The number of hammams in Morocco was about 15,000 in 2018, ranging from traditional to luxury and SPA [4]. Most of them consumed large amounts of water and wood-energy. This resulted in significant environmental damage.

We recall that a study conducted in the town of Dar Bouazza in Morocco has led to define six types of hammams according to their buildings [1]. Each of them could, depending on the capabilities of their owners, make improvements to achieve gains in wood-energy. In addition to the use of improved boilers, a focus was made on the insulation of the walls and the Chebka, the use of heat exchangers and solar collectors.

In this article, we are, particularly, interested in the hammam Moulay Yacoub with which AARDD (Association of Applied Research Development Durable) has signed an agreement. This study allowed us to estimate the heat losses of this hammam on the basis of a study carried out from 27 January to 02 February 2020. The proposals for improvement are given here, particularly, by using a coil heat exchanger that was designed and manufactured from old solar water heaters. This allows to preheat the cold sanitary water from the warm water rejected by the clients of the hammam. The insulation of the walls of the hot rooms and of the hot water pipes, the use of both the exchangers we designed and the solar collectors could, thus, allow a saving of more than 1000kWh/day for this hammam.
