Product Description

Nowadays, due to the constant rise in oil and gas prices, there is an increasing need for energy efficient products that provide greater savings to users. Heat pumps offer a very efficient and cost-effective way to heat homes, replacingboilers that use gas or other fossil fuels.Most of homes use conventional and energy-inefficient systems such as gas boilers or furnace in order to produce domestic hot water. Main advantages of using a heat pump compared to a boiler:• Energy upgrading of buildings• Energy efficiency and operating cost reductions up to 70%• Return on investment approximately within 3 yearsMain advantages of using a heat pump compared to a central solar field:• Faster return of investment• Less space required• Less need for maintenance• Smaller volume of hot water storage tanks and hence less space for boiler roomsSolustions by Kolant DHP• Specifically designed for heating applications Nominal capacity from 3.5kW to 9kW• Maximum water temperature 60°C• Guaranteed operation without the performance reduction nor the temperature of the produced water, for ambient temperatures up to 43°C• Choice of anti-corrosion protection• External heat source control• Master-slave units factory-installed parallel operation• Pro Dialog Plus controller with liquid crystal display• Communication with MODBUS systems

Your best choice for domestic hot water
Domestic hot water heat pumps from Kolant intend to provide the most environmental solution for the generation ofdomestic hot water. By replacing the existed central hot water devices such as electric boilers, oil boilers etc, morethan 70% of the energy required for domestic hot water can be taken form renewable source instead of electricityheating or fossil fuel burning. This almighty heat pump also can be used as an energy saving heating device inmany places, e.g as a second heat source of a solar heating system.
