Tankless Water Heater Services in DeMotte, IN

On-Demand Hot Water, Installed and Serviced Locally

Hot Water Without the Storage Tank

A tankless water heater heats water on demand rather than storing it, which removes the storage tank and frees up the space it occupied. Krooswyk installs and services Navien and State tankless systems, with plumbing work performed under Indiana license CO51500007.

Tankless equipment also brings its own maintenance needs. Mineral buildup and scaling is the issue we address most often, especially on the harder well water common on rural properties, and left alone it shows up as low hot water pressure and error codes on the display.

Frequently Asked Questions
Tankless Water Heaters

  • How often does a tankless water heater need descaling?

    Regularly, and more often on the harder well water found on rural properties around here. Mineral buildup and scaling is one of the most common tankless problems we address, and left alone it shows up as low hot water pressure and error codes. Descaling is scheduled service rather than a repair.

  • What does an error code on my tankless unit mean?

    Tankless systems self-diagnose and report faults as codes, which is genuinely useful because it narrows the problem to combustion, water flow, venting, ignition, or a specific sensor before a technician arrives. Have the model number and the code ready when you call and we can often tell you what is involved beforehand.

  • Can I replace my tank water heater with a tankless unit?

    Often yes, but it depends on the gas supply, the venting route, and your hot water demand. A tankless unit draws differently from a storage tank, so the existing gas line and vent are not always sufficient without modification. We check all of that before quoting the work.

  • Do you service tankless water heaters you did not install?

    Yes. We repair and maintain tankless equipment regardless of who installed it. Navien and State are what we carry for new installations, but service work is not limited to those brands.
