In Madrid city
we are not used to houses but to apartments, but the insulation normally is better than in Dublin (or what I have seen so far in the last 6 years).
There are old block of apartments with central system, meaning that there is a central boiler for the whole block (apparently is more efficient like that).
The new apartments or the houses have their own boilers.
Normally they are all connected to pipes in the street that supply gas for the boiler, but some houses might have their own deposit where they store liqud gas for their own bolier.
Last, but not least, the heating system is way different to Ireland. When you have your own boiler, you will have a thermostat where you control the temperature that you want to be in your home (let's say 21 degrees) and set a time frame. The boiler will automatically stop when the place reaches those 21 degrees, rather than (what I have seen in all the places I have been here) staying all the time on for a period of time.
Another thing different is that we instantly have hot water all the time, we don't need an innersion or something similar.
TLDR: radiators, boilers, etc. Heating with AC is way more expensive.
