A tankless water heater heats water as it flows, so you stop running out when the tank is empty. In return it needs the right gas supply, venting and, in many homes, regular flushing. We install, repair and descale tankless units in Willingboro and answer the phone 24/7.
Is tankless right for your house?
Tankless works best when the gas line, vent path and wall space are ready for it. Many older homes need a larger gas line or a new vent, and those costs belong in the price before you decide.
| Question | What to check | Why it matters |
|---|---|---|
| Gas line size. | Pipe diameter and meter capacity. | Undersized lines starve the burner. |
| Venting. | Path to the outdoors. | Tankless units need approved vent materials. |
| Incoming water temperature. | Winter inlet temperature. | Colder water lowers the flow a unit can heat. |
| Flow demand. | Fixtures that run together. | Sets the unit's required rating. |
Flushing and descaling
Mineral scale builds up inside the heat exchanger and slows the unit. Flushing with a circulating pump and a descaling solution removes it. How often depends on your water, so check the Willingboro Municipal Utilities Authority's annual water quality report at wmua.info and test your tap rather than guessing.
- Shut off power, gas and water to the unit.
- Connect a pump and hoses to the service valves.
- Circulate descaling solution through the exchanger.
- Flush with clean water and clear the inlet filter.
- Restart the unit and check for error codes and flow.
Common tankless problems
Cold water sandwich
A brief burst of cold water between hot flows can be settings, a scale problem or a flow sensor.
Error codes
Codes point to ignition, venting, flow or sensor faults, and the manual maps them.
Reduced flow
Scale or a clogged inlet screen is a frequent cause.
Noise or odd smells
Combustion issues need prompt attention. Turn the unit off if you smell gas.

Cost factors for tankless work
If your tankless unit has failed beyond repair, we compare a new tankless unit against a tank on our replacement page. For minor faults, see water heater repair.
Questions to ask before you buy a tankless unit
Ask for the maximum flow rate at your winter inlet temperature, not the number on the box. A unit rated for a high flow in summer can deliver noticeably less when the incoming water is cold, and January in this area is cold. Ask how many fixtures can run together before the temperature drops, and compare that to how your household really uses water in the morning.
Ask what the quote includes. Venting, a gas line upgrade, a condensate drain, a service valve kit and haul-away of the old tank are separate line items on many tankless jobs. A low headline price that leaves them out can end up higher than a complete quote. Ask who handles the permit question as well, since permit rules vary and the Willingboro building department decides what applies to your project.
Finally, ask about service. A tankless heater is a maintained appliance, and a yearly flush is the most common request we hear about. If your water is hard, ask how your plumber will check the scale and what the unit's manual says about intervals. If you already own a unit that is throwing codes, describe the code when you call and we will tell you whether it sounds like a flush, a part or a larger repair.
Questions Willingboro homeowners ask
How often should a tankless water heater be flushed?
It depends on your water. Many makers suggest yearly. Test your tap and read the water quality report from the utility to judge how fast scale forms.
Can you convert my tank to tankless?
Often, yes. The gas line, vent path and electrical needs decide the cost, and we check them before quoting.
Why does my tankless heater show an error code?
Codes point to a specific fault such as ignition, venting, flow or a sensor. Tell us the code and we can narrow it down before the visit.
Is tankless safe in an older Willingboro home?
Yes when installed with the right gas line, vent and clearances. Older homes may need upgrades, which we put in the quote.
We service tankless units in Westampton and Burlington Township. A drain cleaning visit is unrelated, but we can handle condensate drain clogs too.
