Is Ecologically friendly. Economical, Simple, aesthetic, Effective and autonomous: • Ecologically friendly: With a Everhot 500E system, the emissions of C0 Avoided Annually are equivalent to the fuel emissions of a car having run for 10.000 km.
Page 5 The forced circulation system EVERHOT consists of Thank you for choosing to buy a solar system EVERHOT Bl1 or Bl2. Every system which you acquire consists of: 1. Boiler with one tube heat exchanger (type BL1) or with two tube heat exchangers (type BL2) on a wooden palette and wrapped with stretch film.
Page 6 General Information on needs of hot water General Information When choosing a solar system for hot water we must first determine our needs for hot water, in quantity as well as in preferred temperature of consumption. The typical calculation for the temperature for consumption is 45ºC, but for the calculation of required quantity you must take into account the daily needs.
Page 7 General Information on needs of hot water Example: An installation of agro tourism is maintained by a family of 4 persons that live in the residence. During the period between May and August the average occupancy is 15 clients per day. For the occupants 2 meals are prepared per day and the dishwasher washes 5 times per day.
Page 8: Forced Circulation Kit - Function
Forced circulation kit Function When the difference in temperature between the sensor located in the solar collectors and the sensor located in the storage tank is greater than the ‘Differential Temperature’, adjusted on the differential thermostat, the circulator of the closed circuit starts up. This is located in the hydraulic kit.

Page 22: Differential Thermostat
Differential Thermostat TCD1 Description The programmable electronic thermostat secures the smooth transfer of thermal energy from solar collectors to the boilers via an electronic command to the circulator of the solar system. Differential Temperature Controller for solar systems, type TDC-1 by SOREL-Germany. The controller is user friendly through its digital screen, the information given (sensor’s temperature, operation status etc.) and could easily adapt to many different types of application.
