The reliability rating of gas water heaters helps consumers navigate among the abundance of offers on the market for water heating equipment. It widely presents products from world famous brands and from little-known manufacturers, prohibitively expensive and suspiciously cheap. In order not to make a mistake with the choice, you have to delve into the technical parameters of gas equipment that determine its capabilities. But first you need to choose a brand – this review of the best speakers in 2018 will help with this.
How is the reliability rating compiled?
Each manufacturer claims that it is his gas water heater that is the best, modestly silent about the shortcomings. Modern gas water heaters must meet requirements that their predecessors could not even dream of. Instead of unsafe and capricious appliances that are always going out, kindled by matches, making pops and heating water unevenly, the market offers completely safe, convenient, economical and, most importantly, reliable devices that make life easier. Reliability is one of the key qualities by which the consumer evaluates any equipment. Experts are not going to take a word, they periodically evaluate products of different brands, basing their conclusions on performance, sales results and real reviews. Based on the results of the work, a reliability rating is compiled – gas appliances of different brands are lined up in descending order of this indicator. When compiling our rating, applicants were evaluated by:
- quality;
- price;
- reliability;
- uniqueness.
The rating starts with models with a built-in display – it makes the use more comfortable.
Top 10 gas water heaters 2017
Vaillant atmoMAG OE 11-0/0 XZ C+ H
All experts and users are unanimous: the best gas equipment is supplied by German manufacturers. Their trademarks are the constant leaders of any ratings. Germany has established very strict control rules for compliance with international standards, which positively affects the quality of the finished product.

Power 20 kW. Productivity on water — 10 liters per minute. The maximum heating is 80 °С. This option is suitable for a family of 3-4 people, it can serve several points at the same time.
How to choose?
When the brand decision is made, you can start choosing the right model. Before that you need:
- Find out how much hot water is supposed to be consumed.
- Measure the pressure in the gas pipeline and water supply.
- Measure the draft, if necessary, clean the ventilation duct.
- If the house is private, do the arrangement of the chimney.
- Decide on dimensions.
The selection of a suitable option is made taking into account the following parameters:
- Power. Performance depends on it – how quickly the water will heat up, which means how comfortable it will be to use. The more power, the more points can be served simultaneously. Based on the needs, the appropriate power is selected. Versions up to 20 kW are low-power, they are taken for one point of water intake. They heat water at a rate of 10–11 l/min. For 2-3 points, you need a more powerful option.
- Ignition type. Modifications with piezo ignition are cheaper, but in them the wick burns constantly, gas is wasted. Electric ignition is a more relevant and economical solution. But even here there are nuances. If the ignition is from batteries, they need to be changed annually, if from a hydraulic turbine, a good pressure is needed.
- Burner type. All expensive devices use a modulating burner. Such a device provides a stable outlet flow temperature, the user does not have to worry about pressure changes in the water pipes.
- Safety. Gas equipment has always been considered a source of increased danger, but this does not apply to modern columns: so many safety steps are used here that risks are excluded. Any trouble – the appearance of reverse thrust, the extinction of the flame or other dangerous situations – is immediately diagnosed by the protection system, which blocks the device. The gas flow stops, the device is turned off, the accident is prevented.
- efficiency. It should be in the range of 84-90%.
Useful Tips
Even the best and most expensive speaker can fail if the user violates the rules of operation. For the device to work properly and for a long time, you need:
- Trust installation only to specialists. The quality of the device depends on the correct settings.
- Monitor the temperature of the water flow – at the outlet it should not be higher than 60 ° C. This will prevent scale formation.
- Install an anti-scaling system if the water is hard.
- Be aware that when the appliance is in operation, it is forbidden to adjust the temperature.
- Clean the igniter and heat exchanger regularly.
The geyser allows you to organize hot water supply: independent and autonomous. The owners of this equipment are not afraid of power outages or hot water, they will always have the opportunity to take a bath or shower. And if you choose a model with the ability to switch from natural gas to liquefied gas, then independence from centralized communications will be minimized. The reliability rating includes both imported and domestic models.
