The GXV Xcel a superb all-round performance system, originally designed as a compact, high output hot water and heating system for council properties. To obtain 100% useful input from the boiler, the store is heated directly by the boiler - no coils. A feed and expansion tank must be fitted above the highest point in the primary system. The main advantages of the system are...
No Motorised Valves for either hot water or heating - more reliable & easier to service.
Very rapid recovery of store - hot water in under 3 minutes from cold.
Large volumes of hot water from a small store.
Maintains condensing boilers in condensing mode. 
Ability to bring central heating up to temperature extremely quickly (store recovered).
Store acts as an ideal air separator.
The flow to the boiler [20] can be run through the Aga cooker prior to the boiler.    This will allow both heat sources to be used simultaneously to recover the store using a single set of flow and return pipework.

The DanfossTP5E RF room stat communicates with the RX1 receiver (fitted and wired to the Heat Bank Thermal Store) using a digital radio signal. The room stat runs for two years of two standard AA batteries, requires absolutely no wiring, and can be easy positioned (or re-positioned) to suit. Another huge benefit, is the ability of the room stat to heat the property to different temperatures, at different times. This allows large energy savings to be made, while increasing comfort levels.

 

The unit is fitted with one heat exchanger, capable of delivering 30 litres/minute @45°C (80°C storage). The graphs shown the domestic hot water output that can be achieved for various storage temperatures.

  

A Mains Water Isolating Lever Valve must be fitted within the cylinder cupboard, in clear view and easily accessible. A Strainer (supplied loose) must also be fitted, down stream of the isolating valve, to protect the flow switch [4].
It is advised that the mains water is tested for hardness. In areas of hard water, we advise the use of a scale inhibitor.
It is important that SENTINEL X100 Inhibitor is used to protect the Heat Bank Thermal Store.  Use 1 litre per 100 litres of stored water. A suitable anti-freeze, such as X500, should also be added when there is a chance that the unit will be left filled and unheated in freezing conditions.
