Operation of gas boilers in many respects depends on uninterrupted and high-quality power supply. Because of voltage surges and frequent power outage the boiler equipment can quickly fail. Therefore for boiler the reliable source of uninterrupted power is necessary.
Uninterruptible power supply units
Uninterruptible power supply units are necessary to create constant electric connection. They allow to continue work of gas boiler at power outage.
In comparison with gasoline-driven and diesel electric generators, uninterruptible power supply units have the following advantages: - higher coefficient of reliability;
- simple mounting and connection; - it is more than time of time between failures; - silent work; - there is no need for constant service and replacement of consumables.
Bespereboyniki satisfy number of the conditions necessary for high-quality power supply of circulating pumps and the electronic block of gas boiler. Treat these conditions: the sinusoidal form of tension, high accuracy of sizes of tension and frequency filtering properties, protection from deep discharge of accumulators, the wide range of input voltage.
Types of the UPS for gas boilers
There are three types of sources for joint operation with gas boilers: linear, linearly - interactive, the UPS of double transformation. The most simplified model is the linear uninterruptible power supply unit. Tension on entrance and the output of the device does not change as in its design are not available power conditioners for gas boilers. Such source has possibility of detachment from the power supply network, passing at the same time to power supply from accumulators. In linearly - the interactive UPS there is simple power conditioner. If to connect the external battery, such source will ensure functioning of gas boiler without connection to current network till ten o'clock. At the output of the UPS the sinusoidal signal, with characteristics of 50 hertz and 220B turns out. The uninterruptible power supply unit of double transformation besides back supply provides voltage stabilization. Except possibility of stable operation of the boiler at the voltage of 110-300B and filtration of hindrances, there is opportunity to connect the gasoline-driven generator.
Accumulators for uninterruptible power supply units
It is possible to connect several accumulators to uninterruptible power supply units, having increased these duration of its independent operation. At the same time it is necessary to trace that all accumulators in the battery were the same capacity and had the identical level of charge. Otherwise they will be unevenly discharged and not to turn out to achieve the long period of independent operation. The UPS accumulators can be turned on consistently and in parallel. If to include consistently, accumulator capacity does not change, and tension develops. At parallel inclusion tension does not change, and battery capacity increases in proportion. Sometimes for the sake of economy together with bespereboynik use automobile accumulators. It is not necessary to do it because the wrong connection of accumulators will put uninterruptible power supply unit out of action, in this case it will not be replaced on guarantee. The most suitable option – hermetic accumulators which are intended especially for uninterruptible power supply units.
Having connected several accumulators, arrange them so that between them the air gap was formed. Otherwise they in addition will heat up from each other.
Accumulators are quickly discharged in heat therefore they should not be near heat sources. Low temperature too quickly discharges them therefore the best option is to hold them at the room temperature.
How to choose uninterruptible power supply unit
Choosing bespereboynik for gas boiler, it is necessary to pay attention to time of necessary autonomy and power consumption. In this case the electric power of circulating pumps and automatic equipment of boiler means. For pumps high starting currents are inherent, because of it their power needs to be multiplied by three. Power of boiler can be specified in the registration certificate of product.
The small uninterruptible power supply unit of wall type of fastening will be suitable for the dacha and the house.
In addition decide on necessary time of autonomy, it depends on the capacity of accumulators and power of loading. At the high capacity and smaller power of connections of loading longer autonomy time. As it was already mentioned above, the necessary battery life is provided with connection of different number of accumulators. But it does not mean that it is necessary to collect system by the principle "longer works – works better" as its cost to increase with increase in number of accumulator batteries. Collect set, making a start from work of your network. If short shutdowns are characteristic of it, you should not overpay and collect system which will provide self-contained electric supply for day.
