The Daikin Altherma system can be combined with:

  • Under floor heating, one of the most comfortable heating methods
  • Fan coil units
  • Low temperature radiators to provide the comfort required

In addition, it can be connected to:

  • A domestic hot water tank to supply your hot water needs
  • Solar collectors, with optional solar kit, to complement the production of hot water
  • A room thermostat, to regulate the ideal temperature easily, quickly and conveniently

Benefits

Less energy, pleasant warmth in the home

Daikin Altherma heats up to 5 times more efficiently than a traditional heating system based on fossil fuels or electricity. By making use of the heat in the outside air, you use much less energy while still enjoying a stable and pleasant level of comfort. Daikin Altherma provides energy efficient, eco-friendlier heating.

Minimal installation cost

Daikin Altherma takes heat from the air. No digging or excavation works are required. Both the outdoor and indoor units are compact. The external unit can be located easily outside any building, including apartments. Without flames or fumes, there is no need for a chimney or constant ventilation in the room where the Daikin Altherma’s indoor unit is installed.

Flexible configurations

Daikin Altherma can be configured for use in both new and refurbishment applications, and connects to standard low temperature radiators, underfloor heating or fan coil units. If you already have a heating system, there is no need to change it all.

Entire comfort for your family

Daikin Altherma satisfies your heating requirements but it can also supply your sanitary hot water. It comes with a cooling option for hot summer days.

Environmental Comfort

Daikin Altherma works without oil, gas or other hazardous substances – reducing potential risk that goes together. Moreover, you don’t need a gas connection or a fuel tank. No risk of intoxication, smell or pollution from leaking tanks.

Split Type

The system consists of four components which together provide the ideal comfort and water temperature.

Altherma Split Diag 2

1A / Outdoor Unit: an efficient use of energy from the air
 Daikin Altherma uses a natural source of energy. The outdoor unit extracts heat from the outside air and transfers it inside through refrigerant piping to supply heating. The compact outdoor unit is easily installed and, as no drilling or excavation work is required, it can also be installed in condos and apartments.

1B / Hydrobox: the Heart of the Daikin Altherma System
 The hydrobox heats the water that circulates through low temperature radiators, floor heating systems or fan coil units and also provides domestic hot water. If you opt for the combination of heating and cooling, then the hydrobox can also reverse the cycle to provide lower water temperatures and thus cooling to the home.

2 / Domestic Hot Water: Tank for low energy consumption
 As for your domestic hot water, Daikin Altherma is just as clever. The unique lay-out and special placement of the system components maximize energy efficiency. The water inside the storage tank is primarily warmed up by thermal energy from the outside air, thanks to a heat exchanger connected to the heat pump. However, an additional electrical heating element in the domestic water tank can take care of extra heat required in the shower, tub or sink. At necessary intervals the water is automatically heated to 158°F or more to prevent the risk of bacteria growth. With Daikin Altherma, delightfully warm and perfectly safe water can be enjoyed at all times. Depending on the daily consumption of hot water, Daikin Altherma domestic hot water tanks are available in two different sizes.

4 / Solar kit
: The solar kit provides the transfer of solar heat to the Daikin Altherma hot water tank via an external heat exchanger. In contrast to tanks with two heat exchangers, this system allows the entire content of the tank to be efficiently heated with solar heat and, if necessary, with heat pump energy.

The Room Thermostat:

Altherma Thermostat

The large LCD screen on the room thermostat indicates all the necessary information regarding the setting of the Daikin Altherma system in a blink of an eye. The user can also easily navigate between the different menus whose most common functions and modes include:

  • Setting the temperature of the room based on measurements from the built-in sensor
  • Cooling and heating mode
  • Off function (with integrated frost protection function)
  • Vacation function mode
  • Comfort and reduced function modes
  • Time (day and month)
  • Programmable weekly timer with 2 standard and 5 pre-set programs
  • Keylock function

The outdoor unit:

  • Compact, weather-resistant and easy to install
  • Contains an inverter controlled compressor for energy efficiency and precise temperature regulation
  • Heat pump operation range: heating and domestic hot water to -4°F outside temperature

The Hydrobox:

  • Available in two versions: EKHBH for heating only, EKHBX for heating and cooling
  • Built-in electric back-up heater for additional heating during extremely cold outdoor temperatures or as back-up in case of problems with the outdoor unit
  • 2 shut-off valves to assemble the water outlet and inlet
  • Compact and easy to install: all components are pre-assembled, all parts are easy to reach for maintenance. Wall-mounting is comparable to a traditional gas heater.

Heating and Cooling:

If you choose Daikin Altherma with an indoor unit EKHBX, it can not only heat the house, but also cool it. The heat pump is then equipped with a reversible 4-way valve, whereby the refrigeration cycle is reversed and heat is removed from the rooms. The indoor unit can cool rooms via under floor cooling or fan coil units.

Set temperature limits:

To prevent incorrect manual adjustments, temperature limits can be implemented for both cooling and heating. With under floor heating, for example, it is important that the temperature of the water is controlled to the type of floor element. To prevent condensation problems, the temperature for floor cooling can never be lower than 64.4°F. For fan coil units, the water temperature can be allowed to decrease to 41°F.

Monobloc Type

The system consists of four components which together provide the ideal comfort and water temperature.

1A / Outdoor Unit: an efficient use of energy from the air Daikin Altherma uses a natural source of energy. The outdoor unit extracts heat from the outside air and transfers it inside through refrigerant piping to supply heating. The compact outdoor unit is easily installed and, as no drilling or excavation work is required, it can also be installed in condos and apartments. The monobloc outdoor unit version combines both the condensing unit and the hydrobox, simplifying installation while retaining all the benefits of the original design. Since the entire refrigeration circuit is contained in the outdoor unit, no refrigerant piping needs to be installed and special handling of refrigerant circuits is no longer required. As a result, Daikin Altherma Monobloc Type can be installed by any Daikin trained heating specialist. Installation time is also reduced, resulting in lower installation costs across the board.

Altherma Monoblock Outdoor

The Daikin Altherma monobloc is available in different versions

  • heating only or heating and cooling
  • with bottom plate heater
  • single phase
  • 36MBH, 48MBH, or 54MBH
  • High efficiency compressor
  • Expansion tank
  • Tank with back up heating
  • Pressure gauge (water circuit)

Freeze protection of hydronic parts

In order to protect the water pipes from freezing up during winter, insulation is provided for all hydronic components and special software has been applied to activate the pump and back-up heater if necessary. This prevents the water temperature from dropping below freezing point and can minimize the need for the addition of glycol to the water pipes.

Built-in electric back-up heater

For additional heating during extremely cold outdoor temperatures. The Daikin Altherma Monobloc is standard equipped with a 6 kW back-up heater, which can be adjusted to 3 kW. If necessary, an “in line” back-up heater of 6 kW can be mounted indoors (also adjustable to 3 kW or 3.5 kW).
