Alterra WZSV

AMBIENT LOOP

The Alterra WZSV is a compact brine/water source heat station intended for use within district heat networks where an ambient loop is the source of energy or for standalone properties where energy is sourced from a series of geothermal probes or ground collectors. Heating and comfort cooling can be provided with the WZSV, and the integrated 180 litre storage cylinder will give copious amounts of domestic hot water for the whole family.

Compact dimensions

Despite the many integrated components, the dimensions of the Alterra WZSV are very frugal, and the unit takes up less than half a square meter of floorspace, making the WZSV ideal where space is at a premium, such as within city apartment buildings.

Easy controls

The Alterra WZSV is equipped with an integrated/wall-mounted user interface. The unit is also manageable remotely via a smartphone app.
