Replacing an internal boiler is incredibly easy. External boilers are also quite easy, once you understand the principles. Internal boilers are relatively easy to replace, but the internal repairs are a bit more complex. External boilers are more complex to replace, but the pump and separator tank are located outside, providing ample internal space for repairs. If you want a simple replacement, an internal boiler is a good choice. If the complex boiler room makes repairs difficult, an external boiler might be a good option.
