ACV Heatmaster 70TC Condensing Boiler 05652401

High hot water demands in a busy household or commercial setting require a boiler that is both powerful and efficient. The ACV HeatMaster 70TC is engineered to be that high-performance, reliable solution. Perfect for large homes and light commercial spaces, this boiler delivers exceptional heating and hot water, exactly when you need it.

The Ultimate High-Performance Boiler

The morning rush in a large family home or the high demands of a small guesthouse require a boiler that will not let you down. The ACV HeatMaster HM70TC Gas Fired Condensing Boiler 16.7–68.2kW No Flue 05652401 is engineered for these exact challenges. It provides a constant and plentiful supply of hot water and reliable heating, so you never have to compromise.

The secret to its incredible performance is the unique "Tank-in-Tank" technology. This system features a stainless steel hot water tank that sits directly within the boiler's primary water, acting as a massive heat exchanger. This isn't just a minor feature; it's a fundamental design choice that prevents the common issue of temperature drops when multiple taps are used at once. The result is an exceptional hot water supply with incredibly rapid heat-up times, perfect for back-to-back showers or commercial kitchen use.

The Heatmaster HM70TC is designed to save you money as a high-efficiency condensing boiler. Its official SEDBUK Band A rating places it in the top tier for energy efficiency, which translates directly into tangible savings on your gas bills. This high output gas boiler captures latent heat from the flue gases that would otherwise be wasted, leading to significantly lower energy bills and a reduced carbon footprint. Its intelligent, modulating pre-mix burner adjusts its output anywhere from 16.7kW to 68.2kW, ensuring it only uses the precise amount of energy required at any given moment. This smart performance means no wasted fuel, just efficient, on-demand heating.

When you invest in a new boiler, you need it to be a long-term solution. The Heatmaster 70TC is built from high-quality stainless steel, which offers excellent resistance to corrosion and promises long-lasting reliability. This robust build gives you the peace of mind that you're installing a durable workhorse, not a temporary fix. Its versatile and compact design makes it the ideal heating solution for larger domestic properties, guesthouses, or even sports clubs where performance is paramount. For complete system longevity, consider pairing it with quality pumps from our Pumps Category, featuring trusted brands like Grundfos and Lowara.
