Unvented hot water cylinders

In an unvented system there is no cold water tank – instead the sealed hot water cylinder is fed directly by the cold water mains. Since they are operating at mains pressure, they offer much better flow rates, meaning your shower and bath performance should be higher.

The other major benefit is that you don’t need to maintain a cold water tank in the loft (which vented systems require). This is good news since not only does it free up space, it also removes the potential freezing issue during our long cold winter periods.

In addition, since you aren’t relying on gravity to move the hot water around the home, the unvented cylinder can be located pretty much anywhere in your property.

Other advantages of installing an unvented system include reduced noise in the system since there is no cold water filling of the water storage cistern, and since there is no water storage cistern and the system is essentially sealed, the cold water is not at risk from contamination.

Power flushing

Over a period of time, deposits of sludge, rust and debris naturally build up in your central heating system due to the constant flow of water, causing it to degrade. 

Power flushing removes these deposits through the use of a purpose-built high pressure flushing machine and cleansing solutions.  As the cleaning process takes place inside your system there is no mess or fuss to worry about and it can take less than a day to complete. 

Also, when the power flush is complete we always add a special inhibitor solution to your system as standard.  This inhibitor is vital to help prevent further build ups of debris and means that  you can relax knowing your system is protected. It is advisable to have your central heating system power flushed every 5-10 years, depending on the age of the system and also whether it is has been serviced regularly.
