Water heater is essential for every household appliances, household water is the main carrier of the 19th century first water heater was introduced in Germany, after hundreds of years of development, and now the water heater has long been into the tens of thousands of households. Different, in fact, not many species. So what are the types of water heaters it? What are their advantages and disadvantages? Today to tell you about the types of water heaters and their advantages and disadvantages, hoping to help your life .
Mainstream products, can be installed in the bathroom, but must be hung on the load-bearing wall.Electric heating is the biggest problem of electricity expensive, especially in many cities have implemented a gradient electricity price.At present, the electric water heater has been completely hydropower separation, no need to worry about electric shock The problem.
Although the tank will be filled with cold water when bathing, most brands are currently able to achieve a very low temperature fluctuations. Some mid- to high-end electric water heaters have added the function of 'quick heat'. In summer, water can be increased or not stored according to the temperature of tap water Water restrictions, be regarded as a solution to some of the shortcomings of water storage water heater, and now if it can not be guaranteed constant temperature, the basic do not have to do a water heater.
Solar energy
Solar water heaters are usually only installed on the roof, so only the top recommended installation, other floors because the water pipe is too long, wasting water is also a waste of heat. Solar energy saving effect is very obvious, sufficient illumination in the area can reduce electricity, summer water temperature can even be achieved 99 ℃, only heat and poor weather need electricity to help heat.
However, in the south where winter sunshine is insufficient, there is no use of solar energy. The hot season is most likely to be without the sun.
Air to water heaters and air conditioning works almost the same, but also an outdoor unit to absorb heat in the air heating the water tank, but also to provide additional air-conditioning kitchen, very power, power consumption is 1/3 of electric water heaters ~ 1 / 4. However, the capacity of air to water heaters are mostly 150L +, large size can only be placed on the balcony itself is expensive and domestic 150L also 5000 yuan, only when the huge amount of water to reflect its energy-saving advantages. However , Because it absorbs the heat in the air to heat the water. When the temperature is too low, it can only be electrically heated.
So big a tank, throwing which are particularly obstruction children, the roof is a good choice that is the main hot water heater.
Gas water heater
Gas water heater covers an area of ?? small, that is, that is, and now the gas water heater has been solved after a short period of ignition water temperature is too hot hot problem. Condensing gas water heater recovers the heat of the exhaust gas preheating the cold water, heating Energy-saving effect is better.Most of the district are through the pipeline gas, as long as the water and electricity gas, hot water will not break.Gas thermal efficiency is relatively high, with gas itself is not expensive, so use a lot cheaper than the electric water heater .
The current mainstream of gas water heater exhaust strong row, but also joined a lot of protection measures, but must not be installed in the bathroom must be installed in a well-ventilated living balcony may be far from the bathroom kitchen to the winter will be closed doors and windows, This is not a good choice from a safety point of view or from a combustion efficiency point of view, unless ventilation is maintained when using a water heater. A balanced water heater does not have this problem because of the extra intake and exhaust lines.
All water heaters, the smallest and the lowest price, but the high power 6 ~ 8kW must use the green.Part of 6 ~ 7kW products can barely cope with the winter bath in the South, but the temperature and water pressure is low, more than 8kW in the north is sufficient There are some 9 ~ 12kW ultra-high-power electric water heater, also need to match the 60A meter, 50A meter on the need to apply for power company transformation.
Although the security is guaranteed, the power consumption is no higher than the water storage type (high power but short time), but the high cost of hydropower transformation is not universal reason.Now the instant electric water heater is still used in the kitchen more, That is, the instant hot pot treasure, a hot tap with hot water, water temperature and water pressure is not as high as the shower.
Wire can be concealed, I feel ugly can be hidden together with the cabinet.
Below to share several common and dangerous gas water heater exhaust method:
1, natural smoke flue-type water heater flue cover only set on the water heater, and then level out of the outdoor, even to the outdoor part of the drooping, case of wind will cause flue gas intrusion.
2, with the public ventilation of houses exhaust smoke, flue gas will enter the neighboring home harm.
3, flue and toilet exhaust pipe common outlet, then easily into the bathroom flue gas poisoning.
4, the flue and exhaust hood exhaust pipe common outlet pipe.
5, there is a leak on the flue, such accidents have repeatedly caused casualties.
6, flue crossing the bedroom, bathroom, flue leakage once the great harm.
Understand the heating principle and advantages and disadvantages of various water heaters, you can do an objective horizontal comparison among various categories, combined with their own family's actual needs and installation conditions, targeted to buy it. Although after the looks very simple, as long as the preferences, the price can be, they bought.
