Last May we installed an important solar heating system for hot water in Lewa Wilderness Lodge.
Lewa Wilderness have 12 rooms for guests, 1 main house, laundry and 2 other room with bathroom.
The request of the owner has been to install the solar system in not visible position by customers.
We have decided to create three loops of pipes in order to serve three different areas of the Lodge, also two sub loop were realized.
The solar power system consists of a solar roof of 25 modules from 2.5 square meters completely waterproof.
Under this roof are installed different equipment needed to operate the system.
It is a forced circulation system where two return groups through a circulator, commanded by the central controller, move the solar fluid transfer of heat energy from the solar modules to heat exchangers.
These heat exchangers transfer the heat energy in a 3000 liter tank of technical water.
Another device provides through other exchangers instantly heat the service water.
Three circulators are concerned with moving water in the three loop and heat the line of over 1600 meters in length, so when we open the tap the water come immediately.
A wood incinerator is used as system backup.
The whole system is regulated by a controller which through a series of temperature and pressure sensors and the system automatically adjusts.
If the temperature difference between the solar modules and the storage tank exceeds 6 degrees the system turn on.
Two circulators, one for the East field and one for the West field, transferring thermal energy stored in the modules.
The controller adjusts the speed of the two circulators to obtain the maximum output temperature.
The system is connected by wifi to the Lodge network to remotely control any operating parameter and allow the maintenance and adjustment without being on the spot.
We are specialized in big solar central heating system for Villa, Lodge, Hotel, Hospital or solar heating district
