Traditional solar water heater system functions on the basic physics phenomena indicating that hot water has lower specific gravity and therefore floats on top of the cold water, forcing to install the hot water reservoir/boiler higher than the solar panel that absorbs the solar energy to heat the water. The entire cold water content is to circulate slowly (in closed circuit) through the water reservoir until the entire water content heats up. The process takes about two hours per 10 degrees of temperature increase in a hot and sunny day.
The Hot-Control ™ smart system utilizes a small, electric pump combined with an advanced control scheme to optimize system performance with the following excellent results:
Special Temperature sensor is installed in the water reservoir, monitoring the water temperature. Hot-Control ™ controller is activating a small electrical water pump accordingly to transfer already hot water from the solar panel into the reservoir, avoiding the transfer of cold water into it! Additionally, system integrity is continuously monitored.
Normal Controlled range is 28 to 96 degrees centigrade. Extended working range of 20 to 150 allows emergency programs activation in case of malfunction.
Easy and simple installation by solar water heater installation technician. No special skills are required. The technician has at his disposal three maintenance programs to assist him in installation and troubleshooting. Everyday operation is absolutely automatic.
Various System Configurations
1. Basic Hot-Control ™ system with one solar panel and one hot water reservoir.
2. Multi Hot-Control ™ system for a cluster of solar panels.
3. Split Hot-Control ™ system with Master / Slave configuration. Master unit located close to Solar Panel/s and the slave units close to each hot water reservoir supervising on hot water intake needed for each reservoir (additionally eliminates the need for an expensive internal heat exchanger).
Versatile system intended for broad heating system configurations, from basic systems with only one solar panel and one reservoir up to a solar panel cluster capable of high capacity heating including heated swimming pools.
The innovative Hot-Control ™ approach was developed three years ago and implemented in new and advanced electronic control circuits. Satisfied customer base of more than 3500 installations approves day after day the necessity of Hot-Control ™ system to a truly successful solar water heating system. The flexibility of the system and its computerized control makes it an ideal solution for extremely cold or extremely hot climatic conditions. System parameters can be customized and fine tuned for specific design requirements.
