Frequently Asked Questions - EKEPHYHT35H DAIKIN
What is the Daikin EKEPHYHT35H used for?
The EKEPHYHT35H is a hydraulic module used as part of a Daikin Altherma air-to-water heat pump system. It manages water circulation, provides backup heating (if installed), and controls distribution to radiators or underfloor heating.
How do I install the EKEPHYHT35H hydraulic module?
Installation should be carried out by a certified technician. The module must be mounted on a solid wall or floor, connected to the outdoor unit and heating circuit, and filled with water. Follow the manual's safety instructions to ensure proper operation.
What type of refrigerant does it use?
The system uses R32 refrigerant, which is more environmentally friendly than older refrigerants. The exact amount and circuit details are listed on the outdoor unit's nameplate.
How often should I maintain the heat pump?
We recommend a professional maintenance check at least once a year. This includes cleaning hydraulic filters, inspecting the pump, checking pressure, and verifying safety devices. Regular maintenance extends system life and maintains efficiency.
Can I use it for both heating and domestic hot water?
Yes, when combined with a domestic hot water tank, the EKEPHYHT35H can manage both space heating and hot water production. The 3-way valve automatically switches between the two modes.
What is the maximum water temperature?
The maximum leaving water temperature is 65 °C. This is suitable for most radiators and can also serve underfloor heating with a mixing valve.
Is the system compatible with solar panels?
Yes, the controller can integrate with solar thermal systems or use surplus electricity from photovoltaic panels. Consult a qualified installer to configure the necessary inputs and settings.
What should I do if the pump is noisy?
A noisy pump often indicates air in the circuit or a blocked filter. Bleed the radiators and clean the hydraulic filter. If noise persists, contact a technician to check the pump settings or bearings.
How can I reduce the energy consumption?
Set an appropriate weather compensation curve to match water temperature to outdoor conditions. Use low-temperature emitters like underfloor heating, and ensure the system is properly insulated. Regular maintenance also keeps efficiency high.
Is the Daikin EKEPHYHT35H repairable?
Yes, its modular design allows replacement of key components like the pump, valves, expansion vessel, PCB, and sensors. Daikin provides spare parts and service manuals for qualified technicians.
