Electric Boiler vs. Heat Pump Boiler: Which is the best choice?
Should You Choose a Heat Pump Boiler or an Electric Boiler?
If you are considering completely eliminating the use of gas and opting for a sustainable and modern option, it is important to find an efficient solution for heating domestic hot water. Researching the best way to heat water for your kitchen and bathroom efficiently is essential. This is where the electric boiler and the heat pump boiler come into play. In this blog, we provide more information about both products to help you make an informed decision.
Electric Boiler: Simple but Less Efficient
An electric boiler provides a straightforward way to heat tap water without gas. These boilers have a simple operation, but they are not always the most energy-efficient option. They have a Coefficient of Performance (COP) of 1, meaning each kilowatt-hour (kWh) of electricity used results in the same amount of heat output. This can lead to a significant increase in your annual electricity consumption, potentially adding over 1000 kWh per year. This raises energy costs and reduces the benefits of a gas-free home.
Heat Pump Boiler: Efficient and Eco-Friendly
For homeowners looking to go gas-free and adopt a more sustainable solution for heating tap water, a heat pump boiler is an excellent choice. These systems use heat from the surrounding air (or outdoor air) to warm water, making them far more energy-efficient than traditional electric boilers. With a COP (Coefficient of Performance) of up to 4, a heat pump boiler can generate over four times the amount of heat for every kWh of electricity it consumes. This efficiency is achieved by drawing heat from the air and transferring it to water stored in a tank. The process operates similarly to a reverse refrigerator, where a compressor and an evaporator extract heat from the air to efficiently heat your water. By choosing a heat pump boiler, you can enjoy lower energy bills and a more environmentally friendly home.
Large Capacity and Flexible Placement
Heat pump boilers often have a larger capacity than electric boilers, with common sizes of 200 liters or more. This is because they operate most efficiently at lower temperatures. They can heat water to about 70 degrees Celsius using the heat pump, with an electric element for higher temperatures, which is less efficient. The larger capacity ensures that there is enough hot water available even at relatively lower temperatures.
In terms of placement, heat pump boilers can use air from the room or outside. They can be installed in areas such as the attic, garage, or utility room. Some models connect to air ducts to draw in outdoor air, while others extract heat directly from the surrounding air. In the latter case, the space where the boiler is located may become cooler, which can be a beneficial feature during the summer.

Examples of heat pump boilers
Tosot Hombask Heat Pump Boiler
This boiler offers excellent energy efficiency with a COP of 4.0 and an A+ energy label. It uses the eco-friendly refrigerant R290 and can heat water up to 70 degrees Celsius without needing an electric element. The Tosot Hombask features multiple modes, including an automatic mode and a vacation mode, and can be controlled via the Tosot+ app.
LG WH20S F5 Heat Pump Boiler
The latest model from LG, featuring a 200-liter capacity and a COP of 3.5. Thanks to dual inverter compressor technology, the LG WH20S F5 Heat Pump Boiler boiler can heat water 20 to 30% faster than other models. The quiet unit operates at a maximum of 46 dB and can be connected to your Wi-Fi network, allowing remote control via the LG ThinQ app. The LG WH20S Heat Pump Boiler is available on our other website MaxiCool!
Choosing between an electric boiler and a heat pump boiler depends on your energy needs, budget, and preferences for environmental sustainability. While an electric boiler is simple and straightforward, a heat pump boiler offers significant advantages in terms of energy efficiency and long-term cost savings.
