Power, Durability, and Unrivalled Efficiency

The ACV HeatMaster 25C (A1002322) is an all-in-one solution, a powerful and compact combi boiler combining heating and hot water generation to save space, reduce energy use, and speed up installation. It’s the reliable heart of your property’s heating system, built for superior performance.

At its core is ACV’s "Tank-in-Tank" technology, featuring a durable, corrosion-resistant stainless steel cylinder that reheats incredibly quickly. This provides a plentiful supply of hot water, ending the wait between showers. The robust cylinder requires no anode protection, lowering maintenance, and is backed by an incredible 25-year guarantee for peace of mind.

Operating in its most efficient condensing mode, the boiler reuses latent heat to lower fuel bills and reduce your carbon footprint. Its low NOx emissions (<24mg/kWhr) qualify for two BREEAM credits, making it ideal for sustainable building projects.

The standardised ACVMax control system simplifies management, while the included unvented system kit and LPG conversion kit offer flexibility. Safety is paramount, with water stored above to mitigate legionella risk. With a heat exchanger backed by a 10-year warranty, the ACV HeatMaster 25C Condensing Boiler XB600001 is a smart, long-term investment in comfort.
