Pool Heater Sizing and Heat Up Time

Enter the volume and the temperature rise you want and see an output range and an estimated heat up time.

These tools give planning-level estimates from typical values. They are not quotes, designs or engineering, and results depend on your actual site, soil, depth, access, local rules and conditions. Only a site visit can confirm what a project needs, and we give you a written scope and price before any work begins.

Questions

About this tool.

Is this a heater quote?

No. It is a planning estimate. A designer confirms the heater with local conditions and use.

Heat pump or gas?

Heat pumps are efficient for steady use, and gas heaters are fast. Hybrid setups combine them.

Does a cover help?

Yes. Most heat is lost at the surface.
