About us

Welcome to Surejust Manufacturing

Surejust have been manufacturing equipment used by the marine industry for over 25 years, our reputation for quality is shown throughout our product range.

Our calorifiers are the best of class in the industry, designed and hand built in our purpose build factory; every calorifier follows stringent quality tests and extreme pressure testing to ensure it quality and reliability every time.

The Sure Cal boiler or calorifier has been our flagship product for decades, high quality materials, superb hand built construction and a hard earned reputation for quality make the Sure Cal calorifier one of our top selling products year on year.

The Sure Cal calorifier is an industry leader and the favoured choice for the boat builder or individual who demands reliability quality and performance for their onboard water system.

A Range of options are available for the surecal to make installation as easy as possible, these can be found at the bottom of the surecal page.

The Sure Cal 'Super Yacht' range was introduced a few years ago specifically for the high demand super yachts increasingly being produced across the world. The theory was to take our flagship Sure Cal calorifier and perfect it for the Super Yachts it would serve. The result is the high end quality and performance of the Sure Cal calorifier on a much larger scale!

You now have the ability to buy our products online and view all our product information sheets and ranges directly from this site.
