Heat Pump Water Heater Manufacturers in Pune

This means one unit of electrical energy delivers 3-5 units of heat output. By comparison, a standard electric heater has a COP of 1 (100% efficiency), so HPWHs can cut energy use by 50–75%. Although the upfront cost is higher, industry studies show payback periods are often under two years for commercial installations, thanks to big energy savings. In short, HPWH specifications – heating capacity, voltage, refrigerant type, tank size, and COP – are carefully matched to the application for maximum efficiency.

ThermoChill manufactures various types of HPWHs in Pune, including integrated tank-and-pump units and split-system configurations. These heaters follow international performance and safety standards. In India, the performance of a stationary electric water heater is governed by BIS IS 2082, and safety tests must comply with IEC 60335 (adopted as IS 302-2-21 in India). Our designs incorporate stainless-steel tanks, high-grade insulation, and eco-friendly refrigerants (like R134a/R410A) to meet these regulations. The following sections will detail the main types, applications, and operating principles of heat pump water heaters.

What is a Heat Pump Water Heater?

A heat pump water heater is essentially a storage or on-demand water heater that uses an electrical heat pump (refrigeration cycle) to heat water. It typically consists of an outdoor air-source evaporator unit, a compressor, and an insulated storage tank. In operation, ambient air heats a refrigerant in the unit’s outdoor coil; the hot refrigerant is then compressed to raise its temperature further; finally it passes through a heat exchanger in the water tank to heat the water. The cycle repeats as the refrigerant returns to gas form.

By transferring ambient heat, HPWHs can achieve COPs well above 1. In practical terms, this means that for each kW of electricity consumed, the heater often delivers 3–5 kW of heat to the water, drastically cutting electricity bills. Heat pump water heaters must conform to relevant standards. In India, this includes IS 2082 (1983) for performance and IS 302.2-21 (IEC 60335) for electrical safety. Many units are also CE or UL certified for international markets. ThermoChill’s HPWH products are tested to these standards, ensuring safe, reliable operation.

Specification of the Heat Pump Water Heater

ThermoChill’s industrial heat pump water heaters come in various sizes and specifications. Below is a sample specification table summarizing key parameters for a typical model:

Each ThermoChill model can be adapted to project needs. For example, our 200 L HPWH tank uses a scroll compressor and R410A refrigerant to deliver 8 kW output with a COP of ~4 under standard conditions. Specifications vary with application – pool heaters, for instance, may prioritize continuous run capability, while residential/commercial units emphasize quiet operation and compact size.

Types of the Heat Pump Water Heater

ThermoChill produces several types of heat pump water heating systems, each tailored to different needs:

1. Air-Source Heat Pump Water Heaters – These are the most common. An outdoor unit extracts heat from air and transfers it to an indoor water tank. Suitable for buildings and factories, they can be stand-alone or integrated with an existing boiler. Compared to resistive electric heaters, these units are far more energy-efficient. (Dual-mode “hybrid” versions often include a backup electric element for very cold days.)
2. Swimming Pool Heat Pump Heaters – Specifically designed to heat pools or large spa pools. These units have large-capacity heat exchangers and robust compressors for year-round pool temperature control. They typically achieve high COP (often >4) because pool operation commonly occurs in moderate outdoor temperatures. ThermoChill’s pool heat pumps can maintain up to 35–40°C water while operating efficiently even at low ambient temperatures.
3. Spa/Jacuzzi (Hot Tub) Heat Pumps – Compact electric heat pump units that heat small to medium hot tubs and jacuzzis. They are built with corrosion-resistant components to handle spa water, and often include integrated controls for temperature and defrost cycles. Jacuzzi heaters deliver steady heat while minimizing noise, making them ideal for resorts and wellness centers.

Each type uses the same core refrigeration principle but is optimized for the heat load, ambient conditions, and duty cycle of the application. For example, swimming pool heat pumps often include all-weather defrosting to prevent ice build-up, whereas residential HPWHs may emphasize ultra-quiet fans for indoor installation.

Applications of the Heat Pump Water Heater

Heat pump water heaters have a wide range of commercial and industrial applications. Key use cases include:

• Industrial Process Heating: Factories in food & beverage, chemical, textile, and pharmaceutical industries use large volumes of hot water for cleaning, processing, or sanitizing. Industrial heat pump water heaters can supply hot water up to 90–95°C (or higher with cascade systems), cutting process energy costs. Studies show these systems can heat process water up to 200°C and often pay for themselves in under two years due to high efficiency.
• Commercial and Residential Buildings: Hotels, hospitals, apartment complexes, and office buildings require continuous hot water. HPWHs meet these loads more economically than electric resistive tanks. For example, a hotel using a ThermoChill HPWH can slash its water heating electricity by 50–60%. Domestic-scale HPWHs are also used in housing complexes, especially where gas is unavailable.
• Swimming Pools and Spas: As noted, pool and spa heating is a major application. Health clubs, hotel pools, and public aquatic centers often install heat pump pool heaters to maintain comfortable temperatures year-round while using renewable ambient heat.
• District and Community Heating: In some cases, centralized heat pump systems supply hot water to multiple buildings (like a factory campus or housing estate). Such systems can utilize ground or wastewater sources and use HPWH units as boosters.
• Food Processing & Agriculture: Dairy plants, breweries, and greenhouses use hot water or steam. Heat pumps recover waste heat or provide low-grade heat (e.g. 30–60°C) very efficiently, improving production sustainability.
• Laundry and Sanitization: Commercial laundries and hospitals with laundry services also use large heat pumps to efficiently heat wash water, meeting hygienic temperature requirements while cutting energy use.

In all these applications, the energy efficiency and ROI of HPWHs are the main draw. By significantly cutting kWh consumption, they reduce operating costs and carbon footprint. (As one analysis notes, electrified heat pumps can reduce CO₂ emissions by over 50% compared to fuel boilers)

How it Works

A heat pump water heater operates on the reverse refrigeration cycle. First, a refrigerant fluid absorbs heat from the ambient air via an outdoor evaporator coil. This low-temperature vapor is then compressed by the unit’s compressor, raising its pressure and temperature. The hot, high-pressure gas flows through a heat exchanger (condenser) in the water tank, transferring heat to the water and condensing into a liquid. The cooled liquid refrigerant then passes through an expansion valve, dropping in pressure and temperature. It returns to the evaporator to pick up more heat from the air, and the cycle repeats.

In simple terms: evaporator → compressor → condenser → expansion → back to evaporator. This continuous cycle lets the system pump heat effectively. Because the refrigerant carries latent heat, HPWHs deliver more heat per watt of electricity than a straight electric heater.

For example, if the outdoor air is at 25°C, the evaporator might raise the refrigerant to 30°C (absorbing 5°C of ambient heat), then compress it to 80°C for heating the water. Actual performance depends on temperatures; HPWHs run most efficiently when the ambient air is relatively warm, but modern designs work down to around 5°C with defrost cycles. Maintenance is straightforward: ensure the outdoor unit is clean and has airflow, and service the refrigerant system periodically. ThermoChill units include electronic controls to manage these stages, display temperatures, and automatically defrost the coils when needed.

Most models include backup heating elements or connection for an auxiliary heater. This ensures continuous hot water even in very cold weather. ThermoChill’s smart controls can alternate between heat pump mode and auxiliary mode to optimize efficiency. Safety features such as thermostats, pressure relief valves, and automatic shutoff prevent overheating or overpressure. The result is a self-contained heating system: draw heat from air, pump into water, repeat – providing hot water with up to 300% efficiency.
