What is a Pump and why do I need one?

This is a fair question – and Mr Central Heating has the range of products to help you make this important selection. Some of our favorite pumps are manufactured by Grundfos. They offer a full line of shower pumps, central heating circulating pumps, macerators, condensate removal pumps, and pumps to boost the water pressure of an entire house. Clearly, you need a good pump.
