Heat Pump Network HC Solar Energy Water heater as Environmental protection Energy Security and many other advantages, the concern by many consumers, but relatively speaking not very popular solar water heater, solar water heaters, consumers worried about whether it is durable, and damage to the news on the solar water heater is endless, then the solar water heater do so " fragile "it? In fact, solar water heater manufacturers have said that life for 15 years or so of this, consumers should have a clear understanding. Solar water heater caused by "short-lived" reasons. A vacuum tube. Vacuum tube solar water heater core components, solar water heater is the "heart." It directly determines the quality of the entire platform water heater performance. The use of vacuum coating technology and the performance by cleaning, coating, vacuum, sealing and other process effects. However, some ultra-cheap solar water heater vacuum tube used has the following shortcomings: the vacuum is low, only the quality of the 1 / 100; tube left a lot of impurities and water vapor, a face becomes hot gas, the vacuum was reduced; low vacuum film stability under poor intimal layer on two or three years of aging, loss, leading to rapid decay collector performance, can not absorb enough heat. II insulation. Solar water heaters produce hot water during the day is stored in a storage box, if the thermal insulation performance is not good, overnight, rainy days can not be used, or not work. Solar water heater caused mainly due to poor insulation performance water heater insulation, insulation of hot water temperature, good or bad determines the level and amount of how much hot water. Good insulation of imported raw materials, such as polyurethane, low thermal conductivity, high temperature; insulation process is fully automatic quantitative foaming temperature high pressure and high temperature aging treatment, heat stability and high performance and durable. Some inferior materials, high thermal conductivity, foam is not uniform, the night temperature can drop more than ten degrees, rainy days, no hot water experience. There's black heart business, in order to reduce costs, even with home-made polystyrene board, after months of plummeting insulating effect, in 2012, are basically no insulation. Three liner. Currently, most solar water heater manufacturers have said the water container is stainless steel. Similarly, stainless steel, but stainless steel and nickel-chromium are very different. Good solar water heater with high chromium high nickel stainless steel liner, liner ensures durability, corrosion resistance strong; poor more than low grade stainless steel liner, the basic non-nickel, corrosion performance is poor, short life. 4, installation and service. Solar water heater on the installation requirements are very high, professional installation is the basis of its easy to use and security of the winter. Some no-name companies around the recruitment of migrant workers often form a "guerrilla", no formal training in a hurry posts, these people either do not understand the design of piping, water heaters, fixing the main body of professional knowledge, but also do not understand a post of maintenance, resulting in problems abound, the direct impact of solar water heaters "standards life." For example, for a fixed water heater accessory mounting bracket, big brands use more steel section, strong, corrosion resistance, however, some small manufacturers are using wire fixation, resulting in some areas, an experienced heavy rain, hail and other inclement weather, there is no small solar water heater knockout. Solar water heaters should be noted in the course of which issues? 1, note the time in Sheung Shui. 2, according to weather conditions, the decision on the amount of water to ensure proper water temperature when bathing. 3, regular check water heater pipes, vent and other components are working correctly. 4, air pollution is serious, or sand, dry, flushing tube area on a regular basis. 5, water heater installed, non-professionals do not easily move, loading and unloading machine, so as to avoid damage to critical components.
