Different accumulator types and sizes can be connected
Can be used in niches because of the forward-pointing connections
Tank temperatures can be easily read off the tank
Can be combined with fresh water module FRIWA30
Best thermal insulation due to 100 mm fleece insulation
Unique, patented connection between two buffer tanks
Covers as standard to reduce radiation
Long service life thanks to quality steel and powder coating
Resistant polystyrene jacket
Fleece insulation
Up to 36 % less heat loss compared with expanded foam insulation. Made of 70 % recycled material, AccuWIN already satisfies future EU requirements.
Indicating thermometer
3 indicating thermometers allow the buffer tank temperatures to be easily read off at the top, middle and bottom.
6/4" connections
Requires little space and can be used in niches because of the forward-pointing connections.
Hooked strip
Quick, easy installation and a clean look since the cable duct has several functions.
Connections pulled up and down
The best use of energy is gained by taking out the heating water at its highest temperature (top), and also loading the bottom part which is not normally used.
Small, but highly efficientPerfect heat management and best possible use of energy are the priorities of the new AccuWIN heat accumulator range.
With innovative combination and loading technology, Windhager will be able to utilise stored heat even more efficiently in future. To this end, the buffer tanks are connected both parallel and diagonally. This means the solar yield is significantly greater than in conventional solutions, and above all in buffer cascades with only one solar accumulator.
