Frequently Asked Questions

We work to provide the best heating solutions with our commitment to customer satisfaction and quality.

What is a double-coil water heater and how does it work?

A double-coil water heater is a hot water storage device that contains two separate heating coils for heating water. The coils transfer heat from different energy sources (e.g., solar energy and a boiler) to the water. It generally operates as follows:

  • The first coil is typically used to store hot water from the solar energy system.
    The second coil provides additional heating from an auxiliary energy source (natural gas boiler, electric heater, etc.) when needed.

This ensures that hot water is continuously available and energy efficiency is increased.

What are the advantages of double-coil water heaters?

  • Multiple energy source usage: Can receive energy from two different sources simultaneously (e.g., solar energy and boiler)..
  • Energy efficiency: Maximizes benefit from renewable sources such as solar energy..
  • Backup system: The second source activates when the main source is insufficient..
  • Faster heating: Water heats more quickly thanks to the two coils..
  • Continuous hot water: Meets hot water demand without interruption.

In which areas are double-coil water heaters used?

This type of water heater is typically preferred in areas with high hot water demand:

  • Residences (especially with solar energy systems).
  • Hotels and resorts.
  • Gyms.
  • Swimming pools.
  • Hospitals.
  • Industrial facilities

How is energy efficiency achieved?

  • The first coil provides low-cost heating using a renewable energy source (typically solar energy)..
  • The second coil only activates when needed, preventing excessive energy consumption..
  • Good insulation of the tank prevents heat loss from the stored hot water..
  • Optimized operation can be achieved with automation and timer systems.

What are the maintenance and safety precautions?

Maintenance:

  • The coils should be regularly cleaned to prevent limescale and blockages..
  • The water tank and connection points should be inspected at least once a year..
  • Periodic maintenance of the water circulation pumps should be performed.

Safety:

  • Over-temperature and pressure protection systems are installed..
  • Thermostats and pressure valves should be regularly checked..
  • Automatic shutdown and alarm systems ensure temperature control.

How is the capacity of a double-coil water heater determined?

The following criteria should be considered when selecting capacity:

  • Size of the usage area.
  • Daily hot water demand.
  • Capacity of the solar energy system (if used).
  • Power of the backup heat source

A hot water demand analysis carried out by an expert is usually required to determine the most accurate capacity. For example:

  • 150-200 liters for small houses.
  • 300-500 liters for medium-sized houses.
  • 1000 liters and above for commercial use

    What is a Double-Coil Water Heater?

    These water heaters, named for containing more than one heat source, are functional systems used to produce hot water. They come in various power capacities and tank volumes, and their suitable applications may vary. Double-coil water heaters, which allow simultaneous use of two different energy sources, may have different water heating times.

    By considering your needs, you can select the right product and make your production processes more practical. These products, which resist wear, perforation, tearing, and scratching, help store water hygienically. Double-coil water heaters, which reduce your energy costs in the long term, allow you to save on operational expenses.

    How Do Double-Coil Water Heaters Work?

    Double-coil water heaters, which can be installed easily, are also very simple to use. Once the energy and water connections are made, the unit can be activated with a single button. The two coils inside circulate hot water from different sources, enabling heat transfer. The lower coil is typically connected to a solar energy system, while the upper coil is linked to an additional source such as a boiler or combi. The heat sources operate sequentially or simultaneously to heat the stored water.

    Thanks to its insulated design, the water heater maintains the water temperature for a long time. Its thermostat controls the temperature and activates the heat sources when necessary. With regular maintenance, these water heaters can preserve their original quality for many years. You can rely on double-coil water heaters in activities where a continuous supply of hot water is needed.

    Features of Double-Coil Water Heaters

    High-quality double-coil water heaters can heat water up to 70°C. These products can tolerate a pressure level of 8 bar, support 18 bar in the heating fluid circuit, and 1 bar for steam. Both the upper and lower coils can raise the water temperature with minimal heat loss. Water heaters with different capacities and diameters may have varying insulation materials. Insulation is provided with rigid or soft polyurethane foam, making these products suitable for use in all seasons.

    Where Are Double-Coil Water Heaters Used?

    Double-coil water heaters are commonly found in areas with high hot water demand. The main examples of areas where double-coil water heaters are used are as follows:

    • Different Types of Residences: These water heaters can be used in both urban and rural homes. They are also suitable for seasonal homes, summer houses, or highland cottages that are used only during certain times of the year.
      Shared Use Areas: Hot water needs in schools, hospitals, airports, student dormitories, or gyms can be met with water heaters. Selection can be made from water heaters with different capacities, considering the number of people using these spaces.
      Industrial Areas: If you need to heat water for production in factories, workshops, or construction sites, double-coil water heaters can be an ideal choice. These products provide uninterrupted hot water for hours, making manufacturing processes more practical.

    Double-Coil Water Heater Models for Different Budgets

    The prices of the water heaters in our category may vary depending on their technical specifications. For example, increases in capacity and power directly affect the price. Similarly, the type of insulation also influences the cost. You can select a water heater based on your intended use and environmental conditions. Water heaters designed by Aktes Isı’s expert engineers and produced by its experienced team can be used in both residential and workspaces.
