Which to choose a water heater for the kitchen: flow or storage?

The desire for a comfortable arrangement, not only apartments but also private houses autonomous demands on certain stage of solving the problem, select a water heater to provide themselves with hot water. This question is serious, because it is a fairly expensive purchase, so it should be flawless and long.

Types and mode of action

If we take as a criterion the form of energy use, it is possible to identify several domestic water heaters.

1. Electric storage

The operation of the heater based on the principle of conservation of heat of the heated water, thanks to the special design of the tank, made of a thermos type. Using water heaters warms up to operating temperature reaches 85 ° C, maintaining it in the future automatically. When you open the faucet flowing hot water, which is then compensated by the new portion of the cold, so the volume is maintained at all times in a constant state.

Depending on the displacement volume (10 ÷ 200 l) storage device has a specific power of electric heaters (1,2 ÷ 2.5 kW), which is linked to the heating rate. If the tank is small - 15 liters, the water is heated for about 40 minutes and 200 liter tank require about eight hours. The design of such a heater included thermostat regulating the temperature and pressure relief valve, the bleed excess pressure arising.

2. gas storage

Operating the gas water heater for the kitchen can be a floor (120 ÷ 1000 l) or a small wall (10 - 119 l). In natural gas as fuel is used more frequently, but there is a model having transition mechanism for liquefied gas. The main drawback is considered to need to wait after ignition burners heating the water, wherein this time period can be several hours, if the storage container has a large volume.

3. Electric flow

These water heaters are convenient for the kitchen, since they have no storage tank, which requires free space for installation. The water is heated instantaneously at the moment when the valve is opened, and she begins to flow. The degree of heating is controlled by changing the pressure.

4. gas flow

Before selecting instantaneous water heater must take into account its dependence on the possible changes in the gas pressure in the pipeline or water in the water that does not exist in the storage analog.

By way of installation can pick up a storage device, such as a horizontal and vertical arrangement.

If we consider the kitchen water heater according to operating principle, then we will focus on two groups - pressure and non-pressure devices:

1. In pressureless heaters internal pressure has indicators not higher than atmospheric pressure, by installing a special crane inlet. Most often, such a device is equipped with a shower head, which allows to carry out washing dishes. The device is low-powered and can be connected to the household power without fear of exceeded load.
2. To discharge flow models include types of heaters having inlet to the outlet, intended for the flow of water. In occurs automatically when opening the tap. If the water flow has stopped, and the device stops working. Convenient to mount it in the kitchen cupboard, designed for washing.

Selection of the optimal water heater

When choosing a water heater for the kitchen, drawing attention to the different criteria, since the required amount of hot water.

If we compare the instantaneous and cumulative views of the water heater, the positive development of the last becomes the continued operation of such a device, if the water suddenly decreases pressure. This is important in terms of country of residence, where this problem is common enough.

Convenient storage type water heater chance to wiring and parallel to the feed water at several points, for example, possible to simultaneously wash the dishes and filled bath.

But the flow kitchen analogue thereof provide any amount of heated water, while the drive outputs only its specific amount depending on tank size.

If we compare the electric models, an important advantage is the front of a flow device the fact that the water heater automatically maintains the temperature after it has reached the working indicators. This makes the unit cost, consumes less electricity. Instantaneous heater is not warming water please high, the temperature of which is the smaller, the more powerful the pressure.

Gas appliances is required to be equipped with a sensor responsive to crisis situations to which the flame extinction. Automatic operation leads to the gas supply overlapping. The electric device is embedded thermostat that supports the desired temperature parameters.

However, it should be noted gas flow device for heating the water, which are the most economical. Current models safe in operation, compact, but require special chimney, as distinguished products of combustion. These advantages include the duration of the operation.

Further improvement of the technological scheme allows devices to acquire water heater which is switched to flow mode of operation if necessary. This is especially true for large volumes of heated water, which contributes to reduction of the heating time.

installation methods

There are several ways of fastening, suitable for continuous flow water heaters. Pressure their representatives can be integrated into commonly held in the sanitary zone the water stand pipe providing a few household areas with warm water. Non-pressure flow model is recommended to be placed in the immediate vicinity of the taps, which is convenient in-town suburban conditions.

Accumulating device wall (volume ≤ 150 liters) equipped with a bracket arranged on the housing. exact markings, to drive the hooks and hang water heating equipment to them is enough to make a wall.

If the data sheet indicates that it is a vertical model, not install it horizontally.

Higher capacity (more volume 150 l) interior storage devices are placed on solid ground, which should be perfectly flat. This is sufficient for stability and additional fasteners are not required. Water supply units are connected by a flexible liner. In the network they are connected after being completely filled with water.
