Increased DHW delivery rates and space saving

Complementing Johnson and Starley's latest RenoXtra high efficiency combination boiler, a new Hiflow thermal store module or kit can now be added to the heating system.

The benefit of the RenoXtra with Hiflow is the provision of a higher flow rate of DHW at 35C rise for a considerably lower gas input, typically 6kW from the boiler.

The Hiflow module is compact and capable of being installed under a worktop.

The Hiflow is comprised of al thermal store cylinder of either 25 or 50 litres.

This can be provided in a pre-plumbed and wired cabinet module or in kit form.

The Hiflow module is connected to the RenoXtra that both pre-heats the DHW supply and provides the heat input to the Hiflow thermal store via its programmable controls.

An optional secondary return can be connected to the 50-litre model.

The RenoXtra with Hiflow system works in two possible modes, dependent upon the hot water demand.

When demand is within the capabilities of the RenoXtra 30 or 37 kW combination boiler the water is delivered in a traditional 'combi fashion'.

When increased delivery rates of DHW is required the Hiflow module can be activated on demand, either manually or by timer control, boosting performance for peak demand periods.

When charged the RenoXtra with Hiflow thermal store system will deliver up to 20 litres per minute for 10 minutes with a recovery time of only 6 minutes.

The energy and carbon saving capability of the system, which, in combination with enhanced DHW delivery rates is impressive.

The integrated space saving design of the High delivery system open up new opportunities for better space utilisation in new build houses.

The existing RENO HE30C and 37C combination boilers can be used in conjunction with the Hiflow Thermal Store but without the advantages of the RenoXtra gas saver module.

This may be suitable where ceiling height restrictions exist.
