The Standard in High-efficiency, Trouble-free Operation!

Aero manufactures a complete range of oil fired water heaters in both center flue and rear flue designs. The center flue water heaters include the CF-32T/A, CF-50T/A and CF-50XR. The CF-32T is the most popular domestic water heater with a firing range of .75 gph and a recovery rate of 104 gph.

Center flue water heaters come with two anode rods, a temperature and pressure relief valve, an overflow tube mounted, a surface mounted operating control (immersion aquastats are available), a high limit control and a flexible and removable baffle for easy cleaning. They deliver from 32 to 50 gallons capacity with recovery rates as high 116 gallons per hour. For the United States the CF-32T and CF-50T water heaters can be shipped as a complete unit with the oil burner and controls mounted and wired. This reduces installation time, and therefore costs.


Our rear flue water heaters come in 30, 50 and 70 gallon sizes and are designed for heavier demand with recovery rates as high as 235 gallons per hour. These water heaters have an immersion aquastat (dual or single). The RF-30 gallon rear flue water heater is used for domestic applications, while the RF-50 and RF-70 gallon models can be used for light commercial application such as arenas, small motels, small apartments of up to 12 suites, and larger homes.

All water heaters have a glass lined tank that has been ASME tested to 300 psi. The working pressure is 150 psi. Combustion chambers in our water heaters can be removed and replaced in the field. Our water heaters use our very efficient and quiet F-AFC oil burners. All our oil burners are certified by the Canadian Standards Association in Canada and tested by ULI in the United States.

Our water heaters are certified by the Canadian Standards Association of Canada. For the United States we have submitted all our water heaters to ETL to be tested according to DOE and New York State Energy Requirements. All of our water heaters firing at .75 gph or less exceed the minimum Energy Factor Requirements and water heaters firing .85 gph or more have a lower standby loss than the maximum allowable standby loss.

CF Series Cutaway

1. Rapid installation with electrical and plumbing connections at top.

2. Bright enamel finish provides outer casing corrosion protection through many years of service.

3. Two magnesium anodes for extra corrosion protection.

4. Surface mounted operating control or available immersion aquastat for precise, easy water temperature regulation.

5. Glass-lined heavy duty steel tank built for long life and low maintenance.

6. Brass drain valve for ease of service.

7. Aero oil burner provides the highest oil-fired efficiency in the industry.

8. High limit control is surface mounted for added safety (on T models).

9. Temperature and pressure relief valve and overflow tube is available on some CF models.

10. Flexible stainless steel baffle is hinged for low-ceiling removal and cleaning; designed for optimum heat transfer.

11. Extra-long dip tube directs flow of cold water to tank bottom for fast heating.

12. High-density fiberglass insulation provides a thick blanket around tank and combustion chamber for more heat retention and maximum fuel efficiency.

13. Ceramic fibre combustion chamber concentrates the flame for a smaller, hotter fire and
faster transfer of maximum heat. The large door allows the chamber to be replaced in one piece.


New Rear Flue Stubby Water Heater

We now have a rear flue stubby 30 gallon water heater. The RF-30S is substantially shorter for those installations with low ceiling and chimney inlet height. The RF-30S is only 49 inches high and the distance from the floor to the center of the flue is just 43 inches. This makes the RF-30S ideal for installation in crawl spaces or basements with low ceilings.


Oil Fired Through-the-wall Vented Water Heaters

In North America there is a movement to through-the-wall vented appliances. We were the first oil fired water heater manufacturer to obtain Canadian Standards Association approval for through-the-wall vented oil fired water heaters. In Canada CSA certification is necessary for through-the-wall vented oil fired water heaters. In the United States ULI listing is only required for the venter and not the entire appliance.

These water heaters can be used in homes without chimneys to replace costly electric water heaters. Aero's optional through-the-wall power venter eliminates the expense of adding a chimney to a new home, or the need to replace a deteriorated chimney in an older house.

All our water heaters are approved for through-the-wall venting. When you order a through-the-wall vented oil fired water heater you will receive a water heater less the oil burner, an oil burner with a delayed oil valve and a draft regulator and a Tjernlund SS1 Side Shot venter.
