TOP-8 best gas flowing water heaters
The presence of hot water today is considered one of the indicators of comfort. An instantaneous gas water heater is a practical device. For more than a decade, flow-through gas water heaters have made it possible to use this benefit of civilization around the clock. It heats the water almost instantly.
How to choose and what to look for?
When choosing an instantaneous water heater, you should pay attention to the following parameters:
- Power... The performance of the device depends on this parameter. It is worth considering the number of people who can use hot water at the same time. For example, a 17-20 kW appliance is suitable for 1-2 people and heats 10 liters of water per minute. To use 2-3 mixers at the same time, you need a unit with a higher power from 20 to 26 kW. For large private houses, it is recommended to install appliances with a power of more than 26 kW.
- Performance... Shows how much water the column heats up in one minute. This indicator is indicated in the documentation for the product. Since one tap passes 6-7 liters per minute, a gas heater with a capacity of 13 liters per minute is suitable for an apartment with two mixers.
- Heating temperature... The more the water heats up, the more you can save cold water. Units that heat water to 75-80 ° C are considered optimal.
- Internal coating of the device... The columns are made of steel and copper. Steel is a more budgetary material, but despite this it is quite practical, since it is resistant to corrosion and high temperatures. The main advantage of copper is its greater heat transfer.
- Type of ignition... Gas is started by turning a knob or pressing a button. The second option is the most convenient, since direct contact with fire is excluded.
- Combustion products removal... Water heaters come with and without a chimney. The first option is suitable for residents of private houses. Models without a chimney are often installed in city apartments. To remove the combustion products, a hole is made in the wall and forced ventilation is organized.
