The only universal term is input MBH and the various efficiencies. My intention is to give you a cheat sheet to be referenced when confusion sets in. It was wrong, very wrong. I must admit, I did it for a while.

It had been a few years since I graduated trade school and now I was being taught these CYA rules of the thumb. Back in the day, The Institute of Boiler and Radiator Manufacturers put their collective heads together and gathered results from testing hydronic systems and components. They did it in the laboratory and a six-room residence they built at the University of Illinois. Lots of good things and people come from that state. They can be defined as the rate at which the boiler transfers heat to the system water, assuming the heat loss through the jacket is wasted.

The common name for this assumption is the pick-up allowance. Of course, any degree of pipe insulation is going to alter that assumption or negate it altogether.

How much does it cost to generate electricity with different types of power plants? What are the major factors affecting natural gas prices? Which states consume and produce the most natural gas? How much natural gas is consumed in the United States? This is one of the reasons why it is important to do an accurate room by room heat loss estimate and use the proper boiler output rating for a particular type of installation.

Something else that is not taken into consideration when choosing the correct boiler size is zoning. When zoning a home we reduce the required load on the boiler, for example if we have a home with four zones fairly even in size and the total load is Mbh what are the chances that all four zones call at once.

It is very reasonable to assume some diversity in the operation of this home and I would be very comfortable eliminating the smallest zone from the total building heat load and use the output rating that suits the type of installation for my boiler selection where the boiler is in the heated space. There are controls system on the market today that will monitor and control the zone diversity to make sure adequate heat is provided to all zones.
