removing steam heating can be risky business

Therefore, the information in it may no longer be up to date.
Also, between the ceiling beams in the basement, there is a hot water tank that doesn\'t seem to be connected to anything;
There is a galvanized cover at one end of the tank, covered in the water or out of the water
I\'m not sure which one it is.
The other end is connected to a pile of galvanized pipes that seem redundant and unnecessary, and doesn\'t seem to be connected to the \"new\" water system at all.
My question is: is it OK to remove the excess tank and all the pipes that we thought were originally used to maintain the original heating system?
We are eagerly awaiting your reply and will send you more information if needed. —Glen Smith, e-mail ANSWER —
In order to answer the most dangerous part of your question first, before consulting a licensed heating contractor familiar with the hot water heating system, you must not remove the old water tank or any associated pipes.
The hot water and steam heating system is not modified or repaired by inexperienced domestic handyman.
The hot water heating system you describe is relatively simple in concept, but there are many complex controls and safety features installed that may be difficult to understand.
This heating system consists of a series of pipes, filled with hot water, cycled throughout the home, and dissipated heat from the large warm radiators in each room. The \"Weil-
In fact, the McLain furnace is a natural gas.
With the help of the above circulating pump, heat the combustion boiler that passes through the water of the system.
By comparing the boiler with a large sealed kettle heated by a natural gas flame, the boiler can be simplified, and the natural gas flame discharges excess combustion products outdoors.
Because the system is mainly sealed, the water expands when heated, and may become steam or steam if it is not controlled.
If this happens in a fully sealed system, the consequences can be catastrophic.
All we need to do is think of a lid blowing from a pot of boiling water to imagine the consequences.
For this reason, there are several control mechanisms on the hot water pipe to allow the hot water to expand.
In addition, the safety valve is installed, and if the hot water exceeds a certain temperature or pressure, it will drain some hot water.
These controls can generate more uniform heat throughout the system and prevent explosions.
The \"hot water tank\" is actually an expansion tank that allows the system water to expand when heated, minimizing the sudden change in pressure during boiler combustion.
It is an important part of any system and will cause several problems if deleted.
There seems to be no purpose for the supply and distribution pipeline attached to this tank, but there may be temperature/pressure release (TPR)
Valves, drains or other key components connected.
The only time this old tank can be removed is if it is replaced by a more modern tank with a bladder installed for better performance.
If the water tank is in the water, the old water tank may install a drain pipe and valve near the bottom to discharge the excess water.
This is a common situation that can be remedied during regular service.
Annual service for boilers and heating systems is critical for appropriate performance and efficiency.
I recommend a full evaluation before use to ensure that all correct control and safety equipment is installed and in working condition.
Usually, in the old hot water heating system with poor maintenance, there is excess air in the radiator, water accumulation in the expansion tank, rust and water leakage in the pipe fittings, and other deterioration is found.
Summer is a good time to evaluate and repair as the heat has been turned off and the system can easily drain and repair if needed.
