National price ranges
FireAvert $250; CookStop $385 (accessed listing prices).
When it is worth it
- Memory changes and the person still cooks.
- A pan has been left on before, or smoke alarms have gone off while cooking.
When to try something else first
- The person no longer uses the stove: the Alzheimer's Association suggests knob covers, removing knobs or turning off the gas instead.
What moves the price
- Electric (plug-in) versus gas (needs a gas valve and a pro).
- Monitoring subscriptions that alert family.
DIY or hire it out
Plug-in units for electric ranges are DIY if the range plug is reachable; gas models need a licensed installer.
Where this shows up in the home check
Keepstead suggests this fix when one of these checks fails. Run the home check to see whether it is a priority for your home.
- The stove turns itself off, or there is no risk of it being left on (kitchen)
Frequently asked questions
Do stove shut-offs work on gas stoves?
Some models do, using an automatic gas valve, but they need a licensed installer.
What can I do for free?
Knob covers, removing knobs when not in use, or turning off the gas supply at the valve, as the Alzheimer's Association suggests.
