About Stack
Temporary heating when you need it most
A commercial boiler breakdown can disrupt day-to-day operations, particularly in buildings where reliable heating and hot water are essential.
Stack specialises in temporary boiler hire, backed by extensive commercial heating experience. We assess your existing heating system, the capacity required and the practical installation arrangements before recommending suitable equipment — then deliver it on a trailer, ready to connect.
Our aim is simple: to help you maintain essential heating services while your permanent system is being repaired or replaced.
