The Gold Standard in Home Comfort: Radiant Floor Heating

Experience silent, luxurious warmth that transforms your living space. We design and install bespoke radiant heating systems for homeowners and builders throughout Seattle, Bellevue, and the greater Puget Sound region.

Why Choose Radiant Heat for Your Luxury Home?

Unlike traditional forced-air systems that circulate dust and create drafts, radiant heating provides a clean, quiet, and comfortable environment. It works by circulating warm water through durable tubing embedded in your floor, turning your entire floor surface into a gentle, even heat source. This is the pinnacle of home heating technology.

Silent, Pervasive Warmth

Enjoy a peaceful home free from the noise of fans and blowers. Heat rises naturally from the floor, eliminating cold spots and creating a uniform sense of comfort.

Superior Indoor Air Quality

Because radiant heat doesn’t rely on air circulation, it doesn’t spread dust, allergens, or other airborne particles, making it an ideal choice for a healthier home.

Complete Design Freedom

With no vents or radiators to accommodate, you have total freedom in your interior design and furniture placement. The entire system is invisible, preserving your home’s aesthetic.

Zoned Efficiency

Custom thermostats in every room allow for precise temperature control where and when you need it, enhancing comfort while optimizing energy use.

Our Expertise in Radiant Heating Systems

General HVAC contractors often lack the specialized knowledge required for a flawless radiant heat installation. We are not generalists. We are radiant heat specialists, bringing years of focused experience, technical training, and advanced diagnostic tools to every project.

Custom Radiant System Installation

For new construction projects, we work directly with your builder from the initial plans to design a system that is perfectly tailored to your home’s unique layout and your family’s lifestyle. We lay every foot of tubing and integrate the system with a high-efficiency boiler or air-to-water heat pump, ensuring optimal performance for decades.

Advanced Diagnostics & Precision Service

Is your existing radiant system underperforming? We utilize state-of-the-art thermal imaging cameras to pinpoint “dead spots,” locate circulation issues, and diagnose problems without invasive methods. From fine tuning room temperatures to servicing actuators and manifolds, we have the expertise to restore your system to peak condition.

Your Project, Managed with Precision

We believe a luxury product deserves a seamless and professional process. We manage every detail with clear communication and a commitment to excellence, ensuring your project is a stress-free experience from start to finish.

Step 1: Consultation & Planning

For new homes, we begin by reviewing your builder’s plans to provide a comprehensive estimate. For existing systems, we schedule a diagnostic visit to assess the issue and provide a clear path to resolution.

Step 2: System Design & Proposal

We create a detailed system design and proposal outlining the scope of work, material selections, and project timeline. We answer all your questions to ensure you have complete confidence before we proceed.

Step 3: Meticulous Installation or Repair

Our skilled technicians execute the plan with an unwavering focus on quality craftsmanship. We maintain a clean and organized work site, minimizing disruption to your home and daily life.

Step 4: Commissioning & Final Walkthrough

Upon completion, we thoroughly test and commission the entire system. We conduct a final walkthrough with you to demonstrate its operation and confirm every detail meets our high standards and your complete satisfaction.

Your Radiant Heating Questions, Answered

How long does a radiant heating installation take?

For new construction, the installation is phased in alongside the building process and is scheduled in coordination with your general contractor. For service or replacement work, most projects are completed within a few days, depending on the scope. We provide a clear timeline with every proposal.

How much does a radiant heating system cost?

A full radiant heating system is a premium investment in your home’s comfort and value, with typical new construction systems ranging from $60,000 to $90,000. The final cost depends on the size of your home and system complexity. We provide detailed, transparent estimates for every project.

What kind of flooring can be used with radiant heat?

Radiant heat works wonderfully with most flooring types. Tile, stone, and polished concrete are excellent conductors of heat. Many types of engineered hardwood, luxury vinyl plank (LVP), and even certain carpets are also compatible. We can advise on the best choices for your project.

How do you find a problem if it's under the floor?

This is where our specialization shines. We use non-invasive diagnostic tools, including a high-resolution thermal camera, to “see” the system’s performance through the floor. This allows us to identify and locate issues like flow restrictions or inactive zones with incredible precision.

Craftsmanship Behind the Comfort

Our mechanical rooms are as clean and organized as our installations are effective. Explore our gallery of past projects to see the quality and attention to detail that define North Sound Boilers & Radiant.

Outstanding experience from quote to completion. David installed all the equipment for our radiant floor heat and hot water in our garage. From thoroughly explaining his quote, to an absolutely beautiful install (who knew mechanical could be a work of art) we were very pleased with the result. Highly recommend.

100% recommend I had David out to do a check-up on our Navient tankless water heater and it was a great experience. He was friendly, professional, and super informative. He not only serviced it, but he also explained what he was looking for, why, and what each result meant. When you're looking for someone to work on water system in your house, this is the kind of service you want.

Solid experience all around working with North Sound Boilers & Radiant. We purchased a home 18 month ago and have had boiler issues off and on. I had another highly reputable heating company out twice to try and sort out the issues but they weren’t able to get to the root of the problem. I contacted North Sound on a Sunday evening during one of our cold spells this winter because our boulder went down and my family and I didn’t have heat. David came over that evening. Amazing service! He got us back up and running and after some trial and error David was able to pin point my problem and come up with a solution. All along communicating very well and being a honest guy. I would absolutely recommend giving them a call for your heating needs.

Our 12-year old Triangle Tube boiler died recently and we contacted David at North Sound. Within 7 days he sent us an estimate and came to our Whidbey Island home to do the work. The work took about 7 hours on day1 and 5 hours on day2. He used an IBC boiler and pretty much replaced ~90% of the old boiler stem (pumps, tanks, lines, etc.) Dave seems to have the competence you would need with such a relatively complex system. Definitely not amateur hour with your gas/propane line, ignition and high temperatures and your water line all converging into this system. Potential for a down wind disaster. I did not shop around as we had used David for prior maintenance and his reviews are excellent. It definitely is not inexpensive - more than my used car cost. David came prepared with all the tools and parts he needed. No breaks. On time, cleaned as he goes. We will definitely use him again if needed. See pics.

Our boiler stopped working meaning we had no heat or hot water. David came out the next day and diagnosed the problem. Ours is an old boiler and the part was not available locally. He ordered the part through expedited overnight delivery and installed it Saturday morning. I recommend North Sound Boilers without hesitation. David is a skilled technician but more importantly a man of integrity.
