Independent power supply: an inverter or generator Bashny.Net

The heating system with natural circulation of the outage will take place completely unnoticed. But when it comes to energy-boilers, support health system at the time of "no light" is very relevant, or, in the extreme case, this may even lead to the freezing system. On top of that, some models of boilers do not allow freezing of coolant (antifreeze for heating systems), and this is another reason to purchase an uninterruptible power supply.


A lot or a little

Initially, you need to determine the maximum number of devices, continuous operation which will ensure the safety and comfort. It is desirable to set priorities and find only those that are necessary for the normal heating system is working. Automation of boiler, pump group, house automation definitely should not be left without food, but if several appliances can add needed to this list (for example, a refrigerator or a water purification system).

rinimaya into account the required peak power (maximum power consumption of all devices), estimated time of operation of the system in the "avtonomke", the value of inrush current for all devices and power margin of 10-15%, it is possible to determine the version of the uninterruptible power supply: batteries with an inverter (inverter is required to convert the voltage 12-24 V batteries into the usual 220) or higher-power generator.

Saves

The use of an uninterruptible power supply with the inverter-based batteries is appropriate when it comes to, say, a wall-mounted boiler, for outdoor gas or solid fuel, or any other group with a small pump and energy-intensive automation. Unfortunately, energy-boilers was not originally planned to install the UPS, but many organizations that sell and installs heating equipment, rechargeable bespereboynik offer as an option. There you can help with the calculation and selection of battery capacity and power, and installing it in parallel with the boiler installation. In addition, there is a fairly specialized companies and stores that offer a wide range of equipment and solutions to ensure the smooth operation of the heating or domestic appliances during a power outage.

UPS operating time depends on the total power of devices, the number and capacity of batteries. The range varies from 40 to 200 ampere-hours, in other words, from 10 minutes to several days. Undisputed plus inverter with batteries is that its installation requires only one person - a qualified electrician

If the electricity is cut off for a long time or a lot of power is required to maintain the peak flow rate, it is better to pay attention to power-generators. This type of equipment is capable of operating on different fuels: a natural or liquefied gas, diesel fuel, fuel oil, gasoline. When choosing a generator is appropriate to bind to fuel the boiler.
Generator power plant is an internal combustion engine, which is similar to the care of the maintenance of automobile engine. It's quite noisy unit, also when it is necessary to consider the need for placement in the exhaust gases or products of combustion.

Often generator allocate a separate room with a good ventilation system. A wide power range - from 1-1, 5 kW and 100-200 kW, and even up to 1000 kW - makes it possible to not only support the efficiency of the heating system, but also provide energy to all appliances. And if you provide automatic start-generator power at the time of termination of the electricity supply, neither man nor transfer technique will not even notice, of course, provided that the generator tank is not empty.

By the way, when you install a generator running on natural gas trunk, it is necessary to agree on the issue of the installation of additional gas equipment at a local gas service.

generator operating time depends on the fuel consumption and the capacity of the fuel tank. It is also necessary to take into account the total power consumption of all devices. In reality, the generators operate somewhat longer than calculations show, because they go on peak loads, and the inclusion of technology does not always happen at the same time.

Combination

You can use both types of CHD. With short-term power failure the inverter is running on batteries, while longer full load will take on generator power plant.
