Councillor Lyall Thurston said the old wood burners contributed to health issues.
"Our most vulnerable are being affected by these old fires and everybody in the community has to do their part if we are going to fix this issue."
Toi Te Ora Medical Officer of Health Dr Phil Shoemack said smoke from household fires had a major effect on health.
"Smoke affects how our lungs work and is a particular concern for young children, the elderly and people with underlying lung conditions like chronic bronchitis and asthma.
"Every household that converts to a clean source of heating contributes to improving air quality across Rotorua and to the health of everyone in our community."
The council has two schemes set up to help residents replace heating in their homes.
The Hot Swap Scheme sees the appliance supply and installation costs added on to a property's rates to be paid back over 10 years. Some loans are interest-free and some are interest-bearing.
The Low Income Heating Grant helps homeowners with limited means to upgrade an old fire. To qualify for the grant the household occupants must have a combined annual household income of $50,000 (gross) or less.
