Frequent Questions: Technology

What is the basic principle of Hoterway technology?

This technology combines the phase-shifting characteristics of a material, which changes state at about 45°C (from solid to liquid), with a heat exchanger with unique characteristics that accumulates heat at a constant temperature when the water inlet temperature is higher than 45°C. This accumulated heat is then released with substantially higher heat production when cold water passes through the equipment.

How does Hoterway technology works?

Hoterway is installed in the hot water distribution circuit in order to heat the stagnant water in the pipes until the hot water arrives from the equipment that heats the water. During the period in which cold water circulates through the heat exchanger, the material that was in the liquid state (at more than 45°c) is forced to change state while releasing the heat accumulated during the last use of the equipment. As it is a phase change process, heat release occurs at a constant temperature.

Where does the accumulated heat come from?

When hot water reaches the point of consumption (tap) the phase change of the material inside the equipment is reversed. As the hot water is at a temperature higher than the phase-changing temperature of the material, this will cause the material to return from the solid to the liquid state, also at a constant temperature. At this point the water entering the Hoterway is supplied at about 50°c, for example, and the Hoterway will release the water flow at 46°C. This difference in temperature is imperceptible to the customer, but it is enough to charge the device with heat for its next use.

Is Hoterway connected to electricity?

Hoterway has a thermal battery that is not connected to any power source, only uses the heat from the hot water flow to instantly heat the water from the pipes at the beginning of the next use of the equipment.

What is the life cycle of the batteries?

Heat accumulation/release is based on a stable and reversible physical phenomenon of a phase change material, so there is no thermal degradation of Hoterway batteries.

If the product is not used within 24 hours, how long does it take to reach the ideal temperature?

Hoterway has the ability to heat more than 14 L of water after use, with a high efficiency thermal insulation with very low losses. After 24h the heating capacity drops to 12L.

To determine the amount of time you can go without using it, you can do the bucket test to see how much water has to be heated. In most of the facilities already made by Hoterway, the product can go 3 days without use and the water will always come out hot.

Frequent Questions: Products

Are Hoterway shower columns compatible with any shower systems?

The ONE and HOTBOX shower columns are compatible with any type of shower systemas only with the exception of built-in showerheads. To install the Hoterway the user only has to have access to the hot and cold water connections on the wall to connect the flexible hoses to the column.

Can Hoterway shower columns be installed in showers and bathtubs?

Hoterway ONE and HOTBOX can be installed in showers and bathtubs, however it is important to check the height of the water outlets on the wall to determine the maximum shower height.

What is included in the purchase of Hoterway shower columns?

Hoterway ONE comes with a wall-fixing kit, flexible hoses connecting to the water outlets on the wall, the shower holder and the mixer plates.

The HOTBOX is supplied with a wall-fixing kit, flexible hoses connecting to the wall water outlets, a ceiling water spreader, a handheld showerhead holder, a shower derivative and two mixer plates.

The product installation has to be done by professionals?

The product is designed to be installed by a person without training in the area and takes a maximum of one hour to be installed. The installation operation is done according to the following steps:

  1. Turn off the general water supply and remove the existing shower system
  2. Make the markings to drill into the wall where you will attach the fixing kit to the wall
  3. Open the two holes in the wall and secure the two screws and the support plate supplied with the shower column
  4. Install the shower column on the wall-mounted kit
  5. Connect flexible hoses to wall water outlets
  6. Install the shower system
  7. Reconnect the general water supply

do Hoterway products need maintenance?

There is no need to perform any maintenance on the equipment or any product startup procedure. Simply install the product and it will be ready for use.

Can I keep the shower system I currently have?

You can keep your shower system current since neither ONE and HOTBOX shower columns require replacement of the mixer or shower system.

Is the water temperature in the Hoterway static or can it be regulated?

Hoterway heats the water before it reaches the mixer, i.e. you can continue to regulate the temperature of the water that will start hot immediately. If you choose the option with terstatic mixer, in addition to leaving hot water instantly, it will always come out at the temperature you set in the mixer.
