The 200% seasonal efficiency is a bit off, Nordic models, measured with the “colder” European climate zone, get 300%+ and have guaranteed output at -25C / -13F. Example model from Mitsubishi:
It’s worse than 5.5x or 4.3x in warmer areas but the right model air source heat pumps work fine down to pretty damned cold. Norway and Sweden have a ton of them as they spend a ton of energy on heating and this saves homeowners a ton of money every year.
Best models optimized for average climate now reach 5.5x or better in the green, moderate zone, SCOP of 4.3 is actually pretty terrible but this one is built to be ice proof.
Example latest bestest heat pump with 6+ seasonal COP:
A double espresso from 16g of beans is less than 40ml and stronger than a bigger lungo from a nespresso pod (~7g coffee).
Smaller cups tend to be stronger. That same double espresso with 130g ice and 100ml milk and blend until ice is crushed makes a pretty strong frappuccino.
From espresso to lungo / americano to Starbucks recreations, they all basically use the same dose but wildly varying cup size.
Cup to mug of the same strength filter coffee makes a difference though.
