Q:Please list more than 5 disadvantages of a instant water boiler. THANKS!

Disadvantages of Instant Water Boiler : 1. It’s more costly to install and service compared with forced-air furnaces. 2. It’s more difficult to add central air conditioning, humidifying, and filtering equipment to a home. 3. There is a greater selection of furnaces on the market than boilers. This is especially true at the high-efficiency end of the spectrum. 4. Radiators take up more space in rooms than heating registers. 5. A leak in a hot water system usually means water damage. A leak in a supply or return duct system does no damage. The bottom line is that hot water heating is a good system. Conversion of any heating system is expensive and disruptive.

Q:I recently move and my new apartment have center boiler heater. And I have put them next to the heater. So, I was just wondering is it ok for my birds or not.Also, there are acting well eating drinking and playing..

They should not be next to the boiler, there are many reasons for this. Most health issues. It can make it harder for them on their little lungs, it can cause them to dry out and lose their feathers. And so on. It could take months before seeing the damage, a damage that might be hard to undo. Place them across the room from the boiler instead. They'll live a longer life if you do so.

Note 2: For the boiler operators who apply for a single furnace type (such as organic heat carrier boiler, vertical hand burner, waste heat boiler, oil field steam boiler, etc.), the contents of the assessment can be focused, and in its "special equipment operations

Q:am i doing any damage pressing restart. guarantee just run out. any information would be greatly welcomed. just had it flushed,but no luck.

Worcester Central Heating Boiler

Q:We have lived at our current address for almost three years and the landlords havn't had our boiler serviced once. They ignore phonecalls or just fob us off with excuses when we talk to them. Now our boiler has completely packed in and leaked all over the kitchen. We have no heating or hot water. We also have our 8 month old daughter in the house. They will not answer their phone or respond to our messages. They have been terrible with maintenance in the past and are probably not going to do anything else to the house because they are selling it. What are our rights? I know that it must be illegal to not service the boiler and leave us with no heating???

You are right it is illegal not to service the boiler and they can be prosecuted for it. This situation is a grave concern. The best people to contact are not the CAB like some on here will advise but the Housing Officer based in Environmental Health at your local Council - every Council has a statutory duty to have one. Give them a call - they will come out to see you and have the powers to make the Landlord sort this out, and even prosecute him. You dont deserve this especialluy with a baby. Give Enviromental Health a ring first thing, they are the ones with the powers here. In my experience though bad Landlords like this often issue you with 2 months notice to quit in retaliation, so if I were you I'd have a contingency plan in place just in case.

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.

Multi stage feedwater pumps are used to pressurize the water to a higher pressure than the boiler drum pressure, so the flow can be regulated by a feedwater control valve. These pumps sometimes have 2 parallel water paths along a single shaft, with an inlet stage at each end of the shaft and both high pressure outlets near the center of the shaft, so the shaft seals at the ends of the shaft do not have to deal with the high outlet pressure. This also balances the the axial forces of the water pressure on the two ends of the shaft. It can take hundreds of horse power to drive a large feedwater pump. -- Regards, John Popelish

Q:I need to help my parents to clean out the water of the steam water boiler. I bleed out the dirty water using the lever until the water run clear. I opened the lever for the fresh water to fill up, but I went to do something else and forget to stop it before it reach the mark. There is a black mark on the tube, and I was told by my parent to fill up to that line. Now the tube is completely filled, is there any way I can lower it down the proper level? Is there any danger fill it up all the way? I tried to use the same lever that I drain the dirty water to drain the fresh water, but the water level didn't go down at all. I took out 5-6 buckets already, anything else I can do?

Your boiler should have a drain valve, it will look like an outside garden hose spigot. It will be very low to the floor may have to get a small pail or even a cup to drain into. If you have a spare washing machine hose, that will screw onto the valve.

Q:What is the farmula of measuring Horse Power of a steam boiler by its heating surface?

*Boiler horsepower is used rating a boiler's capacity to deliver steam to a steam engine. The amount of energy needed to produce 34.5 pounds (15.65 kg) of steam, per hour, at a pressure and temperature of 0 Psig (0 bar) and 212 oF (100 oC), with feed water at 0 Psig and 212 oF. One boiler horsepower is about 33,479 Btu per hour (about 9,810 watts, 8430 Kcal/Hr). Boiler horsepower can be determined from the heat transfer area. PBoHP = A / 17 where, PBoHP = boiler horsepower A = heat transfer area (ft^2) *In a water-tube boiler there should be from 10 to 12 square feet of heating surface for one horse-power; in a tubular boiler 14 to 18 square feet of heating surface for one horse-power; in a flue boiler 8 to 12 square feet of heating surface for one horse-power; a plain cylinder boiler should have from 6 to 10 square feet of heating surface for one horse-power; a locomotive boiler should have 12 to 16 square feet of heating surface for one horsepower; a vertical boiler should have from 15 to 20 square feet of heating surface for one horse-power. When considering the heating surface of a boiler, a vertical or upright surface has only one-half the evaporative value of a horizontal surface above the flamet; that is, the sides of a locomotive fire-box are only half as effective per square foot as the flat top of the box. In flues and tubes, the effective surface, measured on the circumference, is 1% times the diameter.

Q:I had a new natural gas boiler installed just over a year ago. It seems to make a slight rattle/ bang sound when it kicks on! what can I do to remedy the problem

By all means clean the burners and make sure that the damper is opening in a timely manner. It also could be a sticking flo check or a zone valve, in all reality you should get a good licensed plumber to check it out. There's way to much that could be wrong with the little bit of info your giving.

Q:I'm having trouble with physics revision and heat transfer. There's a question in the book about whether a boiler should be dark and matt or light and shiny, and I just don't understnad! Can someone explain it to me?

Is the boiler in your book at the focus of a solar collector? If so then dark and matt is good otherwise it really doesn't matter. If it's a wood, straw,dung or fossile fuel boiler then it is effectively surrounded by (or surrounds) a firebox ( if the outside of the firebox is light and shiny then that's great but it has nothing to do with the boiler) the one exception I can see is where you have a fan driven gas boiler where the main heat exchnger is actually inside the boiler and the outer surface of the boiler should be light and shiny to cut down on waste heat radiated from it. So if radiative transfer of heat out of your boiler is a problem then it should be light and shiny but if the boiler works by absorbing the maximum amount of heat by radiation from a source which is much hotter than the boiler surface then black and matt.
