Some homeowners would prefer not to have pipes running through their living rooms or bedrooms when they cannot even use that space (and heating/cooling ducts) during winter and summer months. A gas line installation may be required with a tankless system that does not already exist (read more about it here – link). On top of that, with this type of unit it’s usually only one faucet that can be used at a time. For example, if you want to run a bath and wash your hair with the shower on, you can’t do so – someone taking a bath will have no hot water.

Depending on how your home is wired, additional circuitry might need to be added before installation so know exactly what’s involved beforehand. And if you’re not comfortable with making those types of changes yourself, don’t hesitate to call an electrician!
