INTERIOR STRUCTURE OF TANKLESS WATER HEATER GAS MODEL ET197
The venting system uses large venting duct with gas exhausted by DC stepless variable frequency and variable speed fan. The system features no solder joints, endurability and very low noise. The Fan stepless regulating works perfectly with combustion system, thus remarkably improves the efficiency by 10%.
Traditional fan has fixed rotating speed, generally 2800r/min. When pressure against exhaust venting duct approximates 120pa, the water heater can only power off to prevent possible damages from obstructed venting. That makes it a concern for water heaters installed in high rise buildings or windy environmen where high wind is commonly encountered. DC Stepless Variable Frequency and Variable SpeedFan, when senses wind resistance, will raise rotating speed to deal with wind drag so that the water heater can maintain proper operation. The rotating speed can raise up to 6000r/min, sufficient to cope with 10 levels of gale.

It is equipped with intelligent capacity ajustable function, adjustable from 13-10-8L. This offers outstanding performance in catering for different needs for DHW, but also makes the outlet hot water delivered at a more stable temperature at the same time. Cost-effectiveness is remarkable.
One of the outstanding features of 16ET266 is to deliver as much as 16L hot water at constant temperature. A big 7-key touch screen is a plus to its sleek design when making the heater status clear at a glance. It also has multiple functions of bathtub water filling mode, kitchen comforter and adjustable capacity.
13ET222 water instant heater features a winter/summer pattern and a large LED display with easy user interface.

16V 18 hot water heater features large capacity of 16L per minute at 25℃ rise. Besides, it comes with four-season mode. The heater can automatically set outlet water temperature according to temperature changes in different seasons.
Condensing gas instant water heater is a high efficient and environment-friendly hot water heater. It has double heat exchangers. In additional to the primary exchanger conventional heaters generally have, it has an extra condensing heat exchanger (or latent heat exchanger). When in operation, the high temperature smoke goes upward, from primary heat exchanger to the condensing heat exchanger, while water flow goes downward, first through condensing heat exchanger and then main exchanger. The cold water absorbs the residual heat in the condensing heat exchanger first and after that it takes in heat of the main exchanger. All these heat added up makes its efficiency much higher than regular water heater.
EK190 is our basic model. It is controlled by micro-computer and supplies endless hot water at constant temperature.
