Bosch Thermotechnology’s WH36 joins the Tronic line of electric tankless water heaters. The Tronic 5000 WH36 comes with an efficiency rating of 97% and can provide endless hot water for up to two major applications at a time. Like all Tronic 5000 models it can be installed virtually anywhere inside a home to provide whole-house hot water on demand – for the WH36 at 5 gpm. It can also be used in smaller homes and specific home conversion applications with hard-to-reach locations requiring extra hot water: in-law suites, garage apartments, pool houses and office suites with an attached bathroom/shower. They can also be used to provide supplemental hot water for high-flow fixtures. Bosch Thermotechnology.
