Answer: The choice of gas water heater mainly depends on the following points.
1, gas type;
When buying a gas water heater, you must first confirm what gas is used at home. If you use natural gas at home, choose the water heater marked "T"; If you use artificial gas at home, choose the water heater marked "R"; If you use liquefied gas at home, choose the water heater marked "Y".
2, the choice of the number of liters;
Gas water heaters have different liters, such as 12L, 13L, 16L, etc. Consumers should decide which gas water heater to choose according to household water consumption to ensure normal water use.
3. Safety;
Gas water heaters can be divided into four categories according to the exhaust mode: direct exhaust type, flue type, forced exhaust type and balance type. The mainstream in the market is forced exhaust type and balanced type, in which the exhaust gas generated by combustion is forced to be discharged outside, and the balanced type is to extract outdoor air for combustion, and the generated exhaust gas is forced to be discharged outside, so these two types are safer among all gas water heaters.
4. Constant temperature effect;
There are three ways of constant temperature for gas water heaters: gas proportional valve constant temperature, water-gas dual-tone constant temperature and water server constant temperature, among which the water server constant temperature effect is the best, followed by water-gas dual-tone, and finally gas proportional valve. Consumers should pay attention to their choices. At present, Enrique gas water heater is water-gas dual-tone constant temperature, and the cost performance is more applicable.
