Partner with WaterHeaterCalc
We cover water heater sizing and selection, efficiency and running cost, maintenance, and the accessory layer around an installation: expansion tanks, pans, T&P valves, anode rods, recirculation, descaling and venting.
What we will not do is claim to have tested something we have not, or publish a specification a manufacturer does not stand behind. If your product data sheet publishes flow against temperature rise, or a measured first hour rating, or an ASSE listing, that is exactly the material these pages are built from and we would like to have it.
