New stock is here

Along with new stock on hand, we have our first NS-300 production kits.

The NS-300 is our new unit for more demanding requirements. With a 300 litre tank, it is 50% bigger than our NS-15-20 200 litre flagship.

We will begin testing this unit as a swimming pool heater, with results available from October 2015.

We have 6 units for sale in September 2015.
