What to choose for a shower in an apartment according to the expert?

Choosing a flow-through water heater, first of all, you should assess the planned scale of its use.

If the device is needed only for washing dishes in the kitchen or morning washing, then it is not worth overpaying for high-powered models, which place high demands on the electrical wiring.

But for regular bathing and water procedures you need a very powerful device.

So, before you buy the model you like, you should pay attention to such indicators as:

• device power - The capacity ranges from low-powered 3-5 kW, supplying about 1.5-5 liters of hot water per minute, enough for a quick shower or washing food and dishes, to devices that consume about 30 kW and can provide hot water to all the bathrooms, bathrooms and kitchen corners of the apartment;
• capacity - is a parameter usually indicated in the certificate which is often calculated on the basis of an initial water temperature of 20°C that in Russia can be found only in hot summer or in the warmest southern regions (in most Russian cities the incoming water temperature in winter and during the off-season is not higher than 10°C)
• anticipated load - you only need a heater for 1 tap or you need to provide hot water to several locations;
• filters - as the water in our pipes is far from ideal, a system of good filters will seriously extend the life of the device;
• control type - mechanical, which works on the principle: the greater the water pressure, the colder it is, or electronic, automatically adjusting the temperature of any water flow to the values selected by the user;
• electricity - For heaters of small capacity (up to 8 kW) will be enough usual outlet, powerful models, most likely, will require a separate protected electric line of 380 V (three-phase voltage) from the switchboard to the socket in the apartment;
• design and dimensions - The device should fit well into the interior of the room or be well placed behind closed cabinet doors;
• warranty service - long warranty period indicates the high quality of the device, and the service center, located in your city, will expedite service and maintenance of the device.

• unpressurized devicesProviding water heating only in one point of water intake (or in two, located in close proximity to each other);
• pressurizedThe hot water inlet and the hot water outlet can be routed to all the consumption points in the apartment by means of internal piping.

What company to choose?

When choosing a flow-through water heater, you should give preference to reliable and proven manufacturers, such as:

• Thermex - An international group of companies, the largest specialized manufacturer of water heating equipment;
• Bosch - well-known German company, whose products are traditionally of high quality;
• Electrolux - is a Swedish company, one of the world leaders in the production of household and professional appliances;
• Stiebel - a company associated with hot water and distinguished by the high technology and cost-effectiveness of its products;
• Timberk - Swedish brand, owned by Arima Holding Corporation, which specializes in the manufacture of HVAC equipment;

Flow-through water heater or storage water heater (boiler) - which is better?

Choosing between the flow-through and storage water heater, it should be borne in mind that such a decision should be made, based on the purpose of using the device and the amount of hot water required: so, for a summer house, where 1-2 people live irregularly, the flow device is better suited, and for a city apartment with 5-7 households will be more economical to purchase a large boiler.

Also to the advantages of flow-through heaters traditionally include:

• low cost;
• compact size;
• instantaneous water heating;
• unlimited amount of hot water;
• interval consumption of electricity (only during operation).

And among the disadvantages of such a device leading quite a large power consumption, which is not the best effect on utility bills, increased requirements for the electrical network of the room.

You should also keep in mind that in winter the temperature of incoming water will be somewhat lower than in summer, respectively, and the hot water coming out of the device of small or medium capacity, will have a lower temperature, not too comfortable for prolonged water procedures.
