Nu-Heat Underfloor Heating Journey | Sable Projects
From Buyer’s Guide to Warm Floors
Your Step-by-Step Journey with Sable and Nu-Heat
A clear, real-world walkthrough of what actually happens when you choose Sable as your Nu-Heat underfloor heating partner — from first questions to lifetime support.
“I just want to know what happens next”
By the time most people reach this point, they’re already interested in Nu-Heat.
They’ve seen the benefits.
They understand the comfort and efficiency.
They like the idea of warm floors and clean walls.
What they don’t want is another vague process.
“I’m interested — I just want someone to show me the steps, the decisions, and what it’s actually like from start to finish.”
That’s exactly what this blog does.
It lays out the full journey with Sable Projects and Nu-Heat, using Nu-Heat’s own three-step framework — and showing how Sable runs it in the real world.
Step 0: Get informed (without becoming an engineer)
Before anyone installs anything, most clients want to understand their options.
Nu-Heat supports this stage well with:
The Ultimate Underfloor Heating Buyer’s Guide, which explains system types, costs and running costs in plain language
The UFH Selector Tool, which helps narrow options based on project basics like new build vs renovation
Sable actively encourages clients to use these tools — not to design the system themselves, but to ask better questions.
Your job is to understand what’s possible.
Our job is to translate that into a system that will actually work in your property.
Used properly, this research phase gives clarity without overload.
Step 1: System specification with Sable
(Nu-Heat: Stage 1)
Nu-Heat’s first formal step is System Specification, supported by a personal account manager.
With Sable involved, this stage becomes practical and grounded.
It usually starts with a call or meeting where Sable reviews:
Your plans and current project stage
Your priorities: comfort, efficiency, aesthetics and budget
The type of project: new build, renovation, extension, retrofit — or a combination
Early guidance typically covers:
Warm water underfloor heating throughout vs zoned areas
LoPro® or other low-profile systems for retrofit projects
Hybrid approaches using UFH and radiators
Boiler vs heat pump — or a phased route from one to the other
At this point, Sable leans heavily on Nu-Heat’s experience as the UK’s trusted leader in residential underfloor heating, with over 80,000 installations and 34+ years of expertise, to make sure the direction is right before design work begins.
Step 2: Nu-Heat design & delivery
(With Sable coordinating)
Nu-Heat’s second stage is Design & Delivery — this is where the engineering happens.
Behind the scenes, Nu-Heat:
Carries out detailed room-by-room heat loss calculations
Designs a bespoke system: pipe layouts, manifold locations, flow temperatures, outputs and controls
Factors in floor build-ups, coverings, insulation, glazing and heat source
Engineers the system to heat the property effectively all year while running efficiently
Sable’s role at this stage is critical.
Sable:
Reviews the Nu-Heat design in the context of the wider build
Coordinates thresholds, floor heights and interior design intent
Schedules deliveries so materials arrive when the project is ready
Plans sequencing with other trades to protect the system and programme
This is where good designs become buildable designs.
Step 3: Installation & beyond
(Sable on site, Nu-Heat at your back)
Nu-Heat’s third stage is Installation & Beyond, backed by their system performance guarantee and lifetime technical support.
This breaks into two clear phases.
3a. Installation and commissioning
On site, Sable:
Installs Fastflo® tube exactly as designed, in continuous loops with no joints under the floor
Follows Nu-Heat’s drawings for pipe spacing, zoning and manifold locations
Pressure tests the system before screeds or finishes go down
Commissions controls so the system behaves as intended
This includes:
Setback-temperature strategies for screed systems
More responsive, schedule-based control for retrofit UFH, where appropriate
Every step is about protecting performance and longevity.
3b. Beyond: handover, support and optimisation
Once the system is live, Nu-Heat provides a dedicated Technical Support Team for the lifetime of the system.
Sable’s handover focuses on clarity:
How the system works day to day
How to adjust temperatures and schedules
What to expect from screed vs retrofit systems
If questions arise later:
Sable remains the on-site partner
Nu-Heat’s technical team supports deeper optimisation
There’s no hand-off and disappearance.
What the journey feels like from your side
From the client’s perspective, the benefits are simple.
Clarity instead of confusion
You always know which stage you’re in — specification, design, installation or optimisation.
Confidence instead of guesswork
Nu-Heat’s heat loss calculations and performance guarantee mean the system is engineered to work.
Support instead of abandonment
Between Sable and Nu-Heat, you’re never left with a manual and a support line that goes nowhere.
This is the essence of the partnership:
You remain the decision-maker
Sable guides the process
Nu-Heat provides the engineering depth
How to start your own Sable + Nu-Heat journey
If you’re planning a renovation or new build and want to understand how underfloor heating really fits into your project, the first step is a conversation.
👉 Book a Nu-Heat underfloor heating journey call with Sable Projects
On that call:
You share your plans, stage and goals
Sable outlines which Nu-Heat path fits best — new build, renovation, retrofit, hybrid, boiler or heat pump
You get clear next steps toward Nu-Heat’s system specification and bespoke design
