The fabric of the house cools off-that may cause it. I know what you mean though.

A lot of it may be down to the sun. When you are in the sunlight it feels a lot hotter than what it is. For example, how often have you been abroad and say one evening its pitch black and 25 degrees but perfectly pleasant to walk around in shorts and t-shirt. The next day you are out in the sun with just your speedo's on and its still 25 degrees but when the sun is shining on you its hot as fvck and you are sweating your **** off.

In short the sun radiation can make it feel a lot hotter than what the ambient air temperature is.

It's because the Earths axis is tilted.

I reckon it's because your core body temp. is usually a bit higher in the summer. The same air temp in the winter makes you feel a bit chillier.

Disagree with your reasoning. Temperatures quoted will be in the shade, so the direct sunlight temp will be a lot higher.

And speedos?

my temperatures are room stat temps and are in the shade, both at 20 degrees.

Just do what I do, have the heating on full blast and light the woodburner

That's my little contribution towards global warming

It is all about the tilt of the Earth's axis. Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January! The Earth's movement around the sun causes the seasons, but it does not affect the temperatures during the seasons.

During the summer, the sun's rays hit the Earth at a steep angle. The light does not spread out as much, thus increasing the amount of energy hitting any given spot. Also, the long daylight hours allow the Earth plenty of time to reach warm temperatures.

During the winter, the sun's rays hit the Earth at a shallow angle. These rays are more spread out, which minimizes the amount of energy that hits any given spot. Also, the long nights and short days prevent the Earth from warming up. Thus, we have winter!

all quite borrowed from here http://www.loc.gov/rr/scitech/mysteries/seasons.html

ok Ipski, tell me this.

A thermometer taking a measurement in winter states it is 20 degrees. the same thermometer takes the temp in summer and it says 20 degrees. However it feels colder in the winter why?

You posted a great piece on why it's colder in winter but that is not the point!

If it's 23 degs outside in July and you set your stat to 20 it's still going to be 23 in your house.

Set it to 20 when it's 10 outside though.........

I blame political correctness!


Seriously though, the thermostat is only in one part of the house and for some reason they always seem to be near a radiator? So not to accurate

It might be set to turn off the heating when it reaches 20 but is the heating man enough to raise the temperature to 20degC?

I'd say your Thermometer is really a stick

I'm with Leslie. In the winter the source of heat is small (radiator, fire) and the cooling effect is large (cold wind blowing past the outside of the house), thus there is a big gradient across a room so you feel chilled as you move around. In summer the whole shell of the house acts as the heating element so the room temperatures are more even.

What I want to know is why my house is set at 18°C but I need the car at 23°C to give the same level of comfort
