Most natural gas space heating involves a blower fan of 500W or more.
We don’t know exactly how much leaks, but the estimates have been growing and most sources cite 2-4%. Given the 80x multiplier on methane as a GHG compared to CO2, that’s potentially a really big problem.
One of the reasons to be aggressive here is that building codes are upstream. You won’t see the impacts on the market (reduced gas consumption, strong demand for induction stoves & electric space heating) until many years after this change, and it’s precisely those shifts in demand we need to drive further advancement in electric stoves and heating to make them even better quickly.
- ikr678 5y agoI work for a utility with ~260km of gas pipe, ranging between 60 year old cast iron to brand new polyethelene pipe, and everything in between. We aim for <2% UAFG (unaccounted for gas) and our regulatory requirement is <2-4% depending on the network classification. This is leakage from between our recieving gas and it being metered to the customer. On the customer side, there's another estimated 2-4% loss. Get your appliances serviced regularly!
