Heat Geek Mini Store

Renewable energy sources require somewhere to store hot water, due to the lack of extreme power density of gas, resulting in water having to heat up slowly. However, the problem is that 22 million homes in the UK either don’t have a hot water storage cylinder or don’t have the space available to them. This results in homeowners struggling to decarbonise their heating.

As a solution, Newark Cylinders has launched the Heat Geek Mini Store. Designed by leading heating experts, Heat Geek, the Heat Geek Mini Store is a range of super-compact, highly efficient, Shell & Tube Heat Exchangers.

The Heat Geek Mini Store is designed to be a compact hot water storage solution and is around a quarter to a third of the size of conventional hot water cylinders. With sizes ranging from 60L to 130L, the Mini Store offers installers and homeowners a highly viable backup option for decarbonising homes. Furthermore, the Mini Store can make gas boilers to be their most efficient.

Mini Store Benefits

  • Operating with flow temperatures as low as 40-45°C, they are ideal for use with Heat Pumps.
  • Very high hot water flow rates can be achieved (compared to a standard combination boiler), allowing up to three showers to be run simultaneously.
  • Their recharge times are unmatched by any standardised hot water storage solution currently available.
  • They are so compact that they’ll fit into almost any property – in kitchen cupboards, small airing cupboards, under-stairs cupboards, low roof spaces, or anywhere that you have a small amount of spare room. They can even be laid horizontally, and/or wall-mounted for extra versatility. They are also reversible, in that they can be installed upside-down, in case swapping the positions of the coil connections with the heat source flow & return connections proves to make piping them up easier.
