Is room taking too long to warm up?

Sorry forgot to say our highs and lows here where about the same. Low of 3 and high of 7

Certainly food for thought here!!

Thanks for the challenge!

I am going to continue monitoring for the next couple of weeks but won't post any photos I'll just record figures and lost a summary!

Part of the reason I haven't done anything yet is I have a 7 zone controller with OpenTherm.

If I do the experiment as is, the results might be skewed.

However, I will take a gas reading at 8:30. Run the house 24 hours. Then go to twice a day for tomorrow.


However, 24 hours is also a statistically insignificant.

OK - readings are....

Secondary meter - 271.241

Boiler software -
Heating - 634.9477
Water - 145.5553

All zones except the utility room are to be 21.5 for 24 hours.

House make up is a mid 80#s detached 4 bed. Cavity walls insulated, poorly.

3 People (one 7 year old).

Ground floor is all UFH (70/80 metres)
Upstairs are rads sized to run at 55 degrees from the boiler at -3 or so outside.

Tomorrow I will set a 4 hours in the morning, 4 hours in the evening cycle and see what the difference is.

dan you need to let your house cool down before you do the timed experiment, turn heating off for a week

You have yet to meet my missus I take it?

Before we had kids our heating was set for a few hours in the morning then off till early evening. Then when we had our first and my wife was home all day the heating was on all day from around half 6 till 10 PM - I fully expected the heating bill to skyrocket, but it didn't - it did increase but 'only' by about 20% or so vs the previous year.

@Dan Robinson How did it go mate? Interested to see another set of figures.

I put my Nest back into the system for yesterday and it used roughly 1.5m3 more with it on but I forgot that it was a Saturday and it stays on longer than as we are all in the house so not really a fair test. I'll do another in the week when the kids are at school and it's the same situation as the first two tests.

Pinching a loaf at the moment. Took the readings though. Will post up after, but won't have time to break them down... I'm sure one of you guys can manage that. However phase 2 will have to wait until tomorrow.

Otherwise the house week be carrying heat from the last 24 hours.

Haha, I was doing the same hence my post. It's the only time I get a bit of peace on a weekend!

What I'm also doing is logging the data. Can post the log files up too.

Which, in view of where I'm sitting at the moment is probably a poor choice of words

 

[Dan Robinson]

Gas meter - 280.384 - 271.241 = 9.143
Ch meter - 645.2662 - 634.9477 = 10.3185

Hw meter - 146.8456 -145.5553 = 1.2903

I also should mention there was no noticeable improvement in comfort, but I suppose that is very subjective.
