Heat Pump Water Heater Market Trends

Burgeoning Eco-friendly Initiatives to Stimulate Demand for Heat Pump Water Heaters

Hot water is an everyday requirement for modern living. Traditionally, water is heated through burning fossil fuels or using electric heaters. These methods of water heating work at an energy efficiency of less than 1, which means that the heating delivered is less than electrical energy or fuel used. Increasing energy prices of gas or oil heating systems, along with the need to meet CO2 emission targets, have caused interest in the dedicated growth of heat pumps. In preference to burning fossil fuels to produce heat and continuous CO2 emissions, dedicated heat pumps utilize renewable energy from the environment, such as air, ground, and water. The consumption of primary energy is up to 70% less, hence a drastic reduction of pollution resulting from the use of fossil fuels.

Heat pumps available in the market showcase a 3-5 times higher energy efficiency compared to natural gas boilers. This technology not only minimizes households' exposure to fluctuations in fossil fuel prices but has become increasingly crucial amidst the ongoing global energy crisis. Heating in buildings accounts for about one‐sixth of the world's natural gas demand, rising to one‐third in the European Union. Many heat pumps are multifunctional, offering both heating and cooling capabilities. This decreases the need for a separate air conditioner for a significant portion of the population residing in areas requiring both by 2050. Opting for heat pumps over fossil‐fuel‐based boilers substantially slashes greenhouse gas emissions across major heating markets, even with the current electricity generation mix. This advantage will only grow as electricity systems transition toward decarbonization.

Heat Pump Water Heater Market Growth Factors

Lower Operating Costs and Efficient Operation of Heat Pump Water Heaters to Drive Market Growth

The accelerated deployment of heat pumps brings a range of benefits. Increasing demand for heat pumps to save consumers’ money and shield them from price shocks is driving market growth. The average household or business that uses a heat pump expends less on energy than those utilizing a gas boiler. These energy savings counterbalance the higher upfront costs for heat pumps in many markets today, in some even without subsidies. The economic proposition of heat pumps improves in the context of today’s energy price spikes, with household savings ranging from USD 300 per year in the U.S. to USD 900 in Europe. With appropriate support for poorer households to manage the upfront costs, heat pumps can meaningfully address energy poverty, with energy bill savings in low‐income households ranging between 2% and 6% of their household revenue after moving away from a natural gas boiler.

Water heaters stand as the second most significant energy consumer in homes, following heating and cooling systems. The adoption of new energy-efficient heat pump technology in water heaters proves to be an exceptionally effective method for heating water, resulting in reduced energy consumption and cost savings on utility bills compared to conventional electric resistance water heaters. In contrast to standard electric models, (HPWH’s) exhibit three times the efficiency. They also outperform gas water heaters, which experience energy loss during the venting process, boasting efficiencies three to four times greater than traditional gas water heaters. Stringent governmental regulations aimed at reducing emissions from HVAC equipment in both residential and commercial sectors contribute to advancing the perception of this technology. Furthermore, advancements in technology enable users to personalize settings based on daily, weekly, or monthly needs and even control temperature settings via a mobile app.

Growing Focus on Energy Efficiency and Decarbonization to Boost Market Expansion

Electricity use and power will increase when heat pumps, both air-to-water and ground-source heat pumps, are used for heat sources in new residential buildings compared to heating solutions that do not use electricity. There is a spiralling demand for (HPWH’s) in residential buildings as the application of high-performance insulation reduces hourly peak power in different buildings relative to the minimum insulation. In apartment buildings, high-performance insulation compensated for about half of the additional electric power when buildings with heat pumps were compared to district heating. In this scenario, the application of high-performance insulation will fully compensate for the installation of heat pumps in all apartment buildings. Preference for ground source heat pumps over the air to water heat pumps would further reduce the electricity power needed.

Commercial hot water system requirements can be larger and more demanding than residential systems, and some manufacturers are bringing these higher-output heat pump systems to the market. North America and Asia Pacific are retrofitting heating and cooling equipment across buildings to meet their emission targets. Depending on the type of business, there are specific resources to assess the options, such as commercial resources from the Department of Energy and the Environmental Protection Agency. Some residential integrated HPWHs are equipped with the ability to link with the electricity provider through a device that supports the EcoPort communication standard but has not yet been prevalently adopted for larger commercial integrated HPWHs, nor has a corresponding alternative been established. These could be controlled through a building automation system and could be programmed to respond to demand response signals from a utility. Even the government has a long-term vision to decarbonize the electric grid, which will require market transformations for both the residential and commercial sectors.

RESTRAINING FACTORS

Higher Upfront Costs of Installation of Heat Pump Water Heaters Hampers their Adoption

High upfront costs can discourage consumers despite long‐term savings. The expense of purchasing and installing an air‐to‐air heat pump is usually between USD 3,000 and USD 6,000. However, even the cheapest air‐to‐water models, including modifications to the existing radiator systems, remain two to four times more expensive than natural gas boilers in major heating markets. Financial incentives are currently available in over thirty countries around the globe, covering more than 70% of today’s heating demand. The subsidies in these countries provide the cheapest heat pump options comparable to the cost of a new gas boiler for consumers. Additional incentives can target low‐income households (as in Poland) or high-efficiency models (as in Canada). In some countries, the design of electricity tariffs and energy taxation put heat pumps at a disadvantage relative to fossil fuel boilers. Tariffs and taxes should instead be tilted in favour of cleaner and more efficient consumer choices.

Regardless of the type of property, the upfront capital cost for installing a heat pump today is particularly higher than for hydrogen-ready boilers, and this discrepancy increases once home upgrades such as energy efficiency measures and new heat distribution systems are required. There are several costs facing consumers looking to upgrade their home heating systems from existing gas boilers to low-carbon alternatives. These include costs associated with the capital cost of the new heating system depending on the choice of Ground source heat pump (GSHP), Air source heat pump (ASHP), or Hydrogen hybrid heat pump (HHHP). Secondly, potential energy efficiency measures, such as solid wall insulation, cavity wall insulation, loft insulation and more, are also new heat distribution measures. The upfront capital cost, therefore, increases for heat pumps when we consider the need for these additional measures, and these will naturally vary across property types depending on their existing level of energy efficiency.
