Tankless Water Heaters
Does anyone have experience with using tankless hot water heaters, like this one, in a residential application? My house has 3 bathrooms, one of which has a 100 gallon soaking tub that is filled with a high flow rate (12 gpm) faucet. http://www.takagi.com/products/tankless-water-heaters/t-m50-n “The T-M50 Series, specifically designed for heavy-duty applications, is the largest Takagi tankless heater yet, and the most powerful (14.5 GPM max) in the tankless industry! The T-M50 Series is suitable for commercial applications (hotels, restaurants, government, convalescent homes, etc.) that require high demand and the most durable of heaters. Along with HRS35 copper alloy, the T-M50 Series is the only commercial unit in the industry that offers a “dual-combustion system,” providing redundancy for added reliability”

As the other posters said…this a unit usually installed in a restaurant or similar high use location. Unless you have an appropriate gas service and meter bar you would need a dig up and new service to even think about installing the unit

You probably haven’t got the gas meter to supply that heater and you probably don’t have the clearance from doors and windows to vent it through a side wall. So, you’ll have to vent it to the roof but you can’t use the chimney for that because it’s being used by something else. https://heatinghelp.com/heating-museum/tankless-water-heaters/

That little beauty takes 380,000 btu, over double what a house boiler uses. Should be easy to install…
