Eres 300 Litre Heating Vessel - ER-300LTVESS

The Eres 300 litre Heating Vessel (ER-300LTVESS) offers robust pressure management for large commercial or domestic heating systems. This high-capacity Expansion Vessel handles water expansion, ensuring your network operates safely, efficiently, and lasts longer.

Safeguarding Large Heating Systems

Sealed heating systems see water expand when heated. Unmanaged, this causes dangerous pressure build-up, straining boilers and pipework. The Eres 300 litre Heating Vessel is built for larger systems—offices, schools—providing the 300-litre volume to absorb thermal expansion, acting as essential breathing space.

Eres creates durable components. This Expansion Vessel has a welded structure for pressures up to 5-6 bar, with a red epoxy coating for durability. The ER-300LTVESS resists corrosion and pressure cycles. Its non-replaceable, flange-held diaphragm resists glycol mixtures and has low gas permeability, vital for system integrity. Operating up to 100°C, it supports your Heating Category infrastructure's health. A correctly sized vessel reduces running costs and extends boiler and Grundfos pump life. Using this quality Expansion Vessel, perhaps with parts from our Expansion Vessel Category or Honeywell controls, is key for a resilient setup.

Key benefits for your system:

• Manages High Water Volume: 300-litre capacity ideal for large commercial/domestic systems.
• Ensures System Safety: Prevents over-pressurisation, protecting boilers and pipework.
• Maintains Stable Pressure: Keeps pressure consistent, reducing component wear.
• Durable & Robust: Welded structure, epoxy coating for long service life.
• Improves System Longevity: Mitigates pressure stress, extending system health.
• Reduces Call-Outs: Minimises common pressure-related faults.
