FIT SESI – FORGET SCALE

Story

– reduced emissions and reduced fuel bills

Limescale is a major problem in terms of energy efficiency and savings in hard water areas – which account for more than 60% of the UK. It’s a primary cause of higher levels of emissions and higher fuel bills. Fact.

So finding a way of addressing the problem and at the same time helping to comply with the new Part L of the Building Regulations makes a huge amount of sense. This is where the SESI from Salamander Engineering can help.

There’s a frightening selection of physical water conditioners on the market for specifiers and installers to choose from including magnetic, electrolytic, electrostatic, electromagnetic and electronic. The reality is that the science simply doesn’t exist to prove these all work, and why, perhaps more worryingly, they appear to work well in one property and don’t in another, just down the road, with the same water mains and same water hardness.

Fit a unit that is proven

So if you’re looking to fit a water conditioner, you need to fit one that is proven and which has the science to back it up. In these circumstances, an electrolytic physical water conditioner – and one from a respected name in the water treatment sector – is the ideal choice. Even better if it’s proven to work, based on an independent study undertaken by the Cranfield University School of Water Sciences.

The SESI from Salamander, part of the Sentinel Group, works by flushing the hard salts through the system. It uses a zinc electrode and a natural electrolytic process to flush hard salts through the system rather than allowing them to settle and build up as limescale. It’s environmentally friendly and cost-effective operation has been proven in tests over the last 20 years. In simple terms, the crystals of hard salts in suspension change shape as they pass through the SESI and are unable to ‘stick’ to the metallic surfaces inside the pipes and radiators that untreated salts can – and do, alarmingly quickly. The process also ensures the crystals retain that shape and don’t quickly revert to the old damaging shape as soon as they have passed through the SESI unit.

Electrolytic physical conditioners such as Salamander Engineering’s SESI offer the ideal solution to the problem. They have the advantage of being able to protect an entire household’s pipe system from the formation of limescale encrustation, without the use of chemicals or salt and without the need for any electrical power supply. With no magnetic or chemical effect on the water, the units provide a cost effective and environmentally friendly solution. SESI is WRAS approved and fits in-line on the incoming main, providing whole house protection against limescale. The unit is non-magnetic, requires no chemicals, is non-polluting, maintenance free and comes with a 5 year guarantee.

As well as delivering an answer to the problems of hard water, the SESI helps specifiers and installers to meet the requirements of Building Regulations Part L cost effectively. Part L now clearly states that “where mains total hardness exceeds 200 parts per million, provision should be made to treat the feed water to water heaters and the hot water circuit to reduce limescale build up.” SESI offers an immediate and very convenient answer to this.

Limescale build up is damaging and is reducing the efficiency of customers’ appliances by up to 12%. Restoring optimum efficiency levels could save customers up to £100 a year on their energy bills – as highlighted by British Water.

The average life of a boiler heat exchanger – the element that actually heats the water flowing through it – is 10 – 15 years. But in hard water areas, this can dramatically decrease to just 2 – 3 years. However, if a specifier or an installer is knowledgeable about the hardness of the water and specifies or fits a limescale prevention device such as SESI, this rapid deterioration can be prevented and the heat exchanger should remain efficient for its full lifespan.
