Our range includes several types of water heaters to suit different installations:
Point-of-Use Water Heaters
Designed to deliver hot water directly at the outlet, these compact units are ideal for:
- Hand-wash basins
- Office kitchens
- Small commercial spaces
Point-of-use heaters reduce pipe runs and minimise heat loss, making them an efficient choice for localised demand.
Undersink Water Heaters
Installed discreetly beneath sinks, these units provide stored hot water for single or multiple outlets.
Common applications include:
- Kitchens and staff areas
- Washrooms
- Utility rooms
Oversink Water Heaters
Mounted above the sink, oversink heaters are typically used where undersink space is limited.
They are commonly found in:
- Workshops
- Garages
- Commercial wash areas
Hot Water Storage Systems
For higher demand environments, storage water heaters provide a larger volume of hot water and consistent supply across multiple outlets.
Used in:
- Hospitality environments
- Commercial buildings
- High-demand residential settings
