How to choose a boiler?

boiler - water heater storage-type, which is ideal for installation in apartments and country houses.The range of such devices today is very wide, so it is important to know what parameters to look for when choosing a boiler.

Heating method

first step is to decide on the method of heating.This parameter boilers are divided into gas and electric.The first kind of products are low price and economy in operation.But there is also a significant minus: gas boilers require a complicated setup and the need for a separate chimney.That is why many prefer electric water heaters.They are more expensive, but their installation is different complexity.

water heater tank material

The main element of the boiler - a pot, so you should pay special attention to him.First you need to find out what material is made tank.So if it is made of copper or propylene, it lasts about 2-3 years.Slightly longer have a water heater made of steel coated with conventional enamel.They can last for about 4 years.If the coating acts as a titanium enamel, the service life of the boiler will be 7-8 years.

Also, manufacturers offer water heaters with stainless steel tanks.They do not corrode and are not oxidized, so are more than 10 years.But it is important to bear in mind that the longer the lifetime of the device, the higher its price.However, to save on buying it is not necessary, since the boiler is purchased, as a rule, for a long time.It is better if the tank is made of stainless steel or have a titanium coating.

Boiler capacity

tank important parameter - the amount of water heater tank.If he will act as the sole source of hot water, it is important that it was enough for all the needs.In this case it is better to choose large boilers.So, experts advise to buy a water heater for a family of two or three people in a volume of 100-140 liters.If you live in a house of four or five people, then it will need to buy a boiler, designed for 160-180 liters.

Of course, given the volumes are exemplary selection of the boiler in this parameter will depend also on how efficiently your family consumes water.So, unless you plan to frequently take a bath, you can manage devices and at a lower capacity.But if you are due to various reasons will need hot water throughout the day and in large volumes, it is best to opt for a large boiler.

heater power

Many do not know how to choose the boiler capacity.So, if the water heater tank capacity is 120 liters or more, it is better if it will have a capacity of 3-3.6 kW - if the water is to be heated to the required temperature for 1-2 hours.If you plan to purchase up to 120 liters boilers, their power can be from 2 to 2.4 kW.

Number of heating elements

Each electric boiler has a heating element (heater).At the same time in some models it provided just two PETN, which is preferable.It is clear that such elements quickly fail, and if they will have two, then they will last much longer.If one heater burns, the other will continue to operate, which means you will not be left without hot water.Furthermore, when in very hot water, there is no urgent need, you can use for heating is only one heater, thereby reducing the load on the network.

Choose manufacturer

buying a boiler in an apartment or cottage, you must pay attention to the producer, as from the quality of the water heater depends largely.It is better to give preference to established companies by the manufacturer, for example, Gorenje, STIEBEL ELTRON, AEG, Aquavesto, Bosch, Electrolux, Ariston, Vaillant, Vektor and others.
