How about a gas wall-hung boiler for hotel decoration?

Generally, gas-fired wall-hung boilers can provide heating and domestic hot water, so this problem should be explained from two aspects: in terms of heating, the operating cost of using wall-hung boilers is 35% cheaper than that of using air conditioners, and heating is not dry with air conditioners; In terms of domestic water, the thermal efficiency of ordinary water heaters is only 75%-85%, while the thermal efficiency of gas-fired wall-hung boilers is as high as 90%, and some are even higher. For example, the thermal efficiency of Marui wall-hung boilers is 92%. Therefore, it is more energy-saving than ordinary water heaters and can provide hot water for multiple bathrooms. Therefore, relatively speaking, gas-fired wall-hung boilers can be said to be relatively low-carbon and energy-saving.
