Which is good for electromagnetic water heater and air?
(two) electric water heater;1, the current domestic electric water heater is mainly water storage water heater. Divided into closed and open type of two. The water storage electric water heater is clean and sanitary, and does not need to be installed in a compartment, and no harmful gas can be produced, and the temperature can be conveniently adjusted. The inner chamber of the open water heater is not pressure resistant and can not supply multiple water at the same time; the inner of the enclosed electric water heater is able to withstand pressure and can supply multiple water supplies at the same time.2, advantages: can adapt to any weather changes, ordinary families can be directly installed and used, long time electricity can be large flow of heating water. At present, most electric water heaters sold on the market have anti electric shock devices.3. Disadvantages: bulky, large indoor space, easy to scale, waste of electricity. The new type of electric water heater is equipped with an anode magnesium rod descaling device, which solves the problem of easy scaling. But the anode magnesium bar has to be replaced two years, which brings trouble to maintenance.
2 advantages: fast heating, large water output, temperature stability, small scale, and small footprint, without water control.3 disadvantages: in the use process due to incomplete combustion and discharge of toxic gases, causing accidents; starting pressure is high, some live top users, such as the installation of booster pump will not start; the installation is not convenient, to a hole in the wall, exhaust fan; different gas burner nozzle, its shape the size and gas passage area are not the same.
(2) flue type water heater: the exhaust gas pipe is installed on the base of the straight row type. The oxygen needed for combustion is taken from the room, and the smoke generated by burning is discharged to the outside through the flue. When installing the water heater, the flue must be installed. When using, pay attention to the smooth exhaust of the flue and prevent the flow from flowing backward. Strong emission type water heater based on flue type adds an exhaust motor through the flue to discharge the waste gas, running, flue gas is forced to discharge through the smoke, but the oxygen needed for combustion is still from the interior.(3) balance type water heater is realized: three before a great leap forward, the shell is sealed, the flue and shell into one made of two layers of inner and outer flue, from the wall to the outside to the water heater operation when the oxygen from the outside through the outer layer of the air flue gas supply, combustion generated from the inner flue is discharged to the outside, so it is not on the indoor air consumption, no pollution. But installing such a heater needs to be as reserved as an air conditioner.
The advantages and disadvantages of four kinds of water heaters are introduced(1) gas water heater;1. The energy used by the gas water heater is combustible gas. It is divided into straight line type, flue type, strong platoon type and balanced type according to its form.(1) straight water heater: the oxygen needed when burning is taken from the room, and the smoke produced after burning is also discharged indoors. Disabled persons are prohibited from producing because they are prone to personal injury accidents.
