I believe the chart is simply the cost to generate 1 million BTUs per a specific fuel source (Cost in NH per the title) so it is agnostic regarding the space itself & the underlying efficiency to heat or cool it.

The British Thermal Unit, or BTU, is an energy unit. It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. 1 BTU = 1,055 joules, 252 calories, 0.293 watt-hour or the energy released by burning one match. 1 watt is approximately 3.412 BTU per hour

This chart will change drastically based on the price (cost) assumption of the fuel source itself.

Correct. For any given fuel your end cost would be based on the efficiency of the use of it. That is why heat pumps (used in min-splits) cost less to run than electric baseboards while providing the same end effect.

Please don’t do an eye roll here....I have never heard of mini splits. If a homeowner with electric baseboard heat wanted to switch to the newer more efficient mini split system, what is entailed, and would it be terribly expensive to do? We have electric bb, and propane system was added later. I am wondering if it makes sense to do the mini split system since it sounds efficient and reasonable in cost to operate, even with N.H.’s high electric rates. Small cape, about 2200 s.f. Thanks for opinions.

In Canada, by a Canada law, have heard that all propane heaters must be the design that continues to make heat when the electricity is down. Is this really true?

Is not the case in USA or in NH, and you can get either a propane warm air space heater that continues to work when the electricity is down or goes out until the electricity comes back on ...... which can make a big difference if the power is out for 24-hours in very cold temps. The non electricity dependent propane heaters operate on the propane pressure within the propane storage tank, and have a pilot light and a 12-volt dc Piezo (whatever that is?) self-generating hot air heat that can work a remote wall mounted thermostat.

It has a propane pilot light, which is the key design to the non electricity dependent systems.

A Rinnai direct vent will shut off without electricity, and come back on, when the electricity is back.

The use of pilot lights on gas appliances is being replaced by on demand ignition which are fired by A/C but most decent stuff has a battery backup should the lights go out. It's a safety thing.

This all comes down to properly preparing your situation in the event of power loss. Paying a steep premium for propane cause it works without electricity is pretty short sighted.

Installing a transfer switch and purchasing a portable generator is short money and can give you plenty of power for the essentials when needed.
