RecoFLUE

Passive flue gas heat recovery device

  • Helps improve the energy rating of a new build property by up to 3%
  • Improves Domestic Hot Water efficiency by using latent heat within flue gas to pre-heat incoming mains cold water.
  • No need for blending valve or expansion vessel in most system designs.
  • Compatible with both horizontal and vertical flues.
  • Fitted independently of boiler.

Overview

To further improve the efficiency of your new Vaillant ecoTEC boiler, you may choose to add a recoFLUE flue heat recovery device, which is an appliance that can simply be installed on top of your boiler. This Passive Flue Gas Heat Recovery Device (PFGHRD) captures waste energy from flue gases and subsequently returns this recovered energy to improve the efficiency of hot water production.

Why install recoFLUE?

A recoFLUE installation can improve the efficiency of your hot water delivery by up to 40%, which can in turn help to reduce your overall fuel bills.

How does it work?

  1. recoFLUE can be attached to the flue outlet of a condensing combination boiler
  2. Domestic Hot Water is pre-heated through the device
  3. Heat is transferred via a condensate store (water store) and/or heat exchanger
  4. Pre-heating reduces the amount of gas used for hot water

Which boilers is it suitable for?

Both vertical and horizontal flues and can be used with our ecoTEC plus and pro combination ranges to create an even more efficient, cost-effective system.
