Maximize your comfort

Our goal is to maximize your comfort, while you use renewable energies. Following this philosophy, we have equipped our 120L PV-Boiler with two heating rods. The heating rods use the electricity directly from the pv modules. 
The use of two heating rods (NEX-R2x120 and NEX-R2) enables two-zone heating of your tank in layers. The application of heating zones allows us to provide maximum comfort for the user with minimum grid power consumption.

How it works

Upper zone 

At first, the upper zone of the storage tank near the hot water outlet is heated to 60°C. This enables faster hot water withdrawal. PV is prioritized as an operating source.

In the case of low solar radiation, the intelligent system reheats the upper zone of the water by using grid power. Thus, as little grid power as possible is used to keep your comfort level high.

Lower zone

As soon as the upper zone has reached its target temperature, the system switches to the lower heating rod and starts to heat the entire storage tank. The energy generated by the PV panel is stored in the water.

What We Offer

Our photovoltaic water heaters give you the chance to use your own solar electricity! Whether they use heating rods or a heat pump. They are designed as plug and play solutions and are therefore easy to install.

NEX P40

A photovoltaic heat pump water heater that reduces the electricity needed to heat water by 50%. It is our first product and produces the maximum amount of hot water from a single photovoltaic panel. 
A new version with more heating power and 50L volume will be available at the end of the year.
