Diesel Heater Servicing

Diesel Heater Servicing

Dieselheat is one of the few businesses in Australia specialising in service and repair of diesel heaters, cookers and hydronic furnaces.

We have a full suite of diagnostic equipment for Wallas, Eberspacher, and Belief diesel heaters and we carry spare parts for all these brands.

If your diesel appliance has stopped, before you contact us, it is worth running through the procedure on our diesel heater fault finding page as many issues can be resolved without sending your heater for service.

Fixed Price Servicing

For common heater types we offer fixed price servicing, this includes:

-Diagnosis / problem identification via diagnostic computer and test run

-Standard service including full strip down, cleaning, genuine service kit and reassembly

-Test run, checking and emissions analysis

-Service report with hours run, CO and CO2 emissions.

-Packaging and express post return freight

-Re-install instructions, post service support and advice

For servicing prices please call us.

We also work with a small number of other like minded companies in other states who provide dedicated servicing and who we know have the necessary equipment and expertise to properly service your diesel gear. We share parts and technical support with these companies, so for local support they are our recommended partners. For anything related to warranty for a product sold by Dieselheat – please contact us first.

4 Easy Steps to Get Your Diesel Heater, Hydronic Furnace or Cooker Serviced

1. Contact Dieselheat or one of our service partners

We will have a quick chat with you to make sure your diesel heater / cooker / hydronic furnace is serviceable and your problems are not related to the installation.

2. Remove the Item

To get your item serviced or repaired we only need the item itself plus ideally the fuel pump, no controllers or wiring need to be sent. If you need help removing the item contact us or our service partner.

3. Post us the Item

If it’s a diesel heater or hydronic furnace, post it in a post bag (costs less than $20) to Dieselheat at 39 Golden Valley Road Cygnet TAS 7112 or to our service partner. Make sure your contact details are included and a note describing the issue.

4. Fix and Return

Once the item is received you will be contacted to discuss its problems before the repair or service are undertaken.

After an item is serviced it will be returned fully tested with a certificate showing its test results and flue gas emissions to demonstrate it is running properly.
