HOW DO YOU GET HEATING AND HOT WATER FROM AIR? Introducing the Panasonic AQUAREA Air Source Heat Pump Aquarea High Performance An AQUAREA air source heat pump captures heat from the air and transfers this heat into the home via a compressor and condenser. By applying a little more energy from electricity a heat pump can raise the temperature of this heat energy to the level required in the home. Heat Pumps offer an energy efficient way of providing heating in the home, as they acquire 78% of their heat energy from free and renewable sources. From 3 to 16kW For a house with low temperature radiators or under-floor heating, our high performance Aquarea HP is an ideal solution, which can work as a standalone unit or be combined with an existing gas or oil-fired heating system. This new solution is ideal for low energy consumption homes.

The heat pump must be placed a minimum of 300mm from a wall , on a plinth so as snow drifting cannot occur in front of the machine. You must also leave clearance in front of the machine, do not locate it in front of a wall or fence. It is advisable to locate the machine so as it is not facing directly in towards a door or window as the air coming from the fan is very cold when machine is in full operation. -15ºC Aquarea T-CAP and High Performance have extremely high efficiency even at -150C Where can I locate the heat pump control panel? The controller comes with a 15m lead which is coiled up in the heat pump. It can be left in the heat pump or it can be sited in your dwelling within the 15m or further if required using an extension cable. Coefficient of Performance / COP The Coefficient of Performance (or COP) is the efficiency ratio of the amount of heating provided by a heat pump compared to the energy consumed by the system. The higher the Coefficient of Performance the more efficient the system. AQUAREA What are the hot water cylinder requirements with a heat pump? Any type of cylinder can be used; copper, stainless steel or glass lined. The key component is the 3m2 or Hi Gain coil which must be in any cylinder that you used with any heat pump. It would be desirable to have an electrical immersion fitted also. UP TO 78% ENERGY SAVINGS * RENEWABLE ENERGY The efficiency of the Heat Pump is tested at 70C outside temperature and 350C water temperature. The COP is normally between 4.5 and 5. A COP of 4.74 means that the heat pump gives out 4.74kW of heat energy for every 1 kW of electrical energy used. 0,78 kW RENEWABLE ENERGY 78% OUTDOOR FREEENERGY AIR SOURCE ENERGY 1kW HEAT 22% 0,22kW ELECTRICITY COP = Heat Output kW Heat Input kW ELECTRICITY AQUAREA GAS BOILER Power Input/Energy Consumption Power Output Heating Capacity OIL BOILER 1kW 0,9kW GAS HEAT 1kW OIL ELECTRICITY ELECTRICAL HEATING 0,9kW HEAT 1kW ELECTRICITY Conditions: Water inputCONSUMPTION temperature 300C.Water Output Temperature 350C POWER INPUT / ENERGY POWER OUTPUT / HEATING CAPACITY (kW) How much space is needed in the boiler house? Heat pumps normally require a footprint of 1m x 1m and are approx 2m high. All heat pumps also require a buffer tank of approx 15 litres per kW so a typical 10kW heat pump requires a minimum of a 50/75 litre buffer. The buffer tank needs a similar footprint as the heat pump. ELECTRICITY HEAT OTHER HEATING SYSTEMS 4 | Heat Merchants How do I size or know what heat pump i need? There are a number of pieces of information required to size a heat pump, a set of floor plans of the house, type of construction, location of site, hot water requirement etc. Once we have those we can calculate size using the Aquarea Software Package and produce a design, select a heat pump & give estimated running costs and give estimated comparisons of carbon emissions and costs verses oil, gas etc. 1kW HEAT How do I get my heat pump commissioned & how much does it cost? When your installer & electrician have completed their installation in full, complete the Panasonic Pre-Commissioning Check List and send it into the branch in which you bought your heat pump. They will book it in with the Commissioning Engineer to have it commissioned and validate your warranty. The cost of commissioning is €250 plus VAT. (Subject to change please confirm with your branch). What type of heating system works best with heat pumps? The best system to use is one that works at low temperatures between 350C - 450C. Underfloor heating is particularly suitable for use with the lower temperature water from heat pumps. The ideal solution if not using under floor heating is to use aluminium radiators which operate efficiently with a flow temperature of 450C. Standard panel radiators can also be used if they are designed correctly. Free training and consultation for installers is available across our product range. Call 090 6442300 to speak with our renewable energy team or arrange a convenient time. Renewable Energy | 5 Sample Hydraulic Installation for monobloc systems PAnasonic Aquarea Heat Pump Manager The Panasonic Aquarea Heat Pump range uses a 2-pipe Y-Plan plumbing arrangement. What this means is that the heat pump controls a motorised 3-port diverting valve and carries out space heating or domestic hot water production. This allows for a low temperature heating system i.e. under floor heating or low temperature aluminium radiators, but still allows for high attainable domestic hot water temperatures. The control of the heat pump can be done through the flow temperature or as with a conventional system, a single room thermostat or multiple thermostats. The Heat Pump Manager (HPM) is specially designed to ensure the Aquarea heat pump systems deliver maximum performance and comfort allowing accurate temperature control based on the outdoor temperature. This simple plumbing arrangement below illustrates a typical domestic application, in this case under floor heating on one floor (zone), low temperature radiators on a second floor (zone) and domestic hot water. N Close Open l n Cool Heat n n Close Open Schematic Diagram - The relevant standards and directives must be observed. Close Open Sample Hydraulic Installation with Water & Heating The HPM is the ideal solution if it is necessary to combine multiple heat pumps and or use a secondary heat source such as solar, gas or oil fired boilers with the heat pump which makes heat pumps suitable for larger properties when a large 3 phase unit is not suitable or retro-fit projects where the existing heating system is maintained. The HPM control will interface between the different heat sources and utilises the most appropriate depending on the user preferences. The HPM also allows for remote access and monitoring over the web using Panasonic’s unique internet applications. Panasonic have created hundreds of HPM schematics which are available on the Panasonic ProClub website and the Heat Merchants Technical Support & Design Team can assist in the choosing the best option for your project requirements.
