A standard non-condensing boiler is usually older and less efficient.

For your renovation projects in Olten, official building register figures offer vital planning insights. Regarding heritage protection, one building out of 3098 is designated as protected, meaning you must contact the municipality early to secure necessary permits. Concerning building volume, for the 1672 recorded houses, the median volume measured according to the SIA 416 standard is 1063 m3, which is essential for scaling your heating and insulation upgrades. Please be aware that data coverage is partial for both building volume and renovation year, as a significant number of properties do not have these specific details documented.
