Daikin Altherma

A heatpump is an electrical device which absorbs energy from the one fluid (e.g. water , air) and uses that energy to heat another fluid such as (e.g. water or air). A typical example is where a heatpump is used to heat the water circulating in an underfloor heating circuit.

The Daikin Altherma Low Temperature heatpump range is a leader in its field, having been the first heatpump to be awarded the european ECO Label for its compliance with strict ecological and performance criteria. It was also the first heatpump to be awarded the Quiet Mark for its low sound levels.

Highly energy efficient

Low temperature heatpumps are suited to operate with low temperature distribution systems like underfloor heating, low temperature radiators and fan coil units. The lower the output water temperature the more efficient their operation. The Daikin Altherma Low temperature heat pump range can achieve COP’s of up to 4.66 at A7W35. Water temperatures of 55°c can be achieved in space heating and 60 °c in domestic water while operation is possible down to an external temperature of -25°c on select units.

A Heat pumps high efficiency is made possible by the vapour compression cycle which uses a small amount of electrical energy to transfer between 2 and 4 times more thermal energy from the external air into the heating system water. Based on current oil and electricity prices, a heatpump can realise annual fuel bill savings of up to 70% when compared to oil or LPG boilers.

Different sizes and configurations

The Daikin Altherma Low Temperature heat pump range covers an array of capacities configurations and accessories to provide solutions to varying house types and sizes. Heating capacities range from 6 Kw to 16 Kw.

Daikin Altherma heat pumps have the following configuration options:

  • Monoblock system
  • Slit system

Monoblock system

The monoblock system combines all components in one outdoor unit so the installer runs the flow and return water pipes to and from the outdoor unit. There are 6 models available in 2 size ranges: 6-8KW and 11-16KW. monoblock-altherma

Split system

The Split system consists of an outdoor unit and an indoor unit. The outdoor unit is smaller in size than the monoblock. Refrigerant rather than water is then piped to the indoor unit which is available as either a wall mounted unit or floor mounted unit. As with the monoblock there are 6 models available in 2 size ranges: 4-8KW and 11-16KW altherma split

Advantages of heat pumps

Points to note when comparing Heat pumps to Oil / LPG Boilers

  1. Heat pumps operate at up to 70% cheaper that Oil / LPG boilers
  2. Heatpumps do not require oil tank, fuel re-order, fuel theft safeguards.
  3. No Carbon Monoxide emissions from heat pumps.
  4. No flue required therefore flexibility in position of indoor unit.
  5. Graduated bills via electrical provider as opposed to large one off oil bills.
  6. Additional hardware and control features available as standard.
  7. Reduced carbon emissions.
  8. Provides an outlet for indigenous wind and wave energy in the domestic market thereby reducing fuel import dependency
  9. Where underfloor heating is installed, a heatpump can provide the renewable energy requirement to meet the requirements of Part L of the building regulations.

In most cases a heat pump installation will cost no more than a boiler / solar combination to install and the heat pump will operate at significantly lower running costs so in simple terms it makes economic since to install heat pumps in new build houses and in many cases, subject to survey, in existing houses also.

Client Testimonial

We are happy with the heating system overall. The system has operated economically and reliably since installed. We have a very comfortable environment in the house all year around as well as plenty of hot water. We are delighted with the low running cost especially given we have the house warm all the time and hot water on 24/7 as we have a young family. The system operated for under 1000 euro over 12 months, verified by the energy meters fitted by our installer. We would recommend the system to anyone and are delighted to have chosen a Daikin air to water heatpump for our heating needs.
