Underfloor Heating

Underfloor heating offers one of the most efficient and comfortable ways to heat a home. With no radiators taking up wall space and heat distributed evenly across the floor, it is a popular choice for new builds, extensions, renovations, and properties looking to upgrade their heating system.

At 5 Star Heating & Renewable Energy Limited, we install and repair wet underfloor heating systems across Cornwall, bringing the same expertise and attention to detail to every project that we apply across all of our heating and renewable energy services.

What Is a Wet Underfloor Heating System?

A wet underfloor heating system — sometimes called a hydronic system — works by circulating warm water through a network of pipes laid beneath your floor. Connected to your boiler or heat pump, the system heats the floor surface from below, which in turn radiates warmth evenly throughout the room.

Because underfloor heating operates at lower flow temperatures than traditional radiators, it is particularly well suited to pairing with an air source heat pump, where efficiency is highest at lower temperatures. It can also be run from a conventional gas or oil boiler.

Underfloor Heating Installations

Whether you are building an extension, renovating a ground floor, or upgrading the heating throughout your entire home, 5 Star Heating & Renewable Energy Limited can design and install a wet underfloor heating system to suit your property and your existing heating setup.

We work on a wide range of installation types, including:

• New build properties
• Single room or whole-home installations
• Extensions and orangeries
• Renovations and refurbishments
• Installations paired with air source heat pumps
• Installations connected to existing gas or oil boiler systems

Every installation is carried out using copper pipework throughout — the same standard we apply across all our plumbing and heating work. Copper outperforms plastic in terms of longevity and water quality, and it is the material we trust in every property we work in.

Underfloor Heating Repairs

If your underfloor heating system has developed a fault — whether that's uneven heating, a zone that has stopped responding, a pressure loss, or a problem with the manifold or controls — our engineers have the experience to diagnose and resolve the issue efficiently.

Underfloor heating faults are not always straightforward to identify, and getting to the root cause quickly requires both technical knowledge and experience with a range of system types. With over 25 years in the industry, including time spent directly with British Gas and boiler manufacturer Vaillant, our team is well placed to handle complex system faults without unnecessary delays or repeat visits.

Pairing Underfloor Heating With Renewable Energy

Wet underfloor heating and air source heat pumps are a natural combination. Heat pumps work most efficiently when producing lower temperature water — exactly what underfloor heating requires — making the two technologies highly complementary.

If you are considering an air source heat pump installation alongside underfloor heating, or if you already have a heat pump and want to explore underfloor heating as part of a wider upgrade, 5 Star Heating & Renewable Energy Limited can advise on the best approach for your property.
