Domusa FUSION TRIO 180/80 Heat Pump Module: Integrated 80L Buffer Tank & 180L DHW Tank

Domusa FUSION TRIO 180/80 Heat Pump Module: Integrated 80L Buffer Tank & 180L DHW Tank

The Domusa Fusion TRIO 180/80 is an "all-in-one" hydraulic module (indoor unit) designed by the Spanish manufacturer Domusa Teknik. It is intended for installation alongside an air-to-water heat pump (such as the Dual Clima range). This module manages heating, cooling, and domestic hot water (DHW) production within a single unit.

180-Liter Domestic Hot Water (DHW) Tank: The hot water tank is made of stainless steel. This material ensures excellent thermal conductivity for rapid heating, as well as maximum resistance to corrosion and limescale buildup. It features an oversized coil optimized for air-source heat pump operation. Integrated 80-Liter Buffer Tank: This primary storage volume (or low-loss header) is crucial for the heat pump's proper operation. It prevents short-cycling (frequent compressor starts and stops), thereby protecting the equipment, extending its lifespan, and reducing electricity consumption.

Reversible System: The module is designed to handle both winter heating and summer cooling (via underfloor heating/cooling systems or fan coils). Comprehensive Equipment (Plug & Play): To simplify professional installation, the chassis comes factory-fitted with essential hydraulic components: an expansion vessel, a 3-way diverter valve (heating/DHW), air vents, and safety valves.
