Why do you need a storage water heater under the sink in the

Do you turn off hot water in summer, and in winter it is not of very good quality? Now you can forget about this problem - electric water heaters came to the rescue. For domestic needs, manufacturers offer models of different sizes - from 5L.

Connect to the water supply system such equipment does not pose a problem. Today we will talk about devices that allow the kitchen to always be with hot water.

Storage water heater design

Before choosing the right equipment, it’s worth exploring how it works, as well as what are the requirements for it in the first place.

1. The main thing is that the tank be able to keep the required temperature as long as possible, so in this case one cannot do without high-quality thermal insulation of the boiler. Because of this, the price of the device may increase.

Tip: the thicker the material layer, the less energy is needed to maintain the set water temperature.

1. Inside an electric accumulative boiler of any size, the heating elements are installed. Due to the built-in thermostat it is possible to regulate them. The equipment, when it reaches a predetermined level, will disconnect the heating elements from the power supply network, and also turn them on when the temperature drops below a certain limit. The warm-up time depends on the power of the heating elements, the capacity of the electricity grid and the volume of water.

Tip: for the kitchen and the sink suitable volume of 5-15 liters.

Advantages of equipment

Accumulative electric water heater has a number of features that distinguish it from other devices of this kind, in particular gas.

Mark should:

• heat exchanger power;
• no need to install a chimney to divert combustion products;
• there is no combustion chamber, therefore maintenance is simplified.

Most modern models of electric water heaters have a night mode of heating capacity.

1. When choosing equipment, specify the basic parameters for its proper operation.
2. Most models are mounted with special brackets.
3. The device, unlike the flow-through, instruction allows to combine with an individual water supply using a pump for a well or a well.
4. Factors affecting the correct operation of the boiler:

• sharp temperature drop;
• ingress of aggressive substances;
• high pressure in the water supply network.

Tip: choose electric storage water heaters with anti-corrosion coating, which can protect the device from damaging factors.

Cumulative boiler for the kitchen

Electric storage water heaters that are small in size have recommended themselves in the kitchen. Their volume usually does not exceed 30 liters, and we recommend to install them in the case when the power of the wiring does not allow to install a flow-through electric heater.

The device is very economical, which is confirmed by many users. Produce two types of devices - for installation above and below the sink. Between themselves, they differ in the outlet pipes for connection to the water supply.

Tip: buy at once such a device that you need, because you can not mount the connections can not be replaced.

Valve

The installation instructions for the boiler require the installation of a check valve in the water supply system, which must also be combined with the safety valve:

It is often possible to observe during heating how water begins to ooze; there is nothing dangerous in this phenomenon, since in this case the water begins to expand - the safety valve will do all the work.

Tip: if the boiler is large enough in volume, we recommend installing an expansion tank between the non-return valve and the heater so that a certain percentage of hot water flows into it when it expands.

It is possible to drain off excess water in another way - attach a tube to the valve nozzle, which is then lowered into the sewer pipe. Experts recommend installing a safety valve above the water heater, it is necessary to take into account the direction of water movement, which is indicated by the arrow on the device. Leave free access to it.

Malfunctions due to the fact that water begins to flow from the valve:

• if the water heater just turned on. This may be due to a manufacturing defect in the valve itself;
• when valve installation occurred incorrectly.

We recommend screwing the check valve 4 turns, but no more, so as not to disturb its adjustment. In case of contamination, it is better to replace the device.

Materials for equipment installation

Before installing the water heater, check whether you have everything to connect it to the water supply.

You must purchase:

• 2-3 ball valves, depending on the connection method;
• connecting pipes, for example, metal-plastic O?. Metric area should correspond to the distance from the device to the pipe. You can use flexible eyeliner, but it has a limited shelf life;
• fasteners for pipes to the wall and between themselves - clips and fittings;
• water filter;
• pressure regulator.

For electricity supply:

• cable - three-core copper, the cross-section of one conductor must be from 2 mm;
• fastener for cable or duct.

Water heater installation

You can take the water from the kitchen heater to the washbasin and into the bathroom, then you will have to double the wiring.

1. Fastened to the wall - using a drill with a pointy drill, mounting rail or anchors. Note that in the filled state the device is heavy, especially when it is designed for 30 liters.

Tip: do not want to engage in hard work, purchase equipment for installation under the kitchen sink on a special stand.

The wall should be concrete or brick; if it starts to crumble, use a longer anchor. Take a drill and drill the required holes for the diameter. Insert anchors into them with your own hands and fasten them with a wrench.

Tip: if you have to install on a wall of foam blocks, foam concrete, drywall and similar materials, be sure to use the appropriate fasteners.

1. We connect to the water supply.

Use for this branch pipes for cold and hot water on equipment that are painted in the appropriate color:

• "Blue" - for cold;
• "Red" - for hot.

First, attach a safety valve to the blue pipe. Then screw the check valve on it. Put up 2 ball valves. Check all parts for tightness.

Tip: use for threaded connections tow or special plumbing fum-tape.

We recommend to connect the boiler to the water pipes using metal-plastic pipes, they are much more resistant to pressure drops and hydraulic shocks. Use fittings for installation.

1. We connect electricity. The installation of the equipment is calculated on the fact that the electrical cable must be connected directly to the panel. The machine should quickly shut off if an emergency situation occurs. Take special permission for this is not necessary.

Conclusion

Hot in the kitchen for many residents of small towns in the warm season was not available. However, with the advent of storage electric water heaters, this issue was resolved in a positive direction.

Installation of the device under the sink will not be difficult, you can do it yourself, having the appropriate skills. The video in this article will provide an opportunity to find additional information on the above topic.
