Scalgon
THE experts in limescale removal & prevention - and magnetite-sludge treatment
Scalgon are the recognised experts in descaling - a successful business for 28 years.
Our fully-insured service is highly regarded, and we are sought by many companies
and home-owners across a wide area. We pride ourselves on our service. We descale
ALL combination (combi) boilers, water heaters, Megaflo heaters, IMI Powermax heaters,
Gledhill heaters (Boilermate, PulsaCoil, GulfStream and Torrent, whether coil-type
or plated heat exchangers), Elsy & Gibbons (Elson) heaters, Range Flowmax and Albion
Mainsflow thermal store heaters, Santon electric heaters, and of course, pipe networks.
Although most of our work is combi boilers, we are experts at thermal store appliances.
Limescale inhibiting or removal is essential for your water heater to work effectively
in a hard water area - and is now a Building Regulations requirement where there
is hard water. Check out our GUARANTEED LimeStop limescale Inhibitor.
Descaling sounds like an easy task, but effective limescale removal depends on the
correct acid and method used. If the wrong acid is used, limescale will return more
quickly than it originally formed. If the incorrect method is used then the heater
will simply not have been fully descaled. We have carried out operations for Thames
Water, Rank Hovis McDougal, Reading University, Reading Borough Council, Sovereign
Housing Association, countless property letting companies, heating & plumbing companies
and housing management companies. NO ONE knows limescale better than us. If the best
service is most important to you then phone us on 0118 942 4981 or 0770 231 6157.

HARD WATER
Rain passes through rocks (in some parts of the UK) that contain calcium and magnesium. These minerals are filtered out of the rock by the rain water and pass into rivers and underground water-ways. This water is removed by the water company, cleaned and sent to your home. Although the water has been treated to make it drinkable it still contains the minerals. When this water is heated the calcium falls out and solidifies. If you boil a saucepan of water you’ll see it as very fine grains in the bottom of the pan. Of course, this sticks to kettles and anything else that heats the water - including your boiler. The principle areas of hard water are the Thames Valley, East Anglia and Kent. It IS possible to inhibit this ‘stickyness’ by using a physical limescale inhibitor such as our LimeStop.
The dark blue areas are where hard water is severe.
As the name implies, a heat exchanger exchanges the heat from one compartment to another. Usually this is in the form of a coil of pipe containing water, with flowing water around the coil. One of these water systems will be mains pressure and one will be atmospheric pressure or system pressure. The side that is mains pressure will suffer from limescale, whereas the water on the other side which is simply re-heated again and again, will not. Combi boilers usually have two heat exchangers. The primary heat exchanger contains system water, and doesn’t usually suffer from limescale. However, that primary-side water goes into another heat exchanger called a ‘plate-to-plate’ heat exchanger. This is the hot water heat exchanger. There are numerous plates - closely stacked - where the heat should be exchanged. In this case, the plates will clog will limescale. As plates become clogged, the water takes an easy path through plates that are not yet clogged. This has the effect of failing to exchange the heat. One of two things will usually happen (sometimes both). Either the water coming out of the tap will be just warm, or the boiler will overheat (as it cannot get rid of the heat being generated).
In our area?
We are the recognised experts for descaling Gledhill appliances. We cover a large
area around Reading - the ‘RG’ area. If you live outside of the area shown then you
may find our ‘labour’ charge for travel time to other areas uneconomic for you.
Landlords please note, payment must be made by BACS (bank-to-bank transfer) prior
to the work being carried out OR cash payment immediately upon completion of work.

Limescale and ‘sludge’ - what’s the difference?
This is widely misunderstood - even by some plumbers! Limescale affects hot water
(and heating) appliances where there is FRESH WATER. So usually a heat exchanger
will ‘scale-up’ only on the hot water side - because fresh water is continually passing
through it. It will only scale up on the heating side if fresh water has been passing
through that - through regeneration. Despite what you may read on the web, the picture
you can see above of a severely- scaled pipe is NOT what you would get in any heating
system. That degree of build-up would have caused the system to fail a long time
ago.
Instead, what mostly affects the heating side is ‘magnetite-sludge’. Essentially
this is simply your radiators rusting away. It can be addressed, and we have developed
a number of ways to do that. Principally that is by fitting one of our OWN magnetic
filters. We usually incorporate a light flush at the same time. Generally, we no
longer recommend a ‘power-flush’ as it so often can be largely ineffective. The magnetic
filters we install have been developed entirely by us, and are VERY effective magnetite-sludge
traps. They start at just £79.
Cold radiators at the bottom? This is what it looks like, and in your pump - and
the remedy!
