An Economical Solution To Your The design of the Thrush Hot-Pak® facilitates the semi-instantaneous heating of water, allowing for a
constant supply of hot water to any commercial or industrial application. This pre-engineered system
provides an economical solution to the expense of large storage tank systems. In addition, its
space-saving vertical or horizontal design makes it ideal for tight installations.
