Grant DuoWave Cylinders

The DuoWave range of mains pressure hot water cylinders were developed to meet the growing demand for systems that combine a renewable heat source with a standard oil, gas or electric boiler.

They are particularly suitable for use with solar hot water systems like Grant Solar Thermal. When correctly installed, this arrangement can significantly reduce the dependence on traditional fossil fuels resulting in lower energy bills.

Sizes range from 170 litres to 500 litres, comprising five direct and six indirect models which can meet the needs of even the largest of domestic properties.

Features & benefits

  • *25 year material guarantee on cylinder/store shell (Subject to Terms & Conditions)
  • Featuring high efficiency corrugated heating coils, the Grant DuoWave range is developed to ensure a maximum transfer of the energy collected by renewable systems
  • As a safety feature, indirect cylinders come with a control/high limit thermal cut-out that operates at 90°C.
  • No anode required
  • Immersion heater
  • Labelled and colour-coded tappings to make installation easier.
  • Global warming potential (GWP) = less than 3
  • Ozone depletion potential (ODP) = 0
