Short Description of the Da Vinci Luxury Hotel Project

Kayema Energy Solutions completed a solar thermal hot water system with storage capacity of 10 000 litres for the Da Vinci Luxury Hotel and Suites at Nelson. The system incorporates an existing radiator as back up, and 117 solar collectors as the primary heat source. The Legacy group benefits from large savings daily.

Solar Thermal Hot Water System at Da Vinci Luxury Hotel Introduction

The STTP Work Group 3 has embarked on a program to film the “10 MOST AMAZING SOLAR THERMAL SYSTEMS IN SA”. The project is aimed at the following:

  • Growing the Solar Thermal market through industry awareness and collaboration
  • Establishing confidence in the market place with Engineers, Architects, designers and contractors by showcasing solar systems installed in SA
  • Creating a Social Media platform where these videos are available FREE for training, marketing and showcasing the SA capacity directly impacting market awareness and growth.

CAPACITY AND UNIQUE CHARACTERISTIC’S OF THE SOLAR HOT WATER SYSTEM

The installed system consists of 117 solar collectors, 10 000 litres of hot water storage, radiator heat recovery, an external heat exchanger, and a circulation loop spanning 17 floors! The uniqueness of the installation can be attributed to the relatively small roof space available for the collectors. A complex mounting structure was designed so that the collectors could be elevated to a level that allows walking space below it. In addition, the storage and heat exchangers are located at the basement of the hotel, which presented a challenge in terms of limiting heat losses.

Measurement and verification of the system performance was also included.
