Heat Pumps Explained and Why They Matter to Wardtec

Heat pumps have become a hot topic lately, but what exactly are they? Why are they gaining traction, and why is this important for Wardtec?

While there are many detailed articles available on heat pumps, let’s start with a simple explanation of what a heat pump is and how it works. In essence, a heat pump is a device that transfers thermal energy using the refrigeration cycle, which operates through mechanical compression. A key feature of heat pumps is their ability to reverse the process, allowing them to either heat or cool a space. In fact, most homes already have a heat pump in their refrigerators, which work to cool a space. A heat pump that operates in reverse can warm a space, making it an efficient option for home heating.

How Heat Pumps Work
For home heating functions by absorbing naturally occurring heat from the environment; this can be from the air, ground, or water. This heat is transferred to a fluid, which is then compressed, raising its temperature. The heated fluid can then be used in a heat exchanger to warm water and provide central heating.

The majority of domestic heat pumps fall into two categories:

1. Ground Source Heat Pumps

2. Air Source Heat Pumps

Why Heat Pumps Matter
For the UK to achieve its ‘Net Zero’ target by 2050, it is estimated that over half of all homes will need to adopt heat pump central heating, up from the current 1%. With over 80% of UK homes still relying on gas boilers, the heating industry is facing significant changes, particularly the phasing out of gas boilers, especially in new constructions.

Key Considerations
Heat pumps are extremely efficient and environmentally friendly compared to traditional gas or oil boilers. Although they require electricity to operate, this can be sourced from renewable energy, such as wind or solar power. While they are more expensive to install than gas boilers, they are much more cost-effective in the long run, offering a good return on investment. However, they may not be suitable for every property type, especially high-rise apartments or homes with limited outdoor space. They are also more complex to install, particularly in retrofitting projects. But they are ideal for new builds, where all factors can be considered from the outset. Though already popular in Europe, the UK is increasingly embracing heat pump technology, and proper understanding and setup are crucial to maximizing their efficiency.

Why Heat Pumps Matter to Wardtec
Wardtec is a leading producer and supplier of components for the hot water cylinder industry. Both air and ground source heat pumps require a hot water cylinder to facilitate heat transfer for central heating and hot water supply. Currently, a significant portion of the UK market relies on combi boilers, which do not require hot water cylinders. However, as combi boilers are phased out, more homes will need hot water cylinders to work with heat pumps.

This anticipated increase in demand for hot water cylinders has prompted Wardtec to expand its capacity and expertise, ensuring we remain a trusted and reliable supply partner to manufacturers of hot water cylinders and related heat pump components. As hot water cylinders become more complex, Wardtec is committed to meeting these evolving market requirements by continuously developing our manufacturing processes and supply systems to ensure long-term reliability and quality.
