| Advantages Over Linear Pulsed Boilers
| Reduced Noise Level
It is well established from aircraft engine practice that noise is dependent on exhaust velocity, and a 7th power dependence is assumed. In Gasmaster boilers, exhaust gases flow in a radial outward direction through the entire gap, between the coils, at
the perimeter. Whereas in linear units, the gases exhaust through a relatively much smaller cross sectional area of the tube. | | Therefore, the velocity of the exhaust gases in Gasmaster boilers and water heater is much lower than that in the linear units. This results in a much lower noise level in Gasmaster boilers and water heaters. In fact, the operation of the products are as quiet as a conventional unit. No Vibration
The linear pulsed boilers operate at very low frequencies (at times below 10 Hz). In comparison, Gasmaster boilers and water heaters operate at an average frequence of 200 Hz. Thus, unlike linear units, Gasmaster products do not produce any vibration which may be transmitted through the floor. It, therefore, does not require any special pad to isolate it from the floor, as is the case with linear units.
Increase Range Of Output Capacity
To transfer heat efficiently, the heat producing apparatus needs to have sufficient "heat transfer surface". This is why all base-board radiators are finned. To increase
the output capacity, the input energy of the boiler must be increased proportionately. This results in corresponding increase in the volumes of combustion chamber and tail pipe. Because of the cylindrical geometry of linear pulsed boilers, the surface/volume ratio decreases as the volume increases. That is, the available heat transfer surface does not increase proportional to the volume. This leads to a consequent decrease
in heat transfer efficiency. The optimum limit for high efficiency in linear pulsed boilers is 120 kBtu/hr (= 38.1 kW). Manufacturers have been able to increase this limit to 1 mBtu/hr (= 293 kW) by increasing the length of heat exchanger and adding other peripheral components. This results in significant increase in the weight, size, hardware complexity, and production cost of linear pulsed boilers. In contrast, because of the radial (circular) geometry of Gasmaster boilers and water
heaters, the surface/volume ratio remains almost constant as the volume increases, thus efficiency remains constant as output capacity increases.
Ease Of Production/Repair
Compared to linear pulsed boilers, Gasmaster boilers and water heaters are very simple to produce and almost maintenance free. Unlike linear units which incorporate a very complex heat exchange system, Gasmaster products comprise two (or more)
stainless steel coils, as described above. All control components are off-the-shelf products. Incorporation of a micro-processor based control system has rendered it easy to install and almost maintenance free.
Furthermore, unlike linear pulsed boilers, Gasmaster boilers and water heaters do not use a mechanical (flap) valve to control air and gas flow into the combustion chamber. Therefore, the boilers and water heaters do not incorporate any mechanical component, which would be susceptible to failure. Finally, the very simple gas train is installed outside the box, is easily accessible, and comprises off-the-shelf products which are available from normal sources of supply. The simplicity of the hardware, makes Gasmaster products easy to produce, and renders them almost maintenance free.
Superior Material
Gasmaster products are the only known high efficiency condensing boilers which offer stainless steel heat exchanger and housing, as standard feature. As discussed above, the choice of superior material results in significant increase in durability and useful life of the boiler.  Advantages Over Conventional Boilers |
