Household gas-fired wall-hung boilers can be heated independently without heating at the same time as central heating. Home heating is more convenient and arbitrary, and the time and temperature can be controlled by yourself. When choosing, we mainly pay attention to quality, brand, after-sales service and cost performance. No matter how good the brand is, it will be divided into high, middle and low grades. Therefore, cost performance is very important, and after-sales service quality assurance is also the key. Otherwise, the later maintenance of the wall-hung boiler will make you very troublesome!
