FAQs
What size tank water heater is right for my Mascot home?
Sizing depends on how many people live in the home and when hot water is used. As a rule of thumb, a 2-person household usually needs a 125–160 L electric storage or a 90–135 L gas storage unit. Families of 3-4 often choose a 160–250 L electric or 135–170 L gas model, while larger families may need 250 L+ electric or 170 L+ gas. We also look at simultaneous uses—showers, washing machine, dishwasher—and whether you are on off-peak tariffs. Our licensed plumbers can calculate peak demand and advise the most economical size during a free site inspection.
Which tank-type water-heater brands do you supply and recommend?
For Mascot residents we stock and install Australia’s leading brands, including Rheem, Rinnai, Dux, Vulcan, Aquamax and Thermann. All meet Australian Standard AS 3498 for potable water and come with manufacturer tank warranties ranging from 5 to 12 years. We’ll match the brand to your budget, fuel source (natural gas, LPG or electric) and space constraints, and we carry most common models on our service vehicles for same-day replacement.
How long does a storage water heater last and when should I replace it?
Most steel-tank electric units last about 8-12 years and gas models 10-15 years in Mascot’s mildly hard water. Replace the heater if you notice rusty or discoloured hot water, rumbling noises from sediment build-up, water pooling around the base, or frequent pilot/element failures. If the unit is over 10 years old, replacement is usually more cost-effective than major repairs because newer heaters are far more energy-efficient and still under warranty.
Are there energy-efficient options or rebates available in Mascot?
Yes. High-efficiency gas storage units (5-Star), heat-pump and solar-ready storage tanks can cut running costs by up to 60 %. Under the NSW Energy Savings Scheme (ESS) and federal STC program you may be eligible for rebates when upgrading from an older electric unit to an approved high-efficiency model. We handle all paperwork, calculate the rebate on the spot and deduct it from your invoice.
How quickly can you repair or replace a faulty tank water heater in Mascot?
Because our depot is only minutes from Mascot, we offer same-day service when you call before midday and 24/7 emergency call-outs with an average onsite time of 1 hour. Our vans carry common thermostats, elements, valves and complete 50 L–315 L tanks, so in most cases we restore hot water on the first visit.
What maintenance does my tank water heater need to stay safe and efficient?
1. Test the temperature & pressure relief (TPR) valve every 6 months to prevent over-pressurisation. 2. Drain a few litres from the tank annually to flush sediment that reduces efficiency. 3. Have a licensed plumber inspect or replace the sacrificial anode every 3–5 years; Mascot’s mineral content can corrode tanks if the anode is spent. 4. Check the tempering valve delivers 50 °C water to outlets while the tank is stored at 60 °C to control Legionella. 5. Confirm the pressure-limiting valve is set below 500 kPa (the NSW maximum). These simple tasks can extend the life of your heater and keep energy bills in check.
