Sizing Your Radiators
Heat Loss Calculation
Professional BTU assessment includes:
- Room dimensions (length, width, height)
- Window sizes and glazing
- Wall construction (solid/cavity)
- Insulation levels
- Desired temperature
- Cold walls (external)
Common Sizing Mistakes
- Undersizing: Room never warms properly
- Oversizing: Wasted money, slow response
- Ignoring windows: Major heat loss
- Wrong radiator type: Inefficient for space
Typical BTU Requirements
- Small bedroom (3x3m): 3,000-4,000 BTU
- Living room (4x5m): 6,000-8,000 BTU
- Kitchen (3x4m): 4,000-5,000 BTU
- Bathroom (2x2m): 2,000-3,000 BTU
Installation Process
Replacement Radiator (2-3 Hours)
1. Drain system (or isolate radiator)
2. Remove old radiator
3. Check brackets and valves
4. Hang new radiator
5. Connect pipework
6. Refill and bleed
7. Test and balance
New Radiator + Pipework (Half Day)
1. Plan pipe route
2. Run pipework from nearest circuit
3. Install brackets
4. Mount radiator
5. Connect valves
6. Pressure test
7. Commission system
Thermostatic Radiator Valves (TRVs)
What Are TRVs?
- Temperature-controlled valves
- Auto-regulate heat output
- Room-by-room control
- Energy savings 10-15%
- No wiring required
TRV Settings
- 0: Off
- 1: 5-10°C (frost protection)
- 2: 15°C (low heat)
- 3: 20°C (comfortable)
- 4: 22°C (warm)
- 5: Maximum
Smart TRVs
- Drayton Wiser: £45-£65 each
- Tado: £50-£70 each
- Honeywell Evohome: £55-£75 each
- Smartphone control
- Scheduling per room
- Energy tracking
Radiator Materials & Finishes
Steel Panel Radiators
- Most common: Affordable, efficient
- Powder coated: Durable finish
- 10-year warranty: Standard
- Available in white, anthracite
Cast Iron Radiators
- Traditional: Period properties
- Heavy: Need strong wall fixings
- Expensive: £400-£1,500 per radiator
- Beautiful: Classic aesthetic
- Slow to heat, retains warmth
Aluminium Radiators
- Lightweight: Easy installation
- Fast response: Heats quickly
- Modern: Contemporary designs
- More expensive than steel
Radiator Positioning
Best Locations
- Under windows: Counteract cold air
- On external walls: Combat heat loss
- Clear space above: 100mm minimum
- Away from furniture: Air circulation
- Accessible valves: Easy control
Avoid
- Behind sofas (blocked airflow)
- Under shelves (heat trapped)
- In alcoves (poor circulation)
- Behind curtains (wasted heat)
Energy Efficiency
Modern vs Old Radiators
New radiators:
- Better heat output
- More efficient convection
- Faster warm-up
- TRV-compatible
- Lower water content
Old radiators:
- Corroded internally
- Poor heat transfer
- Leaks developing
- Incompatible with modern boilers
Running Costs
- Well-sized system: £850-£1,600/year
- Oversized system: +20% waste
- Undersized system: Constant running
- TRVs installed: Save 10-15%
Hampstead Property Considerations
Period Properties
- Column radiators suit Victorian/Edwardian
- May need reinforced wall fixings
- Solid walls = higher heat requirement
- Conservation area: External pipes visible?
Modern Flats
- Panel radiators most suitable
- Space-saving vertical designs
- Designer options popular
- Shared walls = less heat needed
Removal & Disposal
Old Radiator Removal
- Drain radiator
- Disconnect pipework
- Remove from brackets
