Glossary

Listed below are terms common in the heating industry.

AFUE: Abbreviation for “Annual Fuel Utilization Efficiency,” it is an energy-efficiency ratio comparing the useful energy produced by an appliance in a year with the amount of energy it consumes.  Thus, the higher the AFUE rating, the better the efficiency

Boiler: A gas, oil, propane, or solid-fuel-burning appliance that produces hot water or steam which is circulated through pipes to heat-radiating devices in a room.

Bill-Pay:  An automatic payment system that conveniently pays Roach Energy Budget Plan payments directly from the customer’s bank account.

BTU: Abbreviation for “British Thermal Unit,” it is a traditional measurement for the amount of heat needed to raise one pound of water 1° F from a starting point of 39.2°F. BTUH stand for British Thermal Unit Per Hour to measure BTU input or output over time. MBH stands for 1,000 BTUH.

Carbon Monoxide:  A colorless, oderless gas that affects the central nervous system and can cause death through asphyxiation. Carbon Monoxide can be produced by improperly vented or poorly adjusted propane appliances.

Convected Heat: Warmth transmitted to a colder body through physical contact with a substance, such as air.

Degree Days: The difference in temperature between 65° F and the average temperature over the previous 24-hour period. For example, if the average temperature over the previous 24-hour period was 30°F, 35 degree-days have elapsed.

Fuel Oil: #1 or #2 grade diesel fuel that is burned to produce heat.

Hydronic: Refers to temperature control systems that circulate heated or cooled water to maintain comfort.

Propane: A heavy gas stored under pressure and burned to produce heat.

Radiant Heat: Warmth transmitted to a colder body by the direct contact of infrared rays. See “convected heat.”

Will Call: For Roach customers not on Automatic Delivery, a delivery option where the customer calls to schedule a fuel delivery.

Zoning: A method of regulating temperatures by using a dedicated thermostat and a system of valves and hydraulic heating devices for each area of a home.
