Collection: DeXpro

8 products

DeXpro is a brand specialising in electric water heating solutions, primarily for commercial and light industrial applications, though their products are also suitable for residential use. Their focus is on providing compact, energy-efficient units for point-of-use hot water.

Delux Digital Inline Instantaneous Water Heaters

This is one of DeXpro's core product lines. These are tankless, on-demand water heaters designed to be installed inline with a water supply. They heat water as it flows, eliminating the need for a storage tank and reducing standby heat loss.

Power Outputs: Available in various power ratings, such as 3.5kW, 5.5kW, 7.5kW, and 9.5kW, allowing for selection based on the specific hot water demand.

Key Features:

  • Compact and Stylish Design: Slimline units designed to be discreetly installed under sinks or in small spaces.

  • Digital Control: Feature a digital temperature display and touch controls for accurate and easy temperature setting.

  • Energy Efficiency: As instantaneous heaters, they only consume energy when hot water is being drawn. They often have an A-rated energy efficiency.

  • Application: Ideal for hand washing in commercial settings like offices, shops, factories, and schools. Higher-powered models can also be used for multiple basins or even a single shower in some cases.

  • Installation: Can be installed in any orientation and are supplied with pre-wired cables. They are recommended for use with spray head taps to optimize performance.

Delux Unvented & Vented Storage Water Heaters

DeXpro also offers a range of small storage-type water heaters with insulated tanks. These heaters maintain a pre-heated volume of water for immediate use and are suitable for applications where a slightly larger volume of hot water is needed consistently at a single point.

Vented vs. Unvented:

  • Vented: These units are typically installed over or under a sink and come with a specific vented tap. They operate at low pressure.

  • Unvented: These heaters can be connected directly to the mains water supply and operate under mains pressure. They often require additional accessories like an expansion vessel and pressure-reducing valve.

Capacities: Available in various tank sizes, such as 5, 6, 10, and 15 litres, each suited for different applications (e.g., a single basin vs. multiple basins).

Key Features:

  • Rapid Heat-Up: Equipped with a 2kW element for fast heating.

  • Durable Construction: Tanks often feature a blue diamond enamel coating for rust and corrosion resistance and dense CFC-free insulation to maintain water temperature for extended periods.

  • Safety: Includes features like a manual re-set thermal cut-out and frost protection settings.

  • Digital Display: Many models have a digital display for temperature control.

FAQs

  • What is the main difference between Dexpro's instantaneous and storage water heaters?

    The main difference is how they heat water. Dexpro's instantaneous water heaters (like the Delux Digital Inline series) are tankless and heat water on demand as it flows through the unit. This makes them highly energy-efficient as there is no standby heat loss. Dexpro's storage water heaters, on the other hand, have an insulated tank that holds and pre-heats a specific volume of water, keeping it ready for use. Instantaneous heaters are best for single, low-demand outlets, while storage heaters are better for higher-demand applications or where multiple outlets might need hot water at the same time.

  • How do I choose the correct power rating (kW) for an instantaneous water heater?

    The power rating you need depends on the flow rate and the desired temperature rise. A higher kW rating allows for a higher flow rate while maintaining a hot water temperature. For a single hand washbasin in a commercial setting, a 3.5kW or 5.5kW unit is often sufficient. For applications with a greater flow requirement, such as a shower or a kitchen sink, a 7.5kW or 9.5kW model may be necessary, especially in colder climates where incoming water temperatures are lower.

  • Do I need an expansion vessel for my Dexpro water heater?

    This depends on the model. Dexpro's instantaneous water heaters do not require an expansion vessel. However, for their unvented storage water heaters, an expansion vessel is a necessary component for safe operation. These unvented systems operate under mains pressure, and the expansion vessel accommodates the expansion of water as it is heated, preventing a dangerous build up of pressure.

  • Can I use a Dexpro water heater with a standard tap?

    Yes, most Dexpro water heaters can be used with standard taps. However, for their instantaneous models, it is strongly recommended to use a flow-restricted or spray head tap nozzle. This is because the water temperature output is directly related to the flow rate—a restricted flow ensures the water stays in contact with the heating element for longer, resulting in a hotter and more consistent temperature.

  • What should I do if my instantaneous water heater is not providing hot enough water?

    If your Dexpro instantaneous water heater is not producing sufficiently hot water, there are several things to check. First, ensure the water flow rate is not too high. You may need to reduce the flow at the tap to allow the unit to heat the water to the desired temperature. If the issue persists, check for any error codes on the digital display, as this may indicate a problem with the heating element, a blocked inlet filter, or a sensor issue. In hard water areas, regular cleaning of the inline filter is also recommended. If the problem continues, it's best to consult a qualified electrician or plumber.
