Daikin Underfloor Heating

Daikin Altherma is a highly flexible, energy efficient home heating system that extracts heat from the outside air, raises this heat to a higher temperature and then distributes warmth around the home through high quality heating units. At the heart of the system lies an air-to-water heat pump. Altherma is available in heating only or reverse cycle (heating and cooling) options.

How does Underfloor Heating work?

The heating system is located in your floor and heats up your home from the floor up, so you’ll feel the warmth on your feet. This heat then radiates upwards surrounding your entire body in warmth. You’ll enjoy a cozy temperature in just 3 steps:

  1. Heat pump extracts free low temperature heat from the ambient air

  2. The system raises the temperature of the recovered heat

  3. This warmth is then distributed throughout your home via heat emitters


How does Altherma work?

Altherma uses a refrigeration cycle to transfer heat from the ambient air into your home. This is an efficient process for transferring heat energy as it only requires 1 kilowatt of electricity to pump 3 to 5 kilowatts of heat into your home. In other words, 66-80% of the heat energy produced by Altherma comes from the outside air and is free of charge.

To make this happen, there’s an indoor unit (hydrobox) and an outdoor unit, both of which can be professionally installed by Glow. Circulating between the indoor unit and the outdoor unit is a refrigerant that absorbs heat energy from the ambient air and releases that heat energy into the indoor unit or hydrobox. A
secondary heat exchange occurs within the hydrobox as the heat absorbed is transferred to the underfloor reticulation circuit to distribute warmth into your home.

Additionally, if the hydrobox is connected to our domestic hot water tank as well, it is then possible for Altherma to provide for your homes year round hot water needs as well.

4 Reasons to choose Daikin Altherma

  1. Daikin’s Altherma system utilises free heat from the ambient air to maintain ideal comfort conditions in your home. In addition, the inverter technology inherent in Altherma means your energy savings are even greater.

  2. Even in the coldest weather, the Altherma system is still able to extract heat energy from the ambient air. In the event there is insufficient heat in the outdoor air, Altherma is equipped with a back up heater to cover the shortfall.

  3. Daikin’s Altherma solution provides for easy and flexible installation. This system is ideal for new homes as the underfloor piping can be installed during the construction phase and for existing homes, the piping can be connected to radiators installed around the house.

  4. Altherma works without the need for oil, flammable gas (LPG, Natural) or other hazardous substances thus reducing the potential risks that these fuels can create. Furthermore, there is no need for a gas connection or a fuel tank.

Which heating system to use?

There are several different options available to provide heating in your home and Altherma is compatible with all of them. The selected system can simply be connected to the Altherma unit. Below are examples of some of the most commonly used heating emitters:

Underfloor heating is possibly the best solution for new installations. The main benefits are:

  • Maximum comfort due to radiated heat

  • Maximum efficiency compared to other heat emitters

  • Unobtrusive [i.e. no wall space required]

  • Water flow temperatures typically 35 to 40C

A fan coil system is more flexible in that it can provide both heating and cooling if required. The main benefits are:

  • Able to heat and cool

  • Cased or concealed units

  • Individual control

  • Ease of installation

  • Water flow temperatures typically 35˙C heating 7˙C for cooling option

Radiators are a traditionally used system that costs relatively inexpensive compared to other systems. The main benefits are:

  • Traditional heating solution

  • Low capital cost

  • Ease of installation

  • Water temperature typically 50˙C with heat pumps (radiators must be sized accordingly)
