Altherma Benefits

Less energy, pleasant warmth in the home

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. Also, maintenance requirements are minimal making your running cost low. Thanks to the inverter technology, your energy savings are even greater.
Minimal installation cost

Altherma takes heat form 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 flats. Without flames or fumes, there is no need for a chimney or constant ventilation in the room where the Altherma indoor unit is installed.
Flexible configurations

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

Complete comfort

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

Absolutely safe

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

Altherma System Components

Outdoor Unit - An efficient use of energy from the air.

Outdoor UnitAltherma uses a natural source of energy. The outdoor unit extracts heat from the outside air and raises its temperature to a level high enough to supply heating. This heat is then transferred to the indoor unit through cooling agent pipes (thus, the additional advantage is that the pipes can never freeze).

The compact outdoor unit is easily installed and, as no drilling or excavation work is required, it can also be installed in flats and apartments.

Indoor unit : Hydro box - The heart of the Altherma system.

Altherma Hydro box indoor unitThe indoor unit 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 indoor unit can also decrease the water temperature to distribute a refreshing coolness.
 

Domestic hot water tank - for low energy consumption.

Hot Water CylinderAs for your domestic hot water, Altherma is just as clever. The unique lay-out and special placement of the system components maximise 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 70°C to prevent the risk of bacteria growth.

With Altherma you can enjoy delightfully warm and perfectly safe water at all times. Depending on the daily consumption of hot water, Altherma domestic hot water tanks are available in three different sizes, with the largest one being the most efficient.

System controls

Altherma ControlsSystem controls and the user interface are contained within the hydro-box and feature a weekly timer that enables the indoor temperature to be controlled according to user requirements. The timer is programmable on an hourly or daily basis so that temperatures can be reduced at night or during holidays and increased prior to rising in the morning or returning home. User comfort according to personal preference is thus maintained at all times. Where control over individual room temperatures and comfort levels is needed a conventional room controller should be added.
 

Solar as optional extra

The Altherma system can be perfectly combined with solar collectors to produce hot water. The sun provides 30 to 70% of the energy required for our hot water needs. Altherma, your total solution, thinks of the future.

* Should be considered alongside the general upgrade of the building fabric’s thermal conductivity (reduced U-values) BER/EPC also advised.

Altherma are A+++ heating and hot water solutions - one of the most efficient systems on the market today. Altherma systems are covered by the European Eco label which is only awarded to the top products in the market.

An air-to-water heat pump takes its heat from the outdoor air which means that it does not need any collector circuit but still ensures great savings.

This system transfers heat by direct vaporization when air passes through a heat exchanger. Even cold air contains sufficient heat to vaporize a refrigerant.

There is no need for bore holes and ground collectors so installation is quick and simple and can be installed in any type of house.

This also means that the air-to-water heat pump is a perfect and highly efficient solution for areas where it is not possible to drill for rock heat, or where the garden is too small to install a conventional heat pump collector system.

1.	Fan/Evaporator takes heat from the air to boil the refrigerant at low temperature.
2.	The refrigerant is then compressed in the compressor, causing the temperature to rise.
3.	The heat is given off to the hot water and heating system in the condenser.
4.	Heating and hot water pump.
5.	The expansion valve controls the pressure in the refrigerant circuit.
6.	Cold refrigerant re-enters the evaporator.

Free fuel from nature

The air-to-water heat pump produces far more energy than it consumes. For every kilowatt-hour purchased you receive a free contribution from nature comprising a further three to four thermal kilowatt hours, which are available as heating capacity.

How Air Source Heat Pumps Work

An air source heat pump system works using the process of refrigeration. The refrigeration system found in an air source heat pump is made up of a compressor along with two copper tubing coils, one situated inside the building and one outside; to help in the transfer of heat aluminum fins surround each coil. In the process of heating the outside coil extracts heat from the air (source) through a refrigerant contained in the coil which in the process evaporates the refrigerant liquid into a gas. Condensing the refrigerant back into a liquid the indoor coil releases heat from this very process. Turning air source heat into home heating and hot water is just that simple!

Heat Pump solutions for Ireland’s summer and winter!

With air source heat pumps the advantage to the home or business is enjoyed all year round. The truly clever part of using an air source heat pump system is that the whole heating process between air source and home or business can be reversed by use of a reversing valve which can change the direction of the refrigerant flow to either cool the building in the heat of summer or warm things up nicely in the colder months!

Daikin offers you two heat pump choices for low temperature applications:

1. The Daikin Altherma split heat pump system with an outdoor unit and indoor unit, or
   
2. The Daikin Altherma monobloc heat pump system which comprises of a comprehensive outdoor unit only.

Both Daikin heat pump systems can be combined with under floor heating systems, fan coil units, low temperature aluminium radiators to provide the customer with the comfort he or she requires. The Monobloc version has all hydraulic parts located within the outdoor unit. In this system the water pipes, rather than refrigerant lines, run indoors from the outdoor unit, making installation much quicker and easier for the domestic installer. This option is also the best option if the space for a plant room is limited.

When replacing an existing heating system with the Daikin Altherma High Temperature, radiators do not need to be replaced. Daikin Altherma High Temperature replaces your conventional boiler and perfectly supports existing high temperature radiators with water temperatures up to 80°C if required.

This system is similar to the split system by using an outdoor unit to extract heat from the outdoor air. This heat is transferred to the indoor unit via refrigerant piping to the indoor unit. The indoor unit further increases the temperature, allowing water temperatures up to 80°C for heating through radiators and for domestic hot water use.

Daikin’s unique cascade compressor approach to the heat pumps (one in the outdoor unit/one in the indoor  unit) means optimum comfort at even the coldest outdoor temperatures, without the need for an electric back up heater.
