A web-based toolkit for HVAC and plumbing design based on Swedish engineering practice. Calculate probable flow rates, pipe sizing, duct airflow, expansion vessels, Kv values, SFP, DHW circulation and cooling loads — all in one place.
I built VVS Dimensionering because VVS design calculations are often scattered across spreadsheets, PDFs, software and manual calculations.
I wanted to bring the most common calculations into one simple web-based tool that is easy to access and built around Swedish engineering practice.
The goal is simple: spend less time setting up calculations and more time actually designing.
VVS Dimensionering currently includes tools for probable flow rates, pipe sizing, airflow, expansion vessels, Kv values, SFP, DHW circulation and cooling loads.
I’d love to hear from other engineers and designers: which calculation would you want to see added next?
