WHY HOMEOWNERS CHOOSE COMBI UNITS
A Smarter Way to Heat Your Home and Water
A combi unit handles your home heating and domestic hot water from one compact, energy-efficient appliance. For Baltimore homeowners with limited mechanical room space or aging dual systems, the upgrade pays off in lower bills, better performance, and a cleaner utility space.
-
Space-Saving Design
Combi units mount on the wall and eliminate the need for a separate boiler and tank water heater. That frees up valuable square footage in basements, closets, and utility rooms throughout row homes and townhouses across the city.
-
High Energy Efficiency
Modern combi units run at efficiency ratings above 90%, heating water only when needed. Lower gas usage means lower monthly bills, especially during Baltimore's long heating season.
-
Endless Hot Water
Because the unit heats water on demand, you never run out mid-shower. Combi systems are an excellent fit for busy households that want tankless water heater performance paired with hot water heating for radiators or radiant floors.
-
One System, One Service Call
When heating and hot water come from the same unit, future maintenance and repairs are simpler. One trusted plumbing and heating contractor handles everything.

FREQUENTLY ASKED QUESTIONS
Combi Unit Questions, Answered
Here are answers to the questions Baltimore homeowners ask most about combi boiler installation, performance, and service.
What is a combi unit and how does it work?
A combi unit is a single wall-mounted appliance that provides both home heating and on-demand domestic hot water. It heats water as you need it for showers, sinks, and appliances while also supplying hot water to radiators or radiant floor loops, eliminating the need for a separate boiler and tank water heater.
How long does a combi unit installation take?
Most combi unit installations are completed in a single day. Timelines can vary based on gas line modifications, venting routes, and the condition of existing hydronic piping, but our team works efficiently to restore heat and hot water as quickly as possible.
Are combi units a good fit for Baltimore row homes?
Yes. Their compact, wall-mounted design is ideal for the tight basements, closets, and utility rooms common in Baltimore row homes and townhouses. Combi units free up floor space while delivering strong heating and endless hot water performance.
How much can I save on energy bills with a combi unit?
Modern combi units operate at efficiency ratings above 90%, and because they heat water only on demand, you avoid the standby losses of a traditional tank. Most homeowners see meaningful reductions in monthly gas usage, especially through Baltimore's long heating season.
How often should a combi unit be serviced?
We recommend annual maintenance to keep your combi unit running safely and efficiently. Yearly tune-ups include descaling, inspecting the heat exchanger, checking gas pressures, and verifying venting, which extends the life of the system and helps protect the manufacturer warranty.
Can you repair my existing combi unit if you didn't install it?
Absolutely. Our heating contractors service all major combi unit brands, including ignition faults, error codes, pressure issues, flow sensor problems, and descaling. Call (443) 413-4117 and we will get a technician out to diagnose the issue.
