Manual Storage Heater
Design and Construction
TTS heaters are an assembly of 6 primary elements:
1.
Case
- The attractively designed steel case is finished with a high degree of craftsmanship. All
surfaces painted with a neutral off-white baked enamel. This case is very strong and provides the
base upon which all other components are supported.
2.
Thermal Insulation
- The thermal insulation within the heater provides a key function in the
heaters' design and is a combination of Vermiculite panels and a micro porous type ceramic
material. The result is the ability to store heat within the brick core at temperatures reaching
675°C (1250°F) and yet provide surface temperatures on the case which are typically below 75°C
(165°F).
3.
Storage Core
- The actual heat storage device is an assembled core made up of refractory
bricks of feolite material, approx. 6 kg (13 lbs) each.
The bricks are identical and are delivered in packs of 2’s and 3’s (see Technical Data, page 14).
The bricks are moulded, high temperature fired and specifically formulated to provide the highest
specific heat and thermal conductivity for the maximum efficiency as a storage core.
4.
Heating Elements
- The electric heating elements are a metal sheath, rod type made of the
finest materials proven in millions of installations over the past 20 years. This element placed
within the special shaped storage bricks, provides for rapid heat recovery and an even application
of heat to the storage core.
5.
Charge Controls
- TTS heaters are equipped with two separate thermostat controls, the first is
the "Manual" charge thermostat which can be fitted with a control knob at the front of the heater.
This control is used to manually set the temperature level that the heater storage core will be
charged to during each charge period and thus the amount of heat stored. The second charge
control is a fixed setting "Safety" or high temperature limit thermostat, which will shut the heater
off if the other controls fail to limit the maximum temperatures.
6.
Fan Assembly
- The TTS heater utilizes a low-volume, slow speed fan to push heat from the
storage core when the wall thermostat signals the need for heat in the room. The fan assembly
also includes the discharge air-mixing valve used to keep the output
air temperature at a safe
and comfortable level. TTS heater fans are nearly silent in normal operation and should not cause
concern even in bedroom applications.
