Wet Underfloor Heating is the most cost-effective and comfortable way of heating your home. An UFH system consists of the pipework, manifold, fixing materials, insulation and the controls. Pipes laid beneath the flooring (as the name suggests) are used to heat the room. The manifold regulates the flow of the system and most systems are pressurised, usually to 1 bar.

Over the years, Underfloor Heating has become an integral part of any new-build property. For the progression of renewables, this is fantastic to see, as both Ground and Air Source Heat Pumps accompany the technology perfectly. However, regardless of what heating source you are using, underfloor is always the best option in new-build projects, as a lower flow temperature is required to heat your home when compared to radiators therefore lowering your running costs.

Despite being a more common acquisition with new/self-builders, Underfloor Heating can still be retrofitted into existing properties. Whether it is an 1980’s Victorian property or a two-up, two-down townhouse, wherever our heat pumps go, Underfloor Heating usually follows.

Why Choose Underfloor Heating?

Radiant Heat

There are lots of advantages to UFH, when compared to traditional radiators. Firstly, a radiator will heat up its immediate surroundings and said heat is subsequently dispersed to cooler areas such as leaky windows, and therefore lost, this process is known as convection. However, underfloor heating transfers heat over a much larger surface area, therefore heating objects and people directly.

Reclaimed Space

Aside from the more technical benefits, there are many aesthetic appeals to underfloor too. Conventional radiators can often disrupt the decorating process of wall spaces in any property. On the other hand, with underfloor heating, you are able to claim that space back and enjoy every inch of the space room’s space. Whilst radiators used to be considered an ugly necessity, the option for a more aesthetically-pleasing way of heating your home is now readily available.


Generally, comfort is high on the agenda of anyone that is looking to implement a new heating system; new-build or retrofit. Also, in spaces such as kitchens or bathrooms, which are commonly tiled, you won’t be greeted with the sharp, cold feeling on your feet. Furthermore, the stuffiness that traditional radiators can create in your rooms is a thing of the past with underfloor. Convection relies on the movement of air, resulting in the circulation of dust and mites. With UFH, the objects/surfaces are heated, rather than the air around them.


Another advantage, which is perhaps considered less by consumers, is the increased safety of Underfloor Heating. Younger or even elderly members of your household could potentially be greeted with hard, metal edges should they be on the wrong end of a trip or fall – which is completely negated with an underfloor system.

Underfloor Heating and Heat Pumps

Underfloor Heating and Air/Ground Source Heat Pumps go hand in hand to form an incredibly efficient way of heating any property. Heat pumps work better when they are required to produce lower flow temperatures. As the UFH pipework covers a much larger surface area than traditional radiators, the water flowing through it does not have to be as hot; only 35-40℃ is required compared to the 50-55℃ that is required with radiators. As a result, the running costs for your heat pump will be significantly reduced. This is outlined in the table below.

Our System

Installing Underfloor Heating is more often than not a simple process. As previously mentioned, the kit consists of 5 parts. The three most significant parts, are the manifold, the pipe and the controls.

Hero underfloor manifolds are manufactured from European produced steel hollow sections with a unique, 3mm thick composite. This is where the pressure is held and maintained, to ensure that the circulation is as efficient as possible. The pump housing is wall-mounted stress-free, so no irritating pump noises will occur.

Hero’s highly flexible and easy-to-process pipe, consists of a base pipe and an outer layer of oxygen-impermeable PE-RT. The oxygen-impermeable jacket is resistant to damage during installation. It is essential to ensure that a full room-by-room survey is carried out so that the pipe spacing is correct.

The Hero Room Control system or RCE, consists of a room thermostat and receiving unit, which can be connected wireless or hard-wired. The system has several intelligent functions, like an adaptive/self-learning weekly programme, a holiday function, the possibility to connect external sensors, external temperature control via GSM-switch (optional) and more. Room Controls allow you to split your Underfloor Heating system into multiple zones. Instead of a single zone valve, a wiring centre is installed with actuators, which will provide independent control for each of your underfloor heating zones. Systems can be split across as little as two rooms, to entire floor spaces (e.g. basement, ground and first floor).

How Do I Get Started?

As with all aspects of any new-build or retrofit project, it is important to form a positive working relationship with your Underfloor Heating installer. More importantly, is ensuring you choose the right installer. Hero Renewables are heavily regulated by several governing bodies, to ensure that all of our systems do exactly what they are supposed to. When installing Underfloor Heating with a Heat Pump, it is essential that the necessary calculations are made, such as a room-by-room heat loss, to ensure your system provides for the demand required.

Hero Renewables offer everything from the design and supply, to the installation and support of UFH, so no matter what stage your project is at, we’re here to help.

We can work and collaborate with everyone involved in your project. Whether it’s building contractors or architects, getting us involved in your project as early as possible will allow us to be there every step of the way and ensure everything runs smoothly for you.
