Flood Damaged Boiler Information

Subject: Flood Damaged Boilers

floodedbasement2The unfortunate situation and questions relating to flooded boilers and heating
equipment arises whenever major flooding occurs.  Our customer service
and technical service representatives are often asked what should be done with a
flood damaged boiler.
It should be noted that flooded boilers present a number of
potentially very serious safety issues including, but not limited to, the following items:
1) Floodwater may enter a boiler and soften the insulation that surrounds
the combustion chamber, causing it to collapse into the chamber.
This causes a very serious safety issue, and under no circumstances
should any boiler be operated in this condition.
2) The silt and contaminants potentially contained in flood
water can be deposited inside boiler controls and safety limits
affecting their accuracy and ability to operate. This also can be a very
serious safety issue and under no circumstances should any boiler be
operated in this condition
3) Floodwater can cause unseen damage to the boiler that may
cause a safety issue or failure months or even years after the incident.
Even components that appear to be unaffected may have sustained
Boilers that are subject to floodwaters or other damage as a result of natural
disaster are not covered by manufactures offering limited warranties for residential
boilers.  Replacing only some affected components in a flooded boiler leaves much to risk, in
addition to being an expensive and difficult procedure  As a result, All Boiler Manufactures strongly
recommends that any boiler that has been exposed to flood water be removed and replaced with a new boiler.
Do not operate your boiler if any components have been fully or partially
submerged in water until the boiler has been inspected and all affected
components or the boiler are replaced by a qualified heating contractor.
Please feel free to contact your Boiler Company representative with any
additional questions that you may have regarding this issue.  Also when replacing a
boiler, consider upgrading to a high efficiency, for fuel savings and “wall hung boilers”  can be mounted high off the floor, where a future flood won’t reach it.

We can handle any oil fired boiler job from a small 3 section residential boiler to 11 sections commercial oil fired boilers in high rise apartment buildings, we have the expertise you need.

Don’t let the numbers on the side of your current old boilers fool you.

It’s most likely far less efficient than you think-

An oil-fired boiler that’s more than 15-20 years old can be functioning perfectly but only working at 65% efficiency or less.  This means that only 65% of the heat from the oil you paid for gets to your house.   This happens because over time the inner chambers of the boiler get corroded with thick residue from the oil fired exhaust and when the walls of boiler’s heat chamber get coated, heat has a much harder time exchanging from the hot exhaust air, to the water filled cast iron sections of the boiler.    This happens to all oil fired boilers as they age.   It doesn’t matter what your oil man does.  The burner could be operating much more efficiently but we’re talking about 3 things.

In reality we have 3 things going on inside an oil fired boiler that effects it’s efficiency.  The burners age- size & efficiency,  the combustion ratio/ exhaust efficiency, and the heat transfer process from the exhaust gas to the boiler itself,  but it’s impossible to know exactly how dirty a boiler is within it, so we can’t really ever get a 100% acute efficiency number on aged oil fired boilers and almost all homeowners thin their heating systems are much more efficient than they really are because the numbers on the service card are misleading by not taking the “dirty factor” even into account.

The fact is when you have an old, oil fired boiler, even with yearly cleaning, much of your heat gets wasted and passed through the boiler and right out the chimney.     The nice thing is, even if your stuck with oil, the industry has done much much better in just the last few years and you are definitely have the opportunity to going to save some money with a new modern boiler.

A boilers job is the catch as much heat from the exhaust gas as possible and transfer that heat into the boiler’s water filled chambers.   Modern boilers called “Triple Pass” have a design that forces the exhausts are the heat exchange surface 3 times before it goes out and up the chimney, where old boilers had very simple designs where the hit literally just straight out from the burner straight out to the chimney.

This process gets less and less efficient as the equipment ages and the inside of it gets more and more dirt.

Newer replacement oil-fired boilers are available that operate above 85% efficiency, and every years they decrease to some degree, even with proper cleaning.

This means if we’re upgrading an oil fired boiler 20+ years old it’s very possible we can lower your oil bills by 20%, 30%, or even 40% by upgrading to new, clean, more modern, higher efficiency equipment available today.   In some cases your home or building may require a smaller boiler than you currently have, saving you even more money.  We always size up the boiler from the ground up to make sure we’re selecting the correct size base on Heat Loss calculations.

We can evaluate your current heating system and provide a free quote on a super-efficient system that you will love.

Important boiler replacement information for homeowners.

When purchasing an gas, propane, or oil fired fired boiler, the most important aspect is getting the correct size, measured by BTU input & output.   The number of BTU’s is, the total numeric amount of “British Thermal Units” (amount of gas) required to heat your home and the amount of BUT’s needs for to create the hot water you use domestically (if using a indirect water heater tied into the boiler for your domestic hot water.)   This total BTU number is based on the worse case, “coldest,” period of the year.   As well as accounting for how much heat is lost, naturally through the windows, the garage,  roof, etc.   This process of figuring out how many BTU’s you’re home or commercial building requires  is called a “Heat Loss”.  The total amount of footage of baseboard, or number & size of the radiators, thickness of outer walls, size & type of windows throughout the home or building area ll required when figure out the exact calculation.

Do Not make a costly mistake by assuming that you need the same exact size boiler as you have now.   In many cases old cast iron boilers installed 20+ years ago were all over sized because the equipment itself and the heating fuel were much less than today.    Builders and engineers had the attitude that “bigger is better,” but when when heating equipment only has to be able to handle the coldest weeks of the winter season you don’t want the equipment over seized at all.   Even a system over sized by as little as  10,000 BTU’s will lead to hundreds to thousands of dollars on wasted fuel over the boilers service life, especially if your burning heating oil.

In this current world of high oil prices and due to the fact that the entire oil energy market is extremely fragile to rate chances, every home and building on heating oil should have a through analyzes of to make sure you getting the properly sized equipment for your home of buildings needs.

Lastly, you can save some money if you’re able to down size  to a smaller less expensive boiler.

Give us a call for a professional “Heat Loss” of your home or commercial structure today.



Energy savings with new boilers. 

You must consider the fuel consumption and how that may affect your budget along with the environment.   The Energy Star logo is an indicator of the efficiency of the boilers,  if the product is 85% efficient or more it’s a good product and about as best you can do for the environment with oil fired boilers and you’ll likely save some money from your oil expense.

Not all plumbers are the equal!   Would you believe that many plumbers don’t even take the time to check if a smaller boiler could be used in order to save thousands upon thousand of dollars over it’s service life?!?   Sad but true in most cases.

Let our professionals figure out the exact amount of BTU’s your home requires/ the CORRECT size boiler your  need!
