Heat pumps

Like solar collectors, heat pumps has a variable inlet temperature. Therfore, StratiFlex™ can be installed to avoid mixing of the different thermal layers during a heat pump charge, and achieve superior thermal stratification in the hot water storage tank.

Solar inlet

As the inlet from solar collectors has a variable temperature, our patented product – StratiFlex™ – is an excellent tool, to avoid mixing of the different thermal layers during a solar charge, and achieve superior thermal stratification in the hot water storage tank.

Space heating – return

Space heating from any heat source (oil, pellets, district heating, geothermal etc.) does not necessarily have a variable return temperature.  However, the return water should never be applied to the top of the tank. The specific thermal layer in the tank, which has the same temperature as the return from space heating however, will be present in variable heights in the tank. A StratiFlex™ installed will make sure that the return water always finds its way to the correct thermal level.

Domestic hot water circulation – return

Larger supply networks (e.g. apartment buildings) will need circulation of the domestic hot water in order to offer the users furthest away from the heat source an acceptable temperature level. The return water will have same characteristics a needs for stratification as the ones mentioned for space heating returns.

Electrical heated tanks

Installing a stratifier in an electrical heated tank, enables partial heating (the top) of the tank. Conventional electrical heated tanks can only be heated in full, as the heating occurs from the bottom of the tank. In areas with peak/ off peak pricing on electricity, this help consumers save money on electricity, by enabling optimization of consumption of electricity. In the future, smart grid and intelligent house control will lead to that electrical heated tanks are to operate with much less stand-by volume, which is only possible, if it is possible to make small charges of the top of the tank during peak pricing period, and move the larger charges to the off peak periods. The StratiFlex™ enables heating from the top of an electrical heated tank.
