Savings and sustainability for the hotel sector

Tourism and hospitality are two fundamental industries in the modern economy, but they are also recognized for their high energy consumption. In an effort to become more sustainable and environmentally friendly, hotels are looking for innovative ways to reduce their carbon footprint and lower their operating costs. One solution that is becoming more and more popular is the use of heat recuperators. These are responsible for generating sanitary hot water for free. How do they do that? Taking advantage of the heat energy produced by the heat pumps of the air conditioning systems.

What is a heat recovery?

A heat recovery device is a device that recovers and uses residual heat. This heat is generated in a process or system for use in another process. In the case of hotels, the residual heat comes from the heat pumps that are used for air conditioning. These heat pumps extract heat from the air to cool rooms, and as a result, they also generate heat that is normally dissipated outdoors. However, with a heat recovery, this waste heat is captured and used to heat domestic water.

Production of domestic hot water for free

Take advantage of the energy discarded by the refrigeration circuit to produce sanitary hot water totally free.

Heat recovery operation

The heat recovery system to generate domestic hot water is surprisingly simple and highly efficient. First of all, a heat exchange device is installed in the circuit of the heat pumps of the air conditioning system. This device captures the residual heat and transfers it to a heat exchanger that is connected to the hotel’s domestic hot water system.

As air conditioning heat pumps work to cool the indoor environment, the heat that is produced is collected by the heat exchanger and transferred to the water to be heated. It is a continuous process for as long as the heat pumps are running. This process manages to obtain domestic hot water practically free of charge.

Cost reduction

One of the main benefits of using a heat recovery unit is the significant reduction in water heating costs. By taking advantage of the waste heat from heat pumps, the hotel can drastically reduce its dependence on traditional energy sources to heat domestic water, which translates into significant savings on energy bills.

Sustainability and respect for the environment

By taking advantage of heat energy that is normally wasted, a kind of “heat recycling” is done. Hotels adopt this technology that reduces their carbon footprint and contributes to the conservation of the environment. By using less fossil fuels to heat water, the emission of greenhouse gases is reduced and the sustainability of the business is promoted.

Best corporate image

The adoption of sustainable technologies, such as heat recovery, can also improve the hotel’s corporate image. Customers are increasingly aware of the importance of environmental responsibility, and will choose a hotel that demonstrates its commitment to environmentally friendly practices.

The implementation of heat recovery units to generate domestic hot water from the residual heat from air conditioning heat pumps is an innovative and highly beneficial solution for hotels. This technology not only reduces operating costs and improves the sustainability of the business, but also positions the hotel as an actor committed to protecting the environment.

An ideal option for any hotel that wants to improve its energy efficiency and reduce its environmental impact. The use of heat recovery is an option that should not be overlooked. An investment that will not only generate long-term savings, but will also contribute to building a more sustainable future for tourism and hospitality.
