ᐅ External perimeter insulation of the foundation slab, risk of mold in the basement

Hi,
for our house with a basement, both builders have only included insulation on the concrete slab. An additional cost for external insulation is about 3400€ (WLG035, 10cm (4 inches)).
The basement will mostly be used for storage, while the hallway and a large room will be heated with underfloor heating. Would you recommend adding this insulation to avoid or minimize cold bridges in the corners and thereby reduce the risk of mold?
Regards,
danielh

But electric, not thermal...
You’re basically ignoring the seasonal performance factor.
19 cents is correct if you’re heating purely electrically with a heating mat.

karliseppel25 Oct 2012 15:55Well – I’m genuinely interested in what building services engineering has to do with the transmission heat loss of the building envelope in terms of costs, even if it’s off-topic 😀

Please read the above again! Demand is not consumption (kWh). Otherwise, heat pumps would be a very poor investment. karliseppel schrieb:

karliseppel26 Oct 2012 13:44Hmm, but you have mixed up consumption and demand. Ultimately, it is only about the consumption of thermal kWh. The fact that these kWh are not directly visible on your electricity/gas/district heating bill because the seasonal performance factor/efficiency/line losses influence it depending on the system must be taken into account. However, you gave the impression that a heat pump would result in energy costs that are four times higher, which is balanced out by the “pump output,” making the systems relatively similar in terms of the cost of thermal kWh.
