Navien Maintenance and Repair
Janes Radiant Heating specializes in providing fast Navien emergency service and maintenance anywhere in Western Washington, anytime you need it. Our experienced maintenance and service technicians are factory trained and certified to properly diagnose, repair, or replace Navien boilers, combi tanks, tankless water heaters and other radiant heating components.
Like any other mechanical system, radiant heating systems experience wear over time. Many of our customers choose to have an annual scheduled maintenance to ensure their Navien boiler or tankless water heater is always running at maximum efficiency. During these checkups, Janes Radiant Heating will look over the pumps, valves, gauges, manifolds and other system components to make sure they are working properly and are not likely to leak. We perform a cleaning and adjustment service on boilers and tankless heaters and ensure your thermostat is working properly. This routine maintenance will help keep your radiant heating system running in optimal condition.
We stock the largest selection of hydronic heating system parts in the Northwest to ensure fast, efficient repair turnaround times.
Janes Radiant Heating is 100% focused on radiant heating. Since 1987, we’ve specialized in the issues that stump other contractors—from underperformance and system leaks to full diagnostic assessments.
We offer competitive rates and provide high-quality work backed by a workmanship guarantee. Our scheduling is flexible, our service responsive, and our reputation backed by decades of trust across Western Washington.
From natural gas and propane to electric and geothermal systems, Janes Radiant Heating has the expertise to service all types of hydronic heating components.

What Our Customers Are Saying on Google
We have a 1996 vintage radiant heating system. I called Jane’s on a freezing Valentine’s Day and Lucille found a tech immediately. Jesse arrived within 45 minutes and fixed the issue without upselling. He explained everything clearly — I now understand my system better than ever. Exceptional service!
I highly recommend Janes Radiant Heating. Jesse came the same day we lost heat and hot water. He fixed everything efficiently and took time to explain the process. Super knowledgeable and friendly. Thanks Jesse & Janes!
Jesse did an amazing job fixing a system that hadn’t worked for 8 years. He flushed and maintained the hydronic system, and my room finally reached 75°F. Highly recommend his professionalism and skill!
Jesse at Janes Radiant was amazing. He handled an urgent issue swiftly, explained the whole process, and put me at ease. First-rate service and communication. Thank you!
I’ve always had great service from Janes. Michelle recently helped fix issues and walked me through the system operation. Super friendly and professional. Highly recommended!
Fantastic customer service! Louise was cheerful and patient even when I checked multiple times a day for updates. Michelle was courteous, respectful, and did an excellent job. We got our heat and hot water back! Thank you!
