Each boiler is delivered with a wood lagging kit as shown plus fitting instructions
All "Miniature Steam” boilers are hand crafted from copper and copper alloys silver soldered together. Each boiler is hydraulically tested to more than twice its working pressure and comes complete with a test certificate. They have unique mounting systems that enables them to be mounted in any convenient location within the boat hull. The pressure gauge shown is standard for this boiler
Design & Construction Standards:
“Miniature Steam”, boilers are built to the highest quality standards.
They comply. where appropriate, with the following design, construction and testing requirements of:
- Australian Standard AS 4343 Level E
- Australian Miniature Boiler Safety Committee, (AMBSC) code part 3 Issue 1.0 - 2006 Sub-Miniature Boilers and AMBSC code part I . Issue 7 - 2001
- UK Boiler Test Code 2018 – Volume 2
Every aspect of the boilers has been carefully designed and rigorously tested to meet the highest possible steam generation performance. Each has been designed and manufactured by “Miniature Steam”, including the cast ceramic burner insert.
