LPG vs electric hot water system

There are lots of options when it comes to LPG vs electric hot water heater products. Most of us take hot water for granted and don’t give it much thought until it’s time for repairs or an upgrade. There are several factors worth considering prior to choosing a hot water system for your home.

  • How much water do you use during an average day or week?
  • How large is your household?
  • How many bathrooms are there?

Here’s a comparison of electric hot water cylinders, gas hot water cylinders and gas continuous flow hot water to help you decide the best hot water system for your home.

PROS of Electric Hot Water Cylinders

  • Some models can be installed indoors or outdoors
  • Some newer models are triple insulated to minimise heat loss

CONS of Electric Hot Water Cylinders

Cost efficiency: LPG vs electric hot water systems

Running costs account for the majority of the household power bill so it’s important to choose the right energy source and appliances for your home. Both natural gas and LPG have advantages such as producing less greenhouse gas emissions compared to electric systems. In areas where the natural gas line isn’t available, LPG is a worthy alternative. Whether you are building a new home or retrofitting an old one, LPG could suit your energy needs.

Using gas for hot water and home heating can cost less than using electricity. The price advantage is increased when using gas for both water and home heating. The more energy used, the greater the potential for savings by using gas. The benefits of gas over other forms of heating include health benefits, efficiency, running costs and lifestyle improvements.
