Heat Loss Sizing
We calculate heat loss room by room and match boiler output to your emitters, preventing oversizing that causes short-cycling and keeps condensing boilers from reaching their best efficiency.

Boiler Installation in Roswell, GA
Boilers deliver quiet, even heat without blowing air, which is why many homeowners choose them for additions, new construction and older homes with radiators. Our boiler installation in Roswell service covers new hot water boiler systems from the ground up, whether you are adding hydronic heat for the first time or building around radiant floors. We calculate room-by-room heat loss, select a boiler with the right output and turndown, and decide between a high-efficiency condensing boiler, a conventional cast iron model or a combination boiler that also supplies domestic hot water. Our installers build the near-boiler piping with primary-secondary loops or a hydraulic separator, install the expansion tank, air separator, circulators and relief valve, and set up zoning with valves or pumps. Gas-fired boilers are vented to code and tested for carbon monoxide before we leave.

Condensing Boiler Options
Modulating condensing boilers adjust output to demand and recover heat from exhaust gases. We explain when they shine, especially with radiant floors and other low-temperature systems.
Combi Boiler Installation
A combination boiler provides both space heating and on-demand domestic hot water from one compact wall-hung unit, freeing floor space and eliminating a separate tank water heater.
Near-Boiler Piping
We build clean, well-supported piping with air separators, expansion tanks, backflow prevention and hydraulic separation, so water flows correctly and the system stays quiet for years.
Zoning and Controls
Zone valves or dedicated circulators let you heat bedrooms, living areas and basements separately. We add outdoor reset controls that adjust water temperature to match the weather.
Venting and Combustion Test
We install sealed venting to manufacturer specifications, set gas pressure, and run a combustion analysis that confirms clean burning and safe carbon monoxide levels before startup is complete.
Why Choose our Boiler Installation Experts in Roswell
A boiler is only as good as the piping and controls around it. We design each installation as a complete hydronic system, paying close attention to flow rates, water temperature and air removal, so you get the quiet, even comfort boilers are known for without banging pipes or cold rooms.
Our installers take pride in neat, labeled mechanical rooms that are easy to service later. You receive a clear proposal, careful work and a full walkthrough of the controls, pressure gauge and zone thermostats. For gas boilers, combustion testing and carbon monoxide detector recommendations are part of every job, never an afterthought. We also coordinate closely with builders, plumbers and flooring installers on new construction or additions, keeping the project on schedule and making sure radiant loops and emitters connect correctly to the new boiler.

FAQ
Boiler Installation FAQs
Answers to the questions Roswell customers ask us most. Still unsure? Call (770) 661-0066.
Is a boiler a good choice for heating a home in Roswell?
A boiler is a good choice when you value quiet, even heat without blowing air, or when you plan radiant floors. It is less common in metro Atlanta because most homes rely on ducted air conditioning, so a boiler is often paired with a separate cooling system. We help you weigh comfort, installation scope and operating cost.
What is the difference between a combi boiler and a regular boiler?
A regular boiler only heats water for your heating system, and domestic hot water comes from a separate water heater or storage tank. A combi boiler does both, heating space and supplying on-demand hot water from one compact unit. Combi boilers save space, but larger households with heavy simultaneous hot water use may need extra capacity.
How long does a new boiler installation take?
Installing a boiler in a home that already has hydronic piping typically takes one to two days. A completely new hydronic system with radiators or radiant floors takes longer, often several days, depending on the number of zones and emitters. We give you a detailed timeline during the proposal so you can plan around the work.
What determines the cost of a boiler installation?
Major factors include boiler type and efficiency, output capacity, the number of zones, whether new emitters or radiant tubing are needed, venting requirements and the fuel source. Combi units and outdoor reset controls also affect the total. We design the system first and then provide a written, upfront quote that lists equipment and labor clearly.
Do gas boilers need special venting?
Yes, and the type depends on the boiler. Condensing boilers use sealed PVC, polypropylene or stainless venting that can often exit through a side wall, while some conventional boilers vent into a lined chimney. Correct venting is essential for preventing carbon monoxide problems, so we follow the manufacturer's requirements exactly and test combustion after installation.
