We describe the actual procedure for adding anti-freeze to the system, and we answer questions about how much anti-freeze to add and what type of anti-freeze to use. This article also discusses the risk of poisoning the building water supply piping if you use the wrong type of boiler antifreeze, and we explain the effects of using anti-freeze in a heating system on the thermal conductivity of water and on building heating system efficiency and operating cost.
Heating boiler antifreeze, usually a non-toxic polypropylene glycol anti-freeze and water mixture is installed in hot water heating boilers and plumbing systems to reduce the risk of expensive freeze damage to the heating system piping and of course to avoid costly water or even mold contamination that occurs when an unattended building suffers burst heating piping and leaks.
Even if a heating system is in good and reliable working order, loss of electrical power or running out of fuel means loss of heat that in freezing weather means burst pipes and water damage to the building. Reader Question : How do you add anti freeze to you boiler and what kind do you use? Don, some help on winterizing a boiler as well as a whole building is at Winterize- Heat Off Procedure. The basic procedure is to use a pony pump a transfer pump to add antifreeze buy at your local heating supplier to the water mix in the boiler until our test gauge shows that we've got enough antifreeze in the system to protect down to at least a bit below the lowest expected temperature.
Typically one washer hose connects to a zone drain or to a drain on the hot water riser out of the boiler our photo at above left. The output side of the transfer pump is connected to one of these hoses; the other hose drains into a bucket from which we can use a hygrometer or refractometer to measure the antifreeze concentration in the heating system's water now water-antifreeze mix.
The pump pushes antifreeze into the system from the bucket; keeping the drain end of the second hose below the level of antifreeze in the bucket avoids introducing air into the system and thus avoids having to bleed that air out. Exact transfer pump hookup points and step by step procedures : Since the transfer pump hose connections are the same those used when forcing water through a hydronic system to correct an airbound heating system problem, you can see another example of this transfer pump to boiler hook-up.
Watch out : if you are going to perform this boiler anti-freeze addition task frequently buy a good quality transfer pump If you buy a "cheap" transfer pump it may not last long when handling antifreeze mixture. Watch out : for building water damage and loss coverage insurance issues. If you are winterizing a building by adding glycol based antifreeze you might have an insurance coverage issue with your insurance company and thus you might not be covered should a loss occur.
Usually heating system antifreeze products use propylene glycol. As we explain here, there are some good reasons for using a non-toxic anti-freeze in heating boilers. Watch out : Be sure you are buying the right antifreeze product: an anti-freeze intended for use in heating boilers, not automobiles or trucks - the chemicals are different, and as we explained above, automotive antifreeze ethylene glycol is toxic poisonous.
Not only is the care and handling of toxic chemicals more demanding, on some heating systems there can be a risk of accidentally introducing toxic antifreeze into the home water supply system.
The applications for propylene glycol anti-freeze such as that used in hot water heating systems include:. Should the heating boiler include a tankless coil used for making domestic hot water, and should there be a simultaneous loss of water pressure inside the tankless coil and a tankless coil perforation or leak, then the contents of the anti-freeze treated boiler can leak backwards into the building water supply piping.
While this combination number algorithm solver events is unlikely, it is possible, and it has happened. Watch out : some boiler antifreeze products are not suitable for use in heating systems or plumbing systems that use galvanized steel piping.
Check with the manufacturer and check your system's heating piping. There is no simple right answer to the anti-freeze quantity question, despite some DIY articles saying you need 10 gallons of antifreeze for a typical sq. The answer depends on the total volume of water that is in the hot water heating system; the volume of baseboards, radiators, pipes, pumps, expansion tank, and the boiler itself.
But nevertheless, it is very easy to know when you have added enough anti-freeze to a heating boiler, as we explain here. What a heating service tech does is use an inexpensive anti-freeze hydrometer or refractometer designed to measure propylene glycol PG concentration to actually measure the antifreeze concentration in the antifreeze-water mix in the boiler. When the gauge indicates that freeze protection is down to the required temperature, you've added enough antifreeze.BOILER ANTI-FREEZE ADDED FOR WINTER SEASON
Record the test results freeze protection temperature and date that the antifreeze was added on to the heating boiler's service tag. The amount or volume of antifreeze you need to add to the boiler to reach the desired freeze-protection temperature will also depend on the concentration of the anti-freeze product itself. Use a hydrometer or refractometer to test the water-anti-freeze mixture in your heating system. The hydrometer, if you've bought the right type, will read the freeze-protection temperature right off a scale within the instrument.
Watch out : not all hydrometers accurately measure both types of antifreeze chemicals automotive system antifreeze, i.
Make sure that your antifreeze concentration measurement is made using a propylene glycol PG refractometer or hydrometer or using a hydrometer that can according to its scale and instructions measure both types of anti-freeze chemical concentrations. There are some variations in the absolute level of freeze protection given by various products due to the inclusion of special additives and by variations among manufacturer's formula.

But even with all these features, this antifreeze would end up being a no-buy for me.Aqua-Hot RV boiler systems offer some serious advantages to that of their less expensive and more common RV hot-water heater counterparts.
Aqua-Hot systems offer unlimited hot water, often run off of your RVs primary fuel tank diesel models and also heat an RV much more evenly than propane furnaces. They offer multi-zone support, do not as severely affect internal humidity levels in your RV and can even be used as engine block heaters to start your engine in colder weather. We have had our challenges with our Aqua-Hot system yet for the most part we are very happy with the purchase and are glad we sprung for an RV that had this feature.
Stay tuned and make sure to subscribe for more information on that topic coming shortly but in the meantime lets do some routine maintenance! With all that functionality, the systems do require additional maintenance to keep them running optimally. Today we are going to review the process of changing our Aqua-Hot system antifreeze.
There are two types of anti-freeze fluid recommended by Aqua-Hot. Most dealerships use Century brand antifreeze which is green in color however most retail establishments and online RV retailers stock Camco which is pink in color. This brown mix fluid will work fine but may make things more difficult to troubleshoot should you have problems down the road. This is because brown fluid looks similar to contaminated fluid that may have been exposed to water contaminants and other undesirables.
It will be harder to identify other system issues since fluid color is one of the indicators of something wrong with your system. We recommend going with the pink Camco fluid as its more readily available and also available in a high-concentration 32oz bottle which is much easier to carry in your RV for quick top off jobs.
That said, if you find your system to be low, it is always better to add fluid then to let the system antifreeze level be low so use your best judgement. You can learn more about the fluids below in the FAQ section link which will bring you to a handy page kept current by the manufacturer. This topic has a lot of discussion around it but in short the frequency in which you should change your fluid is largely dependent on how much you use your system.
Under normal conditions we find that we like to change out our fluids every 24 months to ensure trouble-free operation. Many users report issues with check-valves which are located inside of the Aqua-Hot system and can stick or freeze due to lack of use or poor fluid quality. The propylene glycol fluid has a high viscosity slippery to minimize these issues and as a result we recommend changing the fluid regularly as fluid viscosity can breakdown over time.
There was a detailed article on IRV2 on flushing the Entegra Aqua-Hot system with water first before changing to the pink fluid. There have been several articles on NOT mixing fluid types. It was kind of involved, using a pump to flush each zone with distilled water until it drained out clear, then flushing each zone with the red fluid until it drained out red, then fill the tank and run to burp the system. We had lots of trouble with the Green fluid when Entegras first came out and there has been an effort to convert to the Pink.
I did the annual maintenance after it began to smoke on startup, but have not flushed it yet. Your email address will not be published. Notify me when new comments and replies are added.
