Rated 5 out of 5 by Inhibited anti freeze Re filled central heating on narrow boat with this product to save on buying both anti freeze and inhibiter separately however as you dilute 75% water this large 5 Ltr will last for a very long time indeed, just need to find a space on the boat to keep it! 21 Jun 2016
Rated 5 out of 5 by Does EXACTLY what it says I've used this product a few times now and it does do "Exactly what it says on the tin"! A great product for the price, especially when you compare it to the 'major' manufacturers. 31 Mar 2016
Rated 4 out of 5 by Excellent value An good price compared to the branded makes for use with my external boiler. For obvious reasons, you will need a few bottles to keep the concentration correct and will wear out overtime. 19 Oct 2015

Hello Ginernewlife,

This is something we are unable to advise upon. For this we would advise that you speak to a suitably qualified tradesperson as all systems are different.

Thank you for using Q&A.

Answer: 
Yes. You need to add it at 25% to get BuildCert level corrosion protection - so that's 1 part inhibited antifreeze to 3 parts water. Count the radiators to estimate the system volume. 10 radiators will be approximately 100L in which case you would need 25L - that's 5 X 5L packs. This will also protect your system to -11C. If you need more frost protection add according to the table on the pack. If you have more or less than 10 radiators adjust in the same ratio - so that's one 5L pack is needed per 2 radiators.

Answer: 
According to BS7593 it's not advisable to mix inhibitors from different manufacturers however we have not encountered incompatibility issues with Sentinel products. The inhibitor in No Nonsense Inhibited Antifreeze is also molybdate based. You need to add a minimum 25% to protect the system and get decent frost protection.

My question is would the sealey ak4122 tester be able to test the concentration of a treated system as this tests propylene glycol. Thanks in advance

Answer: 
The Sealey AK4122 is a hydrometer for testing car antifreeze which uses a different glycol to that used in central heating systems. It gives a colour coded read out that indicates treatment levels. For a 25% solution of central heating antifreeze you would be looking for a Specific Gravity reading of 1.01 at ambient temperature. The best way to use the device successfully is to make up a calibration solution of 1 part inhibited antifreeze to 3 parts water and note the position this gives on the readout. Match this position in your treated system.

I too want to use it in a static caravan but would like to test the concentration when it is installed. I can find testers for Ethylene Glycol based solutions.

Answer: 
No - not ethylene glycol but mono-propylene glycol. The concentration can be tested with a refractometer or hydrometer - a reading of SG 1.01 will indicate a 25% solution which will give BuildCert level corrosion control of metals and frost protection to between minus 11C and minus 15C
