The principle of operation of a storage gas boiler
- There are several different types of water heaters. Despite the difference in the design, all gas boilers of capacitive type are distinguished by the same principle of operation. Water heating is carried out as follows:
Camera Camera – at the bottom of the case is a burner with forced or natural thrust. When burning gas, heat is released. Unlike the running speakers, the burner is not in contact with the heat exchanger directly. The task of the combustion chamber to generate heat and direct it to the frying pipe. - Heat exchanger – there are no radiators familiar to running water heaters in the boiler. The heat released during gas burning is sent to the frying pipe. The walls of the heated pipe are in contact with water. Heat exchange occurs.
- Water supply to the consumer – the heated liquid remains in the heat -insulated capacity. The water heater automatically maintains the temperature. When opening the water supply tap, the pressure of hot water is created, as in an ordinary boiler, by displacing it with a liquid from the CVS. Hot water is instantly supplied to the consumer.
The initial heating takes place in 20 to 30 minutes. Following that, the boiler keeps the required, comfortable temperature while using the least amount of gas possible. The internal device includes multiple sensors (gas pressure, water, traction), automation, and a mechanism to prevent calcium deposits (magnesium anode). For domestic use, accumulative containers range in capacity from 80 to 200 liters.
When it comes to choosing a gas water heater for your home, opting for a cumulative type can be a smart move. These heaters store hot water in a tank, ensuring a steady supply when you need it. The main thesis is that selecting the right one involves considering factors like capacity, efficiency, and safety features. Capacity matters because you want a heater that can meet your household"s hot water needs without running out too quickly. Efficiency is crucial for saving energy and lowering utility bills, so look for models with high Energy Factor (EF) ratings. Additionally, prioritize safety features like automatic shut-off valves and proper ventilation to prevent accidents and ensure peace of mind. By carefully weighing these factors, you can find a gas water heater that keeps your home comfortably supplied with hot water while being efficient and safe to use.
How to choose a gas boiler of a cumulative type
On the market for gas watering equipment, boiler models come in several dozen varieties. Experts advise considering a few technical features when making a decision:
- Type of tank – how to correctly calculate the volume of the accumulative container is explained below. In addition to calculations, you need to decide on the choice of tank material. Manufacturers make tanks from the following types of metal:
- From stainless steel – optimal material, characterized by long -term operation, resistance to corrosion. The only drawback: high cost. Stainless steel has several classes. For the drive, you can use only a special food stainless steel.
- With enameled tank – there are several types of coating. Previously, the boiler tank was protected with the help of ordinary enamel, which was covered with dishes. Cheap models of water heaters still use this type of protection. Disadvantages: susceptibility to mechanical damage and thermal effects. The service life even with care does not exceed 5 years.
- Glass -ceramic coating – modified enamel with good strength characteristics and heat resistance. Glass ceramics are distinguished by a longer service life, up to 7-8 years of service.
- With titanium spraying – according to characteristics, boilers are similar to those made of stainless steel. The tank of capacitive boiler will freely work out for at least 10 years, while the intensity of water heating does not affect durability (as in the case of ordinary enamel coating).
- Atmospheric gas boilers – take air from the boiler room, using natural circulation.
- Turned storage water heaters with a closed combustion chamber – oxygen supply is carried out from the street (models with a coaxial chimney) or from the room, forcedly. Turbo boilers are economical. Disadvantages: noise during inclusion, energy -dependent. Type of ignition – not all water heaters work the same. By the principle of inclusion, two main types of drives are distinguished:
- Automatic ignition – works on batteries or from the network. Inclusion occurs when the water temperature decreases below the specified parameters. Water heaters with an electronic ignition system operate in fully automatic mode. The consumer only needs to set the heating temperature.
- Piezoroszhig – in this case, a constantly working wick is provided inside the water heater. The ignition is performed manually. The fiber of the fiber is set on fire by a piezoelent. The wick works constantly and lights the main burner.
- The principle of installation – the design of the drives is made in two solutions. The first are designed for flooring. The volume of accumulative capacity is practically not limited. Water heaters for wall installation are limited in volume. The maximum capacity, as a rule, does not exceed 100 liters.
They calculate the volume of a storage water heater after deciding on a storage capacity based on the five factors mentioned above. Independent calculation is possible.
How to calculate the volume
Limitations on the amount of hot water that can be supplied are the primary disadvantage of gas boilers. It’s already quite inconvenient that you have to wait for approximately thirty minutes to heat up more hot water after damaging the tank. You must determine the boiler tank’s volume accurately in order to minimize the stated drawback. Many details are considered when making calculations:
- the volume of the drive should be enough for comfortable washing and providing other needs in hot water;
- Excessive accommodation of the boiler leads to unnecessary gas costs when heating the hot water.
The first step in the calculations is figuring out how much hot water a private home or apartment actually needs. The cost of DHW is determined by water procedures. You can use the information in the table to determine the needs:
Action | The number of water used [l | Required water pressure [l/min | Temperature [° C |
bathing | 120 | 15 | 42 |
shower | 35 | 6.5 | 42 |
washing hands | 4 | 7 | 42 |
Washing | 9 | 7 | 42 |
shaving | 9 | 7 | 55 |
Washing dishes | thirty | 8 | 55 |
The information in the table is intended to supply one person with hot water in a private home or apartment using a gas storage water heater. With a few basic calculations, you can determine that a 60-liter capacity will suffice for two to three people’s hot water needs, and an 80-liter capacity for four people. Without a bath, the boiler’s capacity is shown.
Installing an 180-liter water heater is advised in order to completely guarantee hot water in a large home with multiple bathrooms. This will provide enough water for multiple family members to take showers simultaneously.
The following formula is used for precise calculations: volume = n x (t0 – t1): (t2 – t1). N stands for water consumption, t0 for the needed heating temperature, T1 for cold water, and t2 for the boiler-submitted DHW intensity.
You can use specialized online calculators to minimize the amount of arithmetic calculations involved in the volume calculations.
