This Agentis External Heat Only from Warmflow is a regular oil boiler with an output of 21kW. Although it is a compact and discreet boiler, it’s still a very capable and extremely powerful model. As a regular boiler it will provide heat for central heating but should be installed alongside a hot water cylinder in order to provide domestic hot water. The Agentis boiler features Warmflow’s unique, patented high efficiency stainless steel heat exchanger technology as well as the latest Riello low NOx burner technology. It has been designed to be installed outside the home. The boiler’s compact size and sleek green casing makes the Warmflow Agentis the ideal solution for all outdoor installations. This range of oil boilers is amongst the most efficient in the UK reaching efficiency levels in excess of 90%, which should lead to cheaper heating bills and reduced carbon emissions for many households. This boiler is also available in 26kW, 33kW, and 44kW.
