Envirogreen™ Combi HE

The Firebird HVO ready, Combi (combination) oil boiler which is manufactured in Ireland is an instant domestic water heater and a central heating boiler combined. Water is heated directly via a thermal store when a tap is turned on, saving not only on cost, but also on the space required for a hot water storage tank. Providing instant access to hot water, this type of boiler is particularly suited to smaller households with one bathroom and shower/ensuite.

  • Single high efficiency Grundfos circulating pump.
  • Rapid re-heat after hot water draw-off.
  • PCB controller with highly accurate thermistors.
  • Fully insulated and acoustically designed for ultra quiet operation.
  • No flow switch – water flow is electronically detected.
  • Low pressure switch protects boiler in the unlikely event of system water loss.
  • Robust “positive shut-off” filling loop and check valve.
  • Multi-directional flue options.
  • Easy to install & service.
  • High performance low NOx Elco burner.
  • Three models available in outputs from 12kW to 35kW.
