What is the basic principle of technology?

Hoterway technology combines the characteristics of a phase changing material that changes
the state at about 45 ° C (solid <-> liquid) with an heat exchanger with unique characteristics
that stores heat at constant temperature when the inlet temperature is higher than 45ºC
releasing then this heat with a substantially higher heat output when cold water is passing
through the device.

How does this technology heat the water?

Hoterway is installed in the hot water distribution circuit in order to heat the water in the
pipes until the hot water arrives from the heater. During this period the cold water flows
through the exchanger and the material that was in the liquid state (> 45ºC) will be forced to
the phase change (solid state) while releasing the heat accumulated in the last use. Because it
is a phase change process, the release of heat occurs at a constant temperature.

Where does the accumulated heat come from?

When the hot water reaches the consumption point the phase change process is reversed. As
the hot water is at a temperature higher than the phase change temperature of the material it
will change from the solid state to the liquid state, also at constant temperature. At this
moment the water enters is supplied to the Hoterway at 50 ° C, as an example, and then
Hoterway will release the water flow at 46 ° C ; this temperature differential is imperceptible
to the user but it is enough to charge the heat for the next use.

Is the hoterway connected to electricity?

No, the hoterway is a thermal battery that is not connected to any power source, uses only the
heat from the hot water stream to instantly heat the water from the pipe at the beginning of
the next use.

What’s the lifecycle of the battery?

The heat storage / release is based on a stable and reversible physical phenomenon. Hoterway
thermal batteries have a thermal degradation of less than 10% over a period of 50 years which
means that during this time the heating capacity of hoterway thermal batteries will have a
maximum of 10% reduction.

Hoterway ONE details

Is it compatible with any shower?
Yes, with the exception of recessed shower systems. To install the hoterway ONE shower the
user only has to access the cold water and hot water connections in the wall to connect the
flexible hoses of the ONE column.

Can it be installed in showers and bathtubs?

Yes, it is important however to check the height of the water outlets in the wall to determine
what the maximum height of the shower will be.

What comes with the product?
Hoterway ONE is supplied in an installation kit consisting of the column with flexible
connections, a thermostatic mixer, shower and hose and installation accessories.

Does the installation have to be done by a professional?
No, the product is designed to be installed by an untrained user. The installation operation
boils down to the following:

1) turn off the water and remove the current shower system

2) make the marking of the drilling

3) open two holes and fix support plate with screws provided

4) install the column

5) connect the flexible hoses

6) install the shower set

7) turn on the water

Is it necessary to maintain?

No, it requires no maintenance or any start up procedure. Just install and start using.
