Plumbing + Heating Experts Serving Utah Since 1933

Thornton Plumbing and Heating Inc. was established as a plumbing and heating company in 1933. As one of the oldest plumbing companies in Utah, we started installing hydronic heating systems when the old style cast iron radiators were the most common type of heating system around. In the 1940s and 50s we started installing radiant floor systems with welded steel piping under the concrete slab. In the late 1980s (when radiant floor heating made a comeback) we were at the forefront of the radiant revolution! We’ve adapted our services with the changing technologies to ensure our customers are always receiving the most modern, convenient, and energy-efficient hydronic systems, from radiant floor heat to snowmelt systems.

Over the years, customers have come to expect our prompt and friendly service, straight talk without the sales pitch, and genuine care and compassion as we work to resolve your heating and plumbing concerns. We don’t just want to be “any old service company;” we want to be exceptional at installing and maintaining radiant heat and snowmelt systems, boilers, and plumbing systems. Contact us today.

Our Rich History

Thornton Plumbing and Heating was established as a plumbing and heating company in 1933 in the midst of the Great Depression. Charles W Thornton and Grace G Thornton together declared that “Progress and Success come only if you make it happen!”

Thornton Plumbing and Heating started out with one panel truck to get Charles and his tools to and from work. The suppliers sought Charles and Grace’s business. It was known in the industry that Charles, work was good and many expressed to the community that Charles was an honest man. By 1959, Calvin Charles Thornton took over the business.

Calvin maintained his fathers, standards for accuracy and honesty and was well respected in the community. His integrity and character were top notch. Calvin was known as being a man who was willing and eager to serve others. He had high expectations for his employees and required only the best from them.

In 1997 Clay Thornton (Calvin’s son) and Ken Barney took over the company. Together they grew Thornton Plumbing and Heating into an industry leader not only in Utah but nationwide. They have both been on the cutting edge of progress in the Radiant specialties.

In October of 2017 Ken Barney and Ellen Thornton Barney took over Thornton Plumbing and Heating together. Our children have all worked for our company. They are the 4th generation of this great legacy started by a man with a vision and the posterity to carry on that vision.

A note to relay the excellent job Jordan Walker did repairing a leak on the water pipes in my condo. He also noticed an issue with my water heater and repaired a critical vent. This was an after-hours call, Jordan responded promptly, diagnosed the problem and was able to fix the leak quickly and expertly. His manner was friendly, skillful and informative. Thank you, Jordan, and thank you Thornton Plumbing and Heating. Lance Paulson

We used them to repair a shower steam generator. Jordan Walker was outstanding. He diagnosed the problem and had it repaired on the spot in no time. I will definitely use this company and request Jordan for all my plumbing work.

Worked in the building trades or 40+ years. Some new construction, mainly residental renovation. I "collect" good subcontractors. There are a lot of less desirable contractors now. Clear, concise & know how to perform. I now recommend them to friends & family.

Radiant Floor Heating: A Comfortable and Efficient Heating Solution for Utah Homes

Radiant floor heating has become an increasingly popular heating solution for homes in Utah. This type of heating system uses a series of pipes or electric heating elements installed beneath the floor to distribute heat evenly throughout a room.
