Heating Options
Choose underfloor heating, radiators or a combination. A heat pump or boiler supplies the warm water.
01
Hydronic Underfloor Heating
Warm-water pipes installed within a concrete slab or screed layer. The installation method depends on the floor construction.
02
Radiators & Towel Rails
Wall-mounted radiators and heated towel rails connected to the heating circuit. Pipe access and available wall space need to be checked.
03
Hydronic Heat Pumps
Air-to-water heat pumps selected for the building's heating demand and the water temperature required by the floor heating or radiators.
Installation planning
New Builds & Renovations
| Your project | Options to explore | What to check first |
|---|---|---|
| New home with a concrete slab | In-slab hydronic underfloor heating. | Plan pipework and insulation before the concrete pour. |
| Renovation with a new screed layer | In-screed hydronic underfloor heating. | Check floor depth, finished levels, insulation and the floor finish. |
| Existing home with floors retained | Hydronic radiators, where pipe access allows. | Check pipe routes, wall space, room heating requirements and equipment location. |

Project scope
Planning Your Quote
Installation cost depends on the floor construction, areas to be heated, heat source and access for pipework. These details help define the work to be included:
- Rooms to be heated and proposed heating zones.
- Floor construction, floor finish and pipe access.
- Heat-source location and available electricity or gas supply.
- Design, equipment supply, installation and commissioning requirements.
FAQ
Common questions.
Can hydronic heating be installed in an existing home?
It depends on floor construction and pipe access. Radiators may be an option where floors are staying in place. In-screed heating needs sufficient floor depth, while in-slab heating is planned before a new concrete slab is poured.
When should I contact SmartHeat about a new build or renovation?
Contact us before floor levels, pipe routes and equipment locations are finalised. In-slab heating must be planned before the concrete pour. You can start an enquiry without completed drawings.
Should I choose a heat pump or boiler?
The choice depends on heating demand, required water temperature, electricity or gas supply and equipment space. Existing radiators or floor heating also need to be checked against the proposed heat source. Compare heat pumps and gas boilers.
Can rooms be controlled separately?
Yes, where the pipework and controls are arranged into separate zones. Thermostats and valves control the flow of heated water to each zone.
How quickly does hydronic heating warm up?
Warm-up time depends on the floor construction or radiator type and the system settings. A thick concrete slab stores heat and changes temperature slowly. Radiators and thinner floor systems may respond more quickly.
How much does hydronic heating cost to run?
Running costs depend on the building's heating demand, heat source, water temperature, heating schedule and energy prices. Any estimate should state these assumptions. See hydronic underfloor heating running-cost examples.
Which floor finishes can I use?
The floor finish must suit underfloor heating and meet the flooring manufacturer's temperature limits. Send the product details before the floor construction is finalised so they can be checked against the heating design.
