INTRODUCTION
Sureflow
Sureflow, 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
Savings
The 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.
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.

Three Phase Voltage OptimiserHOW ITWORKS
How It Works
1. 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.
Fitting
Sureflow 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.

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.

Three Phase Voltage OptimiserTESTIMONIALS
TESTIMONIALS
BELA 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."

Three Phase Voltage OptimiserFAQS
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.
