How to isolate a baseboard heater circuit, drain, purge?

1

I am renovating a kitchen and in the process have a need to remove a baseboard heater from a wall that will now occupy cabinets. The removal is straightforward and will take 10 minutes tops. However I of course will need to drain the line of water prior to doing so. Being from Texas, baseboard heating is new to me. I believe I have the overall concept but want to be sure so that I do not damage my system or cause future problems or hazards.

The first image is a part of the overall system. I have circled what I believe are the main components I need to worry about. Correct me if I am wrong at any point.

In pink is the power shut of for the furnace. I would need to shut this off prior to starting any work?

In green is the supply lines to the heating system (details below).

Yellow are control valves that send the water to each circuit (details below).

Blue are the return lines of each circuit (details below).

I believe that circuits 1...

IF THE BASEBOARDS HAVE INDIVIDUAL COIN VENTS ON THEM, RAISE THE SYSTEM PRESSURE WITHIN 5# OF THE RELIEF VALVE SETTING ( 30# TYP. FOR RESIDENTIAL, SINGLE STORY) , PUT ONE ZONE AT A TIME INTO A CALL FOR HEAT AND CRACK THE COIN VENT SLIGHTLY TO ALLOW TRAPPED AIR TO EXIT. IF NO COIN VENTS ARE AVAILABLE ON THE CONVECTORS AND IF THE INSTALLATION WAS PIPED PROPERLY, YOU WILL ISOLATE EACH ZONE BY CLOSING THE VALVES THAT SERVE IT, ATTACH A SHORT HOSE TO THE ZONES BOILER DRAIN, MAINTAIN SYSTEM PRESSURE AS NOTED ABOVE, PLACE OPEN END OF HOSE IN A BUCKET AND PURGE AIR BY OPERATING DRAIN VALVE TILL ONLY H20 (NO AIR) COMES OUT. CONTINUE AS NOTED FOR EACH ADDITIONAL ZONE. lc

Thanks for the feedback!...

In this video, This Old House plumbing and heating expert Richard Trethewey silences a rattling metal heating unit.

Steps:
1. Turn off the heating system, then drain water from the hot-water baseboard pipes in one heating zone.
2. Remove the front covers from the baseboard heaters.
3. At the midway point along the baseboard, clean the upper copper pipe with emery cloth. Then, use a close-quarter tubing cutter to cut a 1-inch-long section from the upper pipe.
4. With aviation snips, cut away four or five aluminum fins from the heating element on the lower copper pipe.
5. Now use the tubing cutter to cut a 1-inch-long section from the lower pipe.
6. Solder the ends of the pipes back together with couplings, effectively shortening each pipe by 1 inch.
7. When you can't shorten the pipes, install flexible copper connectors. Start by cleaning and cutting the pipes, then solder a connector between the pipe ends.
8. Install plastic carriers...

Baseboard heaters, or hot-water home heating systems, quietly provide relatively evenly distributed heat throughout a building. Water is heated in a boiler usually fired by propane, natural gas or oil. A pump circulates the heated water as steam to baseboards located near the floor of exterior perimeter walls throughout the building. Sludge accumulates within the pipes, so they require annual flushing for optimal efficiency of the heating system.

Turn down the house thermostat to a low setting. Turn off the electrical power supply to the boiler. Some boilers have a simple on/off switch; others are turned off at the electrical breaker or fuse panel. Wait two hours before proceeding to allow the scalding hot water in the system to cool off.

Identify the water inlet pipe that connects the boiler to the house water supply pipes. Locate the valve on the supply pipe and turn it to the off position by rotating it clockwise. Locate the system drain valve, called a boiler...

Hot water heating systems need a little maintenance, like venting the radiators and draining the boiler, to keep things running efficiently. Gravity and hot water furnaces are not often installed in new homes today, but similar systems with the old cast-iron radiators throughout the house were fixtures in homes built around 1900, and some of them are still working. Clanking, popping, and gurgling as they swing into action whenever the thermostat detects room temperatures dropping, they provide a relatively steady flow of heat without the drafts you get in forced-air furnaces.

Hot water systems are closed, meaning that the water constantly circulates through the pipes and into the boiler. Newer units have many zones with two water pipes linked to each zone: one circulating heated water to the rooms and the other returning the much cooler water back to the boiler to get reheated. In the older one-pipe series systems, hot water flowed from room to room, and then back again to...

Here we explain how to remove un-wanted, air from noisy or air-bound hot water heating system pipes, radiators, convectors, and baseboards using the automatic water feed valve on a heating boiler.

If a hot water heating system develops too much air in the piping you may hear bubbling or gurgling in the heating pipes when the heating system is operating, or worse, so much air may be in the heating piping, radiators, or baseboards that heat may simply not circulate at all.

If necessary there are additional methods used to remove air from air-bound hot water heating systems using two different service procedures to force air out of airbound pipes in a hot water heating system.

What is the proper method for bleeding air from hot water systems,, should the system be circulating or off?? I havent tried anything because ive heard different things for my type of system.

The pipes are very noisy with bubbling and gurgling sounds and the constant water faucet sounds in them. Im not sure how to bleed them, so here is how the system is piped now.

There are i believe 2 zones. Out of the boiler the piping goes to a Bell&Gosset Flow control valve-----Then an Air purger/expansion tank----- TEE to separate upstairs and downstairs radiators ----- back to thier respective purge valves then TEE back to another Tee for a manual Freshwater makeup---- valve then to the circulator pump.

There are no bleeds at the radiators, and i am unsure how exaclty the "purge valves" work. The boiler pressure is around 15 psi when the boiler is up to temp. and drops a few psi as it cools.

Any help would be appreciated.
Thanks, and Happy...

Baseboard heaters are often found in older homes because installing them is often simpler than installing the extensive ductwork that other systems require. If you want to install Baseboard Heater in your home, you may want to consider installing it yourself. If you have some experience working with electricity this should be an easy job.

How to calculate the baseboard heaters size?

To calculate the electric baseboard heaters size, as measured in Watts, is to find the room’s square footage and multiply that figure by 10. Homes with little or no insulation should have its square footage multiplied by 12.5. To calculate the square footage, multiply the room’s width by its length.

How to install the baseboard heater?

First, open the baseboard heaters electrical cover plate. A plate is located on each side. Choose the side that the wire will...

Heat traps are made to completely isolate the heat inside of a water heater so that it stays inside of the tank. The two pipes that connect to a water heater, both the cold inlet pipe and the hot outlet pipe, allow the heat to back up inside of them when the water heater is not in use. You can determine whether this is occurring by feeling the pipes where they enter the water heater. They will be slightly warmer than the piping that is several feet away. Heat traps eliminate this wasted heat, making for a more efficient and money-saving water heater.

Turn off the power to the water heater on the breaker panel. Verify that the heater is off with a noncontact circuit tester. Turn the gas valve off if this is a gas-fired heater, and also turn off the main water supply that feeds the water heater.

Drain about 2 gallons of water out of the water heater with a bucket. Be careful during this process because the water will be hot. Turn on the household faucets to purge the...

Answer:

The 006-B2 does not make the hot water. It is used to recirculate the hot water around the house, but the water must be hot in the hot water heater. Open a hot water faucet and feel the pipe coming out of the hot water tank to see if it is hot. If it isn\'t, the heating element in your tank might have failed or the circuit breaker has tripped.

If the hot water heater is OK, you need to check the pump. Is there a timer on the pump or is it connected directly to run all the time? If there is a switch nearby, put the blade of a screwdriver to the casing and the handle to your ear. Turn off the pump and listen for a change in sound. Turn the switch on again and listen to a change in sound. If you hear the motor coast down and speed up, the pump motor is OK but the impeller might have dissolved. The hot domestic water in some areas has dissolved some impellers. We have changed over to a different plastic to solve this problem.

If the motor is cold, you either...
