Breezy outside. 22.5c Indoors. The thermostat is on low.

It depend on a property as my last house get immediate moulds on joints in kitchen sink and bathroom but this house nothing at all or trace of it as all still look new. It dries quickly and after shower I wipe dry asap and leave window open for a while.  Recent cold night had created lot of condensation on windows which I dry up quickly after open shutters.

This morning I experimented turning the heat on while sunny with thermostat set at 21.  Took less than an hour from 19C to 21.5 when it cut off and continue to rise to 22.5 from the sun.  It used a bit less gas than evening heat up for nearly 2 hours as i did on Thursday which was from 16 to 20C as I was away for work.  Really comfortable warmth today then drop to 20C when I close shutters.  Will see how much by morning if hold enough.  

As normal it's 16.5C downstairs and 18.8C upstairs. 11C outside.

The heating kicked in for an hour or so earlier this morning.

A drier and warmer environment after that 21c boost of temperature between 6pm Friday evening and 6am Saturday morning.

Relative humidity is back down in the high 60's low 70's (rather than the 75-85% on Friday afternoon ! )

Temperatures at the moment

Hallway 19.8c

Dining room 19.8c

Lounge 21.0c (some morning sunshine through the east facing windows)

Bedroom 20.2c

Normal 22.5c. Sunshine through the window of the room with the wall thermostat control.

Full sun today resulted 20 to 21C so comfortable and no heating.

15.1c Outside so not cold indoors 21.5c. No heating on.

16.5 downstairs, 16.3 outside, 19 upstairs.

No heating overnight, but as close as it could be without it coming on.

(The indoor temperature actually fell during the day yesterday, down to 16C by mid-afternoon, before warming up by half a degree again overnight.)

An incredibly mild night here with outside temperatures varying between 17c and 18c !

As a result minimal heat loss has occurred since last night.

This morning we have the following.

Hallway 20.0c

Dining room 20.0c

Lounge 20.7c

Bedroom 21.3c

The RH has crept up again though.

23.0c in the afternoon sunshine.

17.5C outside, 17C downstairs and 21C upstairs.

It'll be a long time, many months, before it hits 20C downstairs again.

57% humidity upstairs here (=dp of 12.5C), downstairs it's 75% (=dp of 12.5C).

Outside the dewpoint's 12.7C.

None of that should be a problem, though, as it's not going to be colder than 12.5C indoors any time soon.

Patio doors open most of the day downstairs and 23C in my office upstairs.  Autumn. What autumn?

Same thing again and we went out all day in the town and it was really warm and sunny for mid October a 17C no jackets needed, around 21C to 22C and bedroom 1 just tad below 20C because no more sun until next year March.  Bedroom 2 was 23C and yesterday was 23.5C.

Now 20C and very comfortable without any chill feeling and no jumper needed.

Warm out (high 19.1c), warm in. 

Hallway 20.5c

Dining room 20.7c / 73%

Lounge 21.1c / 72%

Bedroom 21.0c / 82%

Wearing T shirt and shorts again indoors. Very very pleased. 

If someone had said to me when we arrived back from that weekend away in mid September when the house was just 17.3c that a month later I would have used the central heating for just a few hours to dry the house a little I wouldn't have believed them.

Normal temperature. 22.5c.

Logging in while I'm at lunch - it's now 16C indoors, downstairs. If I were to magically go home right now the heating would come on! 

At the moment, we are using about £1.50 gas a day, a couple of showers/bath/washing up and a blast of heating first thing to get the temp from 15/16c to 18c. Fairly happy with that for now.

The downstairs temperature clicked down to 15 and that's triggered the heating to come on - the thermostat is set to 16.5, so it'll be on for a while. 20C upstairs, but the heat won't do much up there.

22.0c Indoors at the moment. The thermostat turned down a degree.

20.1c to 21.4c were the early evening peaks yesterday.

A general 19.0c to 19.9c downstairs this morning. 20.7c in the bedroom.

No heating, RH's in the low 70's, no dramas, all good.

To stop mould. My house tends to develop mould in areas such as behind cupboards if the temperature falls too low.
