How Do Hot Water Systems Actually Work?
Hot water systems are designed to heat and deliver water for your everyday needs, showers, washing, dishes.
Though different models use different methods, they all aim to deliver reliable hot water.
Here’s a simple breakdown:
- Storage (tank) systems: water is heated and held in an insulated tank, ready for use.
- Continuous flow (instantaneous) systems: water is heated as it flows, with no stored tank and in theory unlimited hot supply.
- Energy sources include electricity, natural gas, solar heating, and heat pumps.
Each type has advantages depending on your home’s layout, fuel connections, and usage habits.
