Peace of mind total solution provider
The building withstood the test of time with the loving care from the operator. However, the heavy duty heating machine require technical supports & compatible parts from manufacturer. Hotel management are facing the struggle where the original service provider and equipment maker unable to extend their continued service, where Waterco, a local manufacturing company with competent engineers set on retrofitting the failure unit with its expansive heating solution.

Engineering a more sustainable world

Through years of research and experience in manufacturing, Waterco’s HWS (hot water system) tailored in providing hot water efficiently with COP (coefficient of performance) up to 6.0 times the original power input.

A 40kWh at peak COP of 6.0 merely consume 6.67kWh of electricity.

An opportunity to decarbonize for greener environment
Unlike traditional electric heating element where there is no COP, the consumption of electricity of HWS heat pump is greatly reduced. Overall cost of electrical component can be lowered due to lower amperage requirement on input power. The zero carbon emission during the heating process is ideal in preserving the environment.


A double-edged advantages

Heat pump heating machine will produce cool air as by-product, this can be channel to cooling tower to improve its cooling capacity.

The reason being heat from ambient air is extracted, thus resulting cooler air being expel from the system. Unlike gas-fired heater, heat pump operation does not involve combustion process, air is clean and no waste gas exhaust.
