About
The Blue is a shower system using WWHR technology. The Blue 21 includes a single WWHR pipe, frame, pump, sensor and a power supply.

When a shaft or technical room is near the bathroom it won’t be necessary to purchase the glass panel. The Blue can be installed here when the drainage and the cold and hot water supply are there as well. 

Another option is having the Blue built-in to the bathroom cavity wall. In this case the optional glass panel is required to function as a maintenance hatch. The glass panel comes with a thermostatic mixing valve.

The standard warranty period is 5 years for normal private use.* This can be extended to 8 years.

Shipment
The production time of the Blue is 8 – 10 weeks. The shipment will be as soon as possible after the production. Shipping costs depends on your location and are calculated during check out.
