Featuring intelligent hot water preheat and OpenTherm technology as standard, means the Intergas Rapid 25 is efficient in everything it does.

For an Installer, all the key parts in the Intergas Rapid 25 are made from copper and brass and are very easily accessible. The boiler case is removed from the front to expose the built-in 8 litre expansion vessel, so there is no struggling to test and recharge the expansion vessel each year.
