How do I neutralize my boiler condensate?



How do you neutralize condensate?

1) Manually, by cutting a bed of limestone into the floor where the condensing water heater, boiler, etc., is located, and letting the condensate drip into it. 2) Positioning a limestone-filled cartridge inside of the condensing unit to neutralize the water internally.

Do I really need a condensate neutralizer?

Condensate neutralizers are crucial for treating acidic condensate from high-efficiency heating appliances. Without a neutralizer, condensate has the potential to corrode a building’s foundation, floors, and drainage system. Properly installing a neutralizer is fundamental, but only part of the solution.

Is the condensate from boiler toxic?





Is boiler condensate dangerous? Generally speaking, there is nothing dangerous about boiler condensate. Some of the carbon dioxide created during the combustion process dissolves in the condensate, making it slightly acidic.

What makes boiler condensate acidic?

It is hot and when it comes into contact with steel pipes etc. it starts to cool. When the water cools, carbon dioxide (CO2) dissolves within it. At the right pH, it forms carbonic acid that can corrode metal parts and even concrete and plastic.

What is a condensate neutralizer kit?

A condensate neutralizer is a tank or a vessel, which is installed in line with a condensate drain from a condensing boiler, water heater or furnace (before it enters the sewer). It’s filled with media which raises the pH level of the condensate, making it safe to discharge into the sewage or septic system.

Where do you put a condensate neutralizer?

Neutralizer should be installed below all traps and condensate outlets. Neutra-Safe condensate neutralizers should always be mounted with a minimum of ¼” pitch downwards towards the outlet.

Can marble be used as a condensate neutralizer?





Limestone and marble chips are perhaps the most popular media for condensate neutralizers and are quite effective. As long as the design of the neutralizer properly distributes the flow across enough surface area of the media, you should be fine.

How long do acid neutralizers last?

Acid Neutralizers are the most efficient and most economical way to eliminate acid water. They’re easy to size based on the water’s pH and the number of people in your home. And, they’re simple to install, plus only require minimal maintenance every 6 to 18 months.

How corrosive is furnace condensate?

Condensate formed from combustion gas is extremely acidic and therefore very corrosive. It can eat through copper piping in a matter of months and through cast iron drains in just a year or so.

Can boiler condensate go into sink waste pipe?

Yes, a condensate pipe can be routed into a waste pipe. This is best done after the trap on the waste pipe in case of blockages.

Can boiler condensate go into ground?

Under no circumstances should boiler condensate be put straight to ground or down the side of buildings without first being neutralised. We have seen a reasonable number of installations where the condensate outlet drain is released directly down the side of the house or flat.



Can boiler condensate go into septic tank?

Why Boiler Condensate Should Not Enter Your Septic Tank. We’ve already covered this in a little detail above, but it is worth repeating – you should, under no circumstances, let boiler condensate enter your septic tank or waste system. That is, unless, you have a neutraliser. Boiler condensate is notoriously acidic.

What is an acidic condensate neutralizer?

A condensate neutralizer is a reliable, purpose-built solution. It serves as a filtration device for the acidic condensate created during the combustion process in gas-fired, high-efficiency appliances. As the appliance extracts heat from exhaust gases, the vapor in the gases condenses into a liquid condensate.

What is an acid neutralizer?

Acid neutralizers usually use calcite to raise the pH of the water before it enters your household plumbing and wreaks havoc on your pipes. Calcite is crushed white marble media that’s rich in calcium and very high in alkalinity. Acid neutralizer tanks are installed at the water’s point of entry into your home.

Why do you need a condensate trap?

The condensate drain trap in a high-efficiency furnace keeps air from moving in or out of the air handler or coil box during its operation. It is a compulsory component of the furnace drain as it aids in ensuring that your unit functions correctly.

Can marble be used as a condensate neutralizer?

Limestone and marble chips are perhaps the most popular media for condensate neutralizers and are quite effective. As long as the design of the neutralizer properly distributes the flow across enough surface area of the media, you should be fine.



What is a neutralizer?

A neutralizer is a substance or material used in the neutralization of acidic water. It is a common designation for alkaline materials such as calcite (calcium carbonate) or magnesia (magnesium oxide) used in the neutralization of acid waters. Neutralizers help prevent: Acidic well water from creating blue-green stains.

How corrosive is furnace condensate?

Condensate formed from combustion gas is extremely acidic and therefore very corrosive. It can eat through copper piping in a matter of months and through cast iron drains in just a year or so.

Is condensate toxic?

Like all fossil fuels, condensate contains toxicants which are harmful to the environment, animals and humans. It is generally more flammable and explosive than normal crude oil.

Where do you drain the condensate on a boiler?

Where should a boiler condensate pipe go? The HHIC states that: ‘When fitting a new or replacement boiler, the condensate discharge pipe should be connected to an internal ‘gravity discharge point’, such as an internal soil stack, internal kitchen or bathroom waste pipe such as sink, basin, bath or shower waste.
