## How they are linked

### 1. Energy flow

*Physical flow · Direct · Energy in buildings → Boiler heat recovery*

Condensing boilers capture heat from flue gases.

### 2. Energy flow

*Physical flow · Direct · Boiler heat recovery → Energy in buildings*

Condensing boilers deliver more heat to homes per unit of gas.
