Domestic Hot water heat pumps

Vindsol residential / Domestic heat pump are the most efficient system for hot water generation in a environmental friendly way up-to 55 deg without using any auxiliary heating from electrical element. The residential heat pump range was developed for easy retrofit installation for any existing hot water geyser as well as new installations. The installation, methodology has been developed to be complete non-intrusive

Vindsol domestic heat pumps is of :

  • Monoblock type: compact and efficient heat system with built-in heat exchanger (Copper Tube in tube ) and circulating pump in the outdoor unit

These two models mean that you’re able to take advantage of cost saving hot water heating in any environment, day or night. The heat pumps are micro-computer controlled with a timer function, allowing them to automatically and efficiently regulate the water temperature.

Users of Vindsol residential heat pump can therefore: rest assured that their investment will benefit them in savings money as well as energy.

Features

User Friendly Installation and low maintenance

Designed for easy access and simple installation. Maintenance for the equipment is almost non -existent providing maximum safety and security.

Efficient any weather performance

Efficient performance day or night or in any weather. So irrespective of the weather outside you can always have hot water at your disposal.

Power of Heat pump Specific Rotary Compressor

New generation Rotary compressor designed especially for heat pump, which has a higher condensing temp. when compared to regular AC compressor.

Advanced Controller functions

Next Gen advanced fully automatic heat pump controller with advanced energy savings functions & full system protection.

WIFI function

The controller has built-in WIFI functionality with App for easy operation, you can set the desired temp and switch on / off the system.

Quiet Operation

Unlike regular heat pump, it doesn’t have any moving apart from compressor it is extremely silent and doesn’t bother you.

Benefits

Constant hot water supply

of 55-60 deg irrespective of the season outside.

All Seasons working

Heat pumps can operate all day every day all season. Including overcast & rainy days.

Energy saving of 60-75%

is outstanding compared to conventional electrical heating systems with quick payback period.

Environmental protection

Eco friendly refrigerants emit much lower Co2 footprint than other heating equipment’s without burning any fossil fuels.

Very low maintenance

Long service life and low maintenance cost, with stable equipment performance Its service life can reach over 10-15 years

Convenient and Easy installation

Using our qualified service and installation teams. It can be installed in any place, such as roof and floor etc.

HIGH reliability

Designed specifically for the outlasting harsh climatic conditions and last longer than other heating methods.

Self-Diagnostic function

Errors are automatically detected by the system with specific code. Each code designate an error for easy understanding and troubleshooting.

Key Components

SCROLL COMPRESSOR

Highest durable and reliable compressor in the market Fully protected (High/low temp. and pressure. over current, phase protection) Anti liquid impact.

4 WAY REVERSING VALVE

Design ensures instantaneous changeover with minimal pressure drop. The valves are equipped with a mechanism that prevents incomplete changeover

ELECTRONIC EXPANSION VALVE

Effectively controls the temperature & regulates optimum refrigerant flow for best in class C.O.P. Better operating conditions means less faults and consequently a reduction in maintenance costs.

REFRIGERANT

Various option of Refrigerant liquid as per application that is environmentally friendly, non flammable and non toxic

HYDROPHILIC FINNED EVAPORATOR

The hydrophilic coated finned evaporator with enhanced frosting and corrosion resistance. The corrugated louvered fin extend heat exchanging surface, thereby facilitating more contact with inlet air and improved efficiency of the evaporator.

COAXIAL HEAT EXCHANGER

Coaxial heat exchanger consist of spiral grooves inner tube and a outer tube. water and refrigerant in counter current flow design. Spiral grooved structure enhance the turbulence intensity, increased heat transfer coefficient.

LARGE AIR FLOW FAN

Wide fan blade, low noise, high temperature and abrasion resistant. Large air flow design, means more air into the system, accelerating the heat exchange and improve efficiency.

INTELLIGENT LCD CONTROLLER

One touch intelligent controller with Touch screen design, clear working condition displaying, and self-check function of error.

Protections

Under voltage protection Over voltage protection
Under current protection Over current protection
Phase reversal Protection
Phase imbalance Protection
Compressor high discharge Temperature protection
Compressor Overload
Anti freeze Protection
Open phase Protection
Compressor high Pressure protection
