As with many industries, energy efficiency is fast becoming the driving force in initial pump selection. The H & V building services market is no exception with variable speed drive pumps offering units that perform not only to the precise needs of the system but also offer massive savings in running costs.
It should be noted that many existing installations can be upgraded retrospectively on both circulation and water booster sets and advice is freely available.

Until recently, pumps were produced in a multitude of dimensional standards making major pipework modifications necessary when replacing these obsolete units. AJH have a wealth of knowledge of these earlier pumps allowing us to select new models which will require little or no change to the pipework.
