Question about Desa International CBN30T Central Heating System Heater

1 Answer

My new heating system is very noisy. When the system is switched on the the water makes a continual trickling noise as it runs down the pipes from the cylinder above to the boiler below and only stops when it goes off. The Plumber has run out of ideas. What is the answer to stop this water noise?

When using shower basement pipes start clanging and Rattle and make a horrible noise some say it's water hammer some say I need to replace the flap in my toilet bowl any suggestions


Debbie, probably water hammer, but your pipes may not be supported/attached properly. Have a good plumber or a knowledgeable friend take a look to see if pipes hang loosely and can be attached more securely. If pipes are secure and supported properly and noise is still there a water hammer will have to be installed. Check the attached links,instruction and guides they may enable you to cure the noise from pipes on your own. Good luck.

Hot Water Steam Efficiency Plus Comfort


Steam heat is a great warm, wonderful, and absolutely fabulous way to heat your house. Steam heat is almost always created from water in a boiler fueled by gas, oil or electricity. It then passes through pipes and radiators or convectors to heat your home. A steam heating system uses steam that is generated from a boiler. When the water boils, the steam rises through the pipes and into the radiators to heat them. The hot radiators then heat your home.

Steam is a great heat distribution medium because it moves easily through your system and it has an extremely high heat-holding capacity. The heat-holding capacity of steam is much greater than that of water. Steam heating systems often operate at very low pressures and usually under 220°F. Steam heat is usually distributed by either one or two pipe systems. In a case of a one-pipe steam heating system, a single main serves the dual purpose of supplying steam to the heat exchanger and allowing condensate to run back from the radiators also. A two-pipe system has two connections from each heat exchanger or radiator. In this system, steam and condensate flow in separate piping from each other. With a steam system all pipes must be well insulated and you must use pipe insulation rated for steam piping. If the insulation is removed the system will no longer work as designed. Noise and all sorts of problems will come from uninsulated piping.

When you have radiators on upper floors or radiators that are further from the boiler they should be adjusted to release more air to compensate for the increased air volume in the piping due to the distance from the boiler. If you have a valve that is clogged with mineral deposits or stuck shut, no air will be able to get out of the piping. Because of this no steam can enter the radiator, so it doesn't heat up. This will block the movement of steam into the radiator, or cause a very noisy hammering as pressurized steam tries to get through this water "dam".

Steam radiators need to have a valve that allows air to escape at a controlled rate so that the radiator can heat up. Steam heating systems will also lose a little bit of water all the time, so there has to be water makeup so that you do not run your boiler dry. Steam heating systems without an automatic water feeder are not safe. You will risk serious boiler damage should boiler water be lost. If the boiler runs dry it could also explode if water is placed into it while it is hot. There should always be a low water cutoff installed on every steam system. Therefore on a steam boiler the automatic water feeder serves as a safety device also.

It is very important that you find someone that is very familiar with steam heating systems when repairing or installing steam heating. Incorrectly designed, installed, steam systems and condensate piping is a huge problem in today's buildings and facilities. There are not many qualified to design and install properly operating steam heating systems. Incorrect steam piping will always cause costly premature failure of steam equipment such as steam coils, heat exchangers, and control valves. Not to mention the higher cost of operating a system that is not working efficiently.

I hear a knocking noise behind the wall when I use the hot water. What could it be and how do I get rid of it?


I had something similar, but I would call the noise more like 'ticking'. The problem was that hot water would heat up the plumbing vent piping (plastic) for that bathroom and it would expand and then contract (after shutting hot water off). As the pipe 'grew' it would make noise sliding through the opening in the ceiling header. It seems that builders had stuffed loose fiberglass around the pipe there that served to let the pipe move freely. The fiberglass had fallen out and the pipe was rubbing against the wood and making noise. Stuffing new fiberglass in the opening around the pipe fixed it.

Hello my dishwasher just makes a noise when switched on what could it be please sounds like a water problem? thank you


Normally the inlet pipes have a stailess steel mesh to block the dirt from entering your machine, when you tap water and it reached its level then the solinoide is actully closing the water for you, it is posable that that mesh is blocked and the solinoid is making that noise. Close the water supply, remove the pipes on the machine and make sure that mesh is not blocked, if it is open have a look at the fan belt, that can also lead to the noisy problem, if it is not a direct drive

Water will not drain out


Check the drain filter located at the bottom of the wash tub. Clean if clogged. The pump noise could be due to non availability of the washed water continuously due to clog.

Clean the drain filter. Check the final drain output after the pump(hose) for free flow if you have connected it to a drain system.

I have a pin hole in my copper pipe


first of all shut off the water to the area and see if the flow has ceased, if you still have a trickle of water you will not be able to solder the pipe. Any water flow will make the repair impossible. If you can get the water to slow to a trickle you will need to cut the pipe in half and solder a sleeve in its place at the cut. once the pipe is cut you can take a peice of bread, yes bread, and pack the incoming water side and this will stop the flow long enough for repairs to be made. The bread will break down to minute particles after the soldering is done and shouldn't hurt the system at all. If it is impossible to cut the piping at the area there is a pipe patch that you can purchase at most local hardware stores the wont require the water to be shut off however, this is a temporary repair and may start leaking again in the future. Good Luck on your repairs Hope I have helped you some

Pump has started making a loud "slurping" sound when it shuts off, similar to sucking on a straw at the bottom of a glass. Is there a way to adjust this noisy pump?


I'd double check your check valve, located in the discharge pipe, is still working. If the flapper inside has failed the water in that pipe runs back down into the pit and you'll hear 'bubbling' and the air is forced out by the water coming back down...another symptom may be your pump running more often than it used to. If the check valve is of, it sounds like the pump is drawing down closer to the bottom of the pit than before and that is causing you noise...can you adjust the length of the cord that is free to the float? If so, shorten it a little at a time until the noise goes away.

Noisy pipes with hot water baseboard heat


The natural expansion and contraction of the pipes due to the hot and cold water is what makes the pipes sing. I'm not aware of a fix without repiping.
