Mikrofill’s hot water loading systems have been developed specifically to meet the demands of modern commercial buildings. The Extreme is a domestic hot water generator that combines the advantages of both an instantaneous hot water heater and a storage system, creating perfect harmony between a condensing boiler and a hot water cylinder.

Available in 200, 300 and 500 litre versions

The Extreme loading system addresses and overcomes all of the disadvantages of the traditional coil type cylinder, whilst remaining simple and straightforward to install. In addition the operating principle ensures the efficiency of a condensing boiler is optimised during the production of hot water.

The Extreme produces exceptional flow rates in excess of 2500 litres per hour at 60⁰C.

Mikrofill’s uncompromising approach to quality materials, design flexibility and engineering excellence has resulted in the Extreme, the new standard in hot water generation.

The WRAS approved Mikrofill 3 is a wall mounted pressurisation unit that has the ability to fill directly from the mains/boosted water supply any LPHW or CHW system from empty.

In addition the Mikrofill 3 incorporates Fluid Risk Category 4 backflow prevention and comprehensive electronic pressure management.

Unlike “pump type” pressurisation units the Mikrofill 3 is designed to be connected directly to a buildings incoming mains/boosted water supply and fill a heating or chilled water system without the use of a pump.

The Mikrofill 3 utilises the energy already generated by the mains water or boosted water supply and does not contain an RPZ valve.

Pre – commissioned packages are available, which include the Mikrofill 3 with appropriately sized vessels and service drain valves.
