3 Simple Steps

Step 1. Verify

  • For an optimal experience, the distance between your boiler and shower should be limited. The maximal distance depends on the diameter of the pipes. The volume of the water in the pipes should be lower than 10 liters (= storage volume), for the Therm-eau technology to provide sufficient energy to provide instant hot water during the start.

    For typical pipes (Copper 22/1 or Alpex 25/2.5), the maximum distance is 30 m. For other types of pipes, please check the specific pipe table.

    A quick way to measure this volume of water in your hot water pipe is to open the tap at maximal temperature and measure the volume of cold water that comes out before the hot water. If you fill less than a full bucket of 10 liters, you’re good to go for this generation of Heau systems! If you fill more than 10 liters with cold water before the hot water kicks in, please can contact us for a custom solution.

  • For optimal performance of the Therm-eau technology, we recommend setting a minimum temperature of 55°C of the incoming hot water. Higher temperatures will further increase storage duration.

    Regulations and Guidelines

    • We emphasize maintaining a minimum hot water temperature of 55°C, in accordance with NEN1006. For lower temperatures, your hot water circuit is not according to regulations and can cause issues within the entire circuit.

    Temperature Stability

    • In a 20°C environment, the Therm-eau tank’s temperature decreases by approximately 5°C every 24 hours.

    • If hot water enters at 55°C and you finish your shower with storage around 55°C, the maximal starting shower temperature after 72 hours (3 days), will be around 40°C, which is still above 38°C (normal usage).

    Energy Storage

    • Higher incoming temperatures from the boiler allow for more energy to be stored. This results in longer maximal intervals between shower sessions. As an example, with hot water at 62°C a storage of 4 days is possible, while still providing a comfortable hot water temperature at the start of the shower. 75°C results in 5 days heat storage, and so on.

  • Each time you take a shower, the advanced Therm-eau technology is charging for the next session. To ensure the system is adequately recharged and ready for your next use, we recommend a minimum shower duration of 2 minutes. This allows the system to efficiently store sufficient energy for subsequent showers, maintaining consistent performance and comfort.
