ZEWO Loft «PREMIUM»

The proven product series ZEWO Loft >>PREMIUM<< is specially designed for the upscale residential construction. The modular system includes prefabricated installation packages, which allow flexible adaptation to every need in the housing industry.

Depending on the model, the PREMIUM version includes the innovative CTR control system, which makes hot water and heat supply even more individual and comfortable while at the same time providing precise consumption control. Maximum energy savings are achieved through state-of-the-art control components, including ZEWO SmileTech, which independently regulates the hydraulic balance.

The home stations are available as basic modules in four versions, and with the equipment they contain they are ready for use as home stations for transferring heat from local or district heating networks to the heating and drinking water systems in the residential buildings. The units are made of stainless steel tubing and mounted on a base plate, which are then delivered in an attractively designed, coated cabinet (surface-mounted or flush-mounted housing) ready for installation. The installation of the stations is easy on site and can be done in a few minutes and the pipes can be connected.

In addition to the following base stations, optional equipment is offered, which can be selected individually according to requirements and construction projects. For the complete range, please refer to the current sales documents in the Download area or on request.

Advice

The heat exchangers in the ZEWO Loft home stations are manufactured as standard with copper brazed stainless steel plate heat exchangers. Before using these heat exchangers, the technical building services planner or the installation company to be carried out must check within the framework of system planning whether the questions of corrosion protection and stone formation have been sufficiently taken into account in accordance with DIN 1988-7.4.1 and the available drinking water analyses. These include the selection of materials, the consideration of corrosion-related changes in the quality of drinking water, the design of the installation and the consideration of expected operating conditions. We recommend that you provide us with a current drinking water analysis in advance of the construction measure in order to test the material to be used. We will be happy to help you with any questions you may have.
