Report Description

Solar Water Heater Market was valued at US$ 3 billion in 2020 and is expected to grow at a CAGR of 7% over the forecast period (2021-2027). Solar water heating is a reliable, clean, and cost-effective technology which can save utility bills for thousands of homes and businesses. This technology works by capturing sunlight to produce electrical and thermal energy. This alternative energy source can typically be converted into heat which provides hot water to heat homes and businesses. Solar water heating systems utilize solar thermal heating to deliver hot water in many countries around the world. The most important aspect of this technology is that it can reduce our reliance on fossil fuels. Solar water heating collectors are used to trap solar energy. These collectors are typically then connected to glazed on unglazed water systems. A typical solar water heating system can save up to 1500 units of electricity every year i.e., for every 100 liters of solar heating capacity per day.


The key factors influencing the market growth include the increasing demand for cost-effective and eco-friendly solutions. As solar water heaters work on zero emissions and zero consumption of fossil fuels principle it is gaining traction among the eco aware consumers. Sun shining on a 1 m2 roof can replace 100 liters of heating oil or 100 m3 of natural gas. Additionally, government rebates on solar equipment’s including in solar water heating systems is also increasing the demand of solar water heaters. For example, In Victoria, Australia all residents and commercial areas can get rebate up to US$ 700 depending on the type and size of the system installed. In the long run, solar water heaters are even cheaper than other types of water heaters as they save on years of electricity and maintenance costs. Key drawback of solar water heaters is their working in cloudy weathers, however good backup systems can make that possible.

Insights Presented in the Report

“Amongst Type, Glazed segment holds the major share”

Based on type, the solar water heater market is segmented into glazed and unglazed. The glazed segment is further segmented into evacuated tube and flat plate. Amongst type, the glazed segment of the market was valued at US$ XX million in 2020 and is likely to reach US$ XX million by 2027 growing at a CAGR of XX% from 2021-2027. Glazed solar collectors have selective coating on them usually made up of aluminum plate or copper and they also have an iron tempered glass covering. This makes glazed solar water heaters 14% more thermal efficient than unglazed water heater according to a study comparing the two.

“Amongst System, Thermosiphon Segment holds the major share”

Based on system, the solar water heater market is segmented into thermosiphon and pumped. Amongst system, thermosiphon segment accounted for a market valuation of US$ XX million in 2020 and is expected to reach US$ XX million by the year 2027, at a CAGR of XX% over the analyzed period. A thermosiphon solar water heater relies on the phenomenon of rising warm water. Thus, it is installed above the solar collector and the water warms and rises to the tank which is then collected and flown down the pipes.



“Amongst End-User, Residential Segment holds the major share”

Based on end-user, the solar water heater market is segmented into residential, commercial, and industrial. the commercial segment is further divided into educational institutes, offices, government buildings, and others. The residential segment generated revenue of US$ XX million in 2020 and is expected to grow at a CAGR of XX% during the forecast period to reach a market valuation of US$ XX million by 2027F. Solar water heater can be used in residential homes for cleaning, washing, and bathing purposes. Typical capacity used in residential segments are the 100-300 liters solar water heaters. As compared to an electric geyser, solar water heaters typically save 1500 units of electricity per year and additionally prevent 1.5 tons of carbon-dioxide per year.

“Asia Pacific represents one of the largest markets of Solar Water Heater market”
