About Tank & Tankless
Tank & Tankless is a US reference that compares home water heaters spec by spec, using federal data and maker manuals rather than sales copy.
What this site covers
Tank & Tankless explains the main types of home water heaters: gas and electric tanks, gas and electric tankless units, heat pump models, solar systems, point-of-use heaters, and combi and indirect setups. The guides compare them on the numbers printed on spec sheets and labels: uniform energy factor (UEF), first-hour rating, flow at a given temperature rise, expected life and what each needs for installation.
Beyond the comparisons, the site covers sizing, energy costs, federal efficiency rules, installation basics, routine care such as flushing and anode checks, and the common faults behind no hot water, leaks, noises and odors. Figures come from sources such as DOE, ENERGY STAR, the Federal Register and maker manuals. The method is set out on how these pages are made.
What it does not do
This site does not sell, install, service or repair water heaters. It is not a contractor and has no technicians, service area or showroom. It is not affiliated with any water heater maker, and no maker has paid for a mention or a ranking. In fact, the site does not rank brands at all.
When a job involves gas lines, venting, 240 V wiring or a permit, the pages say so and point you to a licensed plumber, electrician or gas fitter. The guides help you understand the work and ask better questions. They are not a substitute for someone qualified looking at your heater.
Who owns it
Tank & Tankless has the same owners as SoftPro Water Systems and Quality Water Treatment, two stores that sell water treatment equipment such as softeners and filters. Links to the stores appear only on the few pages about hard water, scale and well-water odor, with a note beside each one. The details are on ownership and store links.
How pages are kept current
Every page carries a revised date. Prices, rebates, tax credits and federal rules change, so pages are checked against their sources and re-dated when something changes, for example when DOE amends a standard or the IRS changes a credit. Errors found in a later check are corrected, and the revised date changes with them.
Each guide ends with a short note on what it is based on and what was left out. Pages carry the byline of the Tank & Tankless desk.
