Quick Answer: For a typical residential propane furnace and water heater, I usually look for a low-pressure second-stage regulator or an integral two-stage regulator that supplies about 11 inches water column (11″ w.c.) to the building gas system and has enough BTU capacity for both appliances operating at the same time. For example, a 100,000

Quick Answer: To calculate the total BTU load for a propane regulator, I add the BTU/hr input rating of every propane appliance that the regulator may have to supply at the same time. For example, if a furnace is rated at 100,000 BTU/hr, a tankless water heater at 199,000 BTU/hr, a range at 65,000 BTU/hr,

Quick Answer: Fisher, RegO, and Marshall Excelsior (MEC) all make serious propane regulators for residential, commercial, and specialty LP-gas systems. “RV-style regulator” is different because it describes a compact regulator category—often an integral two-stage or automatic-changeover design—rather than one brand. If I am sizing a permanent house, generator, furnace, or high-BTU system, I compare actual
