Out with the old . . .
Refurbishing or upgrading existing heating plant provides the opportunity to deliver very significant increases in efficiency but there are a number of factors that need to be taken into account. Kevin Stones takes a look at the key considerations.
Multi-service chilled beams enhance refurbishment opportunities
Multi-service chilled beams remove the need for suspended ceilings, resulting in greater room height and more usable space. But their benefits in refurbishment projects don’t stop there, as Terry Farthing explains.

Getting the best from replacement boilers
