Wet underfloor heating design and installation
Underfloor Heating Installers Across the North East
Comfortable, low-temperature heating designed around your rooms, floor construction and chosen heat source—not installed from a generic pipe-spacing rule.
Enerus designs and installs water-based underfloor heating for renovations, extensions and new-build homes across Northumberland, Newcastle, County Durham and the wider North East.
The right system for the floor
Which type of underfloor heating do you need?
The correct build-up depends on the existing structure, available floor height, heat loss, floor finish and stage of the project.
Low-profile overlay systems
Designed for projects where minimising additional floor height matters. The existing floor, thresholds, doors and final covering all need to be assessed.
- Reduced build-up options
- Useful for existing solid floors
- Quicker response than thick screed
- Requires careful heat-output checks
Screeded underfloor heating
Pipework is fixed above insulation before being incorporated into a suitable screed construction, creating even heat distribution and useful thermal mass.
- Ideal when floors are being built
- Efficient low-temperature operation
- Suitable for larger areas
- Coordinates with insulation and screed
Suspended timber-floor systems
Lightweight systems fit within or above timber structures. Joist layout, heat spreader arrangement, insulation and finished-floor resistance are important.
- For timber-floor construction
- Low structural weight options
- Responsive heating
- Detailed floor-finish assessment
Comfort with engineering behind it
Benefits of properly designed underfloor heating
The benefits depend on the building fabric, controls and hydraulic design. Good results come from matching the floor output to each room’s calculated heat loss.
Even room temperatures
Heat is distributed across a large floor area, reducing the concentrated hot and cool zones associated with undersized emitters.
Lower flow temperatures
The larger emitter surface can deliver useful heat at lower water temperatures when the system is correctly designed.
Heat pump compatibility
Low-temperature emitter design can support efficient heat-pump operation and stable comfort.
More usable wall space
Reducing or removing radiators can provide greater flexibility for furniture and interior layouts.
Individual zones
Manifold circuits and suitable controls can divide areas according to use, heat loss and required temperatures.
Quiet operation
A well-designed wet system provides heat without fans operating within each occupied room.
Multiple floor options
Systems can be designed for screed, overlay and suspended floors, subject to project-specific checks.
Clean system layout
Design drawings give installers a defined route, circuit schedule and record of where pipework is located.

How Enerus designs your system
Step 1 of 4
Understand the building and project
We review drawings or measure the property, establish floor construction, insulation, glazing, intended finishes and the proposed heating source.
Step 2 of 4
Calculate each room’s heat requirement
A room-by-room heat-loss calculation establishes the design output required. This is compared with the output available from the proposed floor construction and surface temperature limits.
- No sizing from total floor area alone
- Room-specific design conditions
- Check that the floor can meet the load
Step 3 of 4
Set pipe spacing, circuits and controls
The design defines loop routes and lengths, pipe spacing, manifold position, flow rates, zone arrangement and suitable operating temperature.
- Balanced circuit lengths
- Defined no-pipe zones and fixed furniture
- Coordination with floor finishes
Step 4 of 4
Install, pressure-test and commission
The system is installed to the agreed design, tested before covering, filled and flushed as required, balanced and commissioned with operating guidance.
- Pressure testing and installation records
- Flow-rate balancing
- Controls setup and customer handover
Boiler or heat pump
Underfloor heating is only one part of the system
The floor circuits must work with the chosen heat source, controls and other emitters. Heat pumps benefit from low design temperatures, while boiler systems still require appropriate hydraulic and temperature control.
Mixed systems—such as underfloor heating downstairs and radiators upstairs—need coordinated emitter sizing and controls. Simply adding a manifold does not guarantee correct performance.
Plan before construction starts
What affects an underfloor heating quotation?
An accurate proposal needs more than the property’s total floor area.
Heated area and room layout
Room dimensions, fixed units, stair openings, sanitaryware and other no-pipe areas influence usable emitter area and circuit layout.
Floor construction
Solid screed, low-profile overlay and suspended timber systems require different materials, labour and design considerations.
Building heat loss
Insulation, glazing, exposed surfaces and design temperatures determine how much heat each room needs.
Floor finishes
Tile, stone, engineered timber, vinyl and carpet transfer heat differently and must be included in the design assessment.
Controls and zoning
The number of manifolds, zones, thermostats and integration requirements affects equipment and commissioning.
Project readiness
Access, floor preparation, programme, other trades and whether plans are available affect the scope and delivery sequence.

Common questions
Underfloor heating FAQs
Can underfloor heating work with an air source heat pump?
Yes. Wet underfloor heating can suit heat pumps particularly well because its large emitter area can operate at lower water temperatures. The floor output must still be checked against each room’s design heat loss.
Can underfloor heating be installed in an existing house?
Often, using overlay or suspended-floor systems. Available floor height, thresholds, doors, floor condition, insulation and final coverings must be assessed before selecting a system.
How much floor height will it add?
It depends on the system. Low-profile products minimise build-up, while insulation, pipe, panels, screed or dry boards and the final floor finish all contribute. Confirm the complete build-up before ordering doors, kitchens or stairs.
Can I keep radiators upstairs?
Yes. Mixed emitter systems are common, but radiator sizing, flow temperatures, controls and the hydraulic arrangement should be designed together.
Which floor coverings are suitable?
Tile and stone transfer heat well. Many engineered timber, vinyl, laminate and carpet products can also be suitable when their temperature and thermal-resistance limits are included in the design and installation requirements.
Do I need a heat-loss calculation?
Yes, for a properly designed system. It establishes the required output in each room and allows the designer to check pipe spacing, flow temperature and whether the available heated floor area is sufficient.
When should Enerus become involved?
As early as possible—ideally before floor build-ups, insulation, screed depths, kitchen layouts and manifold positions are fixed. Early coordination normally creates more design options.
Which areas do you cover?
Enerus works across Northumberland, Newcastle, North Tyneside, Gateshead, Sunderland, County Durham, Darlington and surrounding North East areas, subject to project scope and postcode.
