Heat pumps that work where Sri Lanka actually gets hot

Air-source heat pumps deliver 3-5× the efficiency of resistance heating or gas boilers — for hotel sanitary hot water, swimming pools, commercial laundry pre-heat, and villa hydronics. Konnen and Hitachi, sized to tropical loads.

Four ways we deploy them

Where heat pumps earn their keep

Anywhere you currently burn diesel, LPG or kilowatts of resistance heat to make hot water, a heat pump pays back in 2-4 years.

Hotel sanitary hot water

60-80°C output for guest bathrooms, kitchens and back-of-house. Replaces gas/diesel boilers and electric calorifiers.

Swimming pool & spa heating

Titanium tube exchanger handles chlorinated and saline water. Year-round 28-30°C pool temperature.

Commercial laundry pre-heat

R32 / R134a high-temperature units pre-heat wash water to 60-80°C, slashing diesel boiler load by 60-70%.

Villa heating + cooling + DHW

Single monobloc, 5-20 kW range. Hydronic floor cooling/heating plus domestic hot water from one outdoor unit.

Konnen heat pumps

Konnen — Engineered for tropical and commercial scale

Chinese precision manufacturing under Zhejiang CEN — 25 years building heat pumps for international export markets. Every model lab-validated to +52°C ambient, with blue-coated evaporators for coastal corrosion resistance.

Positioning matrix

When to specify which brand

Both brands are genuinely good. The right choice depends on the project's procurement profile, brand requirements and lifecycle expectations.

Choose Konnen when…

  • Price-led project with strict capex ceiling
  • Pool or spa heating is the primary load
  • Large commercial DHW plant (5-200 kW)
  • Saltwater or coastal corrosion is a concern
  • Fast lead time matters more than brand prestige

Choose Hitachi when…

  • Consultant-specified or tender-mandated
  • Brand-name hotel chain (Hyatt, Shangri-La, etc.)
  • Premium villa or low dB(A) requirement
  • 10-year compressor warranty is critical
  • Full-building integration with Hitachi VRF

We supply both. NativeWay engineers will pick the right brand and model for your loads, lifecycle cost, and procurement timeline.

Heat pump vs boiler vs resistance

Why heat pumps win on every axis

A heat pump moves heat rather than making it. That single physical reality changes the economics of hot water completely.

1

3-5× efficiency

1 kWh of electricity in → 3-5 kWh of heat out. Resistance heating tops out at 1:1. Boilers lose 10-25% up the flue.

2

Lower OPEX

Vs LPG and diesel boilers — typical 60-70% savings on hot water energy cost. Payback 2-4 years on commercial loads.

3

Lower emissions

No on-site combustion. No flue. No fuel storage. No carbon monoxide risk. Aligns with hotel sustainability reporting.

4

Future-proof

R32 low-GWP refrigerant. As the SL and BD grids decarbonise, every kWh you draw gets cleaner — without retrofitting plant.
