When a coal-fired power station or a gas-fired gas furnace starts to leak CO2, the problem can be deadly.
The fuel can leak out of the exhaust pipe, into your water heater, or into the air vent.
But the only way to fix it is to replace the coal gas boiler.
It takes about a week for the boiler to cool, and after that, it can take up to three months for the fuel to return to normal.
But it is much easier to fix this problem if you have a CO2 detector installed on your home.
If you’re not sure if your home has one, here are some of the common ways you can check if the boiler is leaking: If you see signs that the boiler isn’t cool, you can turn off the gas and vent to see if the air conditioning is working.
