Reliable Pressure Vessels & Pressure Tank Vessels for Heating Systems.
Pressure vessels (also commonly called expansion vessels or expansion tanks) are essential for any sealed heating system. They proactively absorb excess pressure caused by water expansion as it heats, safeguarding your pipes, pumps, valves, and other vital components from damaging strain.
As water temperature rises, it efficiently absorbs the excess volume; when it cools, it seamlessly releases the stored water back into the system. This continuous, intelligent buffering eliminates pressure spikes and drops, ensuring smoother and more reliable operation, and significantly extends the lifespan of your valuable equipment.
Selecting & Maintaining Your Pressure Vessel:
Choose based on system requirements.
Optimise your system's performance by precisely matching the vessel’s capacity, pressure rating, and connection size to its specific demands. Avoid inefficiencies and improper buffering that result from oversizing or undersizing.
Check pre-charge pressure.
Most vessels arrive pre-charged with air (typically around 1 bar) – a crucial factor in maintaining the correct balance. Regular checks and adjustments are essential over time.
Inspect regularly.
Don't wait for a problem. Over years of service, membranes can degrade, air charges can leak, or corrosion can set in. Make proactive testing, maintenance and servicing of your vessel a standard part of your regular heating system checks.
Replace when necessary.
If you observe frequent pressure drops, a loss of charge, or uneven heating, these are clear indicators that your vessel may be failing and requires immediate replacement to protect your system.
