I have a similar issue with smoke coming out of my kitchen heater every time I cook. Does anyone know what it could be? I hope the heater is fine as I am getting a guy from supremeductcleaning.com.au to come and clean the ducts in the house and some of them can look at all the issues the heater might have. It will be good to know that as well. last year one of them came to clean the HVAC filters and found a lot of issues that were able to be fixed. Now if he is going to see my heater and tell me what's the best solution would be amazing.
