Heating with innovation

ACV’s innovative tank-in-tank technology has seen them become a market leading cylinder manufacturer.

Within an ACV hot water cylinder central heating water heats a second vessel within the cylinder housing the domestic hot water. This vessel acts as a heat exchanger, with the large surface area ensuring rapid domestic hot water recovery.

This system also discourages limescale and bacterial build up within the cylinder, as unlike traditional coiled models, all the water within an ACV cylinders heated at the same rate, making for more hygienic water heating.

ACV’s fast recovery cylinders come with a 3 kW immersion heater as standard and are the perfect partner for renewable heating systems such as solar thermal, air source heat pumps, ground source heat pumps, wood burning boilers and more besides.

ACV also produces combination boilers which work on the same unique tank-in tank-technology.

ACV’s range of commercial and domestic products includes:

• Fast recovery hot water cylinders
• Gas fired condensing combination and system boilers
• High efficiency boilers (oil, gas, LPG or bio-diesel fired)
• Electric boilers
• Compact steel boilers

ACV have been designing and manufacturing ground breaking water heating solutions since 1922 and their catalogue contains some of the most progressive and innovative boilers and hot water cylinders on the market.
