Why does 0°C winter sunshine feel warmer than 10°C indoors?

Perhaps we have misunderstood warmth for years

0°C Outside · Sun

You open your jacket.Sunlight touches your face.

It feels warm.

Aha Moment

10°C Indoors · No Sunlight

You step into the room, It should be warmer.

Yet, it feels colder.

Why ?

Our built-in understanding of warmth is:

Warmth = Air Temperaturer

Perhaps because we've misunderstood warmth.

——————

So for decades we've been spending our energy on:

Heating the air.

Focus on:

Room temperature, air circulation, heating the entire room.

Hope that the air can warm the people.

But warm air was never the real goal. It was the person.

Comfort begins when warmth reaches the body — not merely the air around it.

Reimagining warmth, like sunlight in winter.

In times of exploding energy costs, Sonneins was developed to rethink heat — more personal, more efficient and exactly where it is needed.

Zone Comfort

Heat only where you need.

Efficient

Less energy, more comfort.

Natural

Pleasant warmth like from the sun.

Just like sunlight on a cold day — you feel the warmth directly, without the air needing to be warm.

Designed for the spaces, you actually use.

Stay focused without overheating the entire house.

Big comfort for compact living.

Airbnb Cabin

Direct warmth for detached spaces.

Warm mornings without waiting for the room to heat up.

Camper/Vanlife

Modern life happens in smaller, more personal spaces.
