A focused online store for tankless water heaters and the parts that keep them running.
Tankless Water Heater Shop sells tankless water heaters, point-of-use and mini-tank heaters, portable and RV units, and maintenance accessories such as flush kits, descaler and recirculation pumps. We keep the range focused on water heating so we can describe every product properly: flow rate, temperature rise, fuel, venting, electrical requirements, dimensions and condition.
Buying a water heater online is confusing. Model numbers look alike, flow ratings are measured at different temperature rises, and installation requirements are buried in manuals. We publish the information installers actually need and write buying guides that explain sizing, costs and maintenance in plain English.
GPM, BTU or kW, venting and power needs listed on every product page.
New, open box and refurbished are labeled on every listing and in search results.
Questions before or after you buy are answered by our team within two business day.
We are a retailer. We do not offer installation, repair or maintenance services, and we do not send technicians. We recommend licensed local professionals for installation and explain what to ask them in our installation guide.
