As the weather gets colder, the water heater market also presents a pleasant scene. In terms of the current market, there are two types of water heaters, namely gas water heater and electric water heater. These two kinds of water heaters have their own advantages and disadvantages, and how much do you know?

Gas water heater

Gas water heaters include positive displacement type and fast type. The common type is fast gas water heater. Fast gas water heaters are divided into direct discharge type, flue type, forced discharge type and balanced gas water heaters. Among them, direct discharge water heaters are easy to cause personal injury accidents and have been banned from production.

Advantages: fast heating, large water output, stable temperature, less scale, small land occupation and no water control.

Disadvantages: toxic gas will be discharged due to insufficient combustion during use, or gas pipeline explosion, gas bottle explosion, etc., resulting in safety accidents; High starting water pressure makes it impossible for high-rise residents to start without booster pump; If the installation is inconvenient, holes shall be made in the wall and air fans shall be arranged; Different gas has different burner shape, nozzle size and cross-sectional area of gas channel.

Commercial water heater

Commercial water heaters are divided into instant electric water heaters, pre instant electric water heaters and water storage electric water heaters. Instant electric water heaters and water storage electric water heaters are commonly used. The pre instant electric water heater is facing elimination as soon as it is on the market because of its great potential safety hazards and poor use effect.

Advantages: the instant electric water heater has the advantages of fast heating, small volume and high energy efficiency. The water storage electric water heater can adapt to any weather change. Ordinary families can directly install and use it, and large flow of heating water can be supplied after long-time power on. In addition, the installation is simple and not restricted by gas resources.

Disadvantages: the power and current of the instantaneous electric water heater are relatively large, the line requirements are high, the installation requirements are also high, and the water and electricity are not separated, so there are hidden dangers of power safety. The water storage electric water heater has a huge volume, occupies a large indoor space, is easy to scale, wastes a lot of electric energy, and there will be hidden dangers of electric leakage due to the aging of the line. The latest electric water heater has built-in anode magnesium rod descaling device, which solves the problem that the product is easy to scale. However, the anode magnesium rod must be replaced once every two years, which brings trouble to the maintenance. http://www.swncq.com/
