To understand the difference in a short and simplyfied way:
1. Your examples are heating up the inside air by using energy (burning fuel). Doing so will always be less than 100% efficient, some heating technologies are as little as 10-20% efficient (energy per kWh)
2. Heatpumps are instead using energy to do heat transfer. Moving heat from the outside to the inside.
The latter is way more efficient, with easily 300-400% efficiency. But obviously the colder it gets outside, the less heat is in the air to extract and the efficiency goes down.
Love the concept but hate the smell of these "air fresheners" that just spray horrible perfume.
Thank God for products such as carbonfilters and Yocoair that remove odour instead.
Is this article old? Haven't heard anyone say or believe that .org is anything special in 10years.
Who is saying this? Same books that claims smoking is good?
It has been motivated at least in Denmark (limit was 1000, now 100) and Sweden (limit 500) that larger events attract people traveling to it. This traveling and being among large crowds large is what they want to avoid.
While smaller events, say a local low division football team, doesn't normally attract a tone else than locals. The exact number is arbitrary but has to be something, right now 100 in Denmark, 500 in Sweden and will likely change over time.
+1 Lastpass created more chaos than solving issues in our company. Multiple dashboards that interfere with each other, horrible overview causing outdated/wrong rights, users having to restart several times before new passwords showing up, bad mobile support and much more.
