NOAA's 1991-2020 normals for Tampa International Airport show 433.5 heating degree days and 3,928.2 cooling degree days in an average year, so a boiler here serves a heating season of 433.5 degree days, against 3,928.2 for cooling, in a house that already has radiators or in-floor heat.
Service notes
Key points before you call
- Residential Lennox models listed here: 6.
- Official Lennox public PDFs linked for these options: 9.
- Efficiency as Lennox lists it: GCWB95 at 95 percent AFUE, GWB9-IH at 90 percent, OWB86 at 86 percent, GWB84-E at 84 percent, GWB84-IE at up to 84.4 percent, and GSB8-E at up to 82.7 percent.
- Fuel: five models list natural gas, convertible to LP on four of them; the OWB86 is oil-fired.
- Type: the GSB8-E is a steam boiler, the GCWB95 is a combination boiler that supplies heating and hot water, and the others are water boilers.
- Venting: Lennox lists chimney venting on the GWB84-E and chimney or side wall venting on the GWB84-IE; the GWB9-IH and GCWB95 are condensing models.
- Lennox says the boilers work with an existing radiator system and, for the GSB8-E, under-floor heating.
Which Lennox boilers fit Tampa homes?
Check that the house heats with water or steam at all. Lennox describes these boilers as working with an existing radiator system, and the GSB8-E with under-floor heating as well, so they answer a replacement question for a hydronic house and not a new-build choice for a ducted one. The remaining questions are fuel (gas or oil), whether the existing chimney can be reused, and how much capacity the radiators actually need.
How to compare these models
Compare in this order. Type: steam (GSB8-E), combination (GCWB95), or water. Fuel: natural gas or oil (OWB86). Efficiency: 95 percent AFUE on the GCWB95 down to up to 82.7 percent on the GSB8-E. Venting: condensing models and the chimney-vented GWB84-E versus the GWB84-IE, which lists chimney or side wall venting. Capacity: the GCWB95 lists 22 to 150 and 29.5 to 205 mbh sizes, and the others list six, three, seven or nine burners or sizes.
Lennox model details and PDF downloads
This category includes 9 Lennox PDF downloads across 6 models. Each model links the PDFs Lennox makes available. Every boiler links a Lennox product brochure, and the GCWB95, GWB84-E and OWB86 also link a homeowner's manual.
Air Strike service that matches Lennox boilers
The closest Air Strike service is heating repair. Boiler work is hydronic, so ask Air Strike to confirm it can quote the specific boiler, fuel and venting scope before relying on this list.
Questions to answer before a quote
Settle the facts the quote depends on: gas or oil, steam or hot water, the age and condition of the radiators and piping, the chimney or vent route, the electrical and fuel connections, and what happens to hot water if the existing boiler also supplied it. A like-for-like swap and a change of boiler type are different scopes.
Cost, permit, rebate, and warranty questions for Lennox boilers
Use the six models for budget screening only. A condensing model, a combination boiler and an oil-fired boiler differ in more than price, because they change the vent, drain and piping scope. Lennox shows price-guide symbols, not dollar amounts. Fuel, venting, piping and permit handling sit in the written scope, along with rebate eligibility, warranty registration and permit responsibility.
Next Air Strike steps for Lennox boilers
Start with Air Strike's heating repair service to review the existing system and confirm that a boiler request can be quoted. For a house moving to ducted heating and cooling instead, Tampa AC replacement and Hillsborough County HVAC replacement cover the sizing, airflow and permit questions.
Questions to bring to the quote
Ask the proposal to name the model and fuel, steam or water, the capacity chosen and the load behind it, the vent or chimney work, the piping and pump changes, the fuel connection, the electrical supply, condensate handling for condensing models, and who handles the permit.
When to use an individual model
Open a single model when the type is settled. The GCWB95 is the condensing combination boiler with direct spark ignition. The GWB9-IH is a condensing water boiler with a cast-aluminum heat exchanger. The GWB84-E and GWB84-IE are standard-efficiency water boilers. The GSB8-E is the steam model. The OWB86 is oil-fired and lists an optional tankless coil for hot water.
Repair-vs-replace questions before choosing Lennox boilers
The repair-vs-replace call on a boiler starts with the symptom. A boiler complaint can start with a pump, a zone valve, an ignition part or low water, which are repair items. Replacement is a question of the heat exchanger, the system's age and the piping. Ask the written scope to say what failed and whether the new boiler changes the fuel, vent or piping.
What to confirm before choosing Lennox boilers
Before choosing a boiler, confirm the model, fuel, venting, availability, pricing, rebates and warranty terms with Air Strike Cooling, and check Lennox's listing for the latest figures.

Homeowner questions
FAQ
Can Air Strike quote a Lennox boiler in Tampa?
Air Strike Cooling can review a Lennox boiler request for a Tampa or Hillsborough County address and confirm whether it can quote the job. Availability, installation scope, warranty details, rebates and final pricing must be confirmed directly.
Does a Tampa house need a boiler?
Only a house with hydronic heat does. Lennox describes these boilers as working with an existing radiator system, and a ducted house heats and cools through the air handler instead.
What is the difference between the water, steam and combination boilers?
Lennox lists the GSB8-E as a gas-fired steam boiler, the GCWB95 as a modulating gas-fired condensing combination water boiler that supplies heating and hot water, and the others as water boilers.
Which boiler runs on oil?
The OWB86 is an oil-fired water boiler listed at 86 percent AFUE with an optional tankless coil for hot water. The other five list natural gas.
How efficient are these boilers?
Lennox lists 95 percent AFUE on the GCWB95, 90 percent on the GWB9-IH, 86 percent on the OWB86, 84 percent on the GWB84-E, up to 84.4 percent on the GWB84-IE and up to 82.7 percent on the GSB8-E.
Which boilers can vent through a side wall?
Lennox lists chimney or side wall venting on the GWB84-IE and chimney venting on the GWB84-E. Confirm the vent route for any model with the written scope.
Where are the Lennox PDFs for these boilers?
Every boiler links a Lennox product brochure, and the GCWB95, GWB84-E and OWB86 also link a homeowner's manual. Open the individual model for the links.
What does a boiler replacement cost, and who handles the permit?
A model list is not an installed price. The written scope should list the boiler, fuel and vent work, piping and removal, and permit responsibility is confirmed in that scope before work starts.
