INTRODUCTION

SureflowSureflow, the unique device with no moving parts that reduces oxygen to an inert level (below 0.5 ppm) to prevent corrosion within heating systems.

Sureflow creates a vortex so that trapped air and especially dissolved air within the heating water can be removed through an automatic air vent.

This eliminates the formation of magnetites in the system and results in increased flow and return temperatures by an average of 10°C and an increase in domestic hot water supply by over 2°C

SavingsThe potential savings are significant:

• Average household will save £150 per year

• Over its lifetime it could save £6,000 on fuel bills and 40 tonnes of CO2 emissions

• Increased peace of mind

The average household that installs the Sureflow will save around £150 a year on heating bills, giving average paybacks within 36 months based on a typical fuel spend of £1,100 per year.

As Sureflow has a minimum life span of 40 years, over the product’s lifetime it could save up to £6,000 on fuel bills along with 40 tonnes of CO2 emissions.

Of particular benefit to social landlords is the reduced cost of maintenance associated with the installation of Sureflow.

This saving can be as much if not more significant than the savings associated with heating bills.

TESTIMONIALSBELA J (WEST MIDLANDS)

“As soon as the Sureflow was installed I found I had to turn down the thermostat on the boiler because the radiators got very much hotter - which implies that the Sureflow is achieving something significant.”

RETIRED PLUMBER (WILTSHIRE)

“Our oil consumption fell in the year after the Sureflow was installed. We closely monitor our use of oil and have done so for the past ten years at least. Whilst no two winters are the same in terms of weather there was a definite reduction in oil consumption post Sureflow installation and that reduction was around 10%. There was also a noticeable reduction in system noise as the air was purged from it although we still get the occasional bubble moving around the pipes. This is more likely to be caused by the layout of our pipework than any issue with Sureflow.”

JENNIFER RICHARDS (ABERDEEN)

“I cannot say precisely how much the Sureflow has contributed towards savings because of the very cold winter and other improvements I have made to my home, however I would say the heating bill is about 1/3 the average for the house size we have and it logically must be part due to the Sureflow, there is no rust buildup in the water either so the claims of how it works seem to be correct.”

MRS. ETHAL WHITE (MANCHESTER)

“The Sureflow has been fitted for a little over a year (I think) and there has been no need to bleed the system during that time.”

MR. BILL GRAYSON (SOMERSET)

“I installed my Sureflow some 2 years ago and since then have been anxious to determine whether it has given any tangible improvement to my central heating system performance. I can say that bleeding of radiators is now a forgotten art as far as our household is concerned - air just does not get into the system. We run the boiler at a lower temperature as recommended and find there is no loss of heating performance across the home - indeed if anything we feel that the system is much less stressed even in the depths of winter. Overall we feel that Sureflow has made a significant improvement to our central heating system, improved its performance and reduced the overall running costs. The only evidence to support such a statement is that while fuel costs have risen quite dramatically, the cost of running our heating system has not increased and our heating engineer is much impressed by that experience.”

MRS TURNER (LONDON)

"An excellent system. Makes the hot water so much hotter and the central heating system so much quieter! I just know that, because the boiler is turned down a notch yet giving the same heat output, that we are for sure saving on our heating bills."

BENEFITS1. Average household will save £150 per year

2. Over its lifetime it could save £6,000 on fuel bills and 40 tonnes of CO2 emissions

3. Increased peace of mind





WHAT YOU GET• Reduced energy consumption: savings of 23.7% on heating bills (IT Tralee Result)

• Primary heating water with a Sureflow will become 10 to 12 degrees hotter, whilst using the same amount of energy

• Significantly reduced annual maintenance costs

• Reduction in CO2 levels

• Improvement in the way heat is transferred across indirect coils and heat exchangers

• Increase in comfort levels

• Almost silent running: much of the noise made by a heating system is associated with the air in water

• Known system problems cured, for example, uneven heating of radiators and noise associated with air

• Easy to fit, with only two connections

• Will work with condensing, non-condensing, oil and gas boilers, including combination boilers, as well as all types of heat pumps

• Significant help in alleviating fuel poverty

• Totally maintenance free**The automatic air vent may have to be removed and washed or replaced every few years. This is the equivalent of changing a bulb in a light fitting. We provide with the Sureflow a shut off valve, so that the air vent can be removed easily without having to partially drain down the system.

DON'T JUST COLLECT YOUR CORROSION WITH MAGNETIC FILTERS, PREVENT IT!

Sureflow removes the air and the dissolved oxygen, which causes corrosion, from the heating system water.

Without corrosion your boiler and radiators last longer.

The removal of air leads to a higher efficiency which means saving money on energy bills, up to 20% saving.

HOW IT WORKS











MRS TURNER (LONDON)





















How It Works1. Sureflow works in a very simple way by harnessing phenomena

created by the circulating pump.

2. As the water enters the Sureflow the action of the pump causes it to spin into a vortex. In the middle of the vortex there is a low pressure zone which is sufficient to draw the dissolved air from solution.

3. As the water reaches the outlet of the Sureflow the action of the vortex increases and the bubbles of air, now out of solution, rise upwards and are collected through a dip tube to be released from the system through an air vent.

4. With pre-fitted compression connections, installation couldn’t be simpler and there is no annual maintenance needed.

FittingSureflow should ideally be fitted as close to the boiler as possible but if this is not possible Sureflow can be fitted anywhere on the heating system and will still work. Sureflow can be fitted in a boiler room, kitchen, hot press/airing cupboard or any other location containing the flow and return pipes. This could even be in the roof space but in this case the Sureflow would need to be insulated.

FAQS

What size of pipe work can Sureflow be fitted to?Sureflow comes in standard connection size of 22mm to suit normal domestic heating systems. For heat pump installations and abnormally large domestic heating systems, Sureflow can be provided as a special order with 28mm connections.Is Sureflow either complicated or expensive to install?No. Sureflow has only two connections and an auto air vent, which is provided to install. Including the drain down and recommission installation should take no more than two hours. Is the Sureflow connected to electricity?No, the Sureflow has no working parts and does not require an electrical connection.I have a deaerator fitted, why do I need Sureflow?It was thought that fitting a deaerator would solve the problems of corrosion in heating systems, but, as we have discovered, they only deal with the symptoms. Some actually have a sludge trap, so are not deaerating fully. Sureflow, when installed, will reduce dissolved air to such a level, that even after years of continuous running the heating water will remain crystal clear.Can Sureflow be fitted to a tank fed or gravity system?Yes, Sureflow was originally designed to be installed with tank or gravity fed system to great effect. Is Sureflow required on a “Sealed” system?Yes, it was considered that a sealed system once purged of air would be free of air and therefore Sureflow would be unnecessary. It has been established that over time, even in sealed systems air infiltrates the heating system through valves, pumps, etc. and needs to be removed.What is the limitation to the types of heating system that Sureflow can be installed with?There are no limitations to the type of domestic heating system that Sureflow can be installed with. How quickly does the Sureflow affect the performance of a heating system?The effect on a heating system is almost immediate, then, over the next three to four weeks, there is a gradual improvement over and above the initial improvement. My heating system has had a corrosion inhibiter added, will Sureflow still work?Yes. All Boiler manufacturers provide corrosion inhibiters with new boilers. The inhibiter will not affect the way Sureflow eliminates dissolved air. I have a ground source heat pump. Will Sureflow work the ground loop?Yes. Recent research has shown that the addition of Sureflow to a ground loop may provide an increase in CoP. Can Sureflow be installed with oil boilers?Yes. Sureflow will bring about a benefit to oil, gas, lpg and electric boilers. Results may vary. I have an old fire back boiler. Will Sureflow help it become more efficient?Most certainly. Sureflow was developed from an original technology that was specifically intended for fire back boilers. I live in a flat with a fireback boiler and have constant problems with having to bleed radiators, will Sureflow help me overcome this problem?Yes. Sureflow has been designed to work with heating systems that have a very low feed and expansion tank. It will be a tremendous benefit to your system. It will eliminate all the air that is sucked in to a system with a very low feed and expansion tank very quickly before it can do any harm to your system. My system is quite old and has always been noisy. Can Sureflow help with this problem?Yes. The cause of the noise in this system is air that has formed bubbles which causes a “kettling” noise. Other noises such as gurgling are also caused by air. Sureflow eliminates dissolved and free air which will stop all the noises associated with air.I have a ground source heat pump. Will Sureflow be any benefit to the performance of it and how?There are two ways to improve the performance of a ground source heat pump. Sureflow may be installed with the ground loop in isolation. This will improve the rate at which the refrigerant absorbs the low grade heat from the ground. A second Sureflow installed in the primary circuit will improve the way the heating water conducts the heat from the plate heat exchanger.I have a combination boiler. Can Sureflow be fitted to it?Yes, The pump on a combination boiler is “on the return”, so Sureflow is simply fitted to the heating return pipe coming back to the boiler.

I have a “Condensing” Boiler, surely Sureflow cannot make improvements to this type of boiler?Because Sureflow is installed in the heating system, fitting it to a condensing boiler will still bring about big improvements to your system.What kind of improvement can Sureflow make to a Condensing Combination Boiler?Experience has taught us that with some types of condensing combination boiler, the main primary thermostat needs to be turned down by as much as a third. On other types, where the primary temperature is displayed, the initial reduction in primary temperature is around 10°C, with further reductions necessary.What primary temperature can a combination boiler be expected to run at with Sureflow installed?Where the temperature is displayed, a reduction of primary temperature down to 59°C is possible. Will the domestic hot water be affected by the fitting of Sureflow with a Combination Boiler?Because the d.h.w. temperature is limited to 50°C, there will be a slightly faster heat up, resulting in less waste water. How does Sureflow work with heat pumps?Generally, the pumping velocities of all types of heat pump are much higher than with gas boilers, Sureflow is installed on the “positive” side of the pump. The effect on heat pump is more gradual, because there is not the “sucking” effect, but the end result is a significant improvement to the performance of a heat pump.Does Sureflow lessen the performance of a heat pump?Just the opposite, with Sureflow in the ground loop of a g.s.h.p., there can be an increase in C.o.P of around 8%. Does Sureflow have a guarantee?We offer a ten year warranty and a money back guarantee if 10% energy savings are not achieved. Sureflow should outlast other components of the heating system such as radiators, valves and boilers.I have a large, old system with some radiators that never get as warm as the rest, will Sureflow make a difference?Yes. It won’t be instant, but after a couple of weeks all the radiators should be heating up and at the same temperature. Where can the Sureflow be fitted on the system, there is no room next to the boiler, can it be fitted in the loft?With a normal gas or oil heating system, Sureflow is fitted in such a position such as the airing cupboard where the pump “sucks” the water through it. If necessary, it can go in the loft or any convenient place. It doesn’t have to be close to the boiler.Can the Sureflow be made in white?Yes, our thinking on the colour of Sureflow has changed when we realised it would work with combination boilers which are normally in kitchens and have white casings. We originally made the Sureflow in black but now all of our Sureflows are white.How long will the air vent last?The air vent is a mechanical device which under normal circumstances will last a long time. Sometimes after a number of years, dirt in the system may prevent the valve seat from sealing. We provide with the Sureflow a shut off valve, so that the air vent can be removed easily without having to partially drain down the system.A simple rinse under a tap is sufficient to unblock the air vent. In some cases it may be necessary to replace the air vent which is the equivalent of changing a bulb in a light fitting.
