Boiler runs but not getting any heat coming out of the radiator


When you have a call for heat from the t-stat, the first thing that happens at your boiler is the circulator turning on. Turn off the stat, let the boiler cool down, and stand by the boiler when someone else turns the stat on. Put your hand on the circulator. If you feel it start to run when the stat is turned on, it's OK.

If it's not the circulator,then it sounds like the system is airbound and must be purged.

If you have actual radiators instead of baseboard, then each radiator must be bled. You can get a radiator key from any good hardware store. It may take a few circuits around the house to chase the air down so bleed each radiator at least twice.

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.

Glowworm boiler making noises


You're probably getting what some call gurgling sounds because there is air in the system. You need to bleed the air out at all bleed ports starting with the lowest in the system and ending with the highest.It won't hurt if you do that process a couple of times. Once all the air is out, you should have a normal convection flow of water through the system. - Good luck!

I have a vaillant ecotec plus 630r1 system boiler, since two weeks ago the central heating part of it is causing problems. Even when i put the heating dial on max most of the rads would not get hot and...


You either have a bad circulating pump or you have air in the system. A little bit of air can completely stop water flow in a boiler system. Your problem is more than likely air though. Each radiator should have an air bleed on it. Turn your boiler completely off. Go to each radiator and open the air bleed. It will be located towards the top of the radiator. After air is bled out, close the air bleed and go to the next one until all have been done. If you have a two story house, start at the lowest level of radiators. When you are finished start the boiler back up and let it run for about 2 to 3 minutes and shut it back down and bleed all the radiators again. If you are making progress and getting more to heat up but not all of them yet, keep repeating process until all of them heat up.

Gas Condensing Boiler High Efficiency Heating



Ultra high efficiency boilers have become one of the best buys in home heating. These high efficiency boilers have changed dramatically from the first pulse boilers that I had the privilege of installing twenty years ago. Today’s condensing boilers are much more reliable and will not shake and rattle the windows of your house like those old beasts did.

If you are looking to purchase or install a new boiler for your new or existing heating system then you need to look a condensing boiler to heat your home with. In the past twenty years the condensing gas boiler has evolved to be a reliable, very efficient way to heat your home.

Radiant heating systems with the right design feature can easily heat your home at temperatures that use just warm water. At these temperatures the water is pulling the exhaust temperature of the boiler to very low points. This gives you extremely efficient boiler operation.
The boilers of today are made to operate continually at temperatures of 100F or less. At these temperatures it is not uncommon to have the combustion analyzer give me readings of 98-99 % efficiency. To get these types of readings and still heat your home the heating system has to be designed to work at these temperatures.

The right condensing gas boiler coupled with the right heat transfer system to get the heat into your home the right way will give you the most efficient heating system possible with today’s technologies.

Do a bit of research and find a heating contractor that knows exactly how to install a condensing boiler with a radiant heating system properly. For your radiant heating system to perform well at these temperatures, your boiler will need to be installed in exactly the right way. There is not a lot of room for error when designing very high efficiency heating systems. To wring every BTU of heat out of the fuel that is being burnt means that you are also on the ragged edge of supplying just enough heat to the building to over come the heat loss of the building at any given time.

Outdoor wood boilers come in many shapes and sizes. For the most part bigger is better for these things. The next thing you need to consider is whether the boiler is open or closed. It does make a difference in the way it gets hooked up. Closed systems can be hooked right up to your existing boiler system in a primary secondary configuration. This means that the wood boiler circulates to two tees in your home system and the home system circulates the water through the home. The two waters mix through the tees.

If your wood boiler is an open system then you need to install a stainless steel flat plate heat exchanger to divide the two waters. The hookup of the heat exchanger is not that hard if you follow the instructions properly. This heat exchanger is very effect in transferring the heat from the wood boiler to the inside heating system. It also keeps the water of the inside system pressurized and isolated.

If you are installing your outdoor furnace to a hot air heating system then you need to buy a coil similar to your car radiator to install in the plenum on the supply side of your existing hot air furnace. To this coil you will hookup the water pipes from the outdoor boiler. The water running through the coil will heat it up so that the air going through from the hot air furnace will be warmed. The water hookup for this style of heat is very simple, but the electrical hookup of the blower, pump, and circulator may not be as simple. You may need someone with a good electrical knowledge to make everything happen in the right sequence.

Outdoor wood boilers can heat your home effectively if they are installed to your existing heating system properly. If they are installed properly you will notice no difference in the heating of your home. It will be warm and comfortable. Make sue that you do your research properly before trying to install your outdoor wood boiler.

Water and radiators dont come on at the same time i have to turn the valvue with screwdriver and then water comes on or turn it again then radiatorscome on please help


I assume this is hotwater heating.  Your problem is air in the line.  You may have something called an airscoop at the boiler...it is attached to a pipe at the top of the boiler and has a radiator vent unit on top.  Purge it and you may fix your issue...or not.
If you don't have one or the problem persists, you'll have to bleed all of the radiators...perhaps several times.  Be sure when you're doing this that you have water in the boiler before and after.  If you fire a dry boiler, this is a problem which will be very expensive.  You should see about 15 PSI or so of pressure indicating on the gauge.  If you see less than 10 or more than 25, you also have a feed valve issue.  These things do get dirty and they do clog.
If your vent valves at the radiators are more than 10 years old, get replacements.  Take a couple of pictures of them and go to the plumbing store.  Turn the water to the boiler off and quickly change each one.  Turn the water back on, bleed again and you will be fine.
