Gas Hot Water System Installation Cost

Gas hot water systems offer several strong advantages. They deliver fast, reliable heating and can replenish hot water quickly, making them ideal for larger households with high water usage. Gas systems typically have lower running costs compared to electric models, especially where natural gas is readily available. They are also less affected by power outages, providing a more consistent supply. Continuous flow gas systems (instantaneous) are especially energy-efficient, as they heat water only when needed, reducing energy wastage. With a wide range of sizes and types available, gas hot water systems offer flexibility, efficiency, and great long-term value.

Gas hot water systems generally sit mid-range in terms of both upfront and ongoing costs. Installation is often slightly more expensive than electric systems (averaging between $1,200 and $2,500 installed) but cheaper to run over time due to lower gas prices. In contrast, electric systems are cheaper initially but can lead to higher energy bills, while solar systems have the highest upfront cost but offer the greatest long-term savings. Overall, gas systems strike a smart balance for many households: affordable to install and cost-effective to operate.

Yes, safety is critical when installing a gas hot water system. Key precautions include:

• Licensed installation only — Only licensed gas fitters should install gas systems.

   

• Proper ventilation — Ensures safe dissipation of gas emissions.

   

• Correct gas pressure testing — Verifies all connections are sealed and secure.

   

• Flame failure devices — These safety features automatically shut off gas if the flame goes out.

   

Local compliance checks — Installations must meet all relevant building and safety codes.
