Overview of OH8

The Thermo Pride OH8 is an oil-fired, low-profile highboy boiler with an efficiency rating of up to 86% AFUE. Models of the OH8 come with a factory standard PSC blower motor, and an optional ECM motor which operates at lower speeds is available for increased efficiency. The heat exchanger is constructed of 13 gauge copper-coated steel in an octagonal shape for improved heat transfer. The unit features high efficiency controls mounted at the front of the cabinet for easy setup and service.

Poor performer

I replaced an old Coleman oil-fired forced air furnace with the Thermo- Pride OH8. While it seems to put out a good amount of heat, the AFUE is 85% (expected), but the actual efficiency of the unit in putting heat into the house is very poor. My oil usage is up over 40% since it was installed. There has been a consistent hot-oil smell from the unit after it shuts down, with three return visits by the installer. Thermal mass is nice, but not in the unit. The thick gauge, octagonal heat exchange unit does NOT exchange heat with the house air very well. It takes a long time to reach temperature, and sends a disgusting amount of heat out the flue pipe. Don't be fooled by AFUE: That is just how efficiently the burner and chamber convert your fuel to heat. If that heat goes out the flue, then you are far less efficient in heating your house. I'd take the old cheap Coleman unit back in a minute.

Best bang for your buck Thermo Pride OH8

Replaced 7 year old Lennox warm air furnace. Noticed lower consumption of power and oil. ECM blower motor option: Significant energy savings (67% average compared to psc motors). 13-Gauge large surface area Octatherm Heat Exchanger copper plated for corrosion resistance. Overall good quality manufacturing of sheet metal and clean out ports. Best bang for your buck for warm air furnaces on the market today. Make sure your technician sets the blower speeds to applicable fire rate and a/c capacity.

Other OH8 Reviews

Among the very few online reviews of the OH8 on HVAC forums, a consumer on having problems with his blower eventually discovered that the problems were being caused by the thermostat.
