Q:How does a home owner know that thier boiler needs to be replaced ? Boiler is 19 yrs old, and had leaked. ?
steam boilers take alot of abuse from the heating and cooling...especially if you dont use any kind of conditioner in your water...20 years isn't too long for a boiler to run as long as you take care of it...
Q:Boiler burner principle
Oil nozzles are mainly pressure atomization and two fluid atomization.
Q:Why recirculation line required in boiler feed pump?
Further to a previous answer. Most boiler feed water pumps are multistage centrifugals. These pumps have a minimum flow requirement that must be maintained to prevent imbalance to the rotor that can lead to thrust problems and damage to the pump. The minimum flow bypass is designed to deal with this problem.
Q:Is this a boiler room?
Well, I love these things - I would get calls from companies that were not selling anything - an obvious lie right off - how do you make money if they are not selling anything? This sounds much more than just a gut judgment - nothing seems right abt this place as you describe it - - If it looks like fish and smells like fish.. It sounds like a miserable way to spend your time - you know, thats what life is - - how you spend your time - - I know things are tough out there... do something constructive and you will feel good all day.. good luck -
Q:Can you put a central heating combi boiler in a bedroom?
The boiler takes the air it needs from the air outside via the flue, so you have no worries about it sucking the oxygen out of the room. The exhaust gases also go out via the flue. --- What are you talking about? You think the air will go two ways through a flue? I have never seen such a thing in my 25 years of repair. LOL. Double wall venting is for heat purposes and won't provide the needed fresh air. I have seen one type of sealed gas wall furnace that had a double vent but that is the only one. No, for code in this country they REQUIRE open venting to the outside both above and below the unit to provide fresh air and exhaust any fumes. And I wouldn't want to live with the noise of the thing either.
Q:Which Industrial Boiler Model is Better?
The operation of the two boilers is the same. As to boiler efficiency it is s matter of boiler design, surface area, air control and and extra devices such as air preheaters or feed water heaters.
Q:how do i adjust pressure on ravenheat boiler?
Your pressure setting is ok at that level but only when the boiler is cold. If it is this level when hot then it is too low. Look for a small back tap like handle on the £water in pipe. If theres not one then look for a small round valve with a slot on it. There should be one. Increase the pressure by turning this as it allows water into the boiler. Just make sure you do it gradually and do not increase it any large amount and make sure it is turned back to the off position when done. I would still advise you allow a qualified person to do this just in case. Anyway, if this doesn't help then you definitely should consult a CORGI Engineer.
Q:How does a boiler room work?
Well, `boiler room' can mean several different things. Assuming that you just mean a room with a boiler, and want to know how a boiler works, that's easy enough ... In a boiler a liquid is heated and maybe vaporized. Usually the liquid is water. Once heated, the water or steam is used to heat the rest of the building, but it can be used for other things as well. I could go into a lot more detail, but the wikipedia pages below cover the issue pretty well. (And I've included pages for other type of boiler rooms, in case you're asking about one of the other types.)
Q:how do boilers use convection currents to get water around a house?
If you are speaking of boilers that heat the the older style radiators without using a pump I can try and explain. They were set up with large pipes that often sloped downward toward the boiler. The way water flowed was that the hot water would rise up toward the radiators and the colder water would just return by gravity back to the boiler to continue the cycle. The same way warm air rises and colder air falls only water is the vehicle.
Q:About what can I expect to pay to replace a hot water gas boiler ?
Nothing, if you make a jw angry.
