         | or off. Each manufacturer has their own, undocumented protocol

       | The other is that if you have central air then it seems like you
       | should have a heat pump. You're basically just running the heat

         | If you go fossil fuel, you have only 40% efficiency for Fossil

         | ---------
         | 
         | Today, a Heat Pump can be like 200% efficient, so you 100W of

         | 80W of heating from the heat pump.
         | 
         | Alas, a Gas Furnace is like 90% efficient (10% of the heat
         | escapes in the steam / waste products that needs to be pushed
         | out the chimney, but everything else turns into home heating).
         | So your 100W of chemical energy turns into 90W of heating, and
         | you're done. And that's why our infrastructure in the USA is so
         | much around gas heating, because its better. Especially since
         | we are very rich in domestic natural gas production.
         | 
         | Yeah, we're getting to the point where Heat Pumps + Solar
         | Electricity are coming. But... we're not there yet. On today's
         | grid, Natural Gas heating is likely the most efficient option.
         | 
         | EDIT: Got my units wrong. It should be 100J of energy, not 100W

         | Fossil fuel generation accounts for about 60% of US electricity

         | Another 5-10% is lost due to transmission, so say around 40% of

         | to your house as electricity. Combine those and it means that
         | every 1Wh of electrical energy generated takes the equivalent
         | of 1.5Wh worth of natural gas.
         | 
         | That doesn't sound particularly good, since new natural gas
         | furnaces can be around 90% efficient, meaning that same 1.5Wh
         | of natural gas could produce 1.35Wh worth of heating. Except
         | heat pumps have an efficiency of around 2.5-3, meaning for
         | every 1Wh of electrical energy they consume, they produce
         | 2.5-3Wh worth of heat. That means producing 3Wh worth of heat
         | with a heat pump consumes 1.5Wh worth of natural gas in the
         | standard US electrical energy mix. Getting that same 3Wh worth
         | of heat directly from a natural gas furnace would take over
         | twice the amount of natural gas. Even if your electricity
         | generation is 100% natural gas, the heat pump would be very
         | competitive with natural gas.
         | 
         | Now if you live in an area that gets really cold (meaning heat
         | pump efficiency on average is lower) and all your electricity
         | is generated by an old coal power plant (which is less

           | We're not talking about heating a house using coal - which is

           | 
           | Total systems efficiency for a single-cycle gas-fired power
           | plant lies between 32% to 38% for simple cycle gas turbines,
           | most of those in the USA are closer to the first number.
           | Combined cycle gas/steam turbines can run at up to 60% total
           | efficiency which is about as high as it is possible to get
           | using a thermal power generator [1]. The efficiency of gas-
           | fired heaters lies somewhere between 70% and 95% or more, the
           | upper range is common here in Europe. A good indicator for
           | the efficiency is the fact that these appliances often use
           | plastic flue pipes which is made possible by the fact that

           | might be right, but it's not as straightforward as you
           | suggest. You're right that the transmission losses aren't
           | large, but you seem to be missing the much bigger losses
           | involved in generating electricity from coal.
           | 
           | Currently, the average coal fired plant produces electricity
           | at 33% efficiency:
           | https://www.energy.gov/fecm/transformative-power-systems.
           | That's average, so there are probably plants out there
           | producing at 30%. If we assume another 5% loss for
           | transmission, this takes us down to 25% efficiency as
           | delivered to the consumer.
           | 
           | If a heat pump is 3x the efficiency of resistance electric
           | heat, but you are burning 4x the coal to generate the
           | electricity, are you still certain that a 95% natural gas
           | furnace is never the better choice for efficiency? I'm not. I
           | think the heat pump is probably more efficient in many cases,
           | but I wouldn't eliminate the possibility that there are cases
           | where the natural gas wins.
