Underfloor Heating Installation in a New‑Build Bungalow

A self builder in Barrington, constructing a timber-framed modern three‑bedroom bungalow in required a highly efficient, low‑temperature heating system that would complement the property’s excellent insulation and meet future energy‑efficiency standards. The goal was to deliver:

• Even, comfortable heat throughout the home
• Maximum efficiency when paired with a heat pump
• A clean aesthetic with no radiators
• Long‑term reliability and low running costs

A full wet underfloor heating (UFH) system was designed and installed across the entire 120 m² floor area.

Property Profile

Feature	Details
Property type	New‑build detached bungalow
Floor area	150 m²
Construction	Timber‑frame with high‑performance insulation
Heat source	Air source heat pump (designed for 35–40°C flow)
Floor finish	Mix of LVT and engineered wood

The bungalow’s low heat‑loss design made it ideal for underfloor heating, which performs best in well‑insulated, airtight homes.

1. Wet Underfloor Heating System

• High‑quality multilayer pipework with 50‑year warranty
• Independently controlled heating zones
• Manifold with flow meters and actuators
• Smart thermostats in each room

2. Floor Build‑Up

• 100 mm PIR insulation
• UFH pipework fixed to clip‑rails
• 50–65 mm liquid screed for rapid heat transfer
• Suitable for low‑temperature heat pump operation

3. Controls & Integration

• Zoned smart thermostats for precise temperature control
• Weather‑compensated heat pump integration
• Optimised flow temperatures for maximum efficiency

Installation Process

1. Design & Heat‑Loss Calculations

A room‑by‑room heat‑loss assessment ensured correct pipe spacing and flow rates. High‑demand areas such as the open‑plan kitchen/living space were designed with 100 mm pipe spacing, while bedrooms used 150 mm spacing.

• System flushed and pressure‑tested
• Flow rates balanced
• Thermostats programmed
• Heat pump flow temperature set to 35°C for optimal efficiency

Comfort

• Even heat distribution throughout the home
• No cold spots or draughts
