Consider from the safety
Compared to the usual household appliances, gas water heaters are particularly important safety issues. Gas water heaters on the market now are usually divided into three main categories according to the smoke exhaust: flue, forced exhaust and balanced. Flue gas water heaters state has prevented manufacturers from producing, facing engraving. Forced exhaust type than the flue type safety factor is higher, the price is also a little more expensive. If your house is an elevator apartment, the state explicitly requires the installation of forced exhaust type. If you want to install the water heater in the bathroom, then you can only choose the balanced type, it is a kind of forced exhaust, exceptionally safe, but also the only kind of state regulations can be installed in the bathroom gas water heater. Flue type although there is a flue pipe to the outdoors, but there is no fan can only rely on natural exhaust, encounter high winds and other circumstances exhaust gas can not be dumped outdoors or even backflow, it is also easy to occur dangerous. The strong exhaust type is installed with a strong fan, even in windy weather can be useful to dump the exhaust gas outside. The balanced type is sealed with high efficiency combustion technology, allowing the gas to burn in a sealed space.
Consider from the brand
As a rule, the products of the best brands tend to reassure consumers to use, from the safety issue, we have to choose a trustworthy gas water heater brand.
Consider from the after-sales service
After-sales quality of the product, we ordinary consumers to pay special attention to. The above-mentioned seven brand-name products have a comprehensive after-sales service system. The usual warranty period ranging from 1 to 3 years, after the warranty period can also provide lifelong home maintenance, only the cost of fees.
Consider the individual needs of gas water heaters from the water output can be divided into 5.5 liters, 8 liters, 10 liters, 14 liters, 16 liters and other different models. To prove the difference in family water consumption to choose the rest of the model. Usually a bathroom bath with 10 liters is enough, if the two bathrooms at the same time, it is best to choose more than 16 liters of water. Modern people advocate environmental protection, if you want to choose an environmentally friendly burner water heater, it is necessary to choose a new product: condensing gas water heaters, both energy saving, but also environmentally safe. Condensing gas water heater is an energy efficient and environmentally friendly water heater, installed condensing heat exchanger (i.e. condensing exchange device), by absorbing high-temperature flue gas and preheat cold water, the exercise of common gas water heaters as a waste gas exhaust heat, thermal efficiency increased by more than 15%, while accepting the neutralizer to hold harmless disposal of condensate emissions, real energy saving and environmental protection.
