dimension: G ¾
    • KVS M³/H: 2,2
    • Weight: 0,4
  • Outdoor sensor for ESBE CRB122


    With an outdoor sensor for your CRB221 temperature control, you get a combined outdoor temperature and indoor temperature based control. If there are rapid shifts in the outdoor temperature, then the shunt compensates for this to further stabilize the heat curve. The communication cable is 20m long.

    Fits all CRB221 (and CRB122 from 2016 onwards).

  • Shunt valve 4-way bivalent, CU22, KVS 6.0


    This 4-way bivalent shunt valve is made of brass and has a compression fitting for easy installation. The valve is part of Thermoventiler's TV 4BIV series and is specifically designed for controlling the heat in bivalent systems where two heat sources are used in parallel or in series. Additionally, the valve can function as a distribution valve for 3 different energy storage units to optimize the system.

    For example, you can use this valve to extract heat from two different levels in an accumulator tank or send heat to 3 different levels to utilize the cheapest energy source in the first place. The valve can be controlled by a valve and a control device. It has a pressure limit of PN10 and a Kvs of 6.0. The valve has a dimension of 22mm (DN20) and can operate within a temperature range of 0 to +130°C.

    With this valve, you get a simple and effective solution for controlling the heat in bivalent systems, while also having the ability to optimize your system and utilize the cheapest energy source in the first place.
