    magnetic equipment for heating water to VDI 2035

    A heating water treatment unit is a device that prepares the filling water or regulates the circuit water to prevent lime, corrosion and sludge. Q-Tech brings together here the range from magnetic (Germany) for topping up with demineralised water and protecting the system in operation. For all units, ask for a quote.

    How to choose

    • Filling water: the NF plus for frequent top-ups; the cartridge 300 for the first fill and occasional top-ups.
    • Circuit water: the HWR regulator by system water content, calculated as output in kW times 20, according to magnetic.
    • Type of system: the HWR compact plus for diffusion-tight circuits only; with plastic pipe without a barrier, the HWR plus.
    • Other brand: compare magnetic with ROTHENBERGER in VDI 2035 water quality.

    Applications

    • Heat pumps with buffer tank and underfloor heating.
    • Boilers and building plant rooms.
    • Refurbishment of systems with sludge and corrosion.

    Why choose Q-Tech?

    1. We integrate water treatment into the pre-assembled plant room, tested in our workshop.
    2. We connect and set up the unit with the on-site Expert Technician.
    3. We explain the guideline in our article VDI 2035: water quality in heat pumps and heating systems.

    Frequently asked questions

    What is the price?

    Ask for a quote: message us on WhatsApp with the model and we will send it to you.

    What do I need, filling or regulating?

    It depends on the condition of the water: we recommend a laboratory analysis of the circuit water before deciding. Usually you need demineralised water for filling and a regulator if oxygen gets in, for example with plastic-pipe underfloor heating.
