Wotech R290 Air to Water Heat Pump is specially developed with the most cutting-edge heat pump technology and modern design to meet stringent requirements for efficiency, stability and quietness. Not only does it use R290 green gas and inverter technology, but it is also rated with the A++ energy label. With a top energy rating of A+++, the unit is energy efficient and can significantly reduce the user's energy bill.
R290 is one of the best refrigerants available for mass production upto now: Negligible Global Warming Potential (GWP) and degradation time is considered in months: Zero ozone layer depletion potential (ODP): Permanent green: Less load for the same performance; Low energy consumption and higher efficiency.
Thanks to the use of R290, Wotech R290 air to water heat pump is now not only the best solution for new buildings, but also possible to fit the retrofit market by lifting up maximum heating temperature to 70°C. With good performance in this range of water temperatures, it is now possible to replace an old gas/oil boiler with an air-to-water heat pump unit without changing the existing heating distribution system or even the old radiators inside.
DC inverter technology enables the heat pump to adjust its frequencyaccording to real heating requirement. With this technology, Wotech R32/R290 air to water heat pump achieves an energy level of A+++ according to Erp directive.
The split system design of the heat pump, consisting of an indoor and outdoor unit, requires specialized installation by an installer qualified to work with refrigerant gases. The advantage of this solution is that there is no risk of freezing of the heating medium in case of power failure. Unlike monoblock pumps, the unit outside the building uses a non-freezing refrigerant.
• More flexibility thanks to two control zones
• Independent control of underfloor heating and radiator heating temperature
• No need to purchase an extension module for second heating system
Preheat your home floor by activating the Floor Preheating function to prevent possible floor damage. The Floor Preheating function gradually increases the heating temperature of the floor coils.In addition to protecting the installation, the Floor Drying Up function ensures the heat pump operates optimally and effectively by removing any residual moisture from newly installed floor coils.
You can choose different climate correlation curves or your own customised curve. Once the curve is selected, the unit sets the outlet water temperature automatically according to the outdoor ambient air temperature.
Maintain pristine quality of the water tank's DHW and eliminate germs and bacteria by increasing the temperature of the water in it up to 65C.
