Our current Baxi range includes both direct and indirect unvented cylinders, designed to suit different installation requirements.
Direct Unvented Cylinders
Direct cylinders use immersion heaters to heat water, making them ideal for properties without a boiler or where electric-only systems are required.
Typical applications include:
- Flats and apartments
- Small commercial properties
- Office kitchens and washrooms
Indirect Unvented Cylinders
Indirect cylinders are designed to work with external heat sources such as gas or oil boilers. They offer faster recovery times and are commonly used in larger or higher-demand environments.
Typical applications include:
- Residential homes with boiler systems
- Hospitality environments
- Commercial buildings

Maintenance & Spare Parts Support

Choosing the Right Hot Water System
Selecting between direct and indirect cylinders depends on your installation:

- Existing boiler system? → Indirect cylinder
- Space or demand considerations? → Capacity selection becomes key
