It's very low for a daytime temperature. Maybe it makes sense with the gas crunch and energy prices in europe, but the specific thing that bothers me about it is hiding that number below the "advanced" checkbox. I don't think people who are used to paying for winter time heating set their thermostat to 68, so using that number to calculate how much a heat pump costs to run will artificially lower the cost of the heat pump in this calculator.

I also live in CO and have it at 64 at night and 68 during day. Very comfortable.

I'm in Colorado and have the furnace set between 63-65 in the winter by choice, nothing to do with cost

I'll take a look back at the residential energy consumption survey and the exact distributions.

The Manual J (industry standard approach to load sizing) uses 70 dF for heating and 75 dF for cooling as its defaults, so we could definitely update the defaults to those, too.

Wouldn't a higher winter temp create more savings when switching to a heat pump?

I guess I can try their model and find out.

Even in warm sunny California I don’t know a single person who sets their heater above 70°.
