Hoterway throughout the house.
Hoterway throughout the house.
Hot water in all taps, no waiting, no waste.
The Hoterway IN system is a global solution that enables the supply of instant hot water to all taps in the home.
It consists of a set of thermal batteries installed in the compartment served by hot water and a central module installed next to the hot water heating/storage point.
Comfort and efficiency.
Hoterway IN ensures hot water without waiting 24 hours a day, 365 days a year without wasting energy.
Hoterway IN thermal battery
The fully passive operation, is based on a thermodynamic phase change process.
The thermal battery is connected to the DHW (Domestic Hot Water) circuit and to the return circuit, thus providing instantaneous hot water to the consumption points, with no associated energy consumption.
Heat preservation between uses is ensured by high efficiency thermal insulation achieved with vacuum panels that ensure a heat loss of less than 20% in 24 hours.
In addition to the water connections, the system integrates a controller, two temperature sensors, and a local solenoid valve that will allow the return circuit to be activated temporarily and only in that compartment in situations where the consumption profile does not ensure the full recharge of the battery passively.
This ensures that every time the user opens a tap, the battery is charged and the water will always come out hot within the first few seconds. The controller is connected serially by cable (RS485 protocol) to the central Master system, located near the heating point/hot water storage.
Central Module IN Master
Control management and communication.
The central IN Master module manages the requests for support to the return circuit that are made by each of the compartments, managing the priority of responses and the activation of the circulation pump.
As an option, a communication module can be integrated with the exterior that will send to a database all the information from the system, allowing access to the status in each compartment, recorded temperatures, and history of requests for support to the circulation circuit.
The central module is connected to the compartment modules via a cable in a serial connection. The electrical panel supplied with the system is complemented with a set of basic components: Circuit breaker, Power supply, Relay and DHW circulator pump.
Elegance and simplicity
The Hoterway IN thermal battery should be installed as close as possible to the points of consumption in the room, and maintenance access should only be provided to the top of the thermal battery.
The access cover is composed of a wall mounting ring and a removable cover that provides maintenance access allowing to replace/check the electrovalve and temperature sensors with minimal aesthetic impact.

FAQ - Product
In a conventional installation without a return circuit, the user has to open the tap to bleed cold water from the pipe until hot water reaches that point of consumption, thus wasting several liters of drinking water every time he uses hot water.
On the other hand, in case this same installation has a return circuit (conventional solution), more than 50% of the energy consumed to heat water will be wasted due to heat losses and electrical consumption of the pump.
The Hoterway IN system is the only solution on the market that instantly heats stagnant water in the hot water pipe (which becomes cold when there is no consumption) avoiding water waste without increasing energy consumption.
The solutions available on the market are based on controlling the usage time of the return circuit with the aim of reducing energy waste. Some systems detect hot water consumption and activate the return circuit to deliver hot water to the point of consumption, other systems activate the pump based on user behavior.
However, none of the systems on the market offers a similar response to the continuous use of the return circuit, i.e. reduces energy consumption at the expense of reduced comfort, and for this reason this highly inefficient practice is still recurrently used.
Hoterway IN provides instantaneous hot water without using the recirculation pump, presenting the same response as a continuous use return circuit, but without the energy waste of this type of solution.
The Hoterway IN systems presuppose the installation of the thermal battery at the points served by hot water, remaining inside the wall or in a technical area of the room.
As it is maintenance free, the IN heater can remain inaccessible inside the wall with only the access cover in case the temperature sensors, the solenoid valve or the control unit need to be replaced.
In addition to the system components, it is also necessary to install the return pipe and the communication cable connected between the controllers and the Master.
The AuditWaiting tool presents a simplified analysis of the DHW distribution network by providing the response times of hot water in each room. You will thus know at the design stage how long you will have to wait for hot water in each room.
In addition to response times you will also know how much water you will waste if you don’t use the return circuit and how much energy is wasted if you do use the return circuit.
We will also present the proper Hoterway IN system with an indication of the consumption points where we recommend the installation of the Hoterway IN thermal battery and an analysis of the return of investment based on the proposed solution.
FAQ - Technology
Hoterway IN thermal batteries combine the thermodynamic characteristics of a specific material (Phase Change Material) with a heat exchanger with unique features and patented geometry.
The ability to accumulate heat at constant temperature allows the thermal battery to instantaneously heat the water, which is cold in the pipes when there is no consumption, and then replace this heat only by using hot water.
Hoterway IN thermal batteries are installed in each room supplied with domestic hot water in order to heat the stagnant water in the pipes until the hot water arrives.
During this phase the phase change material (initially in the liquid state) will change state releasing heat and instantly heating the water. As heat is stored at a constant temperature the hot water is supplied to the mixer at a temperature between 42 and 45ºC.
When the hot water arrives, the phase change process is reversed and the material starts to pass from the solid to the liquid state, taking advantage of the temperature at which the hot water is supplied, which is now higher than the phase change temperature of the material.
The heat accumulation is unnoticeable because it only happens in the range above 45ºC, that is, hot water is always supplied to the mixer above 45ºC.
In case the consumption time does not ensure the complete replacement of heat, the system communicates with the central unit to request support from the recirculation circuit for a brief moment.
