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

Tube tube to achieve heat transfer, fire tube boiler structure is simple, water and steam volume, the adaptability of the load changes, the requirements of water quality than the water pipe boiler, and more for small enterprises in the production process and life heating.

Q:Please try your best to help.... I have an error on the screen of the Aquasmart 7600 (Sensor Lockout Err)I have run out of oil a few times which required me to bleed and restart the burner....I am sure this may have been the reason for the issue but I still need to fix it.The Primary Control is a Genisys 7505 if I remember correctly..... 1) I have powered it down and back on and that hasn't worked2) I have tried holding the ENTER/Reset button in on the Aqua and that isn't allowing for a restart eitherThe water level is not lowPlease help me asap. Thank you very much!

The 2 in 1 sensor detects water temperature and water level. The Error indicates that either the sensor has failed or has a loose connection. The Aquasmart control is usually mounted over the sensor well, but sometimes the sensor is mounted a litlle ways distant, somewhere on the boiler water jacket. The cable the comes out of the sensor well seperates into a green ground wire, and a multiconductor cable with a RJ (phone jack) plug on it. Check that the ground wire and clamp are tight. Unplug the RJ jack and plug it back in. Push the cable into the well firmly to make sure the sensor is bottomed out in the well. This is all you can do. The sensor should only be replaced by a qualified boiler Tech. Inproper installation can cause a boiler explosion under some conditions.

Q:What kind of boiler

Traditionally, the boiler is larger than 100t / h for the large-scale boiler, evaporation of 20 ~ 100t / h of the boiler for medium-sized boilers, evaporation less than 20t / h boiler for small boilers.

Q:We have bleed EVERY radiator in the house and most of the upstairs rads wont heat up. And i have looked over the furnace a hundred times and i can not figure out how to add water. Have even searched online and can not find ANYTHING to help! The serial # is 06C3-2003 if this may help!!

Your boiler should have a make up water line that feeds automatically. Look for a water line going into the boiler. There may be a shut-off valve that has been closed. You should only have to bleed the uppermost radiator to get all of the air out of the system. Is your pump working correctly?

Q:on my bolier it says if over 2 call engineer but it is going on 3

If the relief valve doesn't work, it can explode.

Q:What is the depreciation period of the boiler?

(2) aircraft, trains, ships, machinery, machinery and other production equipment for 10 years;

Q:I'm considering switching over to a copper boiler. I've heard all kinds of arguments about alzzheeimmersss. They don't link aluminum to cases of increased risk or do they? No real proof..but the fact that it even comes up worries me.

The short time the water is in contact with the boiler doesn't allow that much time for aluminum to dissolve, but if any is too much for you, then you should find an alternative. I'm not convinced copper is any better. There is also copper toxicity, and if the copper is alloyed, it often contains other metals that may not be good for you either. Aluminum is prevalent in diets, and as far as I know, no corelation has been made between Alzheimer's occurrence and areas with naturally high aluminum in the soil. That to me would/should be easily demonstrated. I did read that if you use highly purified water, like distilled or reverse osmosis, that these purified waters are more mineral hungry and will tend to dissolve even copper pipes, so pure water may be more likely to dissolve nasties it comes in contact with. Sorry, I'm no real help.

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

What you have happening is called delayed ignition. It is usually caused by dirty burners or burner orifices. Have the boiler cleaned and serviced. It should be serviced at least annually anyway.

Q:I have a 120k BTU Weil Mclain Gold hydronic boiler, with tankless domestic coil installed, about 84 AFUE - I think a model SGO something, guessing it's between 8 and 12 years old, one of the pale yellow units. It works but we're converting to gas. Is there a market for a used oil boiler in Central NJ, and how much would you guess it could sell for?Thanks.

The thing is, most people who need a boiler hire someone to install it because it is a pretty hard-core job for the average do-it-your-selfer. Since they are putting a lot of money into the job for labor, they usually get a brand new unit (rather than risk getting a used one that could fail at any time and probably not have any warrantee). Also, a lot of the tradesmen don't like to put in used equipment as, it is hard to predict how much life it has left, fittings 'n things are often rusted solid makes the job take longer and, if something busts/goes wrong, it never ends well. The person who would be interested in it would probably be someone who would do the work themselves, and, if they are doing it themselves, it is probably because they don't have a lot of money. If it was a hot air furnace, somebody might buy it for a workshop/camp (because they don't have to worry about heating pipes freezing when not in use). Where I live, you would be lucky if you can get somebody to take it for free for the scrap value.
