What to consider before you Buy Heat Pump?

Buying a Heat Pump isn’t very easy. You will have to make sure that you take the right decision to meet your hot water needs. Before buying a heat pump, you need to look at certain aspects to achieve maximum efficiency.

A heat pump is a huge investment because of its high upfront cost. It is the cheaper alternative in the long run, only if you choose the right one. There is a checklist that you need to consider before you buy a heat pump.

In this blog, we will see what that checklist is. Let’s get started with some fundamentals.

What is a heat pump?

A heat pump water heater is a water heating system that absorbs surrounding heat to heat the water. It consumes less energy than a traditional geyser. So, it reduces greenhouse gas emissions, resulting in a lower carbon footprint.

Also, a heat pump system can last up to 15 years if maintenance is done properly. Imagine you don’t need to change your appliance for so many years. It reduces wastage as well.

How does it work?

The heat pump system works on the principle of transferring heat from one place to another. The exhaust fan absorbs heat from the surrounding air. The heat is then transferred to the compressor, where the temperature is increased. Then this heat is transferred to the storage tank where water is stored.

This process continues. Normally water is heated at a temperature of 55°C. But you may change the temperature manually as per your requirement. If you set the temperature above 55°C, it will use the backup coil to heat the water as per the desired temperature set by you.

Before you buy heat pump hot water system, you should consider the following:

1. Capacity

When considering the purchase of a heat pump water heater, it’s crucial to assess your household’s hot water demand. The capacity of the water heater should be sufficient to meet your daily hot water requirements, considering the number of people in your household, their bathing habits, and any other hot water needs. Choosing a water heater with inadequate capacity can lead to frequent shortages of hot water, while an oversized unit may result in unnecessary energy consumption and higher upfront costs.

2. Coefficient Of Performance

The COP is a measure of a heat pump water heater’s energy efficiency. It represents the ratio of heat output to the electrical energy input. A higher COP value indicates greater efficiency and lower operating costs. In India, where electricity rates are relatively high, it’s essential to choose a heat pump water heater with a high COP to maximize energy savings and minimize the impact on your electricity bills.

3. Space

Heat pump water heaters are typically larger in size compared to traditional water heaters, as they require additional space for the heat pump components and air circulation. Before making a purchase, ensure that you have sufficient space available in your home to accommodate the water heater’s dimensions. If enough space is not available at your home, you may purchase a single unit heat pump, instead of a split one.

4. Weather Conditions

Heat pump water heaters are designed to operate efficiently within specific temperature ranges. In India, where temperatures can vary significantly across regions, it’s essential to consider the local climate conditions. Some heat pump water heaters may struggle to perform optimally in extreme heat or cold, requiring supplemental heating or cooling mechanisms, which can increase energy consumption and costs. So, you need to buy a heat pump that will suit the weather conditions of your location.

5. Brand

When it comes to heat pump water heaters, the brand you choose can have a significant impact on the product’s quality, reliability, and after-sales support. Research reputable brands with a proven track record in the Indian market, and consider factors such as warranty coverage, customer service, and availability of spare parts. Investing in a quality product from a reliable brand can save you money in the long run by reducing the risk of frequent repairs or premature replacement.


Before buy a heat pump water heater, consult professionals, who can guide you in the right direction. Purchasing a heat pump will take you one step towards sustainability. But it is only efficient if you know which is the best heat pump to buy. By evaluating the capacity, COP, space requirements, weather conditions, and brand reputation, you can make an informed decision that will provide you with reliable hot water while keeping energy costs in check.
