Getting the Most Out of Your Commercial Condensing Boiler

Know Your Boiler's Controller. I used Boiler #1 as my example because it had the out-of-the box settings that offered the most potential savings. Of note, though, is that this boiler has three pre-set reset curves, the most aggressive of which has a maximum HWST of only 120° F and puts the boiler in condensing mode of the time.

Preventing Overheated Boiler Incidents - Northeast Gas

• Hot water boilers risk over-pressurization when there is a failure of the pressure relief valve and at least one other control. • Hot water heating boilers are connected to closed piping systems with potential to build up excessive pressure when water temperatures rise without control beyond the safe operating range (250 degrees).

The Quest for Maximum Boiler-System Efficiency | HPAC

Precisely matching water flow to boiler firing rate dramatically improves system efficiency by preventing system short-cycling. When a boiler is firing and pumps are operating at a fixed rate, a reduction in heat load (caused, for example, by warmer-than-design outdoor temperatures) leads to the system satisfying the call for heat quickly.

Furnaces and Boilers | Department of Energy

Furnaces and boilers that are not sealed-combustion units draw heated air into the unit for combustion and then send that air up the chimney, wasting the energy that was used to heat the air. Sealed-combustion units avoid that problem and also pose no risk of introducing dangerous combustion gases into your house.

What is the safe pressure for a hot-water-heating system?

A member of the Wall community asks this question: What is the "safe" operating pressure in PSI for a hot-water boiler heating system, and what is the "safe" range in terms of temperature for boiler operation? One member responds: The highest pressure the boiler should ever see is stamped on the boiler tag - Usually 30- or 50-psi.

Boilers (industrial) Information | Engineering360

Industrial boilers are closed vessels that use a fuel source or electricity to heat water or generate steam for industrial heating and humidification applications. The basic concept of a boiler involves a heat source (furnace) and a heat exchanger (pipes or tubes) or heat transfer medium which allows water to be heated above its boiling point.

How to Calculate Boiler Heat Input Rate | Sciencing

Divide this heat gain by the length of time for which the boiler runs, measured in second. For example, if the boiler runs for 1,800 seconds, dividing 12,558,000 by 1,800 gives 6,977, or a little under 7,000. This is the heat input rate, measured in joules per second, or Watts.

PEX Radiant Heat FAQ's. PEX Piping questions? Radiant

High ceilings and "lots of windows" are one of the main reasons why radiant heat is chosen as a building heating system. Since hot air rises, in a forced air heating system all of the nice, usable heat is first sent to the ceiling. This may be anywhere from 10 to 20 feet up.

Maximizing Small-Boiler Efficiency | HPAC Engineering

With this control strategy, boiler temperature is lowered to compensate for the reduced heat requirement present at higher loads. Outdoor-air reset has been around for as long as the modern space-heating boiler and is an integral part of all modern controls for condensing boilers.

Firetube Boilers - The National Board of Boiler and

Scotch boilers may be two-pass, three-pass, or four-pass depending upon the arrangement of baffles and tubes. Four passes are generally recognized as the practical maximum when balancing economic heat transfer and condensation induced corrosion. Each pass through the boiler transfers heat from the products of combustion to the water in the boiler.

Boiler Ratings Explained - Heating Help

This isn't about heat loss. This is about heating a LOT of metal. So . . . is the boiler a cold-start boiler (which means you have metal to heat every time it starts), or is the boiler operating on outdoor reset (where there would be less of a temperature rise each time). All of this changes depending on how cold it is outside, of course.
