How it works

There are 3 parameters to be checked

1. Max. 30m of pipes (internal diameter 20mm) between boiler and shower.

   Verify by opening the hot water at 100%. If less than 10L of cold water comes out before it turns warm, you can enjoy the instant hot water technology. Not the case? Contact us for a tailored product.

2. The incoming hot water should have a temperature of at least 55°C. This is the minimal temperature according to regulation.

3. The operating pressure should be between 2 and 6 bar.

All parts are easily accessible and can be replaced in case of issues. We built a product to last.

As you wish!

Thanks to its high-performance insulation, the water temperature in the reservoir decreases by only 5°C every 24 hours.
This means you can still enjoy instant hot water for up to about 3 days after your last shower, without active heating.
Once the water temperature drops below 42°C, the heating element automatically switches on to reheat the water.

Enjoy!

During the first days, the water in the Therm-eau reservoir will slowly cool down (approx. 5°C per 24h). Once the water temperature drops below 42°C, the heating element switches on to ensure you can enjoy your instant hot water upon return!

Even though you can enjoy instant warm water without electricity during regular use, connecting the heating element to power (via an easy 12V adapter) gives you unlimited hot water anytime you need it.

Your safety is our top priority.
To ensure safe showering conditions, we conducted extensive testing in collaboration with certified research facilities.
In accordance with NEN1006 guidelines, a minimum hot water temperature of 55°C must be maintained.
Operating at lower temperatures may cause issues throughout the hot water system.

Yes, a boiler or a heatpump is required to heat the water. Heau stores energy from the previous shower session to start your new shower with instant hot water.

An industry standard 1/2″ thread connector with hot and cold water is required.

The water pressure should be between 2 and 6 bar. In most countries, this is the case in almost every household.
