The Vaillant ecoTEC Plus 937 HE Power Store is a wall mounted combi boiler that features a hot water store that copes with high demands for hot water better than an ordinary combi boiler.

This type of boiler is ideally suited to properties where the demand for hot water may be high at certain times. A good example of the size of property this boiler would suit is a 3 to 4 bedroom house with one bathroom and an ensuite. The Vaillant ecoTEC Plus 937 HE Power Store achieves this performance with a 15 litre water store and 1 litre expansion vessel fitted in to the boiler casing.
