Restraining Factor

High Initial Cost and Complex Installation Process to Potentially Impede Market Growth

However, the market growth is mainly impacted by the several inhibitors such as costlier upfront installation price coupled with complicated installation procedures. AWHP systems are more expensive than typical heating systems in terms of the initial procurement of equipment, upgrading infrastructure and professional installation. For example, additional components like buffer tanks, the means for underfloor heating, or larger radiators are necessary to achieve the same efficiency of operation by adapting the system to existing radiators or remodeling old buildings. This results in both material and labor expenses. In many areas, particularly in emerging countries, consumers as well as businesses are reluctant to use AWHPs, especially because of financial constraints or limited subsidy opportunities. And even though the money is recouped long-term on energy bills, the payback period can also seem long. Installation also depends on expertise technicians and although the availability of trained personnel can delay deployment, it can also result in unwise installations. These obstacles are especially formidable in rural locations and in low-income urban housing. Consequently, while awareness and application of the air-to-water heat pump is rapidly increasing, its use remains limited in price-competitive markets, discouraging overall market development.

Government Incentives and Green Building Regulations to Create Opportunity for the Product in the Market

Opportunity

The key opportunity that is propelling growth of air-to-water heat pump (AWHP) system market is the growing government support in terms of incentives and the imposition of green building codes.

Here, for instance is the European Union Green Deal, the UK peace for Boiler Upgrade Scheme, and Japan zero-energy home programs, where homeowners together with commercial users are provided financial support after switching to a sustainable heating system.

At the same time the building codes are being revised to require or encourage the use of low-emitting systems, especially in new constructions and the retrofit market. To meet the energy-efficiency targets, AWHPs are becoming part of urban infrastructure projects, smart cities and public housing schemes. This attractive regulatory environment not only helps to minimize initial costs for end users but also triggers innovation and competition between those who manufacture it. With more stringent climate targets and increasing carbon constraints globally, these policy-led opportunities could provide long-term demand and market growth potential for AWHP systems.

Installation Complexity and Infrastructure Limitations Could Be a Potential Challenge for Consumers

Challenge

However, complex installation and requirement for compatible infrastructure are likely to deter the growth of the air-to-water heat pump (AWHP) system market to a certain extent. AWHPs often need to be heavily retrofit into existing heating systems, especially older ones with traditional radiators or pipe arrangements that are not well-suited to low-temperature heat pumps. It requires the retrofit structure to be re-tooled for the new use, as well as extra equipment, additional space and professional judgment--and obviously adds both time and cost for end-users. In addition, consumers in most cases will have to improve their insulation, or take on the cost and disruption of installing underfloor heating to reap the full advantage of AWHP efficiency which isn’t always feasible both from a practical and a financial point of view.

Furthermore, specialist training is not available widely in many developing regions so installations are carried out poorly and systems fail to function to their potential. When for commercial or industrial use, compact system designing and planning is necessary to combine with boilers or HVAC systems. This infrastructure complexity is a barrier to deployment in areas with less awareness, technical capabilities, or discretionary spend on modernization. These integration and compatibility challenges must be addressed to achieve the greatest deployment potential of simulation-based design for AWHP systems in a wide range of residential and commercial building types.
