Tankless vs tank for a Twin Cities two-story
Categories: Water heaters

Tankless vs tank in Minneapolis is the guide. A 40-gallon gas tank in a two-story Eden Prairie house that added a bath is undersized. A tankless on a half-inch gas line that nobody upsized is also a bad day.
Municipal Minneapolis water is kinder than west-metro wells. Wells need a tighter flush interval. tankless service. Isolation valves — if the original skip them, we add them.
water heater replacement when the tank is open. water heater repair when it is not. gas line if the drop is wrong.

Plymouth and Maple Grove remodels are where this conversation happens weekly.
Questions from this kind of call
How often to flush?
Once a year on city water. Wells may need twice.
Same-day tankless?
Uncommon. Tanks yes. Tankless is a scoped install.
