Brewing thermal demand is typically around 25–40 kWh per hectolitre (mashing, wort boiling, CIP and pasteurisation), plus electricity for cooling and packaging. BreweryAtlas models ~30 kWh_th/hl as a representative figure.
Bare hot surfaces — the wort kettle, whirlpool, mash and lauter tuns, boiler-house pipework and the tunnel pasteuriser — radiate and convect the most. Removable insulation on these recovers the largest share of waste heat.
Inzonex removable modular insulation cuts heat loss from covered equipment by up to 96%, brings surface temperatures to ≤45 °C, and typically pays back in under two years.
BreweryAtlas lists regional and large breweries that run real brewhouses, bottling/canning lines and tunnel pasteurisers. Pub microbreweries and brewpubs are excluded — they rarely run the hot packaging equipment that drives heat loss.
