“The guys were great, can’t believe the difference it’s made to our heating” Mrs. G, Cannonsbury

By it’s very nature, your central heating system’s efficiency will drop as it gets older. There are calculations that it may drop by as much as 10% within a couple of months. As systems mature the quality of it’s output drops. A very effective way to bring your system back to it’s optimum state is through powerflushing.

Central heating systems that offer a sub standard output can add significant cost to your fuel bills.
