Air-source heat pumps comprise the fastest-growing segment of the residential HVAC market. If electricity is the only fuel source available, an electric heat pump is a more efficient option than an electric furnace. The equipment moves heat rather than generating it from a combustible fuel source. This allows for incredibly efficient performance, especially when the temperature is mild outside. Heat pumps also operate in reverse, providing central air conditioning in the summer.

The Boiler and Elevator Safety Law is intended to provide for the safe operation and use of boilers, pressure vessels, pressure systems, amusement rides, and elevators and kindred equipment in the state of Hawaii and is administered through the Boiler & Elevator Inspection Branch of HIOSH. The Branch develops standards and enforces through compliance inspections and investigations. Permits to operate are issued regarding any boiler, pressure vessel, pressure system, amusement ride, or elevator and kindred equipment if found to be safe in accordance with these standards. In addition, Branch staff reviews and approves plans for new installation, repairs, or modification of equipment covered by the law. If you own or manage a building and need to install, repair, alter or relocate boiler, pressure vessel, and pressure system or to install, construct, alter, or modernize any elevator or kindred equipment, forms for permits are available below.
The third most-efficient heating system for homes is residential boilers. Boilers are less common in homes than heat pumps or furnaces. However, a boiler can still be a good option for home heating. They work by producing hot water, which is then circulated through pipes and radiators in your home.
While your business may not need all commercial coverage lines, it is a good idea to have a basic knowledge of the types of insurance coverage available. As your business changes and expands you will have the necessary knowledge to purchase insurance coverage as new exposures arise. The following commercial lines of insurance cover broad areas of exposure common to most business operations:
Boiler and machinery insurance can add an important layer of coverage to an insurance policy. Boiler and machinery insurance is currently marketed under such names as "systems protector," "systems breakdown," and "machinery breakdown" insurance. Boiler and machinery insurance covers business property, other property losses, and legal fees (if any) that may result from the malfunction of boilers and machinery. Boiler coverage includes covering the costs of inspection and often maintenance of boilers. Machinery coverage can include many different types of machines used in retail, office and manufacturing settings. Machinery coverage also includes major machinery systems common to most commercial buildings, such as heating, ventilating and air conditioning systems. Since most commercial property policies exclude losses from boilers and machinery, it is important to be aware of any exposure your business may have and discuss it with your broker-agent.
Our expertise in coal milling, firing systems, and boiler arrangements for all types of coal and other fuels helps maximize carbon burnout. This field experience, combined with our extensive laboratory expertise, is built into our design standards to ensure we offer high-performing, reliable boilers designed for industrial power plants. We also use state-of-the-art modelling and analytics to define optimal furnace arrangements. In everything we do, we ensure that our boilers are right-sized, optimized for performance, flexible, and cost effective.
Our pulverized coal (PC) boilers generate steam power for large-scale global power projects with up to 1,350 MW electrical output for coal units at pressures and temperatures that enable net plant efficiencies of up to 50%.Our two-pass and tower boilers can reach up to 330 bar/650 C/670 C in both single and double reheat configuration.In the two-pass boiler configuration, radiant pendant surfaces are located above the furnace, and convective surfaces are arranged horizontally in the second pass, enabling reduced height of the furnace and simple element support structure. The two-pass configuration is available with both spiral and vertical wall design. The boiler tower configuration has been developed mainly for high-moisture lignite, eliminating the change in direction of gas flow and reducing erosion potential for more difficult-to-burn fuels. It offers specialized firing systems to burn all types of lignite. Tower boiler technology is integrated with an advanced beater wheel mill, providing efficient operation and maintenance with high cycling flexibility. For HFO, two-pass and tower configurations are available up to 1,000 MW in single reheat configuration with 270 bar/565 C/585 C.
Typical boiler pressure on a residential ("low pressure") steam heating boiler (shown below) will be very low, usually under 1 psi. Larger and commercial steam boilers might operate at much higher pressures.
On a residential heating boiler the automatic water-feeder/pressure reducing valve that automatically provides makeup water to the heating boiler if pressure drops below 12 psi. So 12 psi is the typical "cold" pressure for residential boilers.
Because residential steam boilers, also usually "low pressure steam boilers" operate around the 0.2 to 0.5 psi range, the pressure reading you'll see on a typical steam boiler will be quite close to the zero mark.
Initial testing and annual monitoring of the heat transfer fluid in condensing boilers with aluminium or stainless steel heat exchangers is highly recommended. Maintenance of a slightly alkaline (pH 8 to 9) liquid with anti-corrosion and buffering agents reduces corrosion of the aluminium heat exchanger. Some professionals believe that the condensate produced on the combustion side of the heat exchanger may corrode an aluminium heat exchanger and shorten boiler life. Statistical evidence is not yet available since condensing boilers with aluminium heat exchangers have not been in use long enough.
The condensate expelled from a condensing boiler is acidic, with a pH between 3 and 4. Condensing boilers require a drainpipe for the condensate produced during operation. This consists of a short length of polymer pipe with a vapour trap to prevent exhaust gases from being expelled into the building. The acidic nature of the condensate may be corrosive to cast iron plumbing, waste pipes and concrete floors but poses no health risk to occupants. A neutralizer, typically consisting of a plastic container filled with marble or limestone aggregate or "chips" (alkaline) can be installed to raise the pH to acceptable levels. If a gravity drain is not available, then a small condensate pump must also be installed to lift it to a proper drain.
The primary and secondary heat exchangers are constructed of materials that will withstand this acidity, typically aluminum or stainless steel. Since the final exhaust from a condensing boiler has a lower temperature than the exhaust from an atmospheric boiler 38 C (100 F) vs. 204 C (400 F) a mechanical fan is always required to expel it, with the additional benefit of allowing the use of low-temperature exhaust piping (typically PVC in domestic applications) without insulation or conventional chimney requirements. Indeed, the use of conventional masonry chimney, or metal flue is specifically prohibited due to the corrosive nature of the flue products, with the notable exception of specially rated stainless steel and aluminum in certain models. The preferred/common vent material for most condensing boilers available in North America is PVC, followed by ABS and CPVC. Polymer venting allows for the added benefit of flexibility of installation location including sidewall venting saving unnecessary penetrations of the roof. 041b061a72
