Gas Hot Water in Auckland: Benefits, Costs, and Installation Process

Installing a gas hot water system can be a great option for many Auckland homeowners looking to update their hot water supply. Gas systems provide reliable and efficient hot water on demand with many benefits over traditional electric or solar systems.

This article will outline the main pros and cons of gas hot water in Auckland, typical costs and considerations for installation, and provide an overview of the installation process.

Benefits of Gas Hot Water

There are several good reasons why more Aucklanders are choosing gas to fuel their hot water systems:

  • Efficiency – Gas water heaters tend to be more energy-efficient than conventional electric storage units as they only heat water on demand rather than constantly maintaining a whole tank of hot water. This saves on energy bills.

  • Lower running costs – With recent increases in electricity prices in NZ, gas hot water is becoming a cheaper option per liter of hot water produced. Homeowners can achieve 10-35% savings on water heating costs by switching from electric to gas.

  • Continuous hot water – Gas systems provide a limitless flow of hot water on tap rather than running out if a storage tank hasn’t sufficiently reheated. Great for larger households.

  • Environmental benefits – Modern gas heaters produce less greenhouse gas emissions than using electric off the centralized power grid powered predominantly by fossil fuels.

  • Long lifespan – New gas hot water systems normally last 15-20 years with basic maintenance, longer than electric alternatives.

Costs and Installation Considerations

Typical costs for installing a new gas hot water system in an Auckland home range from $2000-$4000 depending on the unit size, brand, accessories needed, difficulty of installation etc. Always get all-inclusive quotes from qualified gasfitters. Factors impacting install costs include:

  • Main gas line connectivity – Homes without existing gas supply will need a gas line installed from the street adding $1000+ to costs.

  • Fluing arrangements – Flue vents may need installing for ventilation, increasing labor and parts costs.

  • Condensate drainage – Building regulations require proper drainage under the unit for condensation collection. Complex plumbing can raise prices.

  • Access issues – Difficult access to installation site like upper floors can mean more labor time to transport equipment and interconnect gas, water and electrical connections.

  • Brand and unit size – Higher volumes, higher pressures and more advanced models provide better performance but increase supply expenses.

Installation Process Overview

The full installation process typically is completed within a day into a couple of parts:

Part 1:

  • Removal of old system & preliminary gas supply connections

  • Structural modifications if needed for new unit dimensions/weight

  • Install mounting frame, plinths and inter-connections for gas, water, electricity & fueling

Part 2:

  • Install water heater unit and finalise pipe & valve fittings

  • Pressure test gas supply integrity

  • Commission unit, preset controls and activate water/gas supply

  • Demonstrate function and safety features to homeowner

  • Provide compliance certificate & warranted documentation

Choosing both the right unit and professional installer are equally important for ensuring years of reliable hot water delivery, safety, efficiency and fast servicing backup when required. Consult licensed gas engineers like Hot Water Solutions to review your household requirements.
