Gas Boilers
ACV is always at the forefront of developing to satisfy hot water and heating needs which have changed dramatically over the last 30 years, ACV introduced the first storage combination boiler in the 1970's - the Delta was ahead of it time and the first in its class. Due to ACV's unique stainless steel Tank-in-Tank technology, the boiler and storage cylinder could be combined together in a single shell - transfer losses between the two were eliminated and performance (flow rates and recovery times) improved as a result.
The ACV MeatMaster 35TC With the high levels of building insulation now in place in most properties, the requirements for heating output are reducing - and this trend is set to continue with some experts predicting a drop in the boiler load due to heating from around 75% to as low as 45%. At the same time, hot water usage is increasing year-by year as demand rises for luxury bathing facilities such as high performance showers and spa baths. If hot water demand has risen to 55% of the boiler load, the natural next step is to gain as much efficiency in hot water mode as possible.
To meet these high hot water requirements, larger properties normally require a separate boiler and cylinder or a storage combination boiler. To achieve efficency it is best to have the boiler and cylinder as close as possible.Efficiency also usually means using a condensing boiler, but typically condensing combination boilers only actually condense whilst working in heating mode and efficency in hot water in a variety of condensing combination boilers varies considerably from boiler to boiler.
