I’m a plumber in Denver and we are already dealing with the natural gas ban in the city limits. If someone’s gas water heater goes out it’s possible we have to wait up to two weeks to install one. This is after we have to give a detailed explanation as to why we can’t just upgrade to an electric one. If they deny the gas water heater and make us put in an electric one the cost for the homeowner is way more expensive. It’ll be interesting to see how this will all play out.
