FAQs
How long does a tank water heater usually last in Mascot’s conditions?
With Mascot’s mild coastal climate, a quality vitreous-enamel or stainless-steel storage tank will generally last 8–12 years if it is installed correctly and serviced every 5 years. Water hardness, usage patterns and maintenance all influence life span. Our licensed plumbers check sacrificial anodes, temperature & pressure relief valves (TPRs) and insulation to maximise service life.
What size storage tank should I choose for my household?
Sizing depends on the number of occupants and simultaneous hot-water activities. As a rule of thumb, allow 30–50 L per person per day. A one-bedroom unit might only need a compact 50 L unit, while a family of four in a Mascot terrace home typically opts for a 250 L electric or 135 L gas system. We also consider peak/off-peak tariffs, space constraints and any future renovations before finalising a recommendation.
Can you replace my old unit with an energy-efficient model on the same day?
Yes. We keep popular Rheem, Rinnai and Dux storage units in stock at our Rosebery warehouse, 5 minutes from Mascot. When you call before 10 a.m., we can remove the existing heater, upgrade pipework to AS/NZS 3500 standards, fit tempering valves and commission the new system that afternoon, subject to gas or electrical compliance checks.
How much will a standard tank water heater installation cost?
For a like-for-like electric storage replacement in Mascot, costs start around $1,100 incl. GST, which covers the unit, plumbing materials, labour, old unit disposal and SafeWork NSW compliance certificate. Gas storage replacements begin at roughly $1,450. Prices rise if a tempering valve, new isolation valves, pressure-limiting devices or switchboard upgrades are required. We provide fixed quotes after a brief site inspection.
What ongoing maintenance does my storage hot-water system need?
Every 5 years (or as per the manufacturer’s manual) we recommend: • Draining and flushing the tank to remove sediment. • Replacing the sacrificial anode (for enamel tanks). • Testing and, if necessary, replacing the TPR valve to prevent over-pressurisation. • Checking for corrosion, leaks and insulation degradation. Routine maintenance keeps energy bills down, prolongs tank life and is a requirement for most warranties.
Do you handle warranty repairs and council compliance paperwork?
Absolutely. We are authorised service agents for major brands and can lodge warranty claims on your behalf. After any installation or major repair, we issue a completed Certificate of Compliance (CC) to satisfy City of Bayside Council and NSW Fair Trading requirements, ensuring your home insurance remains valid.
