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.

How to stop limescale

LimeStop

Siliphos Limescale Inhibitor

Guaranteed to work!

Just £69 + £10 postage

LimeStop is a Siliphos-packed limescale inhibitor that is truly guaranteed to work - or your money back!

The LimeStop contains silicate-polyphosphate balls called Siliphos. This is a widely-trusted food-grade material proven time and again to inhibit limescale formation. Its ability to combat limescale deposits is really quite remarkable as it both lays down a protective layer on the walls of the supply piping and inhibits calcium deposits.

Keep limescale away

for just 9p a day!

Copper construction.

Brass fittings already fitted.

Sealed unit.

No need to replace Siliphos...

Discard after 2 years...

And fit a new one!

We are recommended by Gledhill to work on their hot water heaters. We supply and install heat exchangers for most of their appliances

Models such as the Cormorant, BoilerMate, PulsaCoil, Torrent, SysteMate and GulfStream have heat exchangers that are prone to limescale formation in hard water areas. There are two types of heat exchanger: ‘plated’ and ‘coil’. The coil type such as that fitted in the original BoilerMate and also in the Torrent are easily descaled. These exist in pockets of developments such as that at Rooksdown in Basingstoke. The plated type shown in the above photo is usually held in stock. If you are a heating engineer, or even just a domestic customer sourcing your own parts supply, then give us a call if you would like to order a heat exchanger. This is Gledhill’s part number GT017. £113 including vat, but plus postage.

Gledhill Service Engineers

We’re often phoned by consumers many miles away from our location. We will publish a list here as and when those engineers get in touch with us to be listed, though please be aware that it’s merely a list, not a recommendation.

If you are a heating engineer who works on Gledhill appliances then simply email us to be included here in link exchange.

FREE HOT WATER!

Yes, really!

Rather than spending £3,500 on a solar hot water system, simply put your money into an Energy Payment Trust (EPT), and it will pay your entire hot water bill for the year - every year - for 20 years!*

AMAZING! But true!

Yes, you read it right. Although a solar panel, which might cost the same or even more than an EPT, would only pay a portion of your hot water bill, an EPT will pay ALL of it!

No equipment needed

No pumps or valves

Nothing on your roof

Amazing!

Please contact us for full details

Or you can write to us at:

*Domestic systems only

If you wish to end your agreement at any time within the first year, you can have ALL of your money returned!

We strongly suggest you read THIS if you are looking for solar panels - then come back here and apply to pay into an EPT.

“Costs for a typical solar water heating system range from £3,000 to £5,000...and will save a gas consumer about £50 a year...Most solar water heating systems come with a 5-10 year warranty .”

Whereas...

An EPT will cost £3,500...

pay ALL of your hot water costs...

for 20 years!

For those who have read this far down, there is no such thing as an EPT - It’s just your bank account! Yes, that’s right. Put the money into your bank account (that you would have spent on solar panels) and the account will pay ALL your hot water bills for 20 years or more! Solar panels are a great way to throw your money away - or you could just send the money to me.

Global warming, the Central England Temperature and weather...

Central England Temperature

(CET)

The CET is a record of temperature of central England going back to 1659. We can therefore see how(if) the temperature here is changing. The CET temperatures are adjusted to account for a warmer immediately-local environment, though it’s not clear if proper account has been taken of this Urban Island Heat Effect, so the figures given in modern times may include a small warming bias. This means that it’s difficult to trust latest data against data from over 100 years ago. Hence my comparison of the last 10 years instead:

Last 10 years average 10.45c

2008 9.96c

2008 thus cooler by 0.49 deg c

Last 10 years average 10.41

2009 10.11c

2009 thus cooler by 0.30 deg c

Jan (last 10 years) 5.02 deg c

Jan 2010 1.4 deg c

thus cooler by 3.62 deg c

Feb (last 10 years) 5.03 deg c

Feb 2010 2.8 deg c

thus cooler by 2.23 deg c

Mar (last 10 years) 6.68 deg c

Mar 2010 6.1 deg c

thus cooler by 0.58 deg c

Apr (last 10 years) 9.04 deg c

Apr 2010 8.8 deg c

thus cooler by 0.24 deg c

May (last 10 years) 12.18 deg c

May 2010 10.7 deg c

thus cooler by 1.48 deg c

June (last 10 years) 15.04 deg c

Jun 2010 15.2 deg c

thus warmer by 0.16 deg c

The above shows that the current temperatures are COOLER than the 10-year average. This is not what you are told, of course, as the Met Office don’t appear to want you to know it! So if you think that it’s chillier than you’ve been used to for the past decade then you’re right, it is! But don’t expect the Met Office or the BBC news to tell you this...they don’t want you to know.

Scalgon are the recognised experts in descaling and heating system power flushing - 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.

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 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).
