Poland heating system, when is it cheaper to switch on during the day and night?

Hi folks.

Could you please tell me when is it cheaper to switch on the heating system in Poland ?
I guess from 00 till very early in the morning and 13-15pm...is that right ?
thanks a lot

what kind of? gas? district?

In my home I set semi-district heating as follow:
5oo-7oo --> 22 stC
7oo-16oo --> 18 stC
16oo-1oo --> 22 stC
1oo-5oo --> 18 stC

In my work, we have recommendation to set district heating for people like this:
7oo-23oo --> 21stC
23oo-7oo --> 19stC

electric gas in a flat...
I mean..is there any time you spend less to switch it on ?
for example I have a boiled to warm the water...when should I switch it on in order to pay less ??
thanks again

ENERGA electricity provider call this taryfa nocna (night rate) 13oo - 15oo i 22oo - 6oo but it isn't set on by default. You have to ask them for new special meter installation.

I find the best method is to rent a furnished apartment and then during winter start burning the contents,

or find a part time job leaflet distributor :)

Some of the saving masters I know, achieve amazing results using
combination of gas/coal stove and solar collector (for domestic water heating).

Hard to believe that the Sun can heat the oil up to 90 st C in Olsztyn's latitude.
