Tankless Units in Shrewsbury Homes

Basement units are standard in Shrewsbury. A buried vent after a storm and a condensate pump that quits are two of the most common no-hot-water calls.

What we run into in Shrewsbury

  • Basement units. Many units here sit in the basement with PVC pipes venting out through the rim joist, and the condensate has to drain somewhere sensible.
  • Snow on vents. Snow drifting against a sidewall vent will stop a unit cold with a venting code until the termination is cleared.
  • Freeze damage. Freeze protection keeps the inside of a unit safe, not the exposed pipes under it. Uninsulated lines are where winter damage usually starts.

Repair or replace

Fix It or Retire It? Deciding in Shrewsbury

Igniters, flame rods, sensors, fans, gas valves and boards are worth replacing on almost any unit. The hard call is a leaking or cracked heat exchanger on an older unit, because that part can approach the price of new.

Read the model and serial off the label and call (380) 273-8196. The age and the fault together usually settle repair versus replace on the phone.

Why Shrewsbury Homeowners Call Us

Parts tested before they're bought

A flow sensor or flame rod gets checked against the maker's values, so you don't pay for a part that wasn't broken.

Scale treated, not ignored

If scale caused the fault, the exchanger is descaled as well, so the same code doesn't return next month.

Run hard before we go

The unit is pushed with several taps open and its outlet temperature watched before the visit ends.

How much does tankless water heater repair in Shrewsbury, MA cost?

Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. Freeze repairs depend on what split, and are priced once the damage is seen.

Why is my tankless water heater not turning on?

First confirm power and gas. If both are there, the usual causes are low flow, a dirty inlet filter, a bad flow sensor or an ignition fault.

Can a tankless water heater be repaired?

Usually, yes. Nearly every part on a tankless unit can be replaced, and a scaled exchanger can be cleaned. The exception is an old unit whose heat exchanger has started to leak.

How often should a tankless water heater be flushed?

Once a year for most homes, and twice a year on very hard water. Soft-water homes can stretch it, but never skip it for years.
