Q: The boiler in my house is leaking and the company send someone to try to fix it. The boiler was working before but now its worse than it was before, and the technician will not put it back the way he found it. He says he's afraid we will sue the company. What should I do?
Well if they refuse then sue.
Q: Want to know the practice of the boiler room vent wells
3.0.3 (3) underground, semi-underground, basement and semi-basement boiler room, is strictly prohibited the use of liquefied petroleum gas or relative density greater than or equal to 0.75 gas fuel.
Q: I was looking to replace my current 30 year old boiler and water heater and some suggested the Navien Combi CH-240 boiler/water heater. It seems like I would save a lot of money making a switch to this. Anyone know anything about these? I have 2 zones in my house, would it be capable of heating both at the same time?
Hello. Boilers like forced air furnaces have to be sized correctly. To do so get the manufacturers recommended specs for the area that you are trying to heat. I.e. length of the radiator runs. Good luck
Q: The water pressure in my Potterton combi-boiler seems to fluctuate wildly. In the morning when it is cold, the pressure is usually around 0.2 bar. I open the valve to manually increase the pressure above 0.5 bar (recommended minimum). When the boiler fires up and the water temperature increases, the pressure slowly rises to around 3 bar (recommended maximum 2.5 bar). I initially assumed it was down to the expansion of trapped air, but I have bled every radiator and they all seem to be fine.I'm guessing the safety valve is opening when the pressure gets too high, which is why it is low again the next morning, but I have no idea why there would be such a big difference in pressure between when it is hot and when it is cold.Any ideas gratefully received.
Peter W is spot on,the expansion vessel on the boiler will either be burst or more likely be needing recharged with air.
Q: I have a Greenstar 12i system Worcester boiler. A few minutes ago the system pressure gauge dropped all the way to red 0 and I need to get it back to at least green 2. I was shown how to adjust it: the boiler comes with a key which you stick into a hole in the bottom of the boiler. Your supposed to push it up this hole and turn it, and it should bring the gauge up. However when I do it nothing is happening. I have spent a good 40 minutes trying to push and turn this key and the gauge isnt adjusting, its very worrying. What am i doing wrong? Should I switch the heating on for a bit and try when its warmed up?
you don't need to adjust the pressure gauge, you need to top up the central heating circuit by adding cold water from the mains. If you look carefully, you should find a filler loop connected to the boiler (flexible hose leading from the cold water system to another pipe close to the boiler with a valve on it). Over time, water in the central heating system may leak out or be vented off for various reasons, and you need to top it up. You do this by opening the valve, which lets water into the system. Do this with the system cold and stop when you hit between 1.5 and 2 bar on the pressure gauge. Don't go poking around trying to adjust anything on the actual boiler. You just might kill us all.
Q: During recent maintenance, I was informed that my boiler furnace was leaking and creating a dangerous situation. The heating company with which I usually do business has been hemming and hawing about getting me a new boiler. I've called them several times but have been given the run around or they have not returned my calls. I tried contacting other heating companies, but they have not returned my calls or tell me since I am not their regular customer, they can't help me (which sounds like a lot of bull to me). The weather is getting colder and I'm a older woman living alone. What should I do?
Simple ring someone else up who does want your money.
Q: What is the meaning of moderate temperature "?
With the rapid development of the power industry, power station thermocouple dedicated thermocouple, thermal resistance of the increasing demand.
Q: Boiler annual inspection standards how much mpa to test, the country which law has this requirement?
Steam boiler safety technical supervision procedures
Q: Marcet boiler
Since this is a lab type boiler intended for students to do thermodynamic experiements, any air trapped in the boiler will effect the results of their experiments. The presence of air will not cause the boiler to over pressure and explode. Air is compressible and less likely to over pressure the boiler than one completely full of water. The boiler is protected by a safety relief valve so the likely hood of an explosion is extremely small,
Q: working on a fourth class power engineering ticket here, so how can u use DP to tell water level
The links below will give you further information on the use of differential pressure to tell a level.
