What are two things users must keep in mind while purchasing an electric boiler?
- One should bear in mind capacity, i.e., the amount of liquid the boiler can heat over any given period. Measured in BTU per hour, prospective buyers must know the amount of water a unit can heat and hold in an hour.
- The PSI rating, which is the amount of pressure the electric heat exchanger can safely contain is also important. Your vessel must meet The American Society of Mechanical Engineers (ASME) standards and any other criteria required for usage of the boiler.
How does an electric boiler work?
- Immersion heaters sit within the water radiating heat.
- Electricity heats these components which in turn heats the water.
- A circulating pump feeds the boiler and a tube allows the hot water to pass through to the necessary location needing the heat.
- With temperature and pressure gauges, one can check the state of the water inside the boiler.
