What is Daikin Altherma? 1. Daikin Altherma is an Electrically Driven Total Comfort air-to-water heat pump system that utilizes an outdoor R-410A heat pump system 2. The system transfers this heat through refrigerant piping to a refrigerant-to-water brazed plate heat exchanger in the hydrobox (indoor unit on split system and incorporated in the outdoor unit on the MonoBloc System). Daikin Altherma was the first system of its kind in Europe to be recognized as a Renewable Energy Technology Did you know that...

Daikin Altherma - Conclusions The Daikin Altherma portfolio offers many attributes that make it appealing to the green movement with LEED, Low Energy and even Net Zero Energy applications. Scope Environment Efficiency Feature / Attribute 1. All Equipment contains materials that are fully recyclable. 2. Altherma system inherent design and operational features mean effective tie in to Grid-Tied Solar PV (Low start up amps, operating amps, no locked rotor amps etc). 3. DHW Production via Optional/3 rd Party Solar Thermal solution and using the Aero Thermal Daikin Altherma serving as the Auxiliary Solution. 4. A Heating and DHW solution with NO Localized CO2 emissions. 1. Efficient Heating and Domestic Hot Water with Optimized for Heating Air to Water Heat Pump system. 2. Enhanced energy savings via Inverter Compressor operation where energy consumption matches the load. 3. Further savings via the Outdoor Reset Function to control LWT depending on Ambient temperatures. 4. Operational efficiencies (COP up to 4.5) similar to or better than Geo-Thermal WSHP solutions, without the added cost of well drilling, excavation etc 1. Excellent flexibility for the architect / designer to apply the Altherma system to suit any home design, scale or performance scope. Application 2. Unobtrusive and aesthetically pleasing complete Heating, Cooling and DHW 3. Full utilization of hydronic circuit, thus small diameter piping, high heat transfer coefficient and comfort of Low Sound Level In-Floor Radiant, Low Velocity Fan Convectors or Radiators.
