One of the main benefits in a house or apartment is the presence of hot water. The lack of a central warm water supply system forces the owner of a house or apartment to install one or another water heating system. If there is gas in the dwelling, it is often the best choice to solve the problem of hot water supply is the gas water heater. In this case, it is she who will be the most economical to use, compared to electric water heaters.
Any specialized company will be able to offer you a huge selection of models of gas water heaters of various capacities and prices. A non-specialist can easily get lost among them without knowing all the subtleties and features of such equipment. So you can definitely decide which model will be a good purchase for your home, we have made a rating of gas columns in terms of reliability and quality. The rating was based, first of all, on reviews and ratings of users of this equipment, as well as their main technical characteristics.
First, find out what kind of gas column you can find on the market and tell you about their main advantages and disadvantages.
First of all, experts divide them into two groups:
The geyser has small dimensions, so that it is well suited for city apartments. A gas column is connected directly to the cold water system. Such units can work on both natural and liquefied gas. Passing through the heat exchanger, the water quickly heats up from the high temperature of the combusted gas and is already heated immediately supplied to the mixer. Geysers are equipped with advanced security systems to ensure reliable and safe operation.
Flow gas device:
1 . Thrust Detector;
2 . Overheating detector;
3 . Gas burner;
4 . Gas intake regulator;
5 . Hot water outlet;
6 . Exit for chimney;
7 . Collector for combustion products;
8 . Heat exchanger;
9 . Gas pipe;
10 . Water intake regulator;
11 . Outlet for cold water.
The main difference in the device and the principle of operation of the storage gas heater is that the heated water in it does not go into the water supply, but is stored in a special capacity. Water heating does not occur simultaneously, but gradually. Accumulative capacity has good warming that promotes longer preservation of temperature of the prepared water. As the water consumes or cools, the water in the tank is automatically heated to the set temperature. Among the many models on the market, you can easily choose the one that provides you with the right amount of water. You can find both a column for the kitchen, the tank of which is about 50 liters, and a bath device with a tank of 100 liters and more.
Cumulative Gas Heater Device:
1 . Gas flow valve;
2 . Gas adjustment knob;
3 . Water temperature adjustment;
4 . Gas-burner;
5 . Ignition gas wick;
6 . Thermocouple;
7 . Main gas burner nozzle;
8 . Internal sheeting;
9 . Thermal insulation water tank;
10 . External protective cover;
11 . Shutter;
12 . Anode to prevent scale and corrosion;
13 . Drain cock;
14 . Cable from the detector thrust;
15 . The base of the chimney;
16 . Divider;
17 . Cold water inlet;
18 . Swirler of water flows for intensification of mixing;
19 . Emergency relief valve socket;
20 . Pipe coming out for hot water;
21 . Stabilizer thrust.
There is no place for installing surround equipment . In contrast to the cumulative column, which includes a tank with a volume of tens or even hundreds of liters, the flow-through column is small in size, which makes it possible to install it with minimal expenditure of free space in the room.
Restricted Budget . Flowing gas water heaters are much cheaper than cumulative. The difference in cost can go up to 3 - 6 times.This factor contributes to a greater distribution of flow through gas columns.
Reliability and durability . If we compare the two heaters, the flow through will be more reliable, since it uses fewer different systems and mechanisms.
There is a large number of water consumption points with a high probability of simultaneous use of . If it is assumed that several people will use the hot water at the same time, then in the case of using a flow column, there will be a decrease in water pressure and an increase in its temperature. Storage heaters of this disadvantage are deprived. In this case, the storage water heater will be your best choice.
Unstable gas pressure . Heating does not occur immediately, but gradually - depending on the capacity of the model and the volume of the tank, this takes from several minutes to several hours. Therefore, it is not necessary to consume a large amount of gas in a short time, which means there will not be a sudden load on the gas pipeline. In the case of a flow column, all gas pressure surges will affect the water temperature, in the case of a storage heater, this will only affect the rate of water heating in the tank.
The need to heat water to higher temperatures . The water in the storage water heater is able to heat up to a higher temperature. All models have the function of adjusting the maximum temperature. The user can set the optimal heating level to reduce gas consumption and reduce costs when paying utilities. High-quality thermal insulation ensures that even a few hours after heating, the water will keep the temperature high.
Low cold water pressure . If a low water pressure is observed in a cold water supply system, then the operation of a flowing gas column will be difficult or even impossible. In turn, the storage water heater is able to operate at a sufficiently low pressure.
Weak smoke exhaust system . Flow heaters are more powerful devices and require a larger diameter chimney (110-130 mm). Gas boilers are less powerful devices and do not form, at one time, such a quantity of exhaust gases, which allows them to be used with a chimney diameter of 90 mm.
Poor quality cold water . In regions with hard water, scale formation may occur. Over time, the salt layer on the inner walls of the spiral heating element of the flow gas column will increase, which will reduce the efficiency of the heater, as well as its heat transfer. In the case of accumulative gas heaters, this problem is less acute.
