20 MainEco Heat
The boiler will be installed on either an open-vented or sealed
(pressurised) heating system. If you are unsure which type of
system you have consult your installer.
Sealed systems may require periodic re-pressurisation. If this is
required on a regular basis a fault or leak is indicated. Seek
advice from your installer.
