METHOD AND ADDITIVE FOR IMPROVING THE EFFICIENCY OF A CENTRAL HEATING SYSTEM

摘要

The invention relates to a method of improving the efficiency of a central heating system. The method comprises providing an additive comprising alkyl polyglycosides in order to reduce the surface tension of central heating fluid in the central heating system to thereby improve the nucleate boiling and heat transfer characteristics of the central heating fluid. The invention also relates to an additive for improving the efficiency of a central heating system, a method of introducing an additive into central heating fluid of a central heating system and a syringe adapted to introduce an additive into the bleed valve of a radiator in a central heating system.
