CWDR type horizontal fully automatic electric hot water boiler

The fully automatic electric hot water boiler uses electricity as its energy source and uses electric heating tubes for heating. It has the characteristics of fast heating, high thermal efficiency, small size, and low noise. It can be combined and operated in parallel for heating and is easy to install and use. Suitable for heating and hot water, it can be paired with chiller units to form a central air conditioning system for both heating and cooling. When paired with a water storage tank, it can form a thermal storage electric boiler that utilizes electricity during peak and off peak hours at night to reduce operating costs.

Performance characteristics of CWDR electric hot water boiler:

The fully automatic electric hot water boiler uses electricity as its energy source and uses electric heating tubes for heating. It has the characteristics of fast heating, high thermal efficiency, small size, and low noise. It can be combined and operated in parallel for heating and is easy to install and use. Suitable for heating and hot water, it can be paired with chiller units to form a central air conditioning system for both heating and cooling. When paired with a water storage tank, it can form a thermal storage electric boiler that utilizes electricity during peak and off peak hours at night to reduce operating costs.

The CWDR series fully automatic hot water boiler adopts an intelligent digital boiler computer controller, which has boiler outlet water temperature control, four time period timed operation, boiler water replenishment control, outlet and return water temperature detection, secondary return water electric control valve control, etc. Fault detection includes complete protection functions such as water shortage protection, overtemperature protection, furnace shell overtemperature protection, pressure protection, etc., ensuring safe and stable operation of the boiler.

Feature Highlights:

1. One click start stop: an intelligent digital boiler controller that uses dynamic graphics to display the boiler's operating status, fully automatically adjusts the heating water outlet temperature and bath hot water temperature, loads and unloads the heating tube group step by step, balances the electrical load and protects the heating elements, extending their service life.

2. The working status is clear at a glance, with automatic control functions such as digital temperature display, temperature control, over temperature, and antifreeze protection. The water temperature can be set arbitrarily within the range of 5 ℃ -90 ℃, and the hot water pump or solenoid valve can be controlled to work automatically, providing heating to the heating system or hot water to users.

3. Adopting low surface heat load electric heating tubes, the outer sleeve is seamless stainless steel tube, and is connected to the furnace body with flanges for easy disassembly and maintenance. The heating element is electric heating wire filled with high-purity magnesium oxide powder, with a long service life; Reduce the adhesion of scale on the surface of electric heating tubes.

4. The boiler control cabinet and furnace body are designed in a separate manner to avoid heating of electrical components. The circuit design is advanced and well made, with neat and reasonable wiring. It has multiple protections such as short circuit, overload, leakage, phase loss, abnormal voltage, abnormal temperature sensor, abnormal water level sensor, secondary overheating, ultra-high water temperature, furnace shell overheating, and water shortage fault alarm.

5. Durable, clean and hygienic: The inner pot is treated with special materials, which not only protects the inner pot but also ensures the cleanliness and hygiene of the boiler water quality.

6. Using high-quality insulation materials to reduce the heat loss of the boiler itself, its conversion efficiency is about 95%.

7. The shell is made of high-quality sheet metal, which is not easily corroded and has a beautiful appearance.

8. The boiler is manufactured with a compact structure and easy installation. It can be put into operation by simply connecting water, electricity, and gas.
