The Alterra WZSV from Modutherm 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.

Despite the many integrated components, the dimensions of the Alterra WZSV are very frugal, and the unit takes up only half a square meter of floor space, making the WZSV ideal where space is at a premium, such as within city apartment buildings. The attractive and modern appearance means the unit will not look out of place sited in a kitchen or other living area should a utility cupboard not be available. The WZSV can also be sited within a niche or even under a staircase as all access to the internal parts is made from the front of the appliance.

The Alterra WZSV provides the perfect solution for achieving high output within limited space constraints. In addition, the inverter drive modulating variants optimally adapt output to match that of the property, and its occupants, thus making them particularly energy efficient, which saves on electricity costs and makes them kinder to the environment.
