Short cycling occurs when a boiler powers down before being able to complete a typical boiler cycle and is called upon to satisfy a second call for heat, in quick succession. A typical boiler cycle consists of firing, post purge, idle period, pre-purge and then back to firing. Boiler short cycling can be seen in two critical areas; mechanical and economic.
In this blog, we discuss how this affects the boiler and how we can mitigate short cycling and losses incurred from it.
Eventually, all commercial heating systems need to be replaced – and whether you replace one unit, or five, it will require a significant investment in time and money. In upgrading your system with the latest technology can offer in condensing equipment, high system efficiency, building management and connectivity, the cost to retrofit your boiler room can escalate quickly.
Just like we would debate over sports, music, or politics, engineers have long held strong opinions about piping arrangements for hydronic heating systems. Which is better: Primary-Secondary or Variable Primary? They each have their benefits, but most boiler manufacturers tend to side with Primary-Secondary. Wouldn’t it be nice to have a different choice?
Placing system efficiency at the forefront of commercial boiler acquisition continues to be a trend in the heating and water heating industry. Manufacturers are racing ahead to push the limits of technology by offering aggressive turndown capabilities approaching, and even exceeding 20:1, at the detriment of system efficiency.
Stainless steel has increased in popularity over time due to its success in a number of different environments and applications. Stainless steel commercial boilers have proven to be reliable and efficient in both retrofit projects and new installations.
If you are curious to learn why stainless steel has gained popularity in the heating industry, Patterson-Kelley has compiled a list for you that includes the top three benefits of owning a stainless steel commercial boiler.
The commercial heating industry has faced an ongoing debate on the benefits of stainless steel heat exchangers versus aluminum heat exchangers. The process of choosing a new boiler has become confusing for both building owners and engineers.
Like changing the oil of your Ferrari F60 every 3,000 miles, all heating equipment, both boilers and water heaters, require annual maintenance. No matter the life expectancy of a heating system, ‘WEAR & TEAR’ will interfere with the performance of your heating equipment.
The technological innovation of boiler systems has drastically enhanced how users interact with their boilers. The industry continues to improve safety and efficiency standards to fit the game changing environment. Today, users seek features that influence the return on their investment. These notable features include increased energy efficiency, great zone controls and low operational costs; all of which can be achieved by selecting the right boiler control technology.
Thermal efficiency is simply the chemical energy added to the boiler divided by the energy added to the boiler water. As more energy is transferred from the hot gas into the boiler water, the thermal efficiency increases and the temperature of the hot gas decreases.
Water treatment is essential to ensure peak boiler performance and operational efficiency. Up to 15% of thermal loss occurring within the first two years of boiler operation can be attributed to poor water quality. Untreated water inside a boiler can cause the following: overheating, failure to produce hot water, and shortened life expectancy of the system.
