An Xtra boost for hot water efficiency

An Xtra boost for hot water efficiency

  • New boiler flue gas heat recovery unit, the Greenstar Xtra harnesses waste energy to help properties achieve higher SAP ratings.
  • Easy to fit with a flexible and compact design.
  • Delivers efficiency without the need to install more costly renewable technologies or large amounts of insulation.

We’ve launched a brand new boiler flue gas heat recovery unit, designed to help housebuilders and public sector providers, achieve the best possible hot water efficiency levels.

The Greenstar Xtra unit connects directly to the flue of the boiler and uses a highly efficient plate heat exchanger, to extract residual energy from waste gases. This energy is then used to pre-warm the incoming mains water which feeds the combi boiler – reducing the overall amount of gas needed to heat the water to the required temperature.

Developed to help properties achieve highest possible SAP ratings, the unit not only limits gas consumption and CO2 emissions, it also helps to reduce utility bills by delivering added hot water efficiency.

The compact design of the Greenstar Xtra ensures ease of siting and the flue options of both 60/100mm and 100/125mm diameters result in flexible installation options for installers. In addition, and unlike other heat recovery systems, the unit does not require a blending valve or an additional mounting plate meaning that the time taken to fit the device, and associated labour costs, are kept to a minimum.

Available now, the Greenstar Xtra replaces our Greenstar Ecoflo, and is compatible with the Greenstar i, Greenstar Si and Greenstar CDi Compact combi boilers.
