Designing UFH for premium new builds.
How we coordinate underfloor heating, hot water and controls on £1m+ residential schemes.
Underfloor heating has become the default choice for premium new builds across the South East. When designed and installed correctly, it delivers even, efficient warmth with none of the visual intrusion of radiators — exactly what architects and homeowners want in high-end properties.
As an official NU Heat partner, we design UFH systems that are calculated specifically for each property. This isn't a one-size-fits-all approach. Every room gets its own heat loss calculation, pipe spacing, and flow rate — ensuring consistent temperatures throughout the house.
The coordination challenge on a new build is significant. UFH pipes need to be laid after the slab or screed substrate is ready but before the final screed pour. That means we're working in close coordination with the groundworks team, the screed contractor, and the flooring installer. Timing is everything.
We always recommend wet UFH systems over electric. Wet systems are more efficient to run, integrate seamlessly with both boilers and heat pumps, and deliver a more natural warmth. The initial installation cost is higher, but the long-term running cost savings make it worthwhile on any property where the budget allows.
Manifold placement is another critical decision. We position manifolds centrally to minimise pipe run lengths and ensure even flow distribution. On larger properties, multiple manifolds may be needed — each serving a zone of the house with independent temperature control.
Controls have advanced significantly in recent years. We typically specify smart thermostats with individual room control, allowing homeowners to set different temperatures in different zones at different times of day. When integrated with a heat pump, the system can modulate output to match demand — saving energy without sacrificing comfort.
One common mistake we see on projects where UFH has been poorly designed is cold spots near external walls. This happens when pipe spacing isn't tightened in high heat loss areas. Our designs account for this with closer pipe centres around perimeters and under large glazed areas.
The result, when done properly, is invisible heating that just works. No radiators cluttering walls, no cold spots, no complicated controls. Just consistent warmth throughout a beautifully finished home.
