We choose boilers
The first cold money makes you think about heating your own home: an apartment or a private house. But the shocking variety of models of water heaters (boilers) suggests: "Which is preferable to choose and install?".
For example, a prestigious electric water heater of the Lux class is:
• unique "Antimix" system, which excludes mixing of heated and cold water layers
• A significant utilization factor of heated water up to 90%
• stainless steel tank with a wall thickness of 2 mm
• two layers of external protective titanium enamel
• reinforced layer of thermal insulation made of polyurethane foam
• secure double wall mount
• original design.
To understand the issue of selecting and installing a boiler for a house helps the advice of a home master.
For what purpose are the boilers
Successfully solve the problem of the lack of hot water supply water boilers allow, which are divided into the following options:
by type of coolant
• electrical
• gas
heating method
• Indirect
• combined.
Naturally, the appointment of electric and gas boilers is the heating and heating of a private house.
Helpful Tips
The first voluminous barrel-shaped boiler designs go into the past, giving way to more practical flat models of water heaters. The flat shape of the boiler makes it possible to solve the problem with a lack of space. Therefore, flat-plate boilers are successfully selected and installed almost everywhere.
What are electric storage water heaters
design
The boiler is exaggerated as a multi-volume container (volume from 10 to 180 liters). Inside the tank there is a heating element (TEN), whose power can reach 2.5 kW. The maximum temperature of water heating can be 80 degrees. To eliminate the inevitable heat loss, the tank is insulated.
The thermal insulation is located between the outer casing and the inner receptacle. To prevent corrosion inside the steel tank inside the magnesium anode is installed with a regular preventive replacement.
An important element of the water heater is the thermostat, by means of which the thermostat automatically switches on or off the heating element when the temperature regime changes.
Recall that the time of heating the water depends on the volume of the boiler and its nominal power, so when selecting it is necessary to pay attention to these parameters.
How to choose a boiler, shown in the video.
How to install an electric boiler yourself
methods of attachment
There are the following types of boiler for the house:
• Wall-mounted version
• floor models.
When choosing the method of attachment and installation, it is recommended to orientate yourself to the weight of the water heater. If the weight of the heater is considerable, it is preferable to install the floor model. When the boiler is wall mounted, it can be placed vertically or horizontally.
There are universal design models that allow you to fix the water heater vertically and horizontally when installing a boiler in the house. To reduce heat losses along the entire length of the pipeline, the boilers are attached as close as possible to the water extraction point. Boilers are fixed with anchor hooks, anchor bolts or pins using bracket and 12mm steel fasteners.
Mounting brackets on the wall, ideally, should "hold" weight, three times the total weight of the water-filled boiler.
Helpful Tips
When selecting the fastener elements for boilers, the anchoring anchors are still leading. To install a water heater you will need: a powerful perforator with a drill of the required diameter, two drilled holes in the wall for installing the anchor and the water heater can be safely disposed and connected!
Install the mounting anchor with your own hands after watching this video will be easy.
We connect the boiler to the water supply system
Before starting the connection to the water boiler system for heating the house, it is not unreasonable to familiarize yourself with the recommendations of the manufacturers in the instructions accompanying the water heater. The connection can be upper and lower.
The most accessible is the installation and connection with the use of metal-plastic or polypropylene pipes. It is necessary to connect the boiler according to the wiring diagram, using a regular shut-off valve. The water heater must be positioned after the meter and the main water inlet.
Connections begin with the connection of tees into the main pipes of cold and hot water. After placing the tees, valves are installed at the boiler inlet and outlet. Then, install a safety valve and check for leaks.
Electrical connection
When the boiler capacity is more than 12 kW, a three-phase power supply is necessary to the house. The boiler is connected to the mains by a separate cable to the power supply panel "directly", according to the standard cable color identification: phase - brown, zero - blue, earth - yellow.
Especially carefully it is required to observe the phase for water heaters with electronics.
The power supply is directly connected to the clamping terminals of the thermostat. Recall that, without fail, a circuit breaker is installed in the power circuit to disconnect and open the circuit.
This can be a two-pole circuit-breaker fuse at 16A, with a contact distance of more than 3mm.
There are rules for choosing a cable that depends on the power of the heater:
• for a 1.5 kW heater, the section of the stranded copper cable should be 1.5 mm with a cutoff current of 10A
• for a heating element up to 2.5 kW, a 2.5 mm cable section is recommended with a similar cutoff current.
For more information on how to connect the boiler to the water mains and the electricity network, see here.
Gas Water Heaters
Boilers gas, in comparison with electric water heaters, have more comfortable operational qualities. The capacity of gas boilers can reach 30 kW.
However, for connection of gas boilers, you must have permission to connect and conduct a regulated professional connection.
