Nulite heat pump is a cutting edge technology product and lives up-to expectations. Nulite stands out for its top quality workmanship and design. With it's innovative builtin buffer tank it allows you to provide a steady flow of hot water for Heating and Domestic hot water. Featuring the new DC inverter compressor with R32 makes it Eco-friendly and very energy efficient. I recommend this product for the needs of the west of Ireland and places with climate like this, as the Stainless Steel case insures longevity of the craftsmanship it contains. I am now putting the Nulite R32 Polar X NL-B345II/R32 at the top my product portfolio I install.Keep up the good work.
