Frequently Asked Questions
Which is better for long-term savings: a gas or an electric water heater?
Gas systems typically offer better long-term savings for larger households, especially if hot water is used frequently. However, electric heaters with off-peak pricing can also be economical. UR Plumber helps homeowners make informed decisions based on actual usage and utility rates.
What is the cost of gas vs electric water heater installation?
Electric heaters are generally cheaper to install due to simpler wiring. Gas systems may require extra plumbing, ventilation, and gas line work. UR Plumber offers transparent quotes so you know exactly what to expect before installation.
Do gas water heaters work during a power outage?
Most continuous flow gas water heaters require electricity for ignition and operation, so they may not function in a blackout. However, some models with battery ignition can still operate. Ask UR Plumber about backup-friendly options.
Can I switch from electric to gas water heating?
Yes, switching is possible, but it requires professional installation of a gas line and venting system. UR Plumber can handle the full conversion process and ensure your system complies with NZ safety regulations.
