inhibitor

Hi, I've just watched a video online on how to add inhibitor to central heating. I know I've got to turn off both valves at bottom of towel rail first. I did the left hand one easily, but I'm struggling with the right hand one. The one on the left had a cap which came off easily and I then...

We had our house re-plumbed about 9 years ago with a sealed system with solar thermal panels. (We also had new boiler installation 5 years ago). Wanting to re-decorate the main bathroom I was surprised to see on removing the towel rail that the air vent plug at the top was corroded (the sealed...

Evening hive-mind, Yesterday I serviced a 5yr old Ideal combi. When I took the top off the magnaclean, (which was chocka,) I was alarmed to see the system water was the colour & consistency of cream of tomato soup! I didn't need a test kit to realise that there's no inhibitor in the system...

I'm going to attempt some work on my central heating system which will involve partially draining it down, possibly a number of times. I have a small water pump, so in theory I could keep the drained water and pump it back into my system. Then I wouldn't have to worry about replacing the...

Hi All, So I found out the central heating system in my house has a Primatic cylinder so I can’t add inhibitor due to the risk of the water and hot water mixing. I am just fitting some TRV’s and wanted to replace 3 old rads with some new ones whilst the system is drained down. Eventually a...

I am currently studying my level 2/3 in plumbing and heating systems and thought Id ask the professionals. Is there a solid formula for calculating how much inhibitor to use on a heating system within different sized properties?

Hi All My boiler after about 7 years has startd ratting like a bag of bolts/kettle boleing when CH is on. It has NEVER had any additives or a magnetic cleaner ! I have heard of build u of limescale etc causing this and LOADS of even (even registered plumbers) of using Fernox F2 Central...

Newbie question I realise! What is the best way for me to manually flush the cleanser out of my central heating (open Vented) prior to dosing with inhibitor?? Do I close all but one radiator at a time and run water from FE until that single radiator is running cleanly and then move onto the next...

After reading Shaun`s informed comets on replacing inhibitor, I want to ask, is this normal? When my boiler was put in i think no flush was done. I assume inh was put in. It was a bit of a budget job. Since no flushing was done I was thinking of taking off the rads individually and flushing...

After installing new rads no inhibitor was used, the reason given was that it can cause problems rather than prevent them. The system has been without for approx 4 years now and I've got an Atmos multi boiler, is this advice correct? thanks.

Seems like in typical domestic systems, people just replenish as if none, however in our scenarios that isn't adeqaute or practical Rather than duplicate a thread, can anyone give me some help with this that I posted in the central heating forum...

The two most common branded products, Sentinel and Fernox, offer simple test kits for their own products, they claim that they are different chemicals, so their test kits are specific to their product. Additionally not all our clients us the 'retail' brands. As we work on many different systems...

Just came across this ridiculous product on amazon which is basically some overpriced inhibitor, all inhibitor is overpriced so whatever, but a. this is aimed towards DIY market - imagine an average DIYer trying to put inhibitor in a sealed system.. b. it makes completely false claims i.e 17%...

hi we have had a new combi boiler and some extra rads fitted last week. the installer has fitted magna clean micro 2 and has stated he has filled it with MC1 protector. We had small leak on system so have had to top u system several times since but we have found leak now and fixed it. while...

I have had severe problems with sludge in my CH system. The sludge has now been cleaned out and to try and prevent this happening again I gave the system a dose of inhibitor. This was fine for a few days but then I started getting a strong smell from the hot water. The water tank is an Elson...

Hi there, I normally use Sentinel x100 for replenishing central heating inhibitor, a bit pricey however I have seen a product called sure graft at plumbase, just wondering what people think to it. Looking at the state of some of the central heating contents I have drained down recently...

I am adding a couple of radiators to my house and the boiler installation sheet (11 years ago) shows an inhibitor "Salmar". Anyone heard of this and what is its equivalent as I would like to add some inhibitor

Just hear from a plumber friend that on a sealed sstem he no longer fills with inhibitor as it increases the conductivity of water & hence corrosion! He fits a spirovent de-airestor instead which seems like a fancy micro bubble air vent! Anyone else heard of this, surely some fernox added to a...

Have been asked what I would recommend for a inline scale inhibitor? Not really my specialist subject area & would be interested to know for my own information too. Thanks all.
