Gas heater servicing questions

While many consider the home to be a place of safety and comfort, there are a wide range of risks involved for those working in a home environment and we all have an obligation under the Workplace Health and Safety Act 1995 to provide a healthy and safe workplace for workers in the workplace including in private homes.

Please no pets in work area as it is usually safer to place your pets in another area for a short time while the technician is onsite for their safety. There may be sharp edges on dismantled heaters that could cause injury to your pet and pets can sometimes inadvertently get underfoot or hinder the technician in working quickly and safely.

  • Please provide a clear work area (enough area for tool boxes and for the heater to be dismantled)
  • Please maintain a safe work environment.
  • No pets in work area please.
  • Please consider parking & access
  • Please open blinds if possible so as to provide adequate lighting for the technician
  • Please inform workers of any known hazards(e.g. any known faulty electrical equipment)
  • Please cooperate with workers to ensure safe work procedures and a safe work environment (e.g. move furniture to allow adequate work space based on assessed needs)
  • Please advise the technician of any in-home safety devices and their location (e.g. any isolation, safety switches and switchboards)
  • Communicate and understand what services are to be provided
  • Conduct a 5 point risk assessment
  • If the assessment shows that workers are exposed to significant risks, service providers will determine whether they need to modify or suspend that particular service until the risk has been adequately controlled. 
  • Wear personal protective equipment (PPE) and be trained in its use
  • Assess additional services before being performed  
  • Review an activity that may have changed to ensure the controls are still working or need to be altered
  • Document the daily monitoring of the service

Most manufacturers recommend for their gas heaters to be serviced either on a 1 or 2 yearly basis. Our service technicians can recommend a service schedule for your gas heater based on manufacturers requirements and our years of experience. If you have not had your gas heater serviced for many years it is recommended to get it checked firstly for safety and also on many occasions we can pick up a minor problem during a service that can avoid an expensive fix when something break down causing faults on other components.

Quite often there are minor faults that can be identified and rectified during a Standard Service schedule of your gas heater which can avoid expensive repairs. Should your gas heater require repairs our fully equipped vans carry a large range of gas spare parts to get your heater up and going again.

Laboratory testing suggests that all gas heaters can produce potentially hazardous levels of carbon monoxide. 

Carbon monoxide poisoning typically occurs from breathing in too much carbon monoxide (CO). Symptoms are often described as “flu-like” and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion. Large exposures can result in loss of consciousness, arrhythmias, seizures, or death.  

It is critical that your appliance is checked and recorded by a licensed gas fitter for combustion product spillage every 2 years, (or earlier if recommended by manufacturer) after servicing or repairs, or after alterations to the building that may negatively impact the building’s ventilation, including the installation of exhaust fans.

Protec Gas Services does not give legal advice and it is your obligation to seek your own legal advice in matters pertaining to rental law, your obligations and responsibilities, yet it is our view and understanding that common law dictates that landlords have a duty to guarantee the safety of their rented property and its contents. Of utmost importance is that no injury or damage is caused to the tenants, neighbours or public as a direct result of the landlord neglecting his/her responsibilities. In addition to common law there are regulations specific to rental properties in each State or Territory. 

The SA Government Using Gas Safely Carbon Monoxide web site suggests the following:


“Faulty or poorly maintained gas appliances present a very high risk of causing carbon monoxide poisoning of the people in your home.”

“If you have a gas appliance in your home, or you are a landlord who rents out homes with indoor gas appliances, ensure they are serviced every two years to minimise the risk of faults occurring.”

Gas Heater Servicing & Repairs Explained

Gas heaters require regular servicing on a 1-2 year basis. Most manufacturers require that their heaters be serviced annually. 

Most gas heaters when serviced regularly, and as the manufacture recommends, only require a Standard Service including safety checks to maintain safe and efficient operation. Gas heaters generally only require Extended Servicing and or repairs as required.

A STANDARD gas heater service comprises of tests and checks and minor clearing to ensure important safety points are covered, possible faults are identified early to ensure the safe and  efficient operation of the heater.

An EXTENDED gas heater service includes all the points covered in the Standard Service PLUS clearing out of debris and buildup from the heater and components that may have become obstructed through extended periods of non servicing  or operation in high debris buildup prone situations. 

Repairs are carried out when components are identified as being faulty or in need of replacement to ensure the efficient and safe operation of a gas heater. The cost of replacement components are not covered in the price of a service and are to be identified and priced individually. While repairs are not not covered in a standard service schedule they may be included should extended time to fit new component/s not be required.

As there are many gas heaters in the market of differing design and accessibility we must individually approach each heater based on manufacturer requirements and by the specific internal operational components and condition of each individual gas appliance. All servicing and repairs conducted include required documented safety checks with certified electronic gas detecting equipment by fully trained and certified technicians.
