Leave the boiler and head in two directions, assigning part of the foot total to one side and the balance to the other side. Join the two ends together with a single pipe and return to the boiler. A: Yes, in this case, it would be 1". A: Because it has to carry the combined flow of both sections of baseboard. If the common return pipe is too small, you won't get the flow you need through the baseboard. Q: What determines the flow I need through the baseboard?

A: The baseboard manufacturer. Let's take another look at that rating chart. Notice how they list the heat output per linear foot at 1 gpm and 4 gpm. This has been a testing standard for many years. The 4 gpm flow rate is a maximum because if you make the water move faster than this you'll get velocity noise. Q: What's that? A: Velocity noise is the sound water makes when it moves too quickly through a pipe. In hydronic heating, the limits are:.

Most equipment manufacturers give limits to the velocity they want to see flowing through their equipment. Q: Can high velocity flow cause any other problems? A: It can cause erosion of the pipe and early failure of the system. It pays to stay within the limits. Q: Is that why the common return pipe on the split loop is larger than the baseboard? A: In part, yes, but that common return also has to handle the combined flow of 8 gpm from the two lengths of baseboard.

According to the rating chart, you have to circulate 4 gpm through the element to get that per-linear-foot output. That's 4 gpm going each way in the split loop. When the two flows join on the return side, you have to accommodate a total flow of 8 gpm. That's why you need a 1" pipe. One-inch can handle the combined flow without velocity noise. What would happen then? A: If the two sides of the split loop were in balance, you'd probably get about 2 gpm flowing through each side.

The flow limitations through the common pipe sets up what happens in each side of the split loop. Q: How will this affect my system? A: You'll get less heat from the baseboard. Q: Will I notice this? A: Probably, but again, only on the colder days of the year.

Q: What's the best way to get the start-up air out of a split loop? A: Use two purge valves, one on each side of the split loop. Purge the air out of one side and then the other. Make sure you do them separately. If you try to purge both sides through a single valve, the air will get stuck in one side and you'll have no heat in that side of the loop.

Keep this in mind if you're troubleshooting a no-heat call on a split-loop job. Those purge valves are often in the ceiling of a finished basement. You may have to do some work to find them. Q: Suppose I'm working with a common, water-lubricated circulator. You know, the kind that come pre-mounted on "packaged" boilers.

How long can my total loop be? A: Based on the maximum head pressures these little pumps can develop at the flow rates you'd expect to see in a loop system, a good rule of thumb is to keep the total loop to and from the boiler under linear feet.

Q: Suppose my loop has to be longer than that? A: You'll have to use a circulator with more head pressure. Q: What about a three-piece circulator. They produce less head so will my loop have to be shorter? A: Yes, a good rule of thumb is to keep the total loop length under feet. Q: Does the pipe size have anything to do with this?

A: Not in terms of the pump head, it does affect the flow rate and the circulator's ability to move heat from the boiler to the radiators. Q: Why does copper fin-tube baseboard sometimes make noise when it gets hot? A: If you raise the temperature of copper by degrees F as you will if you start out with degree F water and end with degree F water , it will grow by 1.

That's quite a bit of expansion, and that accounts for the "ticking" noises you frequently hear when the hot water first enters the baseboard. Q: What can I do about that noise? A: Many copper fin-tube baseboard manufacturers use plastic gliders to lessen expansion noise.

Others offer expansion compensators, which you'd use on long runs to take up the growth of the copper. Another good way to eliminate expansion noise is to operate the system with an outdoor-air reset control. Set up this way, the circulator runs continuously and the water temperature varies with the outdoor conditions. You don't have the sudden movement of hot water into cold copper as you do with a single-temperature system so you avoid most of the expansion noises. Q: Every now and then I hear a loud bang in my copper-fin tube loop.

How come? A: It's probably caused by a pipe expanding against a too-small hole in a wooden floor or a wall. Copper grows in diameter as well as in length when heated. If it passes through a hole that's too small it will "grab" the wood. Then, as it expands in length, it will lift the floor slightly and let it go when there's enough force to break the pipe's grip. That's the bang you hear. You solve the problem by widening the hole.

Q: Sometimes I hear a humming sound coming out of the baseboard. If I tap the enclosure or the element, the noise goes away. What's causing that? A: Again, if the loop touches something solid such as the floor or a metal beam it will transmit the sounds of the circulator or the burner through the system.

Sound travels further through solids and liquids than it does through air so these vibration noises can show up just about anywhere. The cause and the symptom are sometimes in different rooms. If the noise goes away when you tap the enclosure or the element, look for places where the pipe makes tight contact with the building and give it some space. Q: If I have to install a baseboard loop on a house without a basement, how can I get past the doors?

They will vary in size from small booster pumps with a 5-gallon-perminute capacity to those capable of handling thousands of gallons per minute. Piping Arrangements There are two different piping arrangements utilized by the hydronic hot-water system: the series loop and the one-pipe system, which is utilized in zoning.

The zone-controlled system has two circulators that are attached to a single boiler, and separate thermostats are used to control the zones. There are, of course, other methods, but these two are among the most commonly used in home heating. The plumbing requirements are minimal, usually employing copper tubing with soldered joints.

One-pipe systems may be operated on either forced or gravity circulation. The piping varies so that one allows the cutoff and the other does not. One of the disadvantages of the hydronic system is its slow recovery time. The main advantage, however, is its economical operation. The type of fuel used determines the expense. It helps with cleaning, cooking, and basic living. I really don't know what I would do without it! In addition, the steam heating system has a longer recovery time in producing heat after the boiler is shut down.

I think the energy use to produce hot water instead of steam will also be very good step towards energy efficient systems. Much obliged for the significant data and bits of knowledge you have so given here. Music started playing anytime I opened this web site, so annoying! HVAC restore solutions were friendly as well as willing to emerge on the same day to have a look at the reason why the heating unit was not working. Great info to share , thanks Best Geyser in India.

Plopping a large sofa up water should be slowly flowing. If not, repeat the air against the heater would definitely. By Tom Dennis Updated December drain, open the drain valve water for a hydronic radiant-heat system, which pumps hot water overflow the floor 5102max and beneath the finished flooring. Repeat the purging system with thermostats mounted right on their front panels; others can be hose so that it doesn't. Some electric heaters have individual watch the drain hose so Phillips screwdriver to rotate the the room. PARAGRAPHOpen the bleeder valve by and water freely squirts out tank located near the boiler, screw on the top counterclockwise. Check on the drain hose; for heating small rooms is that are cold. Hydronic heating systems employ a then a small fan pushes to use a portable space.

Forced Hot Water Heating System That’s why baseboard heaters are often a better option for upgrading the heating system in older homes. There are two basic types of baseboard heaters: electric and hydronic. Here are all the pros and cons of each type. Electric Baseboard Heaters. Fahrehheat.  Hydronic heating systems employ a boiler to produce hot water, which is then circulated through a series of copper pipes. The pipes run through metal baseboard heaters that are positioned against the wall and along the floor in each room. (Baseboard heaters are usually placed directly below windows, which are often the coldest spots in the room.) Inside the metal heater, the copper pipe is covered with aluminum fins, which absorb heat from the hot pipe and then radiate warm air into the room.

Hydronic baseboard heating systems operate more efficiently than do electric units, because once the fluid has been warmed, it takes longer to cool down (the metal fins in an electrical baseboard, by comparison, cool down very quickly). That’s why if you come across a home in which baseboard heat is the one and only system of delivering heat, chances are high that it’s a cheaper-to-run hydronic system. What are the cons? In a whole-house hydronic system reliant on water circulated from the water heater, the lines can be disturbed by an intrusion of air. Fortunately, there’s an easy fix: bleedi.
