Decision Guide

Should You Repair
or Replace Your Thermann?

Not sure whether to fix or upgrade? Use our guide to make the right call.

R

Repair is the smart choice if…

  • System is under 8 years old
  • Single, isolated fault identified
  • Energy bills are still reasonable
  • No recurring breakdowns in past year
  • Fault is a sensor or minor component
U

Upgrade makes sense if…

  • System is 10+ years old
  • Multiple faults in the past 2 years
  • Compressor or PCB failure (major cost)
  • Energy bills have risen significantly
  • R22 refrigerant (phased out, illegal to recharge)
Not sure which applies to your system?
Our technicians provide a free honest assessment. We never recommend replacement unless it genuinely makes sense for you.

Safety First

Carbon Monoxide &
Gas Safety — What You Need to Know

Carbon monoxide (CO) is colourless, odourless, and potentially fatal. Gas-powered Thermann systems can produce CO if they have a cracked heat exchanger, blocked flue, or faulty burner. Victorian regulations require annual CO testing for rental properties.

Headaches, dizziness, or nausea when heater is on
Yellow or orange flame instead of blue
Excessive condensation on windows near the unit
Sooty or dark marks around the heater
CO Safety Checklist
Annual CO test by a certified technician
Flue and heat exchanger inspection
Carbon monoxide detector installed nearby
Adequate ventilation around the unit
No signs of soot or yellow flame

Fixed Our Thermann at Midnight

Our ducted Thermann died on the coldest July night. The team arrived in 3 hours with genuine parts and had us warm by midnight. Absolutely incredible.

Spotless Thermann Installation

Upgraded to a Thermann Zena. The installation was immaculate — they protected our floors, cleaned up, and even set up remote control access for us. True professionals.
