Description
The Grant Vortex Pro outdoor combination oil boiler features internal frost protection, a 24 litre expansion vessel, neon diagnostic indicators and a factory-fitted condensate trap. With larger than normal heat exchangers, the hot water performance of this high-efficiency combi boiler is vastly increased. The two very accurate electronic temperature controls allow the boiler to operate in condensing mode in central heating so instant hot water production can be maintained.
KEY FEATURES
- Award winning range
- Compact design
- Fitted with a low NOx Riello burner
- High quality external powder coated finish
- 89.5% Gross SAP2009 annual efficiency making the range one of the most efficient boilers on the market.
- Unlike traditional oil-fired boilers the Grant Vortex condensing boiler has a built-in stainless-steel heat exchanger incorporating our unique turbulator baffle system which cools the gases to a point where the latent heat, normally lost to the atmosphere through the flue, can be usefully extracted. The additional energy recovered enables the boiler to operate continuously at much higher efficiency levels, resulting in lower heating and hot water running costs.
- Exceptionally quiet operation
