Heating All-in-one comfort for residential applications 2025 NEW
70 In order to achieve their goals, they are betting on heat pumps And at Daikin, we are convinced that they’re right. Heat pumps are more than ready to take on the challenge of home decarbonisation. They are not a technology of the future, but an established solution, ready to provide comfort. Heat pumps are ready to take on the challenge of home decarbonization and Daikin is ready to be the most suitable partner in this challenge. Your next heating system will be a heat pump Did you know? In several European countries, heat pumps are already installed in more than 50% of new buildings. In renovations, heat pumps are increasingly being considered as a replacement for boilers, especially for high-temperature models with a similar leaving water temperature of 70 °C. Home decarbonisation is the sustainability challenge of today. It’s the newest addition to the global paradigm shift towards a more sustainable economy. In the automotive industry, agriculture and even in air travel, efforts have already been made to reduce or eliminate carbon emissions from energy sources. Next on the list: homes. The European Union pledged to “play a central role” in achieving net-zero greenhouse gas emissions by 2050. Daikin Altherma is the absolute most sold hydronic heat pump brand in Europe, since 2006*. Our hydronic heat pumps are 100% manufactured in Europe. *source: BRG Building Solutions – June 2024 data/report A million homes. One heat pump.

72 4 Steps to decarbonising residential heat Strengthened new build rules Increase replacement rate 2020 2030 40% One of the biggest challenges we face to ensure a healthy and sustainable environment and contribute to carbon neutrality is to maximize usage of renewable energy, specifically when heating our homes. The majority of residential housing is still heated with outdated systems, often using polluting fossil fuels such as coal and oil. The challenge involved in tackling this is made all the more clear by The European Green Deal, which is a set of policy initiatives by the European Commission with the key aim of making Europe climate neutral in 2050 using green technology. All European member states have already put measures in place to ensure that new build houses and apartments have a better carbon performance by making an improved building envelope and the use of renewable energy mandatory. As a result, Daikin estimates that heat pumps already have up to 50% market share in new (single family) houses. A considerable additional benefit of hydronic heat pumps is the ability to use it to cool as well heat, which is increasingly becoming a consumer requirement. This is partly due to the climate change effect, but also because of the higher insulation level built houses. Today’s replacement rate is, on average, 1% of the total number of heating systems installed per year and meeting the minimum target would require that replacement ratio to double within the coming 10 years. Substituting heating devices with more efficient ones will constitute a move towards reducing CO2 emission. The challenge however is to motivate EU citizens to choose renewable heating more often, thereby convincing those in the replacement market that heat pumps are an efficient, cost-effective and established solution.
73 End fossil fuel incentives Renewable heating standard in replacement 100% 2050 Policy makers could avoid incentives for fossil fuels. Currently, direct or indirect incentives benefit oil or gasbased boilers, due to different taxation of heat pumps compared with boilers for instance. While doing this, the gap between today’s electricity and gas prices in many member states is too high to make a heat pump an economically attractive investment for EU citizens. In the short term, government incentives can help accelerate the transition to carbon-neutral heating and make heat pumps accessible to all Europeans, but in the longer term more balanced energy prices and a correct indication of the energy and carbon performance of a building need to support the end user motivations to invest in heat pump technology. At Daikin, we believe heat pump systems have to become the standard when replacing heating systems. It is a fact that heat pumps are increasingly capable of high efficiencies, even at lower outdoor temperatures. The hydronic heat pump technology has developed quickly in recent years, making it fit for any type of residential building in Europe whether it is for the new build market or the replacement market. By increasing the share of green electricity to 60% of total EU electricity production, heat pumps will continue to increase their contribution to a decarbonized residential heating world. The future At Daikin we’re excited and passionate about taking on the changing environment and playing a key role in bringing this innovative technology into people’s homes while ensuring all stakeholders, such as installers and architects, are on board. We can do our bit as well by making installation as simple as possible through great design. Europe has the technology, the expertise and the investments to expand the heat pump market further. From single family to multi-family homes, from small to large commercial buildings and industrial plants, heat pumps today are ready to go mainstream. All the signs are indicating that we need to act now! Let’s convince those in the replacement market that heat pumps are the future and increase awareness regarding energy, cost-efficiency and environment-related advantages. Heat pumps start to play a crucial role in decarbonizing Europe, and in certain areas there has already been an impressive uptake. For example, heat pumps are the default heating system in Sweden and enjoy 50% of the market share in new builds in some European countries. However, in the whole of Europe, renewable heating via heat pumps represents only 10% of all heating systems installed annually. This contrasts sharply with the EU Commission’s ambitious target by 2030: 40% penetration of renewables in heating and cooling. At Daikin, we see the solution will be to take 4 steps to decarbonizing residential heat, in order to achieve the EU Commission’s targets by 2030.

80 reasons to choose a heat pump 6 1 A heat pump increases the value of your property The installation of heat pumps significantly enhances the Energy Performance Certificate (EPC) ratings of buildings in Europe, often improving them by one or two energy classes. This improvement leads to energy savings, increased comfort, and a better environmental profile, which can boost property values or rental fees by 2 to 8%. 2 Projections of savings on energy costs by heat pumps The installation of a heat pump to substitute a natural gas boiler is expected to generate energy savings over 10 years. Energy savings are likely to grow at a steady pace over the years. Daikin Europe conducted simulations to forecast energy prices, considering factors such as historical prices, the European Emission Trading System (ETS), and future carbon taxation. A case study estimated savings for a reference house with a heating demand of 10,000 kWh, showing that using a heat pump can save a total of €2,602 over the decade. 3 Overview of incentive schemes on heat pump technology Although heat pumps may require a higher initial investment than traditional heating systems, they are often eligible for government incentives and premiums. To contrast climate change, many governments are phasing out gas and oil boilers and promoting low-carbon solutions like heat pumps. Historically, convincing homeowners to switch to heat pumps has been challenging, but rising gas prices and the availability of subsidies across Europe are increasing interest and acceptance. These subsidies significantly enhance the competitiveness of heat pumps, accelerating the transition to sustainable heating solutions.
81 4 Overview of a (possible) ban on conventional heating technology The ban on conventional heating technologies (natural gas boilers) is, in many countries, part of the long-term pledge to achieve net zero emissions by 2050. European governments are progressing towards their net-zero emissions goals, with many countries committing to achieve this by setting measurable near-term milestones. One key milestone is the increase in zero-carbon-ready buildings, which means utilising renewable energy technologies like heat pumps and photovoltaic panels or depend on fully decarbonizable energy sources. As part of the REPowerEU plan, the European Commission aims to completely ban stand-alone fossil boilers by 2029 to enhance energy efficiency and accelerate the green transition. 5 Environmental impact of heat pumps Heat pumps are vital for achieving the EU's decarbonization goals. A case study shows that Daikin heat pumps can be 2 to 24 times less carbon-intensive than gas boilers, leading to annual CO2 savings of 0.2 to 2 tons, depending on the electricity grid. The EU Green Deal aims to reduce greenhouse gas emissions by 55% by 2050. With buildings responsible for 40% of energy use and 36% of emissions, heat pumps provide a more efficient and eco-friendly solution. Benefits include high efficiency and reduced fossil fuel dependency, with projections indicating a reduction of 21 billion cubic meters in gas demand for heating by 2030. 6 Synergies among the usage of heat pumps with solar panel (PV) systems A heat pump can enhance the self-consumption rate of a residential photovoltaic (PV) installation by about 10%, yielding annual financial benefits of €80 to €120, depending on energy prices. This is based on a Daikin case study of a 5 kWp PV system and a heat pump with a 250 liter tank in Belgium. Combining heat pumps with PV panels allows households to use free solar electricity for heating and hot water, reducing reliance on gas. As feed-in tariffs decrease across Europe, maximizing self-consumption becomes increasingly important. The heat pump can utilize excess solar energy to heat domestic hot water, effectively acting as an "energy battery" by storing energy for later use.

104 The Quintessence of heat pump meeting modern society's expectations Made in Europe, for Europe European weather can be tough sometimes. That's why we designed the Daikin Altherma 3 H MT & HT. Heating capacities are also maintained high by low ambient temperature thanks to genuine Daikin technology. As the market leader, Daikin is always striving to make the most reliable and efficient heat pumps possible. Daikin developed the Bluevolution technology to achieve higher and greener performance. This technology is now part of all new products. The Daikin Altherma 3 H HT was the first Daikin outdoor unit with a distinctive design. Its single fan reduces the noise level and its black front grille makes the unit fit into any environment. All these dedicated components were developed in-house to make the quintessence of heat pump unique. Superior performance, renewable energy use, design and acoustic comfort. This is what the Quintessence of heat pump is all about. Timeless design and space-saving installation Aside from the acoustic comfort, design is a decisive point nowadays. Specific attention was paid to making the outdoor unit blend in with your home. The black front grille stretches horizontally making the fan inside invisible. The mat grey casing reflects the colour of the wall behind for more discretion. This unit received the IF and reddot design awards 2019. The Bluevolution technology combines a specifically developed compressor and the R-32 refrigerant. Daikin is one of the pioneers in the world to launch heat pumps equipped with R-32. With a lower Global Warming Potential (GWP), the R-32 is equivalent in power to standard refrigerants, but achieves higher energy efficiency and lower CO2 emissions. Easy to recover and re-use, R-32 is the perfect solution to attain the new European CO2 emission targets. Witness a timeless design
105 Silence rhymes with comfort The Quintessence of heat pump has been designed to reduce its acoustic level and meet the expectations of today's society. In standard sound mode, the unit produces a sound pressure of 38 dBA at 3 metres, so somewhere between birds chirping and the inside of a library. The unit also offers greater flexibility by having a low sound mode that reduces the sound pressure at 3 metres to 35 dBA, representing a real reduction of half the sound level! The acoustic level can be evaluated in two ways J The sound power is generated by the unit itself, independently of distance and environment J The sound pressure is the sound perceived at a certain distance. The sound pressure is usually calculated at between 1 and 5 metres from the unit.

106 A redesigned casing The black front grille made of horizontal lines is hiding the fan from view, reducing the perception of the sound produced by the unit. The light grey casing is slightly reflecting the environment where the unit is installed, helping it to blend in in any decor. This unique design already got design awards. Innovation at the heart of our concerns The Daikin Altherma 3 H MT & HT are at top of low sound and heating performances thanks to dedicated developments. Several major components are designed to make this product reach the excellence such as a double injection compressor and a single fan even for large capacity units as well as a brand-new casing. A single fan for all capacities The single fan is slightly larger, replacing the usual double fan for high capacity units (classes 8-10-12-14-16-18). The shape of the fan has also been reviewed to reduce the contact surface with air therefore lower the sound level by improving the air circulation.
107 Compressor insulation and anti-vibration To reduce the compressor sound power, several actions were taken in terms of absorption and insulation. First, the compressor is surrounded by a 3-layer insulation made of air, insulation material and a metal box. Regarding the absorption, the unit benefits from a double sound reduction by using rubber pads between the bottom plate and the vibration plate under the compressor. 35 °C and 55 °C Space heating New double injection compressor To make this product unique, Daikin Europe cooperated with Daikin Japan to develop top notch components. The Daikin Altherma 3 H HT compressor is able to deliver a high leaving water temperature of 70 °C on its own, while the Daikin Altherma 3 H MT available in classes 8-1012 delivers up to 65 °C leaving water temperature. Impressive performance With these new developments, the Daikin Altherma 3 H MT & HT reach the best performances illustrated in the energy labels: Metal box Insulating air layer Insulating material Rubber pads Bottom plate Anti-vibration plate Feel a true performance up to up to +++ D A+++ + F A+
