BTU = British Thermal Units: that quantity of heat required to raise one (1) lb. of water one (1) degree on the Fahrenheit scale. MBH = 1,000 BTU/hr. PPH = Pounds of steam per hour. Gross Rating – The full output of a boiler actually available to the heating or process system at the outlet nozzle.

So, for a boiler that produces 210 kW (or 700,000 BTU/h) output for each 300 kW (or 1,000,000 BTU/h) heat-equivalent input, its thermal efficiency is 210/300 = 0.70, or 70%. This means that 30% of the energy is lost to the environment. An electric resistance heater has a thermal efficiency close to 100%.

Heat Exchanger (HX) One boiler that heats water for brewing espresso and hot water/steam – and do allow you to use both functions simultaneously. The water in the boiler is superheated to create steam. ... This design results in two separate temperatures to meet the demands of brewing and steaming at the same time.

The Motor Generator Unit - Heat (usually abbreviated as MGU-H) is a component of a hybrid-electric internal combustion engine. The unit is an evolved component of a turbocharger, where the exhaust gasses (the "heat" part of the name) are used to also generate electricity, and the unit also functions as a motor.

Heat Exchanger (HX) One boiler that heats water for brewing espresso and hot water/steam – and do allow you to use both functions simultaneously. The water in the boiler is superheated to create steam. When a shot of espresso is pulled, that water comes from a coiled HX pipe which sits within the boiler.

But while the equations look the same, they use MMBTU as the units. They do take the extra step to note: MMBtu = 1 million Btu. MBTU commonly means mega or "M" BTU (x10^6) or 1 million BTU. But it sometimes means "M" for mille or Roman numerals M, which is (x10^3) 1 thousand BTU.

A unvented system has a pressure/expansion vessel, which is a vessel with a diaphragm, as above the diaphragm allows for expansion. A system boiler unlike a combi has stored hot water - for larger properties - or where a few taps could be used at a time therefore a combi flow rate wouldn't suffice.

BTU – British Thermal Unit: A BTU is relative to the size of the heat pump unit. The capacity of a heat pump is rated in BTUs, and there are 12,000 BTUs per ton. So, if you have a two-ton heat pump, it has the capacity to produce 24,000 BTUs of heating or cooling.
