Hot Water Plumber
Sutherland Shire

No hot water? We carry electric, gas and heat pump units in the van. Most jobs replaced same-day. Federal STC rebate handled in-house — you pay the discounted price, we deal with the paperwork.

Repair vs Replace

When does each make sense?

  • Under 8 years old + fault is thermostat/element/anode/valve → repair almost always wins ($200-$400)
  • 8-12 years old → tank leak = replace; element/anode = repair if you want 2-3 more years
  • Over 12 years or leaking from tank → replace. Most warranties have expired

We show you the age stamped on the data plate and give both options with prices before you decide.

FAQ

Hot water questions

How much does a heat pump cost in the Shire after the rebate?

Typical installed price after the STC rebate is $3,000-$4,500 for a 270L unit suitable for a family of 4. Sticker price $4,500-$5,500; rebate $800-$1,200 off.

How long does it take to replace a hot water system?

Most electric and gas swap-outs are 2-4 hours. Heat pump installs are 4-6 hours because of the outdoor unit and pipework.

Will you take the old unit away?

Yes — removal and disposal included in the install price.

Heat pump vs gas — which is better?

Depends on your situation. Mains gas + average usage → gas instantaneous wins on upfront. No gas, or want lowest running cost over 10 years → heat pump. We'll talk it through on-site with your actual numbers.

My hot water is just lukewarm — what's wrong?

Usually a failed element or thermostat. We diagnose on-site in 15-20 minutes and replace the same visit if we have stock (we usually do).
