Extensions and New Builds
Pipework can be designed into the floor from the start, helping achieve suitable insulation, spacing and finished floor height.
Underfloor Heating Installation
Connected Gas & Heating installs wet, water-based underfloor heating across County Durham and the North East. The system connects to your boiler or wider heating setup, with Gas Safe registered engineers under number 186715 and fixed prices agreed before work begins.
- Wet underfloor heating for comfortable, even warmth
- Suitable for extensions, renovations and new builds
- Designed to work with boilers and radiator circuits
- Fixed quotation after assessing the floor and space
Even Heat Beneath the Floor
How Wet Underfloor Heating Works
Wet underfloor heating circulates warm water through pipes laid beneath the finished floor. The whole floor becomes a gentle heat source, giving more even warmth than individual radiators.
The water usually runs at a lower flow temperature than a traditional radiator circuit. A manifold distributes the water through separate pipe loops, while thermostats and controls regulate each area. The result can feel comfortable without relying on very hot surfaces or taking up wall space with radiators.
Choosing the Right Space
Where Underfloor Heating Works Best
Underfloor heating works best where the floor construction, insulation and room layout allow heat to spread efficiently. It is particularly practical when floors are already being built or replaced.
Kitchens and Bathrooms
Warm floors suit tiled spaces and free up wall space that might otherwise be needed for radiators or towel rails.
Open-Plan Rooms
Large open spaces can benefit from heat spread across the floor instead of relying on radiators positioned around the edges.
Existing Properties
Retrofitting is possible, but floor height, insulation, doors and finished surfaces must be assessed. In some rooms, upgraded radiators remain more practical.
One Connected Heating System
Underfloor Heating with Your Boiler
Wet underfloor heating can work with a suitable combi or system boiler. The design must allow the lower-temperature floor circuit to operate correctly alongside the rest of the heating system.
A manifold controls the underfloor loops, while separate thermostats can divide the property into heating zones. Existing radiators can remain upstairs or in rooms where floor heating is unsuitable.
- Boiler capacity. We check whether the existing boiler can support the additional heating demand.
- Separate controls. Underfloor heating can be controlled independently from the radiator circuit.
- Mixed systems. Floor heating downstairs and radiators upstairs can work as one planned system.
- Boiler replacement planning. We can include the floor circuit when advising on a new boiler installation.
Clear Installation Planning
What It Costs and How We Install It
The cost depends on the floor area, construction, insulation and whether the work is part of a new build, renovation or retrofit. We inspect the space and provide a fixed quotation rather than guessing from the room size alone.
We assess the heat requirement, floor build-up and existing boiler before planning the pipe loops, manifold and controls.
The floor is prepared, pipework is laid and tested, then the system is connected, balanced and commissioned before the final floor finish is completed.
Flexible payment options are available. Where underfloor heating is unsuitable, we can discuss radiator installation and upgrades instead.

Common Questions
Underfloor Heating Questions Answered
How much does underfloor heating cost?
The cost depends on the floor area, floor construction, insulation and whether the work is a new installation or retrofit. We inspect the space and provide a fixed quotation based on the actual work required.
Can I have underfloor heating with a combi boiler?
Yes, wet underfloor heating can work with a suitable combi boiler. We check the boiler capacity, controls and existing heating demand before confirming the design.
Is underfloor heating cheaper to run than radiators?
Underfloor heating can operate at lower flow temperatures than radiators, but running costs depend on insulation, controls, heat loss and how the rooms are used. Good design matters more than the heating emitter alone.
Can you retrofit underfloor heating in an existing home?
Yes, retrofit systems are possible in some existing homes. We must assess floor height, insulation, door clearances and the intended floor finish before confirming whether it is practical.
How long does installation take?
The programme depends on the floor area, preparation required and whether the work forms part of a wider renovation. We explain the installation sequence and expected timing after inspecting the space.
