Heating Expansion Vessels

Heating Expansion Vessels have been designed to protect closed central heating systems from becoming overloaded by excessive pressure. 

In most cases, they're relatively small, You may even have one in your home or office already! They're designed to give space to the additional pressure added to the system when hot water expands. 

Not having an expansion vessel in a closed heating system can decrease the lifespan of your heating system, cause your heating system to run inefficiently and cause leaks to occur. Adding a small yet effective expansion vessel can remedy this. 

At Pump Sales Direct, we stock all the bigest brands of expansion vessels including brands such as, Grundfos, Zilmet, Heatwave, Reflex, Flexcon, Aircon and Stuart Turner.
