The importance of hot water in a hotel

It is well known that one of the main energy demands in a hotel-type installation is the need to cover the domestic hot water (DHW) service expected by the clients of such establishments. This service is moreover a priority as its lack of availability could impair the image of the hotel as well as result in a possible loss of clients. To avoid this situation, hotels have historically resorted to the design of installations with large tanks of storage water in order to have a volume of water readily available that is able to cover times of peak consumption as and when they occur. This design criteria is sufficient to guarantee the right level of comfort and customer service, but can raise questions today in terms of energy saving and the financial costs of the equipment and installation.

Most thermal installations undertaken today in the hotel sector fall within the scope of refurbishment (such investments are often justified and supported by arguments on saving and energy efficiency. In some refurbishments, the boiler rooms are small and/or are hard to access, a fact that hinders the replacement of old units with new ones. It is in this circumstance in which the use of stand-alone units for outdoor use can offer the optimal solution.


Outdoor stand-alone solutions for heat generation are ideal for those types of projects where the installation of a conventional boiler room is impossible. This might happen when converting a room in which the installation of gas boilers is prohibited under current regulation UNE 60601:2013 or in a new building, to make use of the structure planned for chiller machines, thereby maximising the constructed surface area of the building (the space freed-up by the boiler room could be used for other commercial purposes).
