Tankless problems we fix

  • Error codes on the display or the unit shutting off mid-shower
  • Water that swings between hot and cold
  • Low hot-water flow or long waits for hot water
  • Scale buildup from hard water
  • Ignition, venting and gas supply problems

Descaling flush

Hard water leaves scale inside the heat exchanger, which cuts efficiency and triggers errors. Most manufacturers recommend flushing a tankless unit regularly — in hard-water areas like ours, usually once a year. We'll flush the unit, clean the inlet filter and check that it's running the way it should.

Thinking about switching to tankless?

Tankless heaters save space and only heat water when you need it. They also need the right gas line size, venting and electrical. We'll look at your current setup and tell you honestly whether tankless makes sense for your home and what it would take, with a free estimate.

Frequently asked questions

How often should a tankless water heater be flushed?

In hard-water areas like the Murrieta Valley, about once a year is a good rule of thumb. Check your manufacturer's guidelines too.

Why does my tankless water heater keep showing an error code?

Common causes include scale buildup, a dirty inlet filter, venting issues or a gas supply problem. We can diagnose the code and fix the cause.

Can you convert my tank water heater to tankless?

Often, yes. The conversion may need a larger gas line, new venting or a new electrical circuit. We'll check and give you a free estimate.
