FAQ

my boiler is leacking water from the bottom. Every time I fill it up with water. I have a oil burning steam boiler.

Your heat exchanger is cracked or rusted. Before replacing your furnace you should consider trying a boiler stop leak.

How did the explosion of the boiler cause

In the case of boilers, combustible materials refer to natural gas, gas, liquefied petroleum gas, oil mist and pulverized coal. There are explosion in the hearth, blasting and blasting system.

Okay, so British Railways had these Standard Locomotives, and I am confused! Were the BR1 Boilers used on The Standard 6, 7, and 9F Classes? How does it work (the boiler types to Standard locomotives)? I am confused, if anybody can tell me, God bless you and thanks?

The British Railways class 7 (Britannia class) and class 6 (Clan class) express locomotives both had the boiler designed for the class 7. The class 9f boilers were of two types. Ten of the class had Franco-Crosti boilers while the remainder had boilers unique to the class 9, but were a development of the R A Riddles wartime 2-10-0 'Austerity' locomotives. The O V Bulleid 'Merchant Navy' class had welded steel boilers to Mr Bulleid's specification, but were supplied by the North British Locomotive Company of Glasgow who probably had a lot of input into the detail design as the Southern Railway (UK) had no experience of welded pressure vessels. Over their lifetime the boilers have received numerous repairs and number 21C11, 'General Steam Navigation' when I saw it last year standing in an open field near Ashford in Kent was devoid of boiler cladding. The firebox outer wrapper features rivetted lap joints. With regard to drawings of the Merchant Navy Class locomotives, I think that R J Roche may have published a general arrangement drawing in 4mm scale. You may be able to get a copy on Ebay or from Amazon. Front and side elevations were published in the July 1956 issue of the Model Railway News. You may be able to obtain a used back copy. Finally it is worth getting in touch with the library of the Stevenson Locomotive Society. Hope this helps. Edit: Whoops, apologies, I spelt Stephenson wrong

does any one know why?

Shut off the electrical switch from your heating unit then open the cover to your boiler check under the boiler if all the tubing where the fire goes is set properly on the slot in the back because if one of that tube was pitch down? that will cause to blow the pilot light every time the flame on the tube was shut off.Good luck....

I used to have a double boiler but it broke years ago. Kids went on tour of a chocolate factory and came home with bags of huge chunks. They want to melt it down into molds they bought and dip pretzels and strawberries. I tried just melting in microwave but it is getting burned around the edges and tastes horrible.Can anyone suggest a different method for melting chocolate if I don't have a double boiler and don't want to use the microwave?

The best solution to soften chocolate without a double boiler is to use a sauce pan with some water in in after which put your chocolate into a glass bowl on high of the sauce pan, your possess homemade double boiler. That you may additionally use a metal bowl or yet another sauce pan, simply so your chocolate is suspended above the sizzling water. I've executed this commonly and it works first-rate, you simply get somewhat steamier than an actual double boiler and also you ought to watch out that not one of the water gets into your chocolate. This is the excellent means, when you consider that melting chocolate within the microwave interferes with its tempering and will not be as fine. Have enjoyable!

had to wait 2 wks for new bladder. We asked if the radiators should be flushed but the engineer said you don't flush or put inhibitor in these. The engineer fixed it but still it wasn't quite right. He came back and said we needed a new pressure relief valve. Five minutes after he left we had to call him back as the boiler cut out, this happed 3 times more! We asked if we could get a manual for the boiler but he said that manuals are not given anymore because corgi doesn't want owners to try and fix them.Still it wasn't right. He came back and said we needed a new radiator in the boiler, he came back an The hot water is only on for about 4 seconds then it goes cold. This has been going on since november. Now my husband has put cleaner in the rads and is going to try and fix it, mentioning something about a 3 way valve. It seems to me that yes we needed a new bladder but I think we just needed the system cleaned in the first place.Anyone got any helpful advice please?

By bladder do you mean hot water diaphragm. It is not true that Corgi do not want boiler manuals given out. It is part of the regulations that a boiler manual is left with the boiler on installation. You might be able to get hold of a copy from Halstead or whoever owns them now or download a copy off the internet. However what is true is that you shouldn't be repairing them yourself. I have a feeling that these boilers can go to lock-out because the venturi is dirty and also for lots of other reasons as well so don't waste your money havoing a go at different cures. To diagnose blocked heat exchanger you could put temperature sensors on flow and return. To diagnose venturi problem another method is used. You need an experienced combi boiler engineer really not Joe cowboy.

how much is the average price to replace for a new one.. nothing else just a plain boiler???

a lot of variables here,,but to answer your question,,an average new boiler cost around $5000-$7000 installed,,depending on size and difficulty of installation....more than that if a larger home with a very large boiler,over 300,000 btu.......dan

How does one size a boiler for a house?

USA Scott has the right answer. It is called a heat loss calculation. You calculate the amount of heat your house will lose, then you install a boiler that will replace that amount of heat. Heat loss is figured one room at a time. Information needed is the size of the room, height of the ceiling, type of wall construction, what R value of insulation, how many and what size doors and windows. This is done for each room, then added up for the whole house.
