Long-term cost savings and a lower carbon footprint are two benefits of a high-efficiency boiler.

A heating system must have both durability and reliability. Since a gas boiler is an expensive purchase, you want to be certain that it will continue to function well for many years to come. Through an assessment of each boiler’s dependability and construction quality, we will assist you in choosing a model that provides dependable performance and peace of mind, even in the coldest months of the year.

Why a floor standing gas boiler is better than a wall mounted boiler

Even though the decision should only be made by the individual, a general analysis indicates that the floor-type unit will work better. Cottages or private homes in the country frequently have these kinds of designs.

Additionally, wall-mounted models are installed in apartments; this is not a characteristic, but rather a result of the limited amount of open space and external attractiveness. It is safe to say that the following are advantages of the floor boiler:

  1. Good performance.
  2. Long service life.
  3. Quality, thick-walled parts.
  4. Energy independence.

Because wall-mounted units are frequently the target of voltage fluctuations-related malfunctions, the manufacturer makes every effort to keep the product’s weight as low as possible.

This has an impact on the components’ quality; they are unable to boast a long service life, and this type of two-circuit boiler requires more time to adjust; the procedure is appropriately referred to as drawn out.

We evaluate the top heating and insulation choices for floor-standing two-circuit gas boilers in our evaluation. Keeping your house at a comfortable temperature requires these boilers. We consider things like cost-effectiveness, longevity, ease of use, and efficiency. Our goal is to give you accurate and unbiased information so you can choose a floor-standing, two-circuit gas boiler for your house with confidence.

Device and operating principle

There are no significant distinctions between the types other than the stronger assemblies and key parts. The primary components are as follows:

  1. First heat exchanger.
  2. Burner.
  3. Second heat exchanger.
  4. Pump for circulation.
  5. Turbocharging.
  6. Control panel.

The coolant is heated in accordance with the predetermined parameters, enters the heating system, and then exits through the return line to begin the next cycle. In order to bring the fluid in the secondary unit to operating temperature, the water in the first heat exchanger loses some of its heat as it exits.

The three-way valve allows the coolant to be combined with the cooled water and heated to the proper temperature before being transferred to the main line. The chimney is used to remove the byproducts of gas combustion; some models have turbo fans and natural drafts.

Rules for choosing a gas two-circuit floor standing boiler

Although the unit’s power is a crucial deciding factor, many other features should also be taken into consideration. These include:

  1. How much gas is consumed.
  2. EFFICIENCY.
  3. Performance of the circuit responsible for hot water.
  4. If the equipment is energy-dependent, you need to find out the electricity consumption.
  5. Maximum temperatures.
  6. System pressure.

It is feasible to identify the proper copy of the numerous brands that are displayed with the help of a thorough analysis of the technique. It will be possible to distinguish notable drawbacks and benefits by comparing the features; however, it is also crucial to consider the availability of prompt service as well as the opinion of repair and maintenance services.

Convection or condensing

Equipment that uses convection cannot be referred to as being maximally productive because some of the heat generated during coolant heating just escapes into space. These units frequently have an efficiency index of 85%; real productivity is rarely higher than these numbers.

Advantages include obviousness, affordability, ease of installation, compact size, and simple design. Condensing types of gas two-circuit floor apparatuses are superior; they use steam energy to heat the liquid, making them at least 20% more efficient. This is because an additional heat exchanger is installed. They will be more expensive, but the costs will soon be covered, the gas is used sparingly, and the efficiency is very high.

Energy-dependent or non-volatile

Since the building owner will also be responsible for paying for the electricity used, installing the network-operated device is not the most profitable option. As a result, the majority of buyers choose these A-class units++.

It is impossible to ignore the high cost of replacement parts, maintenance, and automated systems because malfunctions can occur at the most inconvenient times. It is accurate to refer to a common occurrence as board failure; replacing the board will cost half as much as purchasing new equipment, and repairs are also expensive.

Energy-independent versions operate similarly to gas stoves, heating the tank through liquid, with minimal voltage fluctuations and minimal disconnections due to the independent operation of the two-circuit gas boiler.

Since the coolant circulates naturally, it is necessary to plan ahead for the placement of heating devices.

Open or closed combustion chamber

The most economical equipment has an open combustion chamber, which allows gas combustion to produce an efficiency index of 109% and air intake. The set comes with two burners: a main burner and a second pilot burner. The burner controls the main component’s intensity, while the pilot element operates continuously.

Appliances featuring a closed combustion chamber are less useful since they require a forced draft to function. This component allows for the intake of fresh air. This design technique is frequently utilized in apartments, where it is built into a single furniture ensemble or mounted with a special box.

Optimal gas consumption

A comparison of multiple models with the same capacity can be used to determine the minimum figure. You will need to know the appliance’s efficiency as well as the fuel’s calorific value in order to determine how much gas is used for every 1 kW. Considering the standard norms, the mixture’s data in a typical main is 9.3 kW/cubic meter. м. One kW will be generated in 0.12 cubic meters if the unit coefficient is 90%. This is calculated as follows: 9.3×90%, followed by 1/8.37.

The required capacity for floor standing double-circuit gas boilers

This is one of the most significant indicators; every customer who purchases a device in the store looks at the device’s passport data. It is not advisable to buy equipment that is too powerful because it will use a lot of fuel and strain the family’s finances.

If it is insufficient, maintaining a comfortable temperature will be impossible, or else the equipment will operate continuously on the verge of failure.

There is a standard calculation method that entails multiplying the specific power by the building’s square footage, which is determined for every part of the nation, and dividing the result by 10. 200 м. sq. ̅ 1.1 kW/10 = 22 kW is an example. I consider the strip in the middle.

This is how the data by climate zone is presented:

  1. South: 0.7-0.9 kW.
  2. Middle band: 1,0-1.2 kW.
  3. Moscow Region: 1.2-1.5 kW.
  4. Northern: 1.5-20 kW.

Corrections must be made for the most accurate calculation, taking into account the unique characteristics of the premises.

Heat exchanger

It won’t be necessary to provide protection against system freezing if the private building is outside of the city or is a cottage where occupants do not intend to live long-term.

Antifreeze is the most popular liquid; after figuring out how many liters it is, it should be added to the main line. At lower temperatures, these substances stop the water from solidifying; instead, it transforms into a gel-like state, maintaining the integrity of all pipes and connections.

Storage tank

Continuous operation of heating and domestic hot water (DHW) can be achieved with floor-mounted, two-circuit boilers that have an integrated tank, particularly when large volumes of the liquid are anticipated. Equipment with flow-through capabilities cannot claim such technical features.

The tank has a capacity of 25 to 60 liters, and the power is chosen with operational requirements in mind. Because some of the heat is used to warm the water, the built-in element helps to reduce temperature fluctuations in the main heating system.

Smoke extraction process

To cut expenses, you can connect to the building’s existing chimney if one exists. There are a number of ways to realize the intended hole in the wall or ceiling, but it’s crucial to make sure the parts are assembled correctly to prevent different excesses from happening.

The boiler room must be equipped in compliance with all regulations, the mechanism of action will need a separate room for installation, and most owners add forced fans to increase the effect.

EFFICIENCY

These details are located in the device’s passport; comfort levels within the building and blue fuel savings determine how effective the system is. Although many people believe that the more the indicator, the more efficiently the device will operate—a belief that is not supported by reality—I nevertheless suggest paying attention to these features. The best boiler types for heating a private home in this indicator are condensing models, whose data are frequently 98% and higher.
