How cold is your house without the heating on?

[Notcontent]

I am in a small Victorian terrace. Had new windows, new boiler and some insulation put in recently ( limited by nature of property). I am a bit disappointed by results. Downstairs area has an extension and is better insulated (some new walls) so if I heat that area it seems to retain heat for longer. Upstairs is pretty chilly. I put heating on at bedtime yesterday for a couple of hours and it was about 16.5. No heating on since then and it’s 14 degrees upstairs. I am in London by the way and outside it’s 5 degrees.

is that to be expected in an older house?

That seems reasonable, I hope you don’t mind, I have sent you a PM with a couple of questions. 🙂

Didn't have my heating on at all at the weekend as we were away. Came back Sunday night and the house was 6 degrees. I haven't been able to heat it up to much over 12 since then, despite having the heating on a bit. The temperature just will not rise.

The ventilation unit cost about 250 pounds, and I think another 60 pounds for ducting, and 1/2 day of our sparky, so that's 125 pounds installation. It works better in the direction in which it blows. We ducted it to come into the central hall of our lower ground floor. It keeps the rooms opposite the vent nice and fresh, but the air doesn't seem to push backwards, so it's still a bit musty in the rooms behind the vent. Our sparky also added a second motor to give it some oomph. It's very cold air though that come in atm, but if heated to 16 degrees, the air feels very warm, but the moment you turn the heating off it's freezing. Instead of getting an inbuilt heating element to the PIV, we placed a small radiator underneath the vent, as the same heat in gas is only 1/3 of electricity cost.

we have an old cornish cottage, no insulation ( its on the way for attic ) and our oil boiler motor has died. moved boys into sitting room as their room went down to 6c the other night . with log burner on all day at most we are hitting between 15-17c in just that room x

It's very cold air though that come in atm

This is what I don’t like about PIV units. Our attic is -7 at the moment. I don’t want air that cold being blown into my house.

When our heating broke in cold weather, the house was about 13 degrees, it felt very cold.

We have the heating on all day as working at home, then turn it down to 18/19 at night so it’s comfortable for us and the doggos.
