A homeowner who paid to replace an old water heater with a tankless model turned to the internet after the setup appeared unfinished.

Here's what to know

"It was a Borch Hydropower before. The job is done, but it just doesn't look done professionally. Asking professional plumber for opinion," the original poster wrote.

A commenter argued that the installation was missing essential hardware, writing: "Any professional installation should have an isolation valve kit. You can never flush your unit with this setup."

Another user flagged whether the gas line could deliver enough BTUs. "The manufacturer will not honor a warranty with this installation," they said.

Upgrading to a heat pump water heater offers homeowners an effective way to lower energy bills.

More background

Tankless water heaters can be efficient, space-saving upgrades, but they are not maintenance-free.

A poor installation can shorten the unit's lifespan; make routine service difficult; or lead to added costs if a technician has to redo piping, valves, or gas connections.

This post showed that a low installation price is not always the best route. When important components are left out to save time or money, a system can be costly to deal with over its lifespan.
