Vaillant ecoTEC Plus 624 24kW System Boiler 

The Vaillant ecoTEC Plus 624 24kW System Boiler is the perfect choice for medium-sized homes with 2-3 bedrooms and 1 bathroom or 1 en-suite. This boiler has a BTU output of 80,000 and a central heating output of 24kW, making it highly efficient and economical to run.

With a 1:6 modulating ratio for higher efficiency and low standby energy consumption, the ecoTEC Plus 624 is designed to be future-proof with a low energy and high efficiency pump. It also includes a flame lite detection system and automatic burner monitoring for safe and efficient operation.

The boiler has a modern design with a stylish platinum fascia and compact dimensions. It is SEDBUK band ‘A’ rated for fuel efficiency and has a fully modulating low Nox burner and fan (Class 5). The 2-stage frost thermostat ensures reliable operation in colder weather conditions, and the comprehensive boiler status/diagnostic display system and backup provide peace of mind. With easy access to all components from the front and removable side panels, installation and maintenance are a breeze.
