1960’s Underfloor Heating
• Mainly electric cable in thick concrete
floors
• Floor used as storage heater
• Poor controls
• Floors too hot (Uncomfortable)
• Inefficient (Generally poor insulation)
• Ineffective (Huge number of air changes)
• Ultimately unreliable (Expensive to run)

Modern Underfloor Heating
• Mainly warm water
• High tech plastic pipe in or just below floor
• Water is 45-60OC
• Forms to suit most floor constructions
• Well proven controls
• Economical to run (Especially with GSHP)
• Reliable, long lasting
• Maintenance-free

12
Underfloor Heating / GHSP Design Principles
• Ultimate performance from both systems• Perform Heat Loss Calculations• Match W/m2 from UFH with GSHP• Agree flow / return temps, depending on
floor constructions• Agree control strategy (i.e individual room
temperature control)
• Tel the customer what we can give him!!!!

Underfloor Heating / Cooling via GSHP
• Comfort cooling can be achieved by reverse cycling GSHP
• Cooling outputs of approx. 40 W/m2
• Flow / Return temperatures of 10/15°C
• Dew point control to avoid ‘Wet Floors’
• Heating / Cooling changeover controls

Five Areas of Energy Saving with UFH
•No hot air in front of glass
= Less heat loss through window
•No hot air at ceiling level
= Less heat loss through ceiling & walls
• Lower air temperature for same comfort
= Reduced number of air changes
• Uses lower water temperature
= Lower transmission losses
• Options to use Ground Source Heat Pumps
= Fuel saving economies

Advantages of UFH / GSHP
• Very comfortable– No ‘hot heads or cold feet’
– Does not promote floor draughts
– No drying of the air
– Reduced dust levels
– Beneficial to allergy sufferers, asthma etc
– Simplifies controls i.e. minimal mixing
required
• Unobtrusive– Walls left completely clear
– Floors and walls are easier to clean

• Quiet
– No creaks and groans, especially in solid floors
• Safe
– No hot surfaces - important to HSE
– No sharp edges to cause injury
– Ultimate low surface temperature radiator
– Nothing to vandalise
– In Sweden, only UFH is allowed, by law, in
children's nurseries
– Ultimate in ‘green’ energy
Other Advantages of UFH

• Complements other aspects of heating– Keeps options open for water heating
– heat pumps
• Cost effective installation– Less damage & less pilferage
– Installable in most stages of the construction
process
• Lower running costs– Low water temperature direct from GSHP
– Reduced installation problems
Other Advantages of UFH

• Improving building insulation standards leads to
reduced heating requirements
• EU regulations on energy efficiency and pollution
require low temperature emitters such as UFH
• Options are kept open for green energy sources
based on low temperatures (heat pumps)
The UK is now to rediscovering
Underfloor Heating
Why UFH / GSHP’s Relevant to You
