Heater produsces - heat recovery finds heat and reuses it
The difference between a mobile gas water heater and a standard gas water heater is that a MH unit will use an outside air intake for combustion. That is the most important difference.
A heat exchanger is a device that transfers heat between two or more fluids without mixing them, allowing for efficient thermal energy exchange in processes like heating, cooling, or energy recovery. In contrast, a heater is specifically designed to increase the temperature of a single fluid, typically by adding energy to it, such as in electric or gas heaters. While both devices involve heat transfer, their functions and applications differ fundamentally.
Radiant heaters heat objects nearby them such as furniture and are usually cheaper. Regular convection heaters actually heat the air temp in the room.
Electricity energy is converted into internal energy through work. As the internal energy of the heater increases so, too, does its temperature. Energy is then lost to the surroundings through heat transfer. The change in the heater's internal energy is the difference between the work done on the heater and the heat transfer away from it.

what is the difference between product analysis and heat analysis
Terminal temperature difference (TTD) is the temperature difference between the hot and cold streams at the end of a heat exchanger. It is a critical parameter in the design and operation of heat exchangers, as it directly affects the rate of heat transfer and the overall efficiency of the system. A smaller TTD generally leads to a more efficient heat transfer process.
Cool touch heaters are made of ceramic and aree very safe, while mica radiators are hot to the touch but produce much more heat.
The key differences between a heat pump water heater and a gas water heater are the energy source they use to heat water. A heat pump water heater uses electricity to transfer heat from the air or ground to heat water, while a gas water heater burns natural gas or propane to heat water. Heat pump water heaters are more energy efficient but may have higher upfront costs, while gas water heaters are typically cheaper to install but have higher operating costs.
