Torrent Indirect-Sp - gledhill TORRENT DIRECT Design, Installation & Servicing Instructions

The Torrent Indirect-OV models can be plumbed using the traditional 'Y' or 'S' plan control
arrangements or alternatively, the central heating can be supplied using a separate pump directly
from the store as described in section 4 of this manual. The technical data of the Torrent Indirect-
OV models is presented in table 2.4 in section 2.
1.3

TORRENT INDIRECT-SP

Torrent Indirect-SP is a vented primary hot water store i.e. the cylinder is designed for use with a
gas or an oil boiler and provides mains pressure domestic hot water (figure 1.4). Like all other
Torrent models, the domestic hot water is heated instantaneously by means of internal heat
exchangers. The primary thermal store of the Torrent Indirect-SP is heated indirectly by means of
a primary heat exchanger (primary coil) and is used for heating domestic hot water only.
The Torrent Indirect-SP is primarily designed for use with sealed primary heating but it can be
used for open vented systems provided separate cold feed and open vent are used for the
heating circuit. The Torrent Indirect-SP models can be plumbed using the traditional 'Y' or 'S'
plan control arrangements as described in section 4 of this manual. The technical data of this
range is listed in table 2.5 in section 2.
1.4 TORRENT-RE – FOR USE SOLAR / WOOD BURNING STOVE / AGA
The Torrent-RE-Solar is based on the well proven, tried and tested Torrent range of thermal
stores described above. It is designed for use with solar thermal systems in combination with a
gas or an oil boiler. In addition to this, the Torrent-RE-Solar can also be connected to other
renewable energy heat sources e.g. wood burning stove, AGA. The connections for wood burning
stove and any additional connections for other heat sources or additional heating circuits can be
specified when placing the order.
All Torrent-RE-Solar models are available for use in traditional open vented (OV) heating systems
as shown in figure 1.5 or with an additional primary (boiler) heat exchanger for use in a sealed
primary (SP) heating systems as shown in figures 1.6. However in both cases the thermal store
is always open vented so that other renewable heat sources can be connected to it safely. In both
variants, the solar panels heat the store by means of a solar heat exchanger inside the store.
In the Torrent-RE-Solar OV models, the thermal store is heated directly by the boiler and/or the
wood burning stove (if fitted) and the central heating is supplied from the thermal store. In the
Torrent-RE-Solar SP models, the thermal store is heated indirectly by the boiler and directly by
the wood burning stove (if fitted) and the central heating is supplied directly from the boiler
circuit. The technical data of these models is listed in tables 2.6 and 2.7 in section 2.
1.5 TORRENT COMBI-PREHEAT
This Torrent variant is designed to provide solar pre-heated mains pressure hot water to a
combination boiler without the risk of legionella. The thermal store is heated either directly (e.g. a
drain back system) or indirectly by my means of an internal solar heat exchanger i.e. a
pressurised solar circuit). In both types, the thermal store is open vented. Horizontal models are
available for use in a loft space with restricted height.
A typical system configuration of solar heating system designed to provide pre-heated mains
pressure hot water to a combination boiler is shown schematically in figure 1.7. The technical
specification of the Torrent Combi-preheat models is shown in table 2.8 in the specification
section 2 of this manual.
