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 a Mixcall III Thermostatic Blending Valve, to control the hot water temperature, and prevent scalding.  The graph shows the pressure drop across the valve for various hot water flow rates.

The Valve is adjustable from 27°C to 67°C, and has a lockable head.

The unit is fitted with an Integral Overflow Chamber [8], which traps small volumes of water discharged as a result of overfilling. Water in the chamber can be drained off via the Overfill Drain Cock [66]. The unit MUST be watched during filling as excessive overfilling will result in over-spill onto the floor.
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.

The Vokera Mynute is compact in design when compared to most traditional wall hung boilers. The big advantage is that all the associated components needed for a traditional system are contained within the boiler case. The Mynute covers outputs from 5.6 to 28 kW.

  Expansion vessel, pump, safety valve built in.
  Installation time reduced - along with materials required - resulting in substantial cost saving.
  Simplified servicing and maintenance
  Frees loft space of feed and expansi
