Why HephaHeat?

HephaHeat brings real benefits to water heating systems because of its method of operation. The tables below show performance for delivery volume and a comparison between device size and the high volume of hot water produced.

100°C systems

Instant boiling water systems have grown in popularity in recent years, with many providers offering similar systems.

Using our technology a typical 5L unit will be four times smaller and yet still supply the same quantity of water, while out performing current systems in the area of re-heat time, cups per hour and standing losses.

• Delivery volume up to 4:1 – hot water to device size (see graph)
• Fast recovery time – start to draw off water within 20% of recharge time
• Install at point of use – units can be installed directly where needed
• HephaHeat units connect directly to a standard single phase mains 13 Amp spur

60°C Systems

Cylinders used to supply substantial amounts of hot water are typically large and occupy precious space within most domestic environments. A HephaHeat device will supply 300L of water at 60°C and yet is sized at 35L providing valuable extra space. The charge rate and times can be decided at the design stage and the units benefit from the same low levels of standing loss as the entire family of HephaHeat systems. Water scaling is not an issue as the high temperature operation ensures that lime scale does not build up on the heating element.

• Delivery volume up to 8:1 – hot water to device size (see graphs)
• Fast recovery time – start to draw off water within 20% of recharge time
• Charge at night electricity rates
• User selected flow rate up to 15L/min
• No limescale build-up

38°C Systems

Tanked or instantaneous 38°C water systems typically located above or below sinks or used for showering can see improvements using HephaHeat technology. A HephaHeat device of 0.30L can supply 5L of hot water in a single draw.

• Delivery volume up to 17:1 – hot water to device size (see graph)
• Fast recovery time – start to draw off water within 20% of recharge time
• Charge at night electricity rates
• Ultra small device size
• No limescale build-up

Charge and recharge time

While the primary driver behind the charge and recharge time of a HephaHeat unit is determined by unit size and the type of insulation used, the reduced volume and surface area of a HephaHeat unit allows for the use of more advanced insulation materials and techniques than would normally be commercially viable in equivalent tanked systems.

Electrical rating can be varied to allow product specific designs, with 1.8 – 3kW being the rating normally chosen to balance power draw and recharge time.

In addition to the benefit of a fast charge and recharge time, HephaHeat units do no need to be fully charged in order to deliver water at the required temperature. Typically this can start to be drawn at 20% of the nominal charge time of a given device.
