Choosing Hot Water Systems: Electric VS Gas VS Solar

Choosing the right hot water system for your home is an important decision that can impact your comfort, energy efficiency, and environmental footprint. With various options available, including electric, solar, and gas systems, it’s essential to weigh the pros and cons of each to determine which one best suits your needs. In this blog, we’ll explore the differences between electric, solar, and gas hot water systems to help you make an informed choice and ensure appropriate residential plumbing!

Electric Hot Water Systems

Electric hot water systems are among the most common options for households, offering convenience and affordability. These systems use electricity to heat water, typically through an electric element located inside a storage tank. One of the main advantages of electric hot water systems is their relatively low upfront cost compared to other options. They are also easy to install and compatible with most homes, making them a popular choice for both new construction and existing properties. Although these tanks are among the most economical solutions available and come in a variety of sizes, it must be acknowledged that they are not the most energy-efficient hot water system available.


  • Low initial expenses
  • Reliable
  • Heat in off- peak times
  • Simple to install


  • Costly in the long run
  • Using non-renewable energy sources is not environmentally beneficial.

Gas Hot Water Systems

Gas hot water systems use gas to heat water, offering a reliable and efficient option for households connected to gas mains. These systems heat water on demand, eliminating the need for a storage tank and ensuring a continuous supply of hot water whenever needed. Gas hot water systems are known for their fast heating times and high efficiency, making them suitable for households with high hot water demand. One of the main advantages of gas hot water systems is their lower operating costs compared to electric systems, as gas is typically cheaper than electricity for heating water. Additionally, gas hot water systems produce fewer greenhouse gas emissions than electric systems, making them a more environmentally friendly option for eco-conscious homeowners.


  • Fewer emissions of greenhouse gases
  • Compared to electricity, generally have lower usage rates (depending on your area)
  • Long-term cost effective
  • Accelerated heat recovery times


  • Only really functional when linked to a gas main (using LPG bottles is very expensive)
  • It must be outside (or exhaust fan inside)
  • Can quickly lose heat due to inadequate insulation

Solar Hot Water Systems

Solar hot water systems harness the power of the sun to heat water, offering a renewable and environmentally friendly alternative to traditional electric or gas systems. These systems typically consist of rooftop solar collectors that absorb sunlight and transfer heat to a storage tank, where the water is stored until needed. One of the key benefits of solar hot water systems is their reduced reliance on grid electricity, resulting in lower energy costs and carbon emissions. By utilising free energy from the sun, solar hot water systems can significantly reduce household energy bills over time, making them a cost-effective choice in the long run.


  • Fewer greenhouse gases
  • Reduced energy costs
  • Qualified for several rebate programmes
  • Energy independence
  • Installable practically anyplace, provided there is adequate room, and requires almost no maintenance


  • High initial expenses
  • Lots of room is required for the system.
  • Cloudy days don’t generate a lot of energy
  • Decreased production during the winter
