Q: I have recently experienced my boiler losing pressure. I can reinstate the pressure using the valves underneath but over time it goes again. I have read on other forums that I can isolate the boiler with pressure up for a period of time and this will tell me whether the fault is with the unit or somewhere else in the system. Only problem - no one tells me what this isolating involves! Can anyone advise step by step what i do? Is it as simple as turning the heat and hot water off?Thanks: The only way you can isolate the boiler would be to shut off the supply and return, but there's not typically valves installed in those pipes....and even if there were, it'd be a bit of luck if they sealed well. If your boiler is leaking, you'll usually see that one or more of the burners are badly rusted from water leaking on them. If you take the vent hood off, you can usually see any cracks or rotted parts just by giving it a close inspection. Depending on the boiler, you may have to at least partially remove the jacket as well.. Hope this helps

Q: I am converting from oil to gas and have a gas line already in the house. This includes everything except the boiler, including removal of oil tank and boiler. The basement is easy to work in.: I would say its a pretty good figure. But on the other hand, I would definitely get another number if your in the least bit puzzled by the number at all,

Q: Explain the effect of magnetic scale to the boiler tube?: I think you are talking about the formation of magnetite (Fe3O4). A layer of magnetite is considered to be a protective layer on the tube formed by the corrosion of a small layer of the base metal (tube wall). The layer of magnetite is desirable and is actually a controlled corrosion which degrades the tube at a slow and uniform rate. Boilers are designed for a corrosion allowance and the loss of tube wall thickness due to the magnetite layer is expected. Water chemistry is maintained to protect the magnetite layer to prevent other forms of attack and corrosion. Other forms of scale due to salts form buildup on the tube wall. Any scale buildup causes the temperature difference across the tube wall to increase. If an entire boiler system was scaled up, to maintain the same thermal output, the temperature on the fire side of the tube would have to be increased to maintain the same temp. on the water side of the tube. Eventually, tubes will fail due to the extreme temps.

Q: is there a list of boiler parts i can see?: Go to a website like Weil MacLean (they make boilers) pull up something like a cdi model and I think on their they have all the parts that make up a boiler system like the boiler, circulator pump (that is just above the boiler), the expansion tank that is usually over top of the boiler and a few other things.

Q: What is the problem with the boiler? The fire is burning great but the water temperature isn't going past 70°. Problem just had started day before yesterday. Any advice is welcome: Sounds like a thermostat problem. Loose connection or gunk in the thermostat that is not giving an accurate temperature.

Q: What is the cause of the boiler water alkalinity?: Should be: even row of sewage is not timely will increase the alkalinity, the sewage is too small, should be connected to the maximum should be sufficient to reduce the alkalinity.

Q: Boiler flue system: After the combustion of hot flue gas in the order through the furnace, slag tube bundle, superheater, economizer and air preheater, and then through the dust removal device, remove the fly ash, and finally by the fan to the chimney to the atmosphere

Q: OK, I'm one of those peasants that tossed the tea in the harbor and all that (or least descended from them) and keep noticing the term combi boiler in a lot of questions here.I've concluded that this term refers to a boiler that supplies heating hot water and domestic hot water. Correct?Can anyone explain the mechanics? Does the appliance use a single heat exchanger, recirculating heating water but supplying domestic hot water via a diverter valve and make up water?Or are separate heat exchangers employed, heated by common burner, to feed each plumbing set?Thanks in advance!: you can check a few websites and you will see that there are a few different methods. But all things considered a combiboiler for a house is a waste of money when you consider todays cost cutting alternatives such as the new demand types.

Q: If a boiler (such as in a steam engine) is under pressure, then how is the water level maintained? Surely the water would have to be at an equal pressure to the steam inside the boiler.: Water is added to a boiler FIRST! (Get a lil experience and then it'll be funny!) Seriously though, yes, your boiler feed pump delivers water at a pressure exceeding that of the outlet steam pressure.

Q: Is it possible to convert a combi boiler running off mains gas to bottled propane?: Yes. You need to contact the manufacturer for an L.P.G conversion kit for your make and model of boiler. Some boilers are being made slowly obselete so you may have a bit of difficulty but if its less than 5 years old you should have no bother. A good place to get the conversion kit is HRPC (part of the CENTER branches eg PlumbCenter, BuildCenter, Electrical, Drain, Pipe etc...) they are nation wide. Another good one is PLUMBASE as they have a parts counter. If you have the installation guide then you are laughing, just take that into them and ask for it. Usually its a series of jets to be replaced in the older boilers but if its one of the newer condensing types its often a case of adjusting the inlet pressure on the gas valve and then checking the mixture with a flue gas annalyser! No parts! Conversion kits range hugely from ?25 to ?90 on average. Your engineer must be GAS SAFE (formerly CORGI - see the logo on my profile? Thats what it looks like. Ask to see his card) and will be able to do this quite easily. Converting it over with jets takes about an hour, usually less but it depends on the boiler. Running it off bottled propane really eats it fast so make sure you dont leave it running! Get a good timer and make sure its off! To change the tanks over on a domestic property you need a qualified person to do it - its not the same as changing the bottle over on a caravan or boat. The physical act is - but for legal you need to have it legally tightness tested each time. Check out the legal side by calling Gas Safe, they are very helpfull and dont mind average Joe Public calling at all, in fact they encourage it. But YES is the answer for 99% of cases Good luck and if you want to know more just submit more info and ask away!
