USER INSTRUCTIONS
The hot water in your home is provided
by a high specification storage system
which will give you many benefits.
WELCOME TO YOUR THERMAL
Simple to operate and exceptionally
STORAGE SYSTEM
efficient in operation, your PulsaCoil
PULSACOIL 2000 - THE POWER 2000 Thermal Store is probably different
BEHIND YOUR DOMESTIC HOT to any water heating system you have
ever experienced before. This booklet
WATER
will explain why and how you can get
the most from it.
Issue 6 : November 2004
OPERATING CHARACTERISTICS
- with a PulsaCoil 2000,the domestic hot
water you use at the tap is not stored
but is produced instantaneously. This
has the advantage of reducing the
risk of contamination from things
like Legionella as well as reducing
the risks of scalding by allowing the
temperature of the hot water at the
tap to be controlled at about 55ºC.
However, this also means that when
you open the tap, the temperature
takes a little time to stabilise.
- the reason is simple; tepid water in
the house pipework arrives at the
tap first. Then the system “senses”
that a tap has been opened so
heat exchange is started and the
domestic hot water will go fully hot
to sterilise the pipework. Following
that the controller will kick in and
the supply will settle at 55ºC
(approximately).
- water should not be delivered to the
tap below 50ºC for health reasons;
see HS (G) 70 HTM 2040.

This system delivers fresh water from
the mains supply to the hot taps and is
designed to fulfil three basic needs.
1. Deliver hot water at good
pressures whenever you need
it
2. Operate as efficiently as
possible to cost-effectively
meet your household needs
THIS APPLIANCE SHOULD BE
LEFT PERMANENTLY CONNECTED
TO THE OFF-PEAK ELECTRICAL
SUPPLY AND NOT SWITCHED
ON AND OFF WHEN HOT WATER
IS NEEDED. PULSACOIL 2000
MODELS (EXCEPT MODEL PC125)
ALSO HAVE AN ON-PEAK BOOST
WHICH CAN BE SWITCHED ON FOR
AN HOUR AT A TIME TO PROVIDE
A BOOST TO THE TOP PART OF
THE STORE ON DAYS WHEN A
LARGE AMOUNT OF HOT WATER
IS REQUIRED.

3. Provide hot water to every tap
that has not deteriorated in
storage tanks
USER INSTRUCTIONS
1. DELIVER HOT WATER AT GOOD Your Thermal Storage System is
PRESSURES WHENEVER YOU
designed to provide all the hot water
NEED IT
you are likely to need under normal
circumstances, and deliver that hot
water at a pressure comparable with
your cold water mains. This means
that you can enjoy powerful showers
without the need for a separate pump,
or fill a bath with hot water in minutes.
2. OPERATE AS EFFICIENTLY AS
POSSIBLE TO COST-EFFECTIVELY
MEET YOUR HOUSEHOLD NEEDS
Your Thermal Storage System will
ensure that the energy it needs is
minimised, avoiding costly use of fuel
by taking advantage of off-peak tariffs
whenever they are available.
Hot water is available any time you
need it when the system is switched
on, summer or winter.
3. DELIVERING HIGH QUALITY
WATER TO EVERY TAP
With traditional systems which have a
cold supply cistern in the roof space,
there is always the risk that the
tank could become contaminated by
dust, birds or insects. The PulsaCoil is
connected directly to the cold mains
and therefore even the hot supply is
pure high quality water every time.

The Gledhill Thermal Store is the heart
and brain of your hot water system.
It stores hot water at a constant
temperature and incorporates a
highly efficient plate heat exchanger
which heats the hot water for all your
domestic needs. The Thermal Store
is superbly insulated and so the hot
water stored has a very low heat
loss.
WHAT IS A THERMAL STORE ?
HOW DOES THE SYSTEM DELIVER HOT The water delivered to the taps and
showers in your home is supplied at
WATER AT HIGH PRESSURE?
high pressure because it uses the
mains pressure of your cold water
supply. The PulsaCoil is connected
to the mains system and the water
passes through a highly efficient heat
exchanger to raise its temperature
before it travels to your taps and
showers. Because it is so efficient, both
high flow rates and high pressures are
available to give the best performance
for both baths and showers.

PULSACOIL USER INSTRUCTIONS
Off-peak supplies will automatically
be used to heat the thermal store. You
will also have the option* to switch
on to the on-peak electricity supply
when necessary to provide a ‘boost’
to the top part of the thermal store
to achieve the most efficient way
of satisfying your demands on the
system.
USER INSTRUCTIONS
WHY ARE THERE NO WATER CISTERNS Water tanks in the loft are required
principally for the traditional domestic
IN THE LOFT
hot water system to give a better ‘head’
of water - which is basically determined
by the height of the cistern above the
tap being used. In most cases, the higher
the cistern, the greater the pressure.
Because the Gledhill system uses the
pressure from your cold water mains,
these cisterns are not required.
This removes any worries about freezing
or contamination of the cold water
system from insects, dust, birds etc and
leaves more space for storage should
you decide to use it.
The plastic feed tank should have been
filled to the water line by the installer at
the time of commissioning.
PLASTIC FEED TANK
The water level in the plastic feed tank
should be checked on a regular basis,
generally 3-4 times a year, and topped
up when necessary to approximately
half way.
Once the level has been topped up or
after it has been checked, ensure the lid
has been securely replaced.
An optional sight glass can be fitted to
the side of the feed tank, to overcome
the need to remove the lid to check the
water level.

USER INSTRUCTIONS
WHAT IF THE SYSTEM DEVELOPS A If your PulsaCoil should develop a fault,
FAULT ?
during the warranty period, switch
the unit off and contact your house
manager/installer. Do not attempt to
remove or adjust any component part
yourself.
If the developers warranty has expired
contact the manufacturer if you have
an active Service Agreement.
The off peak controller adjacent to
the PulsaCoil will have a manual boost
switch/facility. This should be switched
on for an hour during late afternoon
to provide a boost to the top part of
the Thermal Store on days when a large
amount of hot water is required.
If you are considering changing your
electricity supplier it is important
that you ensure they are able to
provide at least the same tariff. If not
the operation and cost of running
the appliance will be affected.
