[Boilers, furnaces and stoves](https://www.materialinsights.org/energy/e_combustion_heat/) (energy) and [Recuperators and regenerators](https://www.materialinsights.org/energy/e_recuperators/) (energy): 3 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · Direct · Boilers, furnaces and stoves → Recuperators and regenerators*

Recuperative burners recover heat from furnace exhaust.

### 2. Energy flow

*Physical flow · 99% of flow · Recuperators and regenerators → Boilers, furnaces and stoves*

Recovered heat warms combustion air before burning.

- **99%** of Recuperators and regenerators's energy goes this way

### 3. Price link: host equipment

*Cost and price · Strong · Both ways*

Recuperators are fitted to furnaces, kilns and burners, so they sell with new combustion equipment. Yearly moves correlate at 0.78, a common driver from US manufacturing costs and industrial investment.

- **0.16** monthly change correlation
- **0.78** 12-month change correlation
- **0.92** fitted elasticity
