Water Central Heating with Boiler Vents

 

Water central heaters provide adequate heating through out a building with the use of pipes to pipe the water to the various parts of the building.

 

The basic way a water central heating system works is that it uses a boiler, radiators and interconnecting piping, in order for heating to circulate the boiler heats the water and then a pump circulates the water through the pipe work and radiators in a circular fashion back to the boiler.

 

There are two main boiler arrangements:

 

• The open vented systems

• And the sealed systems

We will discuss the Open vented systems

 

This works with a hot water cylinder which is used to store domestic hot water. Using natural atmospheric pressure as a feed/expansion tank is open to the air. The feed/expansion tank is usually fitted high above the rest of the system and usually placed in the loft of house. It basically works with a ball valve and when water is lost due to evaporation etc. it is automatically replaced, the tank is designed so that it allows the water stored in the system to expand when it is heated, you need to make sure that the ball valve is set very low so that expanded water does not create an overflow.

 

Water vented from the system up the vent pipe is recovered; you will find that the vent pipe is connected from near to the boiler and is then bent over the tank. Water is fed down from the tank to connect into the boiler system between the boiler and pump sits adjacent to the vent pipe.

Installation of your water central heating with boiler vents it is best to follow manufacturer’s instructions very carefully in order to follow all Safety Codes including the ASME Boiler and Controls Codes, National Fuel Gas Code (NFPA 54/ANSI Z223.1), National Electric Code (NFPA 70), Uniform Codes and other applicable National, State, Local and Servicing Gas Supplier Codes. It is recommended that only qualified personnel do the installation.

 

Choosing a boiler for a specific need is important, consideration must be given to the size of the boiler it must have adequate capacity to handle the maximum hourly load. If installing in a high volume area it is good practice to install a boiler with sufficient capacity to handle future expansion.

 

A boiler requires fresh air for safe operation and must be installed so that there is adequate combustion and ventilation air.

 

Proper Boiler Venting System need to ensure the necessary draft for efficient combustion, and also to develop a positive flow which is adequate to convey all the products of combustion safely to outside atmosphere above the building. The Boiler Vent should preferably be circular and made of metal, proper vent clearance should be provided. Outside vents should be properly insulated in cold climates.

 

A Barometric damper or draft hood should be installed directly onto the Boiler Vent Outlet

 

Please ensure that you follow all manufacturers’ instructions carefully, for both safety and safe installation of your boiler.
