Types of Boilers | HVAC Heating and Cooling

There are many different types of boilers in the boiler room today in a variety of heating applications. There are two main categories of boilers among the different boilers and those two categories are steam boilers and hot water boilers. Either of those categories can be fueled by oil, gas, or electric (although electric is […]

Hot Water Boiler Expansion Tanks – HVAC Hydronics

Hot Water Boiler Expansion Tanks – HVAC Hydronics Hot Water Boiler Expansion Tanks – There are two types of expansion tanks used on hot water boiler systems. The steel expansion tank and the bladder type expansion tank. These expansion tanks are used to provide a cushion for the expansion of water when it is heated. Without […]

Air Handler Components 3 | HVAC Air Handling

Air Handler Components: Hot Water Coil Heat Air Handler Components – Hot water coils inside of air handler units combine a boiler system or a special capacity hot water heater and forced air to provide forced-air heating. The concept is simple and used a lot in commercial and some in residential. Commercial systems almost exclusively […]

Boiler Pipe Insulation – Energy Efficiency

Boiler Pipe Insulation Richard, I have lots of my boiler pipe under the house in a crawl space and some in the basement and none of this pipe is insulated. I just bought the house last year and this past winter my gas bill was crazy high. Can I increase efficiency by insulating these pipes […]

Hot Water Boiler Piping Zone Valves

Hot Water Boiler Piping Zone Valves Boiler piping zone valves are used for zoning hot water systems where multiple zones are needed. Hot water system zoning can also reduce energy cost because hot water heat zones which are not needed can be shut down thereby reducing boiler run time to provide hot water heat for […]

Aquastat Temperature Control | Boiler Components

Aquastat Temperature Control | Boiler Components The boiler aquastat controls the temperature of the water inside the boiler jacket. The boiler aquastat is a device to a boiler like a thermostat is to an air conditioner, heat pump, or gas/oil furnace. The boiler aquastat controls the temperature inside the boiler just as the thermostat controls […]

Boiler Maintenance | HVAC Heating

Boiler Maintenance Almost as if by rote many maintenance departments begin their annual maintenance in late summer to get ready for the cooler weather. Does your department understand how important the code is or do they take all this for granted? Do they understand that if an accident were to occur all these maintenance procedures […]

Boiler Pressure Relief Valve | Boiler Safety

Boiler Pressure Relief Valve The boiler pressure relief valve is a safety valve designed to relieved an excessive build up of pressure inside the boiler. The is a pressure vessel designed to handle a safe amount of pressure. If the pressure were to build up beyond the safety limitations as set forth by the design […]

Trane Chilled Water Systems – Multi-Zone Air Conditioning Systems

This Trane HVAC chiller serves four different apartments. Chilled water systems offer a great way for multi-zone air conditioning. From small apartment buildings to large commercial buildings chilled water systems can serve multi-zone air conditioning systems. From one air conditioning zone to hundred the only limitation is the size of the chiller. If the air […]

Watts Backflow Preventers | Water Safety

Watts Backflow Preventers | Water Safety Backflow preventers are necessary on water loops where the water is used in a hydronic loop that heats or cools the water through a boiler or chiller system. This Watts backflow preventer is installed on a large boiler system that heat thousands of gallons of water. The hydronic loops […]
