FAQ

Built in the 50's, nameplate is wore out, I do have install manual MN. ou-2650. It apprears to have been manufactered by US Radiator Corporation. Any help is appreciated.

u either have to clock the gas meter or measure the main burner orifice's along with the gas pressure,,this is something that a tech would normally do,,if u are looking to replace the boiler u would have to do a heat loss on the house and that would tell u what size boiler u would need

in which part is hi pressure inside the steam boiler?

The steam itself becomes the pressure

Hi - i don't know if anybody can help me... i am having a nightmare trying to repressurise my boiler. A Vokera Syntesi 25e. My filling valve is permanently connected so i did as my boiler instructions said to increase the boiler pressure and turned the filling loop to the vertically down position. I expected to hear water entering the boiler and the pressure to rise but nothing happened. My central heatign system is working fine - all radiators and warm water nice and hot - so I dont know what the problem can be. My pressure is below 1 bar at the moment so would like to increase it. The filling valve loop reaches from the filling valve (the one with the three normal/off/filling loop positions) along the loop to another tap on the left which has a black knob marked with open/shut in two directions. What is this and am i supposed to do anything with that? Any help would be much appreciated

Boilers run at a low pressure, usually less than 20 lbs psi. Your pressure will vary depending on the water temp during firing or non firing times. Ex: my electric boiler runs as high as 20 psi while it's heating, but drops to less than 5 psi when idle and cool. You might just have to check the pressure when the system is hot and has been circulating for awhile. Another thing to check would be to open a bleeder on a radiator and see if the pressure drops to nothing [water stops coming out]. This would be evidence of a defective fill valve. But if the water continues to come out if the bleeder, you are probably fine. Check when boiler isn't running full bore, to avoid getting burned.

what maintenance needs to be done on a steam boiler furnace for optimal performance?

steam boilers can be very dangerous if you don't have experience with them, get a certified tech,

What are the main differences between water pipe boilers and fire pipe boilers?

Of the heating surface layout is convenient, good heat transfer performance, the structure can be used for large capacity and high parameters of the working conditions, but the water quality and operating level requirements are higher.

Hello, I just got a new eco boiler, and am trying to work out what would be the cheapest way to run it. There is 2 of us in the house and it takes 1 hour to heat the boiler for showers for both and plenty for washing up. The boiler doesn't have any outside insulation but it is 27+ degrees room temp here, so what do you think? 24 hours keeping the heat all day and switching it's self on and off. We really don't need hot water all day long. Or 1 hour a day running constant? Cheers :)

Your boiler will burn more energy running on demand from cold starts, than it will maintaining a consistent temperature throughout the day. Some types sold in the US have a vacation setting that will prevent it from cycling while away, but this option should really only be used if you will be gone for a long time. I'll assume the 27 dg room temperature is Celcius and not Fahrenheit, which doesn't matter too much however your boiler will operate more efficiently if it has an insulating jacket for cold days. If you insulate it the boiler won't have to cycle as often. Not sure about eco-boiler if it's the type that employs a tank or has a coiled heat exchanger, and if so may not require an insulating jacket. These types of boilers are already engineered to be efficient appliances so you'll do yourself a favor by letting it work on it's own and not turning it off while you're away.

I have gas-fired Crown Boiler (c 1991), used in a closed heating system. Steam flows to my radiators, however no cold water returns to the boiler from the radiators. As a result, I have to fill the boiler twice a day, or more.

Something's leaking somewhere. Is this one-pipe or two-pipe steam? If one-pipe, the air vents (usually made by Hoffman) may be letting the steam out. If two-pipe, the there may be a leak in the condensate return piping. Either way, you should get it fixed. When you add water to a boiler, you're introducing more minerals. It's best if it just uses the same water over over.

banking a boiler;putting it on natural draught;steaming a boiler

There is a control panel with every boiler which regulates the amount of fuel (which means regulating the steam), air blower, etc. Also there are mountings and valves and pressure indicators. Its easy.
