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
Grant Wave Cylinders
Wave cylinders and thermal stores have been developed to the highest specification, as you would expect from any Grant product. The cylinders have powerful mains-pressure performance with exceptionally high hot water flow rates, while the thermal stores have been specifically designed to enable complementary technologies to be easily combined.
The Wave range of cylinders and stores have sizes ranging between 125 and 500 litres, and are designed to be coupled with almost any household hot water system from oil and gas boilers to electric heating, air source heat pumps and even solar thermal.
