Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value ) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.

Since natural gas had twice the heating value of manufactured gas, the company took the bold step to convert its system to natural gas and build pipelines throughout the state. Natural gas was soon found throughout the country, and demand for the fuel was rapidly growing. To meet customer demand, the company began storing gas in large holding ...
The Slant-Six is the popular name for a Chrysler inline-6 internal combustion engine with an overhead valve reverse-flow cylinder head and cylinder bank inclined at a 30-degree angle from vertical.

The defendants have limited time to respond, depending on the State or Federal rules. A defendant's failure to answer a complaint can result in a default judgment in favor of the petitioner.
