State gas water heaters heat water in one of two ways. They can either burn natural gas or LP (liquid propane). All models allow the user to set a desired temperature for their water. When hot water is needed, cold water enters the tank through an internal "dip tube," which allows it to enter the bottom of the tank, trigger the thermostat and open the main gas valve. As it heats, the water rises to the top to exit the tank through a hot water supply line. A pilot light also aids the process for standard gas models. When the thermostat reaches a temperature where reheating is required, the pilot light ignites gas that has flowed to the burner (

Sepehr Electric high pressure updraft evaporative coolers (also referred as upflow). The air cycle operation of this device is to pulling the air from outside the cooler. Once the air is cooled inside the cooler, it is sent upward by the blower, creating an updraft of air. This air flows into ducts that spreads the cool air through the house. The perfect place to install this unit is either on trusses or balconies, you can certainly install and perfectly use them on the roof too.

Sepehr Electric high pressure side draft evaporative coolers (also referred as side flow). The air cycle operation of this device is to pulling the air from outside the cooler. Once the air is cooled inside the cooler, it is sent sideward by the blower, creating an side draft of air. This air flows into ducts that spreads the cool air through the house. The perfect place to install this unit is on the roof but could certainly be installed and perfectly used also on trusses or balconies.

Cellulose water coolers share almost similar air cooling qualities like the Aspen pad coolers. What makes them different from each other is the kind of evaporation interface. In cellulose water cooling systems, compact cellulose pads are used instead of aspen pads. Cellulose pads are made of cellulose paper sheets which are very thin, with high capillary and absorption capability. These pads are regular and wavy in form, have some certain grooves, special groove angels and function with water up to temperature of º. It is recommended to maintain the pH level of the water between and .

All Sepehr Electric vented gas heaters are equipped to three different safety systems: ) environment oxygen control system (Oxypilot ODS), this fully stops the gas flow upon oxygen lowering in the room to less than normal limit. ) Thermocouple, the thermocouple automatically shuts off the gas flow if the flame of the heater is turned off accidentally. ) Pressure governor, the governor will permanently regulate the input gas pressure in order to control and stabilize the output pressure in a safe and certain range.
