The most exciting product development in the field of mains pressure hot
water for years.
|
Thermal stores (otherwise known
as Heat Stores) are fast
becoming the preferred option in the field of mains pressure hot water when
compared to the
complications and hazards of an unvented hot water cylinder. |
Building
Regulations in the United Kingdom state: Any
vessel storing more than 15 litres of hot water under pressure is subject to
section G3. This means virtually ALL unvented cylinders, but not
so the TORRENT.
Because the bulk of water in the Torrent heat store is vented
to atmosphere it presents no danger from explosion, is therefore exempt of regulation
and does not require a specialist installer.
The water in a Torrent cylinder is used
solely to
store energy in the form of heat, nothing else. The clever part is what the
cylinder does with its energy. |
Torrent Multifuel Thermal Store
Cylinders are available in the following models -

1 |
The Torrent MultiFuelStore OV utilises an
open vented boiler and / or direct electric immersion heaters as it
primary energy source. It comes fitted with tappings for a
woodburning or solid fuel boiler as standard, which can be blanked
off if not required at the time of installation.This model is ideally suited to
the typical household offering the added benefit of easy upgrade
to a mains pressure system during refurbishment. |
2 |
In situations where no
gas or solid fuel source is available the Torrent MultiFuelStore
OV can be used exclusively from the two 3kW electric immersion
elements which will provide both hot water and heating for the
property. The obvious application is apartments where no gas main is
available but this could also be appropriate where electricity is
available from a renewable or low carbon source. |
3 |
The Torrent MultiFuelStore
SP utilises a sealed system boiler as its primary energy source. It
comes fitted with tappings for a woodburning or solid fuel boiler as
standard, which can be blanked off if not required at the time of
installation. An auxiliary heating circuit can be connected from the
store in which case the solid fuel source will provide
energy to the auxiliary heating circuit. An immersion element is
provided and it is normally envisaged that this will be used as an
emergency electric back-up for hot water and to provide emergency
energy to the auxiliary heating circuit. However, if a low carbon or
renewable electricity source is available then this could be
connected to the immersion element to provide heat input to the
thermal store, decreasing the use of the fossil fuel boiler and
hence reducing running costs. |

An advanced vented thermal store providing mains pressure hot water with multiple
input capability from SOLAR, WOOD BURNER, BOILER, GROUND SOURCE or AIR
RECOVERY and AGA and the facility of
running central heating directly from the store. |
5 |
Rather than operating with a conventional carbon fuel boiler
as the main energy source this appliance has been designed to
operate with an air or ground source heat pump. However it still
provides mains pressure hot water from an open vented thermal store
and enjoys all the other benefits outlined previously for the other
Torrent MultiFuelStore appliances. |

TORRENT Multifuel
thermal store
HP SOL
Combining all the benefits of the Torrent MultiFuelStore HP, the
Torrent MultiFuelStore HP SOL allows the combination of heat pump,
solar energy and wood burning stove in the same system, making what
must be the ultimate alternative energy cylinder. |
TORRENT range of
thermal stores:

Thermal Stores are simple to install
overcoming the dangers, complicated installation and expense associated with
unvented cylinders, yet they produce the very same thing - Mains Pressure Hot
Water. Yet they offer so much more.
So easy to install, they are ideal for
upgrading existing systems and meet the needs of the refurbishment market perfectly.
New generations of thermal store now facilitate an interface between
multiple heat inputs, storing energy from different heat sources, providing
mains pressure hot water and contributing to a household heating system.
A
thermal store is the simple, safe way to provide mains
pressure hot water to your taps. Suitable for use with numerous heat sources
including Gas and Oil boilers, Wood burning stoves, heat recovery systems, AGA's and fully electrical
installations including Economy 7. As you can see, a Thermal Store is even
safe to use with uncontrollable heat sources that are simply too dangerous
to connect to an unvented cylinder.

What is a Thermal Store?
|
A Thermal Store is a vessel which
acts like a battery, but instead of storing electrical charge it stores heat.
It is able to accumulate heat from numerous heat sources simultaneously. The
beauty of a Thermal Store is the fact that the cylinder operates at
atmospheric pressure - this is to say the cylinder is not pressurised, it is always vented to atmosphere and therefore presents no danger
(i.e. risk of explosion as with an unvented cylinder). To see a couple of
examples of the power released when an unvented cylinder explodes click

and

A
Thermal Store is able to produce mains pressure hot water by immersing a
high efficiency heat exchanger in the hot water inside the cylinder. By
passing mains pressure cold water through the heat
exchanger it rapidly becomes hot water then emerges from the cylinder and
speeds off to the outlet point hence - Mains pressure hot water from a
vented cylinder! This is
what makes a Thermal Store inherently safe.
The Torrent Multifuel store is available
with or without a boiler coil allowing it to be used on a fully open vented
system (OV model) or with a sealed primary and radiator circuit (SP model).
The OV model can also be used on a system exclusively heated by electricity
and is ideal for 'low cost' tariffs such as Economy 7. The Torrent is
also available in models that include heat exchangers for Solar input and
others that maximise storage of energy from Heat Pumps and Air Recovery
systems. |

Open vented - highly
insulated, efficient and most importantly - SAFE. Because the TORRENT does
not store more than 15 litres of hot water under pressure it is exempt G3
Building Regs (UK) which means you do not need Building Regulations Approval
to install one, certification by the installer or annual maintenance.
Easy to install - the TORRENT can be
fitted simply into existing systems, including the existing boiler and controls, where
appropriate. Can be fitted without specialist certification.
Does not require - expensive safety
controls or temperature and pressure relief pipework to the outside of
building.
Torrent has no need - for
an external mains pressure expansion
vessel as this is incorporated into the heat exchanger in the cylinder.
Thermal Stores do however require a small Feed & Expansion tank [F&E] into
which they breathe. Wiring is the same as any traditional Y, S or W plan system.
Long Life - the TORRENT is manufactured
from copper sheet to BS2870. The computer designed heat exchangers are
produced from finned tube and incorporate a patented expansion chamber which
is sealed for life.
Economical to install - No specialist
fitters required to install a Torrent. Inherently safe by nature, you won't
be needing to pay premium prices to your installer. |
