If your building runs hot water all day, the fuel bill is the real cost of the heater. Condensing high-efficiency units recover heat that older systems send up the flue.

Why high-efficiency pays in commercial buildings
A standard atmospheric gas water heater wastes a large share of its fuel as hot exhaust. Condensing units pull that heat back out of the flue gases before they leave the building, which is why they can reach thermal efficiencies in the high nineties. In a hotel, a laundry, a restaurant or an apartment building that heats water around the clock, the difference shows up on every gas bill for the life of the equipment.
High-efficiency units also vent through PVC or polypropylene rather than metal flue, which often makes a replacement simpler and opens up installation locations that a conventional heater could not use.
What we install
- Condensing storage water heaters from A.O. Smith and State.
- Condensing tankless systems where the load and space favour on-demand heating.
- Heat-pump water heaters for electric buildings that want to cut demand charges.
- Condensate neutralization and drainage, venting, gas piping and controls.
Rebates and payback
Utility and manufacturer incentives change from year to year. We will identify what applies to your project and show the expected payback next to the installed cost, so the decision is made on numbers rather than on a brochure.
Frequently asked questions
How much more efficient is a condensing water heater?
Standard commercial gas heaters run in the low-to-mid eighties percent thermal efficiency; condensing units run in the mid-to-high nineties. Actual savings depend on how many hours a day your building heats water.
Can I replace my existing tank with a high-efficiency unit?
Usually, yes. The main changes are the vent, the condensate drain and sometimes the gas line. We survey the mechanical room and quote the complete job.
Do high-efficiency units need more maintenance?
They need the condensate trap and neutralizer checked and the heat exchanger inspected on a schedule. Our maintenance agreements cover it.

Joe Oliveira stopped by my home, took time to understand the problem that I was having with the unit, went back and discussed the issue with his team of experts and had a detailed work order sent to me with in a day. … Based on the experience that I have had with Progressive Plumbing, Heating & Air, Electrical, I will HIGHLY recommend them for HVAC install and maintenance.
