AQUACIAT 2 HYBRID

Aquaciat 2 HYBRID is the first range of packaged, outdoor, reversible hybrid heat pumps that house an integrated natural-gas-powered condensation boiler module. This new range combines the benefits of both technologies in a single package that is compact and particularly easy to install. With a total of eight possible combinations available and three 45 to 80 kW boilers, Aquaciat 2 HYBRID meets the heating and air-conditioning needs of new and existing tertiary-sector buildings ranging from 500 m2 to 1500 m2. Engineered using eco-design principles, the entire range is at least 85% recyclable. Aquaciat 2 HYBRID won the Silver Trophy in the HVAC category at the Innovation Awards held during the Interclima trade show in Paris from 4th to 8th November.

Aquaciat 2 HYBRID heat pumps are particularly compact and easy to operate. Their all-outdoor design means that they are simple to install, do not require the building to be equipped with a machine room or a gas boiler room or gas-fired boiler rooms, and do not entail extensive alterations. A small outdoor space and a connection to a natural-gas supply are all that are needed.

Aquaciat 2 HYBRID heat pumps provide heat either thermodynamically or with their gas-fired boiler depending on the scenario chosen by the system user. Aquaciat 2 HYBRID controls the automatic operation of the system all year round. An outdoor temperature sensor enables the CONNECT2 controller to switch between cooling and heating modes. In heating mode, it ensures that the heat pump's minimum COP remains higher than the primary energy conversion factor for electricity (2.58 in France) and automatically switches between gas or electricity, depending on which is the most economical source of energy.

Aquaciat 2 HYBRID ensures efficient use of electricity. It can automatically switch over to the gas-fired boiler when the electrical power reaches a threshold value or upon receiving an external signal from a BMS. The advantage for smart grids is that it can supply exactly the same heat output regardless of the energy source (gas or electricity). It also instantaneously lowers the electricity usage during wintertime peak-load periods without compromising on comfort for users.

Aquaciat 2 HYBRID is also particularly well-adapted to harsh winters. Unlike a basic air-to-water heat pump, it can deliver a maximum amount of heat during extremely cold weather. Because the capacity of the gas-fired boiler is independent of the outdoor temperature, indoor environments remain comfortable and peak heating needs are met in full. The '4-pipe/DHW' option also allows hotel owners to use the gas-fired boiler to provide high-temperature domestic hot water whilst continuing to heat economically with the air-to-water heat pump.

Aquaciat 2 HYBRID is designed to make life easier for installers. Its compact housing contains a 'standard' heat pump and a condensing boiler with a single hydraulic connection point for easy outdoor installation on small decks or patios. Aquaciat 2 HYBRID also comes equipped as standard with a system pump and an expansion vessel for simple water-expansion calculation and easy connection to the indoor circuits of existing systems. The simplicity of its central hot-water circuit makes installation by any heating specialist or installer easy and accessible, even in the case of complicated projects.

Aquaciat 2 HYBRID is particularly well suited to urban environments. Whatever the heating and cooling needs, it does not cause any noise pollution, either indoors or outdoors. In night mode programmed with gas heating, only the low noise of the boiler is perceptible, thus avoiding night-time acoustic discomfort for both the users inside the building and residents outside.
