Thermatrol in Baltimore: Radiant Heating for Retrofit and New Construction
Thermatrol is a licensed plumbing and heating contractor in the Baltimore area that specializes in radiant floor heating systems, both for new construction and retrofit installation in existing homes. Unlike traditional forced-air HVAC, radiant heating distributes warmth through heated water tubes embedded in floors or installed under finished surfaces, a system that requires both plumbing knowledge and heating design expertise that not all general contractors possess.
What Thermatrol actually does
Thermatrol handles the full spectrum of radiant heating work: design consultation, permit coordination, installation of tubing and manifold systems, integration with boilers or heat pumps, and system testing and commissioning. The company is Maryland-licensed and operates across Baltimore County and the city, serving renovations, new builds, and additions where radiant heat makes economic or comfort sense.
Services and pricing
Radiant heating costs depend heavily on the area to be heated and whether the installation is in a new slab (cheaper) or retrofitted under existing flooring (more labor-intensive). A retrofit installation under hardwood or tile in a 500-square-foot bathroom typically ranges from $4,000 to $6,500 installed, including tubing, manifold, controls, and connection to an existing heating source. A full-house retrofit of 2,000 square feet runs $12,000 to $20,000. New-construction slab systems average $6 to $10 per square foot of heated area, a fraction of the retrofit cost because the tubing goes in before the floor is poured.
Thermatrol does not typically quote over the phone; the company requests a site visit to assess the space, existing heating infrastructure, and feasibility. A design consultation costs $200 to $400 and is usually credited toward the project if you proceed. Maintenance plans, offered annually at $150 to $250, include system inspection, bleeding air from lines, and filter changes.

How it compares to other Baltimore-area plumbing options
Standard plumbing contractors in Baltimore, such as those advertising general service, typically do not install radiant systems; they handle water supply, drainage, and conventional boiler work. A contractor like Roto-Rooter or Pipe Dreams Plumbing can install a new boiler to feed a radiant system designed by someone else, but they do not specialize in the tubing layout and zoning that makes radiant heating efficient. Thermatrol's niche is the design and install of the heating distribution itself. Choose Thermatrol if you want radiant heating from someone who designs it; choose a general plumber if you need basic boiler service or drain repair. The two work together on hybrid jobs: a general contractor might call Thermatrol for the radiant design while handling the conventional plumbing rough-in.
Who it suits and who it does not
Radiant heating works best in homes where you can tolerate 2 to 4 weeks of disruption (retrofit under floors requires removing and replacing flooring, or running tubing in the walls or ceiling cavities of lower stories). It suits Baltimore homeowners who want to eliminate baseboard radiators, reduce dust from forced air, or heat a finished basement that is too cold with central heating. It is not practical for renters, homes with radiant-incompatible flooring (thick carpet reduces heat transfer), or owners unwilling to replace flooring or accept ceiling work. Radiant systems also require a compatible heat source; they pair well with boilers or modern heat pumps but perform poorly with electric resistance baseboard heaters.
The first visit and permitting
Thermatrol typically begins with a consultation visit (1 to 2 hours) to measure the space, inspect the existing heating and plumbing setup, and discuss zoning preferences. You will discuss whether the system ties to your current boiler, a new boiler, or a heat pump. The company then prepares a design drawing showing tubing loops, the manifold location, and control strategy. Once you approve the design, Thermatrol obtains a plumbing permit from the city or county and coordinates with other trades if you are mid-renovation. For retrofit work under existing floors, the company will work with your flooring contractor on timing and surface preparation.
Hours, contact, and logistics
Thermatrol operates Monday through Friday, 8 a.m. to 5 p.m., with emergency service available for existing system failures. The company does not have a walk-in showroom; all work begins by phone consultation. Street parking or driveway access is expected during site visits and installation. Most installations require 2 to 5 days of on-site work, depending on square footage and retrofit vs. new-construction scope.
Thermatrol's focus on radiant design and installation gives Baltimore homeowners access to a specialist system in a market where most plumbing calls go to general contractors unfamiliar with hydronic zoning and tubing layout. It is the right choice if you are committed to radiant heat and want someone who designs and installs it as a primary service, not a side offering.
