As rust is magnetic, all that needs to be done to keep a heating system clean is
to install a strong magnet in the waterline. The magnet will filter out the particles
and collect them. But when we looked at manufacturing such a device, we were astounded
at the quality of some of those available. Often cheap plastic, with cheap valves.
And then there’s the issue of whether they can actually do the job. We have seen
‘magnetic filters’ with extremely small magnets, and some of them not even neodymium
magnets! We think that if the price is cheaper than our product...then that tells
you everything! So we set out to manufacture a magnetic filter that was big enough,
and strong enough. It had to be metal construction, but it also had to have a BIG
magnet capable of performing. The MagnaMate was the result...
The MagnaMate uses a N42-grade, rare-earth, neodymium magnetic rod
...similar products do not!
The MagnaMate truly is all-metal construction
...similar products can be cheap plastic!
The MagnaMate is guaranteed for 25 years
...similar products might come with a 2-year guarantee!
Can the MagnaMate be fitted on larger systems than typical?
Yes, although it is standard in 28mm (with 22mm optional) two units fitted in parallel
will provide protection for 42mm systems. We provide two MagnaMates for just £329
(includes FREE delivery) - you just have to add the 42mm tee pieces.
Should I fit the MagnaMate horizontal or vertical?
We always suggest vertical. However, it CAN be fitted horizontal (tails up) if required.
Is the MagnaMate really ‘all-metal’?
Yes, totally. It will withstand extraordinary system temperatures and pressures...where
others might fail.
Can I add chemicals to the system through the MagnaMate?
Yes, and extremely easily. The MagnaMate has a volume (with the magnetic rod in place)
of 1 litre. So simply drain the MagnaMate, take the magnetic rod out, pour the chemical
in, replace the rod. Done!
Is it tamper-proof?
Yes, unlike similar products to ours, the MagnaMate’s magnetic-rod cap can only be
removed using a pair of pump pliers. There is nothing for some inquisitive child
to press and cause a system leak!
How is it sealed?
The MagnaMate uses a simple, everyday, pump valve union, and hence a pump valve washer.
So NO special seals are required - nothing to leak!
Is the magnetic rod really N42-grade neodymium?
Yes, unlike many others we have seen, we manufacture a ‘magnetube’ (a highly magnetised
tube) of N42-class neodymium magnets (20% stronger than N35). We have seen magnetic
filters using ferrite magnets in the water line. In our opinion, they are only suitable
as a weight for sea-fishing.
Can it be fitted straight from the box?
Yes, you have to install valves, but the MagnaMate comes ready assembled, ready to
What are the dimensions?
It is 275mm in length by 70mm in width.
Where should I install it?
Always on the return pipe if possible.
What’s this about an amazing guarantee?
We guarantee the structural integrity of our products for 25 years - meaning that
no welded joint will leak. Everything will stay together as it was the day it was
made. And remember, each one is hand-made. This is what sets our products apart from
others. We are so sure of the quality of our products, that we are able to provide
such an extraordinary guarantee. Rival manufacturers are evidently unsure of the
integrity of their product(s), so give, what we would call, an inadequate guarantee.
Is the MagnaMate a British product?
Yes, we're proud to say it is. It is a quality product hand-made in England, not
China - like so many similar units. We even manufacture the core magnetic rods, by
hand, not import them from China.
Why don’t you sell the MagnaMate in plumbing merchants?
Because by the time they have added their mark-up charge, it would make it too expensive.
You get it the cheapest possible by buying direct from us.
Does the MagnaMate filter non-magnetic particles?
No, there is no need in the vast majority of cases. If you should require a non-magnetic
filter for any reason in addition to the MagnaMate then install a Y strainer, sized
for your needs. But if you have non-magnetic particles in the system, you should
be finding out why.
How do I clean it?
Turn the valves off, place a small bowl under the bottle and open both the air vent
and drain plug. Unscrew the top union nut and the magnet can be lifted out. Slide
the collar down the magnetic rod over a drain.
Can I get next working-day delivery?
Yes, and it’s FREE, but you must order before 3.00 p.m. PLEASE NOTE that next day
delivery cannot be 100% guaranteed - we are at the mercy of couriers!
I want one, but with alterations, can you do that?
Yes, we can! We can build BoilerGuard/MagnaMate-based magnetic filters to your exact
specification. Just email us. We can add high-temp magnets, or ports 180º faced,
for example. Or maybe labelled with your company name/logo. Our MagnaMate is 275mm,
but we can supply longer magnetic filters.
