Q:What is the effect of the main steam pressure on the steam turbine?
In the steam turbine operation, the beginning of the steam pressure, steam temperature, the main steam flow and other parameters are equal to the design parameters, this operating conditions known as the design conditions, this time the highest efficiency, it is also known as economic conditions.
Q:Can a leaking cast iron section of a steam boiler be repaired?
yes, and it can be easy if you have a wielding/arc weld machine. if not, then it still can be relatively inexpensive to have it professionally fixed.
Q:What can i do about broken boiler?
There are no schemes that will help you. You need to pay for yourself in this life. My only suggestion is sell the house and move into rented accommodation then boilers and repairs won't be your expenses but the landlord. Unlikely the boiler is beyond repair so simply get it fixed. My charges for replacing a combi boiler are £900 that includes the boiler. Don't get conned by british gas and others who will say it costs £3000 or more to replace a boiler
Q:Detecting Leaking Gas-Fired Condensing combi-boiler?
Personally I wouldn't touch a combi, instead I'd buy a system boiler (condensing) for the heating, and a gas fired water heater for the hot water. When a combi goes duff you usually end up with neither heating or hot water, and a tidy bill for the repair, furthermore the hot water delivery rates of most combi boilers is not too good on multiple hot water outlet homes. So if you're thinking of en suite in the bedrooms give the combi a miss. An unvented cylinder is fine but it is dependant on the heating boiler, at least if the boiler broke down you could use the immersion. From experience I would suggest a boiler by Worcester Bosch (but we all have our favourites) For the hot water I would 100% recommend a Rinnai water heater - this will give hot water non stop all day until you turn off the tap. The big adavantage here is that you are not heating up water to be stored in a cylinder - the Rinnai will only heat water instantly on demand. Make sure the guys confirm to the building regulations and fit thermostatic valves etc - if you need the full info your local council Building Control guy will give you the info on what's required. Generally when a new installation is completed the installer will self certify the work to the local council. If the council guy comes round and sees that some works have not been done he could get awkward. Good Luck

Q:Why is the 'lock out' button on my boiler lit up?
clean the flame sensor . i don't know what type of boiler you have but all have some sort of flame sensor . some are called cad cells or electronic eyes look up info on your specific brand and model . it just sounds like flame is not being proven . routine maintenance could prevent this as any heating and cooling unit needs tune-ups just like your car does. a maintenance plan with a quality hvac service can prevent problems before hand
Q:What experience have you had with Peerless Boilers?
peerless makes a good boiler. weil mclean gold is also another good one.
Q:Why did my boiler stop turning on after I bled my radiator?
Underneath (usually) your boiler there will be a tap that tops up the pressure in your boiler. You need this to be around 1-1.5 bar. And yes bleeding the radiators will cause this problem. You will find that over a period of time the pressure will naturally drop so the clanging was likely the pressure already low. If you can't find the filling point check the boiler manual as sometimes there is one fitted to the boiler
Q:Is Geothermal the better than a boiler?
Geothermal is less expensive over the long term than any other type of heating or cooling. It's efficiency is around 115% versus the best boiler which gets 98%. That is because you are moving, not creating heat. Installed loops in the ground are generally rated to last for the next 50 years with no serious maintenance. Geothermal will work with existing duct work systems. There is no need to circulate water around the house. The liquid going outside is usually treated and contained, not general water. If you will live at your location for the next 5 to 15 years it will pay for itself. The length of time it takes to pay you back depends on what you are replacing. New construction should do so if they possibly can afford to do so regardless of if you will live there for a long time or not. This will significantly raise the value of the house.
