Hot Water Heat Pumps
Energy-Efficient Heating for Residential & Commercial Applications
At Specific Technical Service (STS), we provide high-performance Hot Water Heat Pumps engineered to deliver reliable and eco-friendly hot water solutions for both domestic and commercial needs. Using advanced heat pump technology, our systems offer a highly efficient, low-cost alternative to traditional electric or gas water heaters.

How It Works
Our heat pumps harness renewable energy from ambient air, converting it into usable heat through a refrigerant cycle. This upgraded heat is then transferred into water, delivering hot water with minimal energy consumption.
Energy Efficiency at Its Best
While conventional electric heaters use 1 kW of power to produce 1 kW of heat, our heat pumps can deliver up to 3 kW of hot water using just 1 kW of electricity—making them three times more efficient than traditional systems.
