Chilly :(

Took the dogs out for their bedtime pee and By Heck it was chilly ... went out to greenhouse and shut it up tight. Thermometer is down to just below 8C :(

 

4'c when I got up to go to work @5am - not good !

 

Very autumnal!

 

You need a house with better thermal mass then - your annual heating must cost a fortune if you need heat for one cold night in August?

 

Heat loss is the issue though ... if the building holds the heat, and the insulation keeps it in, then you'll be more comfortable (and then you can set the thermostat to the setting you like). Thermal mass and insulation will keep you cooler during heatwaves too - well, the first few days at least.

 

Even though it was sunny yesterday there was a definate nip in the air.For the first time in ages the plastic greenhouses were zipped up for the night.

 

I know that scenario too. It is OK downstairs all afternoon and then you shut the doors and windows when the sun goes down and get on and make dinner ect. Later, you go to the foot of the stairs and an icy chill reminds you that all the windows are still open up there! And it's a bit too chilly!!

 

Me too!

I'd love to build an extension here - not that we need the space, but so that we can have an exceptionally thermally efficient building. With mechanical heat recovery we should have the best of both worlds - fresh air and low heat loss. We could then hibernate in the extension for Winter, using just the heat from an occasional lighted match!

 

Might be worth investing in that foil-backed insulation that B%Q sell cheaply from time to time, and lagging the roof (i.e. below the tiles), rather than the joists. I gather that can make a significant difference, more so in a bungalow.
