Heat Pump Water Heaters in Nepal: 2026 Prices and Models

How to choose a heat pump water heater in Nepal

A heat pump works like an air conditioner in reverse: a compressor and refrigerant move heat from outdoor air into water. Because it moves heat instead of making it, it delivers several units of heat for each unit of electricity. Our ULTRA 5KW domestic unit, for example, gives 5000W of heat output from 1210W of input power, around four times what a plain electric element would give for the same electricity.

A heat pump makes more sense than solar when you need hot water every hour regardless of weather, when roof space is limited or shaded, or when demand is high and concentrated in the morning and evening, as in hotels and hostels. It also suits the Terai and valley areas where winter fog can block the sun for days. Many buildings pair both: solar for daytime gain and a heat pump for reliable top-up.

• Size by hot water output per hour (L/h), not just kW: match it to peak demand such as morning showers
• Check your supply: our 5KW, 7KW and 10KW units run on single-phase 220V; the 18KW, 36KW and pool models need 380V three-phase
• Check the operating range: listed models work down to -7°C ambient, which covers most of Nepal outside the high mountains
• Leave open space around the outdoor unit for airflow, and consider noise near bedrooms
• For pools, size by pool volume and how warm you want the water, and confirm the water flow rate of your filtration pump

Domestic, commercial and swimming pool models compared

For homes, the ULTRA Heat Pump Water Heater 1.8KW is an all-in-one unit with an integrated 200L tank, 2000W auxiliary heater and a maximum water temperature of 70°C. The ULTRA 5KW and 7KW domestic units are air-to-water heat pumps producing 107L/h and 150L/h of hot water at a rated 55°C, suited to bathrooms, kitchens and whole-house use.

For commercial buildings, the 10KW unit (JDLKFXRS-10I/S2H) produces 215L/h on a 220V supply, the 18KW unit (UDLKFXRS-18II/S2) produces 390L/h, and the 36KW unit produces 780L/h on three-phase power. A 25KW commercial model fills the gap between them for hotels, hospitals and hostels that need continuous operation.

The ULTRA Swimming Pool heat pump is rated at 20KW heating and 12.8KW cooling with a rated COP of 6.35, so it can keep pool water comfortable well beyond the summer months for hotels, resorts and private pools.

What drives heat pump price in Nepal

Price rises mainly with heating capacity. The domestic 5KW model sits at the low end, while the 36KW commercial unit sits at the top because it has larger compressors, heat exchangers and three-phase electrics to deliver several times the hourly hot water output.

Other factors are whether a storage tank is built in (as on the 1.8KW 200L model), the refrigerant and compressor design, maximum water temperature, noise level, and special functions such as the heating and cooling modes on the pool heat pump. Installation cost depends on piping runs, tank size, electrical work and whether a three-phase connection is already available.

Running cost compared with an electric geyser

A standard electric geyser turns each unit of electricity into roughly one unit of heat. Based on the listed input and output figures, our domestic and commercial heat pumps deliver about four units of heat per unit of electricity under rated conditions, and the pool model lists a COP of 6.35. Actual savings depend on air temperature, water temperature setting and daily use, so ask us for an estimate based on your consumption.

Installation and after-sales from Mega Solar Energy

Our team surveys the site, recommends a capacity, plans the outdoor unit position, piping and storage tank, and coordinates electrical requirements before installation. We deliver and install across Nepal, including hotels and resorts outside Kathmandu Valley.

After handover we provide servicing and troubleshooting. Warranty terms are confirmed for each model at the time of purchase. Routine care is simple: keep the air coil clear of dust and leaves, keep the area around the unit open, and have the system checked periodically, particularly on commercial units running long hours.
