The GX100 Heat Bank Thermal Store provides both mains pressure, temperature controlled, hot water, at up to 40 litres per minute, and 10 bar pressure.  The store also provides fully pumped central heating.

The store is very small, capable of hiding under a kitchen worktop, and has very low standing heat losses.  It can however, deliver a full bath in under 4 minutes, with hot water to spare, and follow up with another bath within 15 minutes of the first.  Also, radiators can be brought up to full temperature in under a minute of turning the heating on.

Mechanical installation consists of simple push fit-pipework connections, and the only site wiring required is connection to the mains electrical supply, boiler and room thermostat.  Being a fully vented thermal store, the system can be installed by installers not qualified to install unvented systems. 

As standard, the store is on 24hrs a day, with the room thermostat being the only control the householder need use.  A backup 3kW immersion heater provides backup central heating and hot water in case of boiler failure.  All components are tamperproof.
