HG Series Cylinders – Designed by Heat Geek
Introducing the HG Series
Designed by Heat Geek | Made by Newark Cylinders
Bespoke hot water cylinder manufacturer, Newark Cylinders, have launched the HG series – a range of ultra-high efficiency cylinders designed by leading heating experts, Heat Geek.
The HG Series has been designed to be the most efficient hot water cylinder available in the UK. This is being continuously and independently measured by the live performance data that is available at heatpumpmonitor.org.
All HG Series Models include a 6.0m² coil (except the HG150A which has a 4.0m² coil, due to insufficient space) as well as other features which are specifically designed to optimise stratification.
They are also designed to maximise the effect of what Heat Geek calls “the heat source saturation point”. This means that heat pumps will heat the hot water with a much lower flow temperature, rapidly increasing their efficiency. If used with a gas boiler this will mean the boiler will either completely condense in hot water, (increasing gas efficiency by over 10%, if controlled as Heat Geek suggest), or give the fastest recovery time currently available on the market.
The HG Series A models are available from 150L to 450L. The HG Series B models are designed for installation spaces with restricted height and are available in two sizes; 230L and 300L. Furthermore, all HG Series models include a steel mounting plate, and 90° ergonomic Carrying Handles.
