How to choose a softener of water for a gas boiler

A gas boiler in good working order is vital for maintaining a warm and cozy home. However, did you know that your water’s quality can have an impact on how well it functions? Due to the high concentrations of minerals in hard water, such as calcium and magnesium, your boiler may eventually become less efficient due to limescale buildup. Water softeners can help with that.

Selecting the appropriate water softener for your gas boiler is essential to preserving its lifespan and effectiveness. It can be difficult to choose the option that best fits your needs when there are so many on the market. But do not worry; we are here to guide you through the procedure.

It’s crucial to comprehend how water softeners operate and why your boiler needs them before getting too technical. Water softeners are essentially appliances made to take minerals out of hard water in order to keep limescale buildup at bay and increase the lifespan of your boiler. Long-term energy bill savings and increased heating system efficiency are two benefits of installing a water softener.

There are a few things to take into account when choosing a water softener for your gas boiler. First, you’ll need to figure out how big of a softener you need based on your area’s water hardness level and your boiler’s flow rate. Furthermore, take into account the kind of regeneration system, including demand-, meter-, or time-triggered systems, as these will affect the softener’s upkeep needs and efficiency.

How to understand that water in the heating system requires softening

Surface-sourced water, even if it’s not the purest available, will always be hard, so it must be softened before using it in a gas boiler for heating. Here are some easy examples to confirm this: lime plaque on a tap, or scale in a kettle.

You can buy test strips to measure the water’s stiffness if you want to be absolutely certain and make sure the well water is clean. They are offered for sale in establishments that have pet stores, branded home appliances, or coffee makers. These are reagent-coated paper strips that need to be submerged in water so that their color can be compared to "palette results."

The current GOST 31865-2012 states that the degree of stiffness, or ° F, is the unit of measurement for water hardness:

• up to 2 ° V – soft;
• from 2 to 10 ° V – medium stiffness;
• more than 10 ° V – extremely stiff.

In actuality, 4-5 °F already have a role in scale formation and settlement on salt walls. With these and other results, a water softener—one of the filters below—is required to guarantee the gas boiler operates normally.

Types of filters softening water in the heating system

Polyphosphate

The cheapest, easiest, and most efficient choice. The polyphosphate (salt) filter’s apparatus is straightforward:

• Transparent container/sausage;
• plastic lid;
• drain;
• Crystals of polyphosphate salt.

As water flows through the polyphosphate salt crystals, it becomes saturated with sodium polyphosphates. This causes a film to form around the hard salts, counteracting their effects and shielding the system from deposits and scale. Water turns technical and unusable after going through an ion-income polyphosphate filter because polyphosphate is a toxic material.

Polyphosphate filters have a low service life due to their composition, which is dissolved polyphosphate salt crystals. Consumption of filler: three to five grams per thousand liters. If the volume of crystals has decreased two or more times, it is advised to completely alter the flask’s composition or the device assembly. In real life, this typically occurs six to eight months later. Replaceable crystal filters cost 150–400 rubles, while polyphosphate softening filters cost 300–1,200 rubles.

Magnetic

A more costly, yet highly efficient, small-sized filter. It is advised to use the water’s magnetic softener with gas boilers. The way it works is based on how magnetic field radiations change the composition of water:

1. Flowing through the filter, water for a short time changes its physical properties, as a result of which the crystallization process when heated occurs faster and in the volume of water, and not on the walls of the heating contour.
2. As a result of the transformation by a magnetic field, salts previously settled on the walls fall into the precipitate – a small crystalline sludge.
3. Sediment without harm to the system passes through the heating zone or boiling. It can also be completely stopped or displayed by a coarse cleaning filter.

Due to the short-term nature of the magnetic mitigation method, the filter needs to be installed as close as possible to the heat exchanger (the salt deposit and heating zone). Water that has passed through a magnetic phylldra-absorber retains its salt content and flavor without becoming technical.

Magnetic softeners have an almost infinite service life. The device costs between 1,200 and 3,000 rubles on average.

Electromagnetic

It is insufficient for the complete separation of salts from regular magnets at high coolant temperatures and flow rates. By applying an electric voltage and positioning a specific electrical winding on a magnet, one can increase the performance of a standard magnet. However, a standard magnetic filter will suffice to soften the water in a private home’s heating system.

Electromagnetic combination usage is only appropriate in industrial settings where coolant pressure and speed are high. Price range: $5,000–$20,000. rub.

Selecting the appropriate water softener for your gas boiler is essential to preserving its effectiveness and extending its life. There are a lot of options available, so it’s important to think about things like your budget, boiler size, and water hardness. In order to save expensive repairs and lower energy usage, a good water softener should efficiently remove minerals like calcium and magnesium that lead to scale buildup in your boiler. Aspects like salt efficiency, frequency of regeneration, and ease of installation and maintenance should be looked for. In the end, purchasing the appropriate water softener will safeguard your gas boiler and guarantee constant warmth and comfort in your house.

What else to pay attention to when choosing

Every softening filter for a particular kind of water works on the same basic principle; the only things that vary are the effectiveness and, less frequently, tiny aesthetic details. As a result, no specific selection criteria exist. Nonetheless, we advise being mindful of:

• performance – also throughput, measured in m 3 /h or l /hour;
• size – magnetic softeners slightly exceed the diameter of the pipe, while for polyphosphate filters, a lot of space around the pipe is required;
• thread diameter – must coincide with the diameter of the pipes used in the planned place of the installation;
• manufacturer – It is better to choose a filter of a well -known manufacturer, preferably in specialized retail outlets that can provide repair or replacement during the warranty period.

Connection to the heating system

You have the ability to install a softening filter on your own; household models typically have a 1/2-inch or, less frequently, a 3/4-inch diameter threaded connection. The filter is placed as close to the gas boiler’s inlet—that is, on the return—as feasible, but no closer than two meters. Prior to connecting, the polyphosphate filter needs to be cleaned to remove any potential tiny filler fractions. The actual installation procedure is easy to follow:

1. The seal is wound on the prepared threaded connection. It can be a sealing thread or a fum.
2. It remains to wind on the thread of the filter nut and tighten them well with the key.

We advise making sure the connection is tight before turning on the heating system completely. It is advised that the cutting valves be installed on both sides of the filter.

Alternative ways of softening

Water does not mix for many years in the majority of a private home’s individual heating systems. Consequently, fill up right away rather than continually softening water—which is reasonable but not always less expensive.

• distilled water (see the manufacturer"s recommendations in the instruction manual);
• already purified, soft and deserted water;
• Distributed water.

You should never mix acids, such as vinegar, with the coolant to clean or shield concentrates from scaling. These instruments are not intended for continuous use; rather, they are used to clean and flush the boiler’s and heating system’s heat exchanger.

Selecting the appropriate water softener for your gas boiler is crucial to preserving its effectiveness and extending its life. Softeners stop the formation of limescale, which can clog pipes and lessen heat transfer in your boiler, by lowering the mineral content of the water.

Think about things like the size of your home, the hardness of your water, and the kind of boiler you have when choosing a water softener. Selecting a softener that can handle the amount of water used in your home and the hardness of your water supply is essential.

Water softeners come in a variety of forms; these include salt-based, salt-free, magnetic, and electronic softeners. Minerals can be effectively removed from softeners made of salt, but replenishing the salt requires regular maintenance. Although they require less upkeep, salt-free solutions might not work as well in very hard water. While they might not offer the same level of scale prevention, magnetic or electronic softeners make the claim to change the way minerals behave in water.

Look into various brands and models before making a purchase to determine which one best suits your needs and price range. Gaining knowledge about the dependability and performance of different softeners can be facilitated by reading reviews left by other homeowners and speaking with an expert installer.

Once you’ve made your selection, make sure the water softener is installed properly and maintained in accordance with the manufacturer’s instructions. To keep the softener functioning properly, schedule routine maintenance, clean or replace the filters as needed, and regularly check the salt levels.

Purchasing a high-quality water softener for your gas boiler can reduce energy costs, avert expensive repairs, and increase the heating system’s lifespan. You can make an informed decision that will ultimately benefit your home and your budget by taking into account the unique requirements of your household and conducting in-depth research.
