When upgrading to an energy-efficient heat pump, many homeowners in the UK often ask: “What type of radiator is best for a heat pump?” At Prisma Boiler Grants, we have helped numerous households make the switch to greener energy. Choosing the right radiator is essential, not just for comfort but for energy savings and maximizing system efficiency in 2025.
In this guide, we will walk you through the most suitable radiators for heat pump systems and how selecting the right one can lead to significant savings on your heating bills.
Why Radiators Matter for Heat Pumps?
Heat pumps work differently from traditional gas or oil boilers. They deliver lower flow temperatures (typically 35°C to 55°C), which is much lower than the 70°C to 80°C temperatures typical of a gas boiler. Because of this, standard radiators may not be sufficient to effectively heat your home.
By choosing the right radiator, you can ensure that your heat pump operates efficiently, providing consistent warmth while keeping your energy bills low.
Best Radiators for Heat Pumps in 2025
Here are the types of radiators that work best with heat pumps:
1. Oversized Radiators
Oversized radiators have a larger surface area, which makes them highly effective for low-temperature heating systems like heat pumps. They are designed to emit more heat even at lower water temperatures, ensuring a comfortable indoor temperature.
2. Aluminium Radiators
Aluminium radiators are known for being lightweight and responsive. These radiators heat up quickly and retain heat for longer periods, making them an excellent choice for heat pump systems. They are also available in a range of modern designs that can fit any home décor.
3. Low-Temperature Radiators (LTRs)
Low-temperature radiators are specifically designed to work with heat pumps. These radiators have a larger internal water volume and are designed to operate effectively at lower temperatures, ensuring your system remains efficient and your home stays warm.
Can I Keep My Existing Radiators?
It is possible to keep your existing radiators, but it is not usually the most effective option. Many older radiators are designed for higher temperatures, which can result in inefficiency when paired with a heat pump. Using existing radiators may cause your heat pump to work harder than it needs to, leading to higher energy bills and decreased efficiency.
At Prisma Boiler Grants, we offer free home surveys to assess your current radiators and determine whether an upgrade is necessary.
Radiators vs Underfloor Heating: Which Is Better with a Heat Pump?
While underfloor heating is an efficient solution, installing it in existing homes can be costly and disruptive. Radiators are a more practical and cost-effective solution for most UK homeowners making the switch to heat pumps.
