Does Amply only work for heat pumps?

No — Manual J is about the building, so Amply works for any home and any system

Written by Matt Lowes

No. Manual J is about the building, meaning its heat losses and gains, not the equipment. You can run an Amply load calc on any home and use it to size any system: heat pump, furnace, boiler, straight AC, or a mix.

We love heat pumps and are building more heat-pump-specific features. Amply's core load calculation already works for any home and any system.
