You'll find water heaters for residential and commercial properties with various flow rates and capacities. Water heaters come vented or unvented, so make sure you know the difference before ordering: 

This is a standalone system that's a great solution when there's no boiler access. It's typically placed in a loft and relies on gravity to supply a property.

The main advantage of this system is that you still have access to limited hot water should the mains supply be cut off.

These connect to the mains water supply and don't require a cold water tank. It'll need to be installed alongside a system boiler to heat the water.

This improves the performance of your bath and shower, supplying them with reliable pressure. Plus, the absence of a separate tank helps avoid issues such as freezing during winter or contamination.

Whichever you choose can be powered by gas or electricity. Gas systems are simpler to maintain and can heat a home quicker, while electric heaters are quieter and typically more efficient.
