How h2x Eliminates The Spreadsheet Burden
A wall shift, added bathroom, or layout tweak can invalidate an entire spreadsheet pack. Learn how h2x design software removes the manual recalculation cycle, keeps data consistent, and speeds up revisions without guesswork.
Read MoreWhy h2x Is the Natural Successor to Hevacomp — And Why Engineers Should Make the Switch Now
What is more dangerous to an engineering firm: a software that doesn’t work, or a tool that still does? On January 1, 2026, Hevacomp became a ‘ghost platform’: functional but dangerously outdated. Sticking with this legacy system isn’t playing it safe; it’s gambling your compliance, accuracy, and reputation.
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.
