About HeatPick
An independent, spec-based guide to heat pump and gas tankless water heaters.
HeatPick is published by Informative Buy, a small independent business run by Gerardo Galicia in Venice, California. We built it because water heaters are still sold on brochure first-hour claims, “energy factor” figures that predate the current test, or tank sizes that are not the certified storage volume, while the legally certified numbers — uniform energy factor, first-hour rating, and tankless gallons per minute — sit on ENERGY STAR records. Here, every product is compared on those official certified ratings, scored with a formula printed on the page, and linked back to its sources.
Today the site covers 3 categories, 119 products and 32 head-to-head comparisons, from 240-volt integrated heat pump water heaters to 120-volt retrofit heat pump models and condensing gas tankless water heaters.
How we research
- Manufacturer data first. Specs come from official product pages, spec sheets and manuals. Each product lists the exact pages we used.
- No guessing. If a figure isn't published, we show "Not listed" and score it at the lowest published value in the category, never as average.
- A transparent formula. Weights and scales are on every comparison and on our How we rank page.
- Honest about limits. Our comparisons are research-based. We don't claim hands-on lab testing, and we don't publish made-up reviews, ratings or prices.
How we make money
HeatPick participates in the Amazon Services LLC Associates Program. When you buy through a "Check price" button, Amazon may pay us a commission at no extra cost to you. Commissions never change the order of a ranking, and no brand can pay for placement. Details are in our affiliate disclosure.
