Description

The JPSL buffer tank features a high-performance stratification charging system and is suitable for all hot water central heating systems, whether they use solid-fuel or oil-fired boilers, heat pumps, solar systems, or gas or electric instantaneous water heaters.
Equipped with a sensor terminal strip for variable positioning of the sensors.

Custom designs in other sizes available upon request.

Features

  • Insulation options (to be ordered separately): We recommend this type of tank only with certain reservations when used in conjunction with a heat pump! This is because the “low” flow temperature of the heat pump (usually 50–55°C) can lead to limitations in hot water comfort. We recommend our EHSWP tank, which was developed specifically for heat pumps!
  • Includes a baffle plate, diffusers, and mitered pipes for optimal stratification
  • Highest build quality
  • High-quality S235JR steel in accordance with EN 10025
  • Operating pressure: 3 bar
  • Test pressure: 4.5 bar
  • Maximum operating temperature: 95°C
  • Option to install a contact sensor
  • 5-year warranty
