“I am two tanks” – that has been Haase’s slogan for decades. Our company is of course also developing further, the product range has been expanded considerably in recent years. Ultimately, however, everything revolves around containers made of GRP – the age and corrosion resistance of the material, the low weight, etc.
A Saxon manufacturer of precision castings made of stainless steel wanted to go new, sustainable ways when it came to the construction of an administration building when it came to heat supply. Steel processing generates very large amounts of waste heat, the sensible use of which can save a lot of money. In this case, excess heat from production is temporarily stored in two underground buffer tanks via the local heating network and used to heat the new building and to supply hot water.
The two underground hot water tanks were delivered and stored directly by Haase. 
The T330-143 undeground hot water tanks each have a volume of 14.3m³. 
The underground hot water tanks are insulated with PU foam and a waterproof cover made of GRP. 
The Haase T300 undeground hot water tanks can be used with an operating pressure of up to 3 bar and an operating temperature of up to 110 ° C.
