The endlessly modulating regulation automatically changes the boiler's capacity to your needs. The Compact HRE 30 SB is compatible with both standard 'on/off' thermostats and programmable room thermostats. The built-in frost thermostat protects against frost damage. The Compact HRE SB may be equipped with a hot water storage cylinder, allowing the boiler to also heat the hot water supply.
