Underfloor Heating, Simplified: Three Systems for Every Floor
At Theoheat, we’ve streamlined underfloor heating into three core options based on your floor build-up: Retrofit, Screed & Solid, and Joisted. No fluff—just the right system for your property and budget.
Comparison at a glance
- Retrofit: lowest height, quickest upgrade, ideal for refurb.
- Screed & Solid: highest efficiency and comfort, best with new floors/heat pumps.
- Joisted: dry install for timber floors and upper levels, lightweight and flexible.
Rule of thumb
- Tight floor height / minimal disruption? Retrofit.
- New slab or screed planned? Screed & Solid.
- Suspended timber? Joisted.
What you get with Theoheat
- Design-led: room-by-room heat loss, pipe centers, loop lengths, flow temps.
- Kit or turnkey: supply-only, commission-assist, or full install.
- Controls that work: wired or wireless zoning, app-based scheduling, heat-pump friendly.
- Guarantees: manufacturer-backed pipe warranties and documented pressure testing.

Retrofit
Screed & Solid
Screed & Solid – highest thermal mass for new builds and extensions.
Joisted
Joisted – dry, lightweight panels for timber floors and suspended joists.
FAQs
Will UFH work with my heat pump or boiler?
Yes. All three systems can be designed for low flow temperatures. Screed & Solid is the most efficient partner for heat pumps; Retrofit and Joisted also perform well with correct design.
How much floor height do I need?
Retrofit starts around 15–25 mm. Joisted depends on panel choice (from ~18 mm). Screed systems use the screed depth you’re already planning (typically 50–65 mm above pipe).
Can I use carpet?
Yes—keep the combined tog (carpet + underlay) typically ≤2.0 for good performance.
How long does installation take?
Small Retrofit rooms can be completed in 1–2 days. Joisted installs vary by access. Screed systems depend on pour schedules and drying/commissioning times.
Do I need radiators as backup?
