How to choose an uninterruptible power supply (UPS) for a gas or solid fuel boiler

Comfort and safety during the colder months depend on keeping your house warm. Boilers powered by gas or solid fuel are frequently used for heating, but they require electricity to operate. They are susceptible to power outages because of this dependency, which can leave you without heat when you need it most.

A UPS is a device that can be used to solve this issue. When the primary power source fails, it automatically steps in to serve as a backup power source. However, it can be difficult to select the best UPS for your boiler because there are so many options available.

Prior to getting too deep into UPS selection details, it’s important to know what your boiler system requires. Boilers powered by gas and solid fuels have different power needs, start-up currents, and voltage fluctuation sensitivity. You can choose the right UPS capacity and features by weighing these factors.

Make compatibility with your boiler system and dependability your top priorities when choosing a UPS. Choose a UPS that can provide enough power to keep your boiler operating efficiently during power outages. Furthermore, take into account functions such as voltage regulation and surge protection to protect your boiler from fluctuations in power.

Choosing the right uninterruptible power supply (UPS) for your gas or solid fuel boiler is crucial for ensuring continuous heating during power outages. Firstly, assess the power requirements of your boiler to determine the appropriate UPS capacity. Consider factors like startup power surges and ongoing power consumption. Next, opt for a UPS with sufficient battery runtime to cover the duration of potential outages in your area. Look for features like automatic voltage regulation (AVR) to stabilize fluctuations in power supply, safeguarding your boiler from damage. Additionally, prioritize UPS models with surge protection to shield sensitive electronic components from voltage spikes. Lastly, ensure compatibility with your boiler system and consider factors like installation ease and warranty coverage for peace of mind. By selecting the right UPS tailored to your boiler"s needs, you can safeguard your home heating system against power interruptions effectively.

3 criteria for selecting a power supply unit

Following a power outage, the boiler breaker has to take over as the external power supply right away and keep the heating system running until the power source is restored.

Simplified, an LPS works on the following principle: when in normal mode, it charges its own battery and transforms the alternating stream into a constant stream. A reversal process occurs when the power source is cut off; the battery’s constant flow becomes a variable flow that is fed into the boiler.

Online retailers offer a wide range of backup power supply unit varieties at different price points. Consider the following three factors when selecting a UPS to avoid overpaying:

• consumed power of the boiler and other equipment – additional pumps, fans, electric actuators on mixing valves, thermoregulators;
• duration of autonomous operation;
• quality of electricity in the area of residence.

Note: When we refer to an inadequate power supply, we mean that there should be frequent disconnections, significant network voltage fluctuations, or the use of a gasoline generator.

Let’s now examine the aforementioned elements in further detail.

How to determine the power capacity of a gasoline generator

The "breakerless" needs to be able to withstand a high starting jet because circulation pumps in contemporary heating systems may have a ratio of 1 to 10. When the unit is first started, it will increase by at least two times (or, with more powerful water supply system pumps, by three times). The following formula is used to determine the power supply unit’s capacity:

1. We can determine the energy consumption of each piece of equipment – boiler, individual circulation pumps, fans or dimensional pumps of the boiler, electric drives, pellet/diesel pellets.
2. Summarize the data, multiply the result by 2.
3. Select a pump with the same capacity (or higher).

Scrubbing only allows us to change the pump and fan motor power because the electronics aren’t able to produce a starting jet. But since electronic systems account for such a small portion of overall energy consumption, it makes no sense to specify them.

Dovidka. The unit’s passport or the plate fastened to its body both list the gas wall-mounted boiler’s capacity. As seen in the picture below, this parameter is typically indicated on the end of the pump, next to the screw.

Utilization. A gas boiler unit uses 130 W, and an extra pump uses an additional 82 W. The uninterrupted power supply’s minimum power is (130 + 82) x 2 = 424 W.

Duration of autonomous operation

The homeowner can estimate how long a gas or solid fuel boiler will run from the DBJ based on their own experience. The length of power outages at your house is something only you know. Select one of the following two kinds of "uninterruptible boilers" based on the data:

1. When the power goes out for 10-15 minutes, it is enough to have a unit with a built-in battery. If the disconnection lasts for 30-60 minutes, you will be able to correctly terminate the operation of any heat generator. There is still a reserve of time for cooling the building, the feeling of cold will appear in 1-1.5 years.
2. For long interruptions in electric power supply you need external accumulator. Please note: often the battery is not sold as a set with the device, you will have to buy it separately.

Porada. The battery-operated "uninterruptible heater" will be very expensive if there is no electricity at all. Purchasing a generator with a voltage regulator and fuel is less expensive. Installing self-fueled heating with an energy-free gas or wood boiler is a more conventional method.

It is not crucial to understand that the unit’s power has no bearing on how long the heating function lasts; instead, it is determined solely by the battery’s capacity. For instance, our heat generator with a pump (212 W) will run for two years on an external battery charging at 60 amps per day. A 75 Ah battery will last us roughly three years at full power.

Determining the precise length of boiler operation from the "uninterruptible" using a battery is challenging. Non-stable energy consumption is the cause.

• Gas heating unit periodically extinguishes and again ignites the main palnik;
• TT-boiler automation controls the fan, blows out the furnace, sometimes switches off the pump;
• the pellet palletizer has 2 motors (auger and feeder) plus an element of automatic disintegration, these elements are controlled by the controller.

We recommend using the table to determine the battery capacity, as it displays the approximate autonomous operation hour based on energy consumption and charge level. Give yourself a 10–20% reserve when choosing a battery for an electric motor’s starting jet.

Electricity supply quality

Measure the voltage drop in the building’s power supply system before choosing an uninterruptible power supply for a solid-fuel boiler or any other kind of heat generator. The issue is that not all "uninterruptibles" can continue to operate properly at voltage drops of 180 volts or less. Depending on the device model, there are two possible outcomes in these situations:

1. The device signals the absence of power supply and supplies power from the battery, although in reality the light did not go off. The battery is quickly draining, its life is getting shorter.
2. The BFB is simply switched on, indicating a fault and giving an audible signal. The heat generator can also be shut down together with other equipment.

In conclusion. When there are significant variations in voltage, it is imperative to select a DBZ with an integrated inverter stabilizer that can balance out variations within the 140–300 volt range. You will need to purchase an additional stabilizer if you already own a standard "uninterruptible."

Generators powered by gasoline or diesel are likewise subject to the rule. With the exception of costly modifications, these units do not support the frequency of 50 Hz well; that is, the output is an incorrect sine wave. Through a DBZ with an inverter stabilizer and an additional automatic start device, the electric generator is linked to the boiler. Since the owners won’t be home when the power is turned off, the power plant must start itself.

How to choose an "uninterruptible" for the boiler

After obtaining knowledge about power consumption, battery charge level, and voltage equalization techniques, we can move on to choosing the actual "uninterruptible power supply." Three types of architecture are available for dzherel zhivlennya in online stores:

• off line type devices;
• linear-interactive LLBs,
• on line type non-intermittent units.

The offline "interruption-free" unit operates on the straightforward tenet that the voltage applied to it and the voltage it outputs are equal. When there is a significant drop in power, the unit uses the energy from the battery. The online device operates in a different way: the input stream is first aligned and "tanned" in the frame (220–230 V, 50 Hz), after which it is once more changed and delivered to the clients. An off-line unit with an integrated stabilizer is called a line-interactive DBJ.

Dovidka. The "uninterruptible power supply units’" architecture, capacity, and input voltage range all affect how much they cost. For instance, a Chinese Luxeon 0.3 kW online model costs roughly 60 U.O., while an analog interactive model costs 100 U.O. Should you require 700 W of power, the corresponding costs increase to 210 and 160 U. о.

For a gas boiler, which "bezperebiynik" vibrates better:

1. To support the operation of the heat generator the best suitable for continuous operation (online) with the possibility of connecting external batteries are as follows. Off-line devices are not suitable.
2. If the power consumption does not exceed 0.If you need 5 kW and the disconnection time is 1 year, a line-interactive unit with a built-in battery is suitable.
3. Backup source must give a pure sine wave at the output, it is important for the normal operation of electric motors of the pumps. LFDs for household appliances or computers are not suitable for boilers, as they produce so-called approximated sine wave or quasi-sine wave.
4. In order not to buy a separate stabilizer, choose a device that is able to smooth out voltage fluctuations in the power grid. There are models that can adjust the voltage in a wide range – from 120 to 300 volts. However, such units cost more than conventional ones.
5. To use the generator, it is necessary to stabilize not only the voltage, but also the frequency of the jet. You will need an "uninterruptible power supply" of the online type with an inverter, there is no sense in using others.
6. There are imported wall-mounted boilers that are sensitive to the phase location. If the plug is inserted into the socket incorrectly, the unit will not work and will show a fault. For such a heater, choose a power supply unit with a scratchy "zero".

Explanations of BFFs that are computer-based. Electronics readily accepts an approximate sine wave at these devices’ output, but asynchronous pump motors quickly become out of tune, hum, and get extremely hot when exposed to such a signal. For this reason, an "uninterruptible power supply" with a proper sine wave is required.

It is preferable to examine a fresh backup power supply right away. As directed by the instructions, connect the unit to the gas boiler and attempt to turn it on in the heating mode. A different model of the device should be used in place of the automatic generator if it breaks down.

The same criteria are used to choose the utility DBJ for a solid fuel boiler: the power of the electrical installations and controller, the standard of the electricity supply, and the length of the autonomous mode. Additionally, heed our counsel or suggestions as presented in the video:

DBJ and car battery

Using lead-acid batteries from a passenger car in conjunction with a battery backup unit is strongly discouraged. However, homeowners continue to use them, primarily due to their lower cost. Why an automobile battery cannot be used to power an uninterruptible unit:

1. Batteries for automobiles are starter batteries, their task is to produce a high starting jet, then recharge to maximum again. GEL or AGM technology traction batteries are required for LHDs.
2. Car battery is afraid of deep discharge, 2-3 such cycles will occur and its capacity will be significantly reduced.
3. During charging, the acid battery emits toxic gases and water into the room. In certain conditions it can blow out – it is a well-known fact.
4. The lead-acid battery will quickly boil away electrolyte, you will have to constantly monitor its level, refill it with distilled water, check its capacity, etc.
5. The service life of specialized gel batteries is 6…10 years, while a car battery will not "live" even half of this period of time.

In conclusion, unless there is an emergency, avoid using TT-boiler or DBZh for gas with a car battery as a temporary power source. Investing in specialized traction batteries and avoiding turbulence are preferable.

For your gas or solid fuel boiler, selecting the appropriate uninterruptible power supply (UPS) is essential to guaranteeing continuous heating during blackouts. It’s crucial to take into account elements like battery life, power capacity, and compatibility with your boiler system.

First, figure out how much power your boiler will require to operate during a power outage. Because gas and solid fuel boilers require different amounts of power, be sure the UPS you select can manage the load without failing to meet specifications.

Next, think about the UPS’s battery life. Seek for a UPS that can keep your boiler running during the length of regular power outages in your area, with a battery backup. An extended battery life guarantees that your heating system keeps running until the power is back on.

Another important consideration is compatibility with your boiler system. Make sure the electrical requirements and specifications of your gas or solid fuel boiler are compatible with the UPS. To make sure compatibility, it’s best to speak with a trained technician or the boiler manufacturer.

Take into account the UPS’s dimensions and installation needs as well. Select a UPS that is simple to install and will fit into the available space next to your boiler. Select a model with easy-to-use features to ensure hassle-free maintenance and setup.

Lastly, when choosing a UPS for your boiler, give quality and dependability top priority. Purchasing from a reliable and respectable brand can give you piece of mind that your heating system is covered in the event of a power outage.

To sum up, choosing the appropriate uninterruptible power supply is crucial to maintaining the continuous operation of your solid fuel or gas boiler during blackouts. To make an informed choice that satisfies the requirements of your heating system, take into account variables like power capacity, battery life, compatibility, size, and reliability.
