Q:I know there's definitely air in it because I can hear water running inside the pipes and sometime making bubble or gurling sound when the boiler is running. It's a 2 zones. I did try to bleed it until I see clear and hot water come out. But I don't if I did it right. Any help is greatly appreciated.
Bleeding your system is dependent how your system was designed and installed. There should be valves to release air at the tops of older, cast iron radiators. Most newer systems have automatic air release valves mounted near the boiler itself. Before bleeding the system, make sure it's properly pressurized. For example, my boiler requires 12 to 14 psi in the system when it's cold. If I lose that pressure I'll hear water running as if there's air in the system due to cavitation, whether there's actually air in the system or not. If your system pressure is correct, you can flush any hot water heating system by opening the water feedline fully (ensuring you bypass any pressure reducing valve), and connecting a hose to a drain bib on the boiler's plumbing. Open the drain bib fully and let the water flow through the system for several minutes. The high velocity of the water should push any air out of the system - even if there are no air bleed valves installed anywhere on the system. Good luck with it!
Q:A small home water heater (for heating) in a two story home what is the normal psi that it should have. I have a closed system running at about 15 psi and the pumps make noise. If I jack the psi up to 30 the noise goes away. What is the cause of this? I am thinking 15 psi is normal. I am thinking maybe the pump is going bad????
15 to 20 lbs. i would say is normal,during real cold weather the system will run alot more and the pressure will rise a little.
Q:What kind of boiler?
Horizontal pot-type boiler is the largest number of industrial boilers. At present, the largest production from the original 4t / h (a small amount of 6t / h) to the development of 40t / h pot-type boiler can be produced.
Q:What will happen if my boiler pressure is below 12 psi?
You haven't said the make and type of boiler. But I assume it's a combi. If it is you either omitted the decimal point or got the format wrong as combis display in bar not psi. So, most combis should be set at 1.0 bar or just above in the COLD state. If it drops to less than about 0.5 bar the boiler will not fire for safety reasons. When the boiler runs, the pressure shown will rise considerably. This is quite normal. Hope this helps.
Q:What documents do you need to use for boiler use?
1, boiler product certification and quality certificates and other safety-related factory technical information is complete;
Q:In my BASEMENT Apartment Where my living room is the boiler is enclosed in a room That is Made Up of Wood And Mesh, Since The Boiler is not completely enclosed by itself in a room, Would the boiler Harm the Baby if the crib was about 10 feet away? The Boiler is new and Well Maintained .My grandparents just installed it about 6 months ago and he get's it checked up on regularly.
Boilers can explode. They are under extreme pressure. If there is anywhere else to put the baby you should move him/her. You should at some point completely enclose it so they don't find it and get hurt.
Q:My water runs hot then turns cold on my combi boiler, what can i do, help please.
If the boiler is sufficient for heating but doesn't produce enough hot water, ask your plumber about adding a separate hot water holding tank, which uses a small amount of fuel, usually gas or electric, to hold a large amount of water ready for those long winter showers.
Q:We just had our boiler looked at and it was determined that we needed a new aquastat. We had that replaced and it worked for about a week. Well now the boiler once again shuts off before the house gets any heat. any idea what could be the issue?
USA Unfortunately, that is like asking Why doesn't my car start? There are a hundred reasons. The aquastat maintains the temperature of the water only in the boiler, not the temp of the house. It acts the same as a thermostat in a water heater - it keeps the water hot in the water heater. If the boiler is heating up, but the house is not getting warm, for some reason the circulation system is not working. Have the system checked to make sure the circulator pumps, or zone valves, or both, are working properly from the thermostats.
Q:Does anyone know of any reputable companies in London that do commercial boiler repairs? I am looking for commenters that have had good experiences. Thanks so much. Any help would be appreciated.
It is quite often a nationwide service. The guys at Manchester Plumbing Heating know their stuff about industrial boiler servicing and it is easy to recommend them
Q:Everything was working fine until last night when my Natural gas Burnham Series 2 boiler gave up. Lost heat and hot water. HVAC guy says I need to replace 4 zone valves and thermostats. Asking for $1250. According to him, my White Rodgers zone valve is sending some voltage back which killed the control head on the furnace. Is it a reasonable price for this job? And is it a possible cause?
I wish I knew what you were asking
