Hotels and Resorts in Nepal
Hot water availability is one of the most critical factors in hotel guest satisfaction reviews in Nepal. A single hot water failure during peak morning hours can result in multiple negative reviews. The KX180S EP-2/A, with its built-in water-return system and 18kW of continuous heating output, ensures that hot water is always available at every tap and shower — even during the busiest check-out morning or a cold winter night in Kathmandu, Pokhara, or Chitwan.
Multiple KX-series units can also be cascaded together for larger properties of 60 rooms or more, giving you modular scalability without requiring a complete system overhaul as your business grows.
Hospitals and Healthcare Facilities
Hospitals require hot water that meets hygiene standards consistently and reliably. The KX180S EP-2/A delivers water at up to 55°C, which is sufficient for most healthcare hot water requirements. Its double-wall condenser design also ensures that the water circuit is completely isolated from the refrigerant, maintaining water purity — a critical factor in medical environments.
Pashmina Factories, Laundries, and Dairies
Industrial applications in Nepal — particularly Pashmina washing, commercial laundry, and dairy processing — require large volumes of hot water at sustained temperatures. The KX180S EP-2/A’s 18kW continuous output, combined with appropriately sized storage tanks, can feed these processes reliably while cutting the diesel or LPG costs that currently represent a major operational expense for these facilities.

Installation of the KX180S EP-2/A in Nepal
Proper installation is critical to getting the maximum performance and lifespan from your KX180S EP-2/A. At Nepal ecogreen, our trained and experienced technicians handle every aspect of the installation process — from site assessment to commissioning.
Site Assessment
Before installation, our technical team visits your property to assess daily hot water demand, existing tank capacity and condition, available space for the outdoor unit, electrical supply (380V three-phase), water source quality, and plumbing configuration. This assessment ensures the KX180S EP-2/A is correctly matched to your requirements.
Installation Process
The single-package design of the KX180S EP-2/A simplifies installation significantly compared to split systems. Our typical installation involves positioning the unit on a structurally sound surface (rooftop, ground slab, or plant room), connecting to the existing hot water storage tank, connecting the three-phase power supply, setting up the control system and cloud monitoring, and commissioning and test-running the system.
Most standard installations are completed within one to two days, minimising disruption to your facility’s operations.
Compatibility with Existing Systems
The KX180S EP-2/A integrates smoothly with most existing hot water storage tanks and plumbing configurations. If your existing tank is in good condition and appropriately sized, our team can often retain it, reducing overall installation cost. We also advise on optimal tank sizing to maximise the heat pump’s efficiency and ensure there is always sufficient hot water buffer for peak demand periods.
Yes — and it is actually one of the most efficient combinations possible in Nepal. Solar collectors can pre-heat the water entering the heat pump storage tank, reducing the temperature differential the heat pump needs to overcome. This pushes the effective COP even higher — sometimes exceeding 5.0 — and reduces electricity consumption further. Our team can design this integrated system for your property.
