Boilers, Hydronics & Radiant Heating Services in Kent, WA

When it comes to consistent, energy-efficient heating, boilers and hydronic systems remain one of the most reliable choices—especially in the Pacific Northwest climate. At Design West Mechanical , we specialize in the installation, repair, and maintenance of boilers, hydronic heating systems, and radiant floor heating for homes and businesses throughout Kent, WA and surrounding communities.

Whether you’re upgrading an older system, installing radiant heat in a new build, or need expert repair, our licensed plumbers deliver precision work and outstanding results backed by years of experience.

Boiler Installation & Replacement – Built for Long-Term Comfort

A properly installed boiler offers powerful, even heating without the drafts and noise common with forced-air systems. At Design West Mechanical , we install all types of boiler systems including:
  • High-efficiency condensing boilers
  • Gas and electric boilers
  • Combination boilers (combi units)
  • Steam boilers (for select applications)
  • Wall-mounted or floor-standing models
Our experts will help you choose the right size and type of boiler based on your heating needs, home layout, and energy goals. We handle all the plumbing, venting, controls, and zoning work to ensure your system operates safely and efficiently from day one.
If your current boiler is aging, struggling to keep up, or experiencing repeated breakdowns, we also provide complete boiler replacement services with a smooth, code-compliant installation process and disposal of the old unit.

Hydronic Heating – Efficient, Quiet, and Versatile

Hydronic heating uses heated water circulated through sealed pipes to warm your home or business. It’s a clean, efficient alternative to forced-air heating—and it can be configured in several ways, including:
  • Radiator systems
  • Baseboard heaters
  • In-floor radiant heating
  • Snow melt systems for driveways and sidewalks
  • Heated towel warmers and specialty applications
Because it uses water instead of air, hydronic heat provides consistent warmth without blowing dust or allergens—making it a great option for allergy sufferers or anyone looking for a quieter, cleaner heating solution. These systems are also highly customizable with zoning controls for targeted comfort room-by-room.
At Design West Mechanical , we design and install complete hydronic systems for new construction, retrofits, and remodels. We’ll help you build a heating solution that enhances comfort, improves air quality, and reduces your energy costs.

Radiant Floor Heating – Invisible Comfort Underfoot

Few upgrades match the comfort and luxury of radiant floor heating. Imagine warm tile or hardwood floors on chilly mornings—radiant heat makes it possible. We install both hydronic and electric radiant floor heating systems, ideal for:
  • Bathrooms
  • Kitchens
  • Basements
  • Whole-home applications
Radiant heating works silently and evenly across a room’s surface, eliminating cold spots and delivering comfort where you need it most. It’s also energy-efficient and can work seamlessly with your boiler or heat pump.
Whether you’re adding radiant floors during a remodel or incorporating them into a new build, Design West Mechanical offers the expertise to ensure smooth, leak-free installation and lasting performance.

Boiler & Radiant Heating Repairs & Maintenance

Common issues we fix include:
  • No heat or insufficient heating
  • Uneven heat distribution
  • Leaks in piping or fittings
  • Noisy operation
  • Thermostat or control failures
  • Pressure or pilot light problems
Regular maintenance is the best way to prevent costly repairs. Our tune-ups include inspections, flushing, pressure checks, and part replacements as needed to keep your system running smoothly, safely, and efficiently.

Great experience with Design West Mechanical! Called late on a Saturday evening and talked to Joe. Since it wasn't an immediate emergency, we agreed to address the issue on Sunday. Joe called to confirm in the morning, arrived 15 minutes later, and replaced the parts by noon. The repair cost was reasonable and Joe was professional and personable. I would recommend their services.

I had a floor drain backup and flood part of my basement on a Tuesday evening, I called and Joseph was out the next morning to start diagnosing and fixing the problem. The clean out was in a very odd spot under a cabinet and he was able to come up with a solution to get to it and snake the pipes without having to remove the the full cabinet. He was able to clean the pipe and also show me the integrity of the pipe and location of the pipes with his camera and locator. I will definitely be calling them for any of my future plumbing needs.

Design West Mechanical, specifically Joe and Tarryn, are professional, trustworthy, and fair. My wife and I had Joe "hook-up" a natural gas line to run our generator. It worked out so well during the " bomb-cyclone" event! Thank you Joe and Tarryn for keeping my family warm and safe. I highly recommend Joe and Tarryn of Design West Mechanical.

Responded quickly, did a good job replacing a dead sump pump, very easy to work with. Did job for quoted reasonable rate, didn't charge for follow-up visit next day. Very impressed. He also gave some ideas for lowering our need for a sump pump.

Accountable and very knowledgeable cuts to the chase. Love working with Joseph and crew gets the job done right every time. I used to hate calling a plumber they always give you the go around always want to do extra work that doesn’t need to be done. Calling them is peace of mind knowing that the job will get done right the first time.
