Tell us what’s happening
What do you need from the system?
Start with the model and concern, or the fixtures you expect to run together.
- An existing error or shutdown
- A displayed code helps focus testing; it does not by itself establish which part needs replacement.
- Flow and temperature rise
- Bathroom count alone does not establish output. Compare combined demand at incoming-water conditions.
- Waiting at the tap
- Water still travels through the pipes. Recirculation needs a suitable design and controls.
Before you agree
What should the work include?
Review what the work addresses, the equipment and connections involved, and what is excluded. The proposed work and price should be clear before you approve it.
Tank, tankless and hybrid comparison- Model and supply requirements
- We’ll specify the tankless heater and relevant fuel/electrical changes. A combi-boiler or heating boiler performs a different job.
- Venting, drainage and piping
- Explain routes, service access and any proposed recirculation arrangement.
- Full scope and actual terms
- Include the complete installed price, applicable permits, operation checks and model-specific written coverage.
What affects the work and cost?Demand at the incoming-water temperature, fuel supply, venting, drainage, piping and any recirculation design affect the proposed tankless work.

Before you decide
Questions before deciding
Review the common questions and explore simultaneous fixture use with the hot-water planning tool. A water-heater recommendation also needs demand, temperature-rise and installation checks.
Is Navien tankless service the same as combi-boiler work?
No. A combination appliance also connects to space heating, so controls, distribution and water-heating demands interact. Confirm the exact model and supported scope before arranging work. For tankless care, discuss descaling, inspection, service valves and what is separately charged.
Does an error code identify the part to replace?
No. It helps focus investigation. The heater and connected water system need checks before parts or replacement are recommended.
Will a Navien heater make hot water instant?
Water still travels through the piping. Discuss a suitable recirculation arrangement and its controls if wait time matters.
How often does it need descaling?
Follow the selected model’s guidance and water conditions. Confirm an appropriate service plan rather than assigning one interval to every installation.
