Our range includes products from established manufacturers such as Advantay and Gledhill, covering a wide variety of capacities and system configurations.<span class="PDq2pG_selectionAnchor"></span></p> <p dir="auto" data-start="1017" data-end="1466">Buffer tanks can form an important part of suitable heating and heat pump system designs by providing additional water volume within the system. Depending on the installation, this can help manage the relationship between heat generation and heat distribution, support system performance and help reduce unnecessary cycling of heating equipment. The correct tank type and capacity will depend on the design and requirements of the individual system.</p> <p dir="auto" data-start="1468" data-end="1787">Our <strong data-start="1472" data-end="1488">Buffer Tanks</strong> range includes compact Advantay Volumiser Buffer Tanks in 12, 18, 35 and 50 litre capacities, along with the Advantay 24 litre Heat Pump Buffer Tank. These smaller options can provide practical solutions where additional system volume is required without the footprint associated with larger tanks.</p> <p dir="auto" data-start="1789" data-end="2097">For larger installations, our Gledhill range includes SL Plus Multi Buffer, Indirect Buffer and Direct Buffer models from 90 litres through to 400 litres. We also stock Gledhill combined cylinder and buffer solutions, including the SL Plus CYL/BUF 200/70L and 300/70L models, with PP variants also available.</p> <p dir="auto" data-start="2099" data-end="2354">The <strong data-start="2103" data-end="2119">Buffer Tanks</strong> range is continually expanding as we add further products and configurations. This gives heating engineers and heat pump installers access to a growing selection of solutions for different system designs and installation requirements.</p> <p dir="auto" data-start="2356" data-end="2692">When selecting a buffer tank, installers should consider the system design, required capacity, connection arrangement and whether a direct, indirect, volumiser or combined cylinder and buffer solution is appropriate. Always check the manufacturer's specifications and installation requirements before selecting and installing a product.</p> Copyright 2026 MacDonald Plumbing & Heating Supplies en Fri, 09 Oct 2026 02:05:05 +0100 Fri, 09 Oct 2026 02:05:05 +0100 Fri, 09 Oct 2026 02:05:05 +0100 Advantay Heat Pump Buffer Tank 24 Litres Advantay Heat Pump Buffer Tank 24 Litres
