Minewater 3.0Design on use

Peak load 200 – 400 hours (10–20 days):Feed temperature 38 – 45 ˚CShort term storage (hour/day)

Base load 3600 hours (5 months):Feed temperature 30 – 38 ˚C

Mid/long-term storage (week/month/season)

Hot water demand < 2 hours/day:Heatloss HT-network 8760 hours/year > 35% total heat demand;

LT-network + booster HP < 5%
