Packaged Buffer Vessels
Stokvis Econostor®
EconoStor® is a compact, pre-assembled system that delivers semi-instantaneous domestic hot water to larger buildings, with outputs up to 230 kW. It combines a plate heat exchanger, charging kit and stainless steel storage tank in one package. That reduces design time, site assembly and the number of components to coordinate.
EconoStor® can be connected to a district heating network or a local heat source. It is designed to run efficiently on low- to mid-capacity heat sources.
Key features
- Pre-assembled charging kit, ready to mount on the storage tank
- Stainless steel storage tank, 300–1,500 litres
- Choice of plate heat exchanger: copper-brazed, or fully stainless steel fusion-bonded (AlfaNova)
- Charging kit available with or without a 2-port or 3-port control valve
- Optional electronic or self-actuated control
- Simple, robust design for straightforward installation and maintenance
Buffer Vessels
Stokvis Econotherm®
Stovis Econotherm® buffer vessels are a key part of efficient plant room design, helping to improve system stability, performance and longevity. Acting as a thermal store, they add system volume and regulate temperature changes, ensuring a more consistent and reliable operation across heating and cooling applications.
Available in both mild and stainless steel, these vessels provide a flexible solution for a wide range of systems, from heat pumps and boilers through to chilled water applications.
Key features:
- Supports system efficiency by storing and releasing thermal energy as demand changes
- Highly efficient injection foam insulation
- Easy lifting and positioning features
- Available in mild or stainless steel options to suit application requirements
- Fully insulated design helps minimise heat loss and improve overall efficiency
- 2,500L to 5,000L+ sizes available
