Of 6 kinds of the best gas water heaters: how to choose which one to buy, the pros and cons, features, rating

Installation of gas water heater in the apartment or private home ever save you from the problems with hot water. Even with the constant modernization of utilities networks, in some cases, their power is not enough.

How to choose a gas water heater

All gas water heaters are divided into 2 types:

• savings - devices with large dimensions because of the presence of the hot water tank, whose volume may be from 50 to 500 liters. Due to the large weight of the layout is almost always floor, and installation requires sufficient free space. It is advisable to use these heaters in cottages and private homes.
• Flow - compact device without the water tank. Suitable for installation in small spaces with natural ventilation. Good solution for hot water in the apartment. A characteristic feature - a relatively low productivity.

Selection of a suitable gas cylinder based on the following criteria.

Performance

Indicator measured in l / min, and indicates the amount of water which is capable to warm up per unit time. The required capacity of the equipment is chosen taking into account the amount of intake points, e.g., mixers. It is considered that one point for service requires the performance of about 6 l / min, and to use simultaneously two mixers - 13 l / min.

inlet pressure

The value consists of two parameters: the maximum and minimum pressure. The first indicator indicates a pressure device which is able to withstand. Jobs running water is often accompanied by hydraulic shocks, which may cause damage water heater. For domestic networks it is recommended to select a model with a maximum pressure of 11-12 bar.

As regards the minimum pressure for achieving it turns speaker. If the pressure is below this value, the device simply will not work. This is especially true for the flow type models. The recommended minimum pressure - no more than 0.15 bar.

ignition type

• Manual. Hardly used, even on low-current models due to insecurity and inconvenience.
• Pezorozzhigom. Is activated by pressing a button, is integrated in an electromechanical device match. It has no special advantages over the one described above.
• Electric ignition. An improved system, which may be volatile and non-volatile. In the first case, when de-energized heater just turned off. The second option is connected to the household power outlet using an adapter. In turn divided into hydro (powered by electricity generated by the flow of water) and a battery-powered device.

type of heat exchanger

• Steel - have high reliability and low cost, but weigh much and are susceptible to corrosion.
• Copper - have a short service life due to the presence of impurities, which lead to uneven heating. heat-resistant coating paint not really save the situation.
• Because high-purity copper - compared to steel have increased efficiency under similar mechanical characteristics.

Method discharge combustion products

• Classic (chimney). Often installing heaters in this way removal is impossible due to simple lack of technical capacity, for example, in an apartment.
• Parapet (with no chimney) - a more expensive option. Retraction is performed by forcibly withdrawn out of the tube. The main requirement for the room where the water heater - quality ventilation.

security devices

The presence of each of the following devices necessarily in that if a water heater is installed in the living room, not in a specially equipped boiler:

• Detectors: ionization, flow, presence of traction, low water pressure.
• Sensor water overheating.
• Safety valve performing emergency discharge fluid when the pressure in the pipes.

The absence of one of the devices reduces the safety of the water heater, can lead to negative consequences for health, life-threatening.
