In the past, because of fast heating and low cost, the field of commercial hot water has always been the world of coal-fired boilers. But in recent years, as the country attaches importance to environmental protection, a large number of coal-fired boilers have been banned, and more and more environmentally friendly and clean heating equipment have entered the commercial hot water market. At present, the commercial hot water market mainly includes gas boilers, electric boilers, solar water heaters, and air energy heat pumps.
So, what are the effects of these four types of hot water equipment and what are the advantages and disadvantages?
Gas boiler: Gas boiler has low purchase cost and fast heating speed, but it has certain safety risks and requires special boiler room and manual maintenance. The most important thing is that many country is gas-poor , so the price of natural gas is relatively high, and in winter, it is easy for the equipment to fail to work due to insufficient natural gas supply.
Electric boilers: Electric boilers are environmentally friendly, clean, and clean when used, but because they use "electricity-heat" direct conversion, the use of electric boilers not only has potential safety hazards, but also has very high heating costs.
Solar water heater: As a new energy equipment, safety, environmental protection and power saving are the biggest advantages of solar water heaters. However, the shortcomings of solar water heaters are also very obvious, that is, "seeing the sky and eating" are serious, and they cannot work in winter, rainy days, and at night. They cannot supply hot water 24 hours a day. They need electric auxiliary, but the price of electric auxiliary is high. At the same time, solar water heaters occupies a relatively large area when installed, and need to be installed on the roof of the top floor. There are potential safety hazards such as wind blowing or lightning damage.
Air energy heat pump: Like solar water heaters, they are all new energy equipment, and they also have the advantages of safety, environmental protection, and power saving. The only difference is that solar water heaters use solar energy, while air energy heat pumps use air energy . Therefore, air energy heat pumps are not as serious as solar water heaters. Regardless of the north and south, winter and summer, sunny and rainy days, air energy heat pumps can be used normally without electric auxiliary, providing stable hot water for buildings 24 hours a day. . In addition, the air energy heat pump has a very small footprint when installed, does not require a boiler room, does not need to be installed in a designated place, and does not require manual monitoring during work, which can save management costs.
