Which type of boiler should be utilized for hot water systems?

Using a low pressure hot water boiler for hot water systems is ideal because these boilers are specifically designed to efficiently provide hot water at relatively lower pressure levels, typically below 160 psi. This lowers the risk of handling high-pressure steam, which can be hazardous and requires additional safety measures, maintenance, and inspections.

Low pressure hot water boilers operate at optimal temperatures that easily meet the heating demands for residential and light commercial heating applications, making them suitable for hot water systems. They effectively circulate heated water through piping systems to radiators or heating coils, ensuring consistent and safe heating.

In contrast, options such as high pressure steam boilers are intended for generating steam and operate under significantly higher pressure, which is unnecessary for a hot water system. Medium pressure hot water boilers are more suited for larger scale applications but are not typically needed for standard hot water systems. Combination boilers can provide both hot water and heating, but their design might not be as efficient or effective for dedicated hot water systems as low pressure hot water boilers.
