There is quite a debate in the plumbing industry to decide if tank or tankless units are the best value for your new modular residence or office with showers. There are pros and cons of both units, so we offer a little research from one of the tankless manufacturers Rinnai. Watch this video and you can decide which you prefer for your new modular facility.
We have provided many tankless and tank water heaters over the years. If you have hard water we also recommend looking at a water softener system to add to life cycle. There are also circulation pumps and other options available to accelerate your heating process. 
Let our design and preconstruction team help you with options and ideas for your new modular facility.
