What is the function of the Hydrobox in a heat pump system?
The Hydrobox is a core component of a heat pump that transmits the extracted thermal energy to the heating system in the building.
The state-of-the-art ESTIA Hydrobox as an indoor unit from the TOSHIBA heat pump series is one of the key components of the heating system. Let's take a closer look at this technological marvel.
Get pumped –
without having to go to the gym! An ESTIA air-to-water heat pump is also used to ensure efficient energy management.
Heat generation is provided completely out of thin air, as the heat pump uses the energy from the surrounding air to ensure cozy heat in your home even when it's icy outside. In simplified terms, the system consists of two main components which are connected in a refrigerant circuit: the outdoor unit and indoor unit. The former is mounted on the outside of the building and ensures that the thermal energy is drawn out of the air and routed into the building in the form of highly heated coolant.
The indoor unit processes the energy in a heat exchanger and emits the heat to the heating systems and the building's hot water tank. The Hydrobox is an example of this type of indoor unit.
Space-saver offering a whole host of possibilities
The heat, which is introduced to the Hydrobox from the outdoor unit in the form of the pressurized, gaseous refrigerant, is transferred to the water system via a plate heat exchanger. This transformation makes the Hydrobox one of the key elements of a heat pump.
Now the heating system and domestic hot water tank can be supplied with the heat they need to envelop your home in a cozy heat or provide the water you need for a long, soothing bath.
Due to the various individual demand profiles, the ESTIA Hydrobox is available in multiple variants from 4–16 kW. In the case of the 8 kW variant, supply water temperatures of up to +65 degree Celsius are achieved with an energy efficiency class of A+++, for example.
Unboxing the box
Even though the Hydrobox is extremely compact with dimensions of 72.5x45x23.5 cm, it packs in a whole load of technology. Weighing just 27 kg, the current Hydrobox from the TOSHIBA ESTIA series is also 55% lighter than its predecessor from series 5, making transport and installation significantly easier.
The white powder coating ensures it is understated, elegant, and durable – and the technical details under the hood speak for themselves.
The Hydrobox operates in energy efficiency class A++ to A+++.
It is also extremely cost-effective and frugal with its consumption of power. The operating range of -25 to +43 degree Celsius allows a high degree of flexibility at the installation location. Depending on the model series, a supply water temperature of up to +65 degree Celsius is achieved when heating, something which significantly expands the possible uses for different heating systems.
Integrated backup heater
The integrated backup heater is available in variants with 3, 6, or 9 kW, depending on what is required. Of course, the expansion vessel and the compact e-box with new layout and PCB design are included as standard. The TOSHIBA ESTIA control unit on the front of the Hydrobox impresses with its new features and ease of handling. The icons are clearly placed and ensure optimum operating comfort for the entire system: Functions such as water temperature, nighttime operation, timer programs, or the silent quiet function can be called up at the press of a button.
Room remote control
It's best to use a separately available room remote control (which mirrors the integrated control unit) or make use of the TOSHIBA Home AC Control app conveniently from your smartphone to operate the system from the comfort of the couch.
Last but not least, the Hydrobox is designed such that maintaining and servicing all main components is easy, as they are arranged intelligently and are therefore easily accessible.

What is the difference with the All-in-One unit?
When installing an ESTIA heat pump, the question as to whether a Hydrobox or an All-in-One unit is to be installed indoors is sure to come up sooner or later.
Which of the two systems is more suitable depends entirely on the individual circumstances and requirements.
A key criterion when making the decision is definitely the spatial conditions – while the Hydrobox can be placed almost anywhere due to its compact size, a 210 l stainless steel water tank is integrated directly into the system with the All-in-One unit. This is a benefit if there isn't any space for multiple units in the basement or if there isn't a basement at all, meaning the unit needs to be installed in the living area.
By the way, if you want more information on the ESTIA All-in-One series, we have put together a separate blog article which you can access HERE.
Anyone who wants more flexibility when it comes to the size of the water tank or would prefer two separate units due to the particular space requirements would be better advised to go for a Hydrobox and an external water tank.
No matter which of the two variants you opt for, both ESTIA systems combine state-of-the-art technology, maximum operating comfort, and tried-and-tested quality from TOSHIBA.
ESTIA air-to-water heat pump
The ESTIA air-to-water heat pump recovers energy from the air and transfers it to the heating system. This job is carried out by an environmentally friendly refrigerant and an efficient compressor. The heat generated during this process is transferred to the water pipe system via a heat exchanger. The domestic hot water and heating water are thus heated to the required temperature. This energy-saving system works efficiently down to frosty outdoor temperatures of -25°C.

Environmentally friendly and cost-effective
The ESTIA Hydrobox from TOSHIBA is another milestone on the path to the energy transition. It has achieved an energy efficiency rating of A++/A+++ and therefore leads the way towards an environmentally friendly future in which the use of renewable energy plays an ever greater role.
As one of the main components of the air-to-water heat pump, the Hydrobox is ahead of the competition when it comes to quick and easy conversion to an environmentally friendly heating system.
Only the energy required for the sustainable heating system is plucked out of thin air.
