Wijas is a Polish manufacturer specializing in compact, instantaneous electric water heaters, known for their "Perfect" series. Their product categories are defined by their application, power output, and physical design, focusing on efficiency and space-saving solutions for point-of-use hot water.

Here is a breakdown of their primary product categories:

1. Instantaneous Electric Water Heaters (The "Perfect" Series)

This is Wijas's flagship product line, designed to provide hot water on demand for single outlets. The key characteristic of these heaters is their small size, making them suitable for installation in tight spaces, such as under sinks or inside cabinets.

  • Key Features:
    • Compact Design: The heaters are noted for being among the smallest on the market, with dimensions that allow them to be easily hidden from view.
    • Energy Efficiency: These units heat water as it flows through, only consuming electricity when hot water is being used. Many models are rated with a high energy efficiency class, such as 'A'.
    • Electronic Control: They feature an electronic switching system that is more reliable and durable than traditional mechanical switches.
    • Power Output Options: Available in a range of power outputs (e.g., 3.5 kW, 4.5 kW, 5.5 kW) to suit different needs and applications.
    • Application-Specific Models:
      • Undersink/Below Sink Models: These are designed for single-point use at a washbasin or kitchen sink. They are non-vented heaters that can be connected to standard taps.
      • Shower Models: Wijas also offers higher-powered instantaneous heaters (e.g., 7kW to 9kW, often for 400V systems) that can be used to supply a shower with hot water, sometimes with a manufacturer-recommended shower set.

2. Instantaneous Water Heaters with Integrated Tap

Some Wijas models, particularly those for washbasins and sinks, come with a solid brass tap integrated into the unit.

  • Key Features:
    • All-in-One Solution: The combined tap and heater unit provides a simple and clean installation.
    • Temperature Regulation: The integrated tap often includes a valve for adjusting the water temperature, offering greater user control.
    • Self-Cleaning Aerator: A feature on some models designed to prevent limescale buildup and maintain a consistent water flow.

3. High-Power Instantaneous Water Heaters

For applications requiring higher hot water output, Wijas manufactures models with greater power ratings, often intended for 400V power supplies.

  • Key Features:
    • Higher Flow Rate: These units can heat a larger volume of water, making them suitable for multi-point use or for running a shower.
    • Specialized Models: Product lines like the "POW LCD MULTI" series are designed for more demanding applications.

FAQs

  • What is the difference between an instantaneous water heater and a traditional water heater?

    An instantaneous water heater, like those made by Wijas, heats water as it flows through the unit. It only uses energy when you turn on the hot water tap. A traditional (storage) water heater, on the other hand, keeps a large tank of water hot at all times, consuming energy even when no hot water is being used. Wijas heaters are ideal for point-of-use applications where you need hot water quickly and want to save energy by not heating a full tank.

  • How do I choose the right power output (kW) for my Wijas water heater?

    The power output you need depends on two main factors: the temperature of the incoming cold water and the desired flow rate. A higher kW rating will heat the water faster and to a higher temperature. For a simple hand washbasin, a 3.5 kW or 4.5 kW unit is often sufficient. For a kitchen sink where a stronger flow is needed, a 5.5 kW or higher model might be more appropriate. In colder climates, or for a shower, a higher power output (e.g., 7 kW or 9 kW) is typically required to achieve a comfortable temperature.

  • What kind of taps can I use with a Wijas instantaneous water heater?

    Wijas heaters are non-vented (pressure-type) heaters, meaning they can be used with standard taps and mixers. However, it's important to use a tap that is suitable for hot and cold water supplies. For best results, it's recommended to install a tap with a flow aerator to maintain consistent water pressure and reduce splashing. Some Wijas models come with a solid brass tap integrated into the unit, offering a complete, ready-to-install solution.

  • Can I install a Wijas water heater myself?

    While Wijas heaters are designed to be compact and easy to install, it is strongly recommended that the installation be carried out by a qualified electrician or plumber. This is crucial for safety and to ensure the unit is connected correctly to the appropriate electrical supply. Incorrect installation can pose a risk of electric shock and may also void the product's warranty.

  • How does the electronic switching system work and is it better than a mechanical one?

    Wijas's electronic switching system is a key feature of their "Perfect" series heaters. It uses a high-speed electronic circuit to activate the heating element, rather than a physical mechanical switch that can wear out over time. This system is more durable, reliable, and precise, leading to more consistent performance and a longer product lifespan. It also enables features like a smoother temperature curve and better energy management compared to older, mechanically switched models.
