Renovating a heating system and wanting to reduce energy costs? Interested in a heating solution with lower energy costs? Heat pumps are currently the most efficient indoor comfort system on the market: a cutting-edge technology with clear benefits for you and the environment. Depending on the model and the conditions, a Daikin Altherma air-to-water heat pump delivers between 3 and 5 kWh of usable heat for every 1 kWh of electricity it uses. That's a great ratio from 3:1 - 5:1!
Daikin Heat Pump experience
Daikin has more than 50 years of experience with heat pumps, and supplies more than one million of them to homes, shops and offices each year. This success is not just a quirk of fate: Daikin has always been at the cutting edge of technology and its goal is to provide you with turn-key comfort. Only a market leader can guarantee you this level of service and quality control!
High efficiency means low energy cost
Heating system efficiency is measured using the Coefficient of Performance (COP), which is the ratio of heat produced to energy consumed.
- Customers today are, more than ever, conscious of the cost of heating.
- There is not only the increasing cost of fuel oil and natural gas, but also the limited supply of fossil fuels and the problem of CO2 emissions.
- Energy efficient heating solutions are gaining in popularity.
- Daikin Altherma debuted in Europe in 2006 and since then has demonstrated significant economical advantages over traditional systems as highlighted on the following.
The Daikin Altherma technology delivers excellent efficiency due to the heat pump characteristics (using renewable energy from the outside air) and the part load benefits of the inverter compressor technology, using only the electrical energy needed to satisfy the requirements of the home.
Currently there is no appropriate U.S. recognized testing and rating standard for technology that is of Air to Water design and can solve Hydronic Heating, Domestic Hot Water and Cooling requirements in a single packaged solution. As such, the U.S. Department of Energy (DOE) has issued Daikin with Waivers (Case number: CAC-024, as published from page no. 34,731 in the DOE Federal Register on June 18th, 2010, and Case number CAC-028 as published from page no. 11,438 in the DOE Federal Register on March 2nd, 2011) and assigned an "Alternate Test Procedure" detailing testing requirements to establish full load COP and EER values.
In accordance with the terms of the DOE waiver, the Full Load Energy Efficiency Performance of the Daikin Altherma systems are as follows:
