Read MoreBS EN 12831-1:2017: Why Diversity is the Secret to Accurate Heat Loss
For decades, engineers have relied on the simple summation of room heat losses to size systems. However, BS EN 12831-1:2017 turns this linear logic on its head by introducing the concept of diversity. Moving beyond simple summation is now essential, as over-sizing introduces a serious risk of inefficiency that compromises modern heat pump performance.
