[Boilers, furnaces and stoves](https://www.materialinsights.org/energy/e_combustion_heat/) (energy) and [Heat pumps, air conditioning and refrigeration](https://www.materialinsights.org/energy/e_heat_pumps/) (energy): 1 relationship.

## How they are linked

### 1. Price link: competing heating

*Cost and price · Strong · Both ways*

Heat pumps compete with gas and oil boilers and furnaces for heating. The two equipment indices correlate at 0.40 monthly and 0.91 yearly, but this is a common driver: both follow US manufacturing costs and building demand, not a substitution effect.

- **0.40** monthly change correlation
- **0.91** 12-month change correlation
- **1.00** fitted elasticity
