The Duratech Dura Plus Range of Swimming Pool Heat Pumps provide enhanced performance over the standard Dura range. (the differences from the standard Duratech range are highlighted in bold) High efficiency by using R410a refrigerent gas COP (Coefficient of Performance) of up to 6 Operate down to -10C degrees Can Heat and Cool the water Dual speed fan for extra energy efficiency and reduced noise Suitable for Koi ponds as well as swimming pools Hot gas defrost cycle to allow operation at lower temperatures Titanium heat exchanger - The use of titanium for the heat exchanger leads to efficient heat transfer without any dangers of corrosion. Digital control panel on all models Green UK & European compliant extra efficient refrigerant gas (R410a) Plastic ABS corrosion resistant casing on 7kw, 10kw, 14kw, 19kw. Stainless steel casing on 22kw and 30kw units Refrigerant gas pressure gauge Delivery in 1-week from order 2-Year parts and labour warranty Designed & Built For Long Life & Reliability Using high quality materials in the build of the Duratech Heat Pump and "Duranium®", an advanced version of Titanium, for the heat exchanger means it is practically "Bullet-Proof" to erosion from Chlorine, Bromine or Salt in the water. Also, the "Duranium®" heat exchanger is oversized to improve efficiency and make the Duratech Heat Pump even more cost effective and great value for money.
