Integrated Control Switchover Temperature Calculator
Determine the most cost-effective temperature setting based on current fuel prices.
A switchover temperature is the outdoor temperature at which your heating switches from your heat pump to your boiler or furnace.
Use the calculator below to determine the most optimal, cost-effective switchover temperature for your integrated control based on current fuel prices.
Today’s cold-climate heat pumps can provide efficient heating at outdoor temperatures as low as -15º F and operate at 2–4 times the efficiency of a boiler or furnace. Customers should work with their contractor to determine the outdoor temperature at which the fossil fuel heating system turns on. This setting can be based on what matters most to the customer: maximizing heat pump usage, choosing the most cost‑effective point based on current fuel prices or following another strategy that supports their comfort and efficiency goals.
To be eligible for a partial home heat pump rebate, integrated controls must be set below the maximum switchover temperatures* as outlined below.

*Switchover temperatures are verified during post-installation inspections and based on 2019–2021 average fuel costs. Please note, the maximum switchover temperature for natural gas systems is 30°F and is designed to support decreased greenhouse gas emissions rather than operational savings.
