TIME FOR ENERGY EFFICIENT AND INNOVATIVE SOLUTIONS Expectations of consumers are changing. With the high volatility on energy prices and the increasing scarcity of fossil fuels, customers today are more than ever conscious of the cost of heating. The effects of climate change are now visible throughout the world and even the speed of this change seems to be accelerating. Because of this there is an increased expectation and demand for energy efficient products using renewable technologies that have low carbon emissions. With the drive towards Zero Carbon targets, with all the implications on Building Regulations, Code for Sustainable Homes as well as other policies and incentives, your customers will demand a heating solution that satisfies all these needs. A Brand you can trust Daikin Altherma is a well proven product with thousands of systems installed throughout Europe. Daikin has over 50 years experience in heat pump manufacture and is a brand synonymous with quality and reliability. The whole system is manufactured entirely in-house at Daikin's state of the art factories - this includes the all important highly efficient inverter driven compressor unit. A solution is in hand The Daikin Altherma air source heat pump is a highly flexible, energy efficient system that transforms available renewable energy from the solar heated outside air into usable heat for home heating and hot water. Because of its advanced technology, over two thirds of the heat generated by Daikin Altherma is free of charge! Daikin Altherma operates on low carbon technology; the pump does use electricity but even without the use of green electricity the carbon emissions are still much lower than a fossil fuel based boiler. Average Annual CO 2 Emissions Daikin Altherma 2660 kg/year Gas Boiler 4344 kg/year Fuel Boiler 6045 kg/year 0 1000 2000 3000 4000 5000 6000 kg/years Calculations based on data provided by Eurelectric (Union of the electricity industry), Eurelec Program - 2001 for EU27. 66 to 80% Free Energy, Lower Running Costs DID YOU KNOW THAT... The Daikin Altherma heat pump is a durable energy system that transforms and utilizes the inexhaustible, energy from the solar heated outside air into usable heat. Daikin Altherma can reduce heating costs by up to 50% compared to traditional boiler systems. A heat pump boiler works more efficiently and saves more energy than a traditional heating system using fossil fuel. Daikin Altherma generates 3 to 5 kw of free heat per 1kW of electricity used. 68% Daikin Altherma air/water heat pump boiler 82% Gas Boiler 100% Fuel oil Boiler Operating costs - Conditions: Required annual heating energy: 20,000 kwh.

DAIKIN ALTHERMA THE 3 IN 1 GUARANTEE FOR ABSOLUTE COMFORT Daikin Altherma is a unique system that heats, produces domestic hot water and can even cool spaces. Daikin Altherma offers your customer maximum comfort the whole year round. How does it work? Heat pumps work on a well established principle known as vapour compression or refrigerant cycle. They work in much the same way as the common refrigerator, a technology already used in every household, but in reverse. The air to water heat pump from Daikin extracts renewable heat from the outside air. The system consists of a closed circuit containing a refrigerant. A thermodynamic cycle is created through evaporation, condensation, compression and expansion. A heat pump 'pumps' heat from a low to a high temperature level. The heat is then transferred via a heat exchanger to the hot water heating system (under floor heating, radiators or fan convectors), and to the hot water cylinder in the home. For every 1kW of electrical input Daikin Altherma will deliver between 3 to 5 kw of usable heat. Two basic concepts of heat pump technology COP (Coefficient of Performance) or gain factor This number indicates the amount of usable heat the heat pump delivers for every kwh electricity the heat pump uses. This number is dependent on the interior and exterior temperature and is therefore only a snapshot indicator. SPF (Seasonal Performance Factor) or performance factor of the heat pump system The SPF takes into consideration the energy consumption of the heat pump system in conjunction with the average running hours in a typical heating season. DID YOU KNOW THAT... Daikin Altherma is technically superior to most other heat pumps because it has inverter technology and weather compensation built in as standard. Daikin Altherma is not just another heat pump. Super performance thanks to inverter principle The coefficient of performance (COP) of the Daikin Altherma heat pump is largely attributable to the Daikin inverter principle. An integrated frequencyconvertor adjusts the rotational speed of the compressor to suit the heating demand. Therefore the system seldom operates at full capacity and your customers only pay for energy they actually need. Slow start-up Temperature remains stable Heat pump with inverter Heat pump without inverter

A GOOD DAIKIN ALTHERMA DESIGN IN 3 STEPS STEP 1 Calculation of heat losses (Transmission and ventilation losses) STEP 2 Selection of Altherma system based on heat loss calculation and desired system water flow temperature (for low temperature application preferably a temperature regime of 40 C - 35 C) TIP: Use the available Daikin selection and software tools STEP 3 Selection of emission systems, after choosing Daikin Altherma unit, with a st = 5 C for Low temperature, and st = 10 C for High temperature above 55 C TIP: Remember to consider the pump characteristics! Heating Demand Versus Heating Supply The need for heating will be the greatest on the coldest day of the year. The maximum heating demand is, in the UK, only required for a few hours per year. Selecting a heat pump that covers the entire heating demand is not the most economical solution. In that case, the heat pump would be sized too large and the investment costs would be high. A mono-energetic solution results in a better balance between investment cost and consumption cost. In such a case, the heat pump provides the largest portion of the heating demands but, in extremely cold weather, it is supported by an electric back-up heater. The back-up heater is only utilised at temperatures below the equilibrium point. Heating consumption (kwh) Heating demand 2200 1760 1320 880 440 10% Coldest day of the year 90% of annual heating demand Equilibrium point Covered by heat pump Available capacity from heat pump Covered by back-up heating Heat pump Back-up heating Hours 0-8,0-3,2 1,6 6,4 11,2 16,0 Outside temperature ( C)
