Radiator Installation Yorkshire | Professional New Radiator Fitting

Professional radiator fitting done properly:

Step 1: Heat Loss Calculation & BTU Sizing

Critical first step – ensures correct radiator size:

Our Calculation Includes:

Room Dimensions:

• Length x Width x Height (cubic meters)
• Accurate measurements essential

Insulation Assessment:

• Wall insulation type and thickness
• Loft insulation quality
• Floor insulation present
• Double or single glazing
• Door draft exclusion

External Factors:

• Number of external walls
• Window size and position
• North/south facing
• Room above/below heated
• Wind exposure

Room Usage:

• Living room (higher temperature needs)
• Bedroom (moderate requirements)
• Bathroom (high heat requirement)
• Kitchen (lower needs – appliance heat)
• Hallway (moderate needs)

BTU Formula: We use professional heat loss software that accounts for all factors, providing accurate BTU requirements.

Example Calculation:

Medium Bedroom (4m x 3.5m x 2.4m):

• Volume: 33.6 cubic meters
• External walls: 2
• Window: 1 large double-glazed
• Above: Heated room
• Below: Heated room
• Insulation: Good (cavity wall, 270mm loft)

Required BTU: 3,200-3,800 BTU

Suitable Radiator: 1200mm x 600mm Type 21 (3,500 BTU)

Why Correct Sizing Matters:

Undersized Radiator Problems:

• Room never reaches comfortable temperature
• Boiler runs constantly (inefficiency)
• Cold spots in room
• High fuel bills compensating
• Uncomfortable living space

Oversized Radiator Problems:

• Wasted money on larger radiator
• Room overheats (discomfort)
• TRV constantly closing (inefficient cycling)
• Unnecessary energy waste
• System imbalance

Our Free Sizing Service: We visit, measure, calculate, and recommend exact radiator specifications – ensuring perfect heating from day one.

Step 2: Radiator Selection & Recommendation

Choosing the right radiator:

Style Considerations:

• Traditional or contemporary home
• Existing radiator style to match
• Budget constraints
• Personal preferences
• Visible or hidden position

Technical Requirements:

• BTU output needed
• Available wall space
• Pipe connection positions
• Valve type preferences (TRV, manual)

Quality Options: We source radiators from reputable manufacturers:

• Budget Range: Compact, Kudox, Quinn
• Mid-Range: Stelrad, Myson, Barlo
• Premium: Zehnder, Vasco, Bisque

Warranty Coverage:

• Budget: 5 years typical
• Mid-range: 10 years
• Premium: 15-25 years

You can supply your own radiators or we source quality units at competitive trade prices.

Step 3: Installation Preparation

Before fitting begins:

System Drainage (If Needed):

• Drain central heating system
• Or isolate individual radiator circuit
• Minimize system downtime
• Protect flooring from water

Wall Preparation:

• Check wall strength (plasterboard may need reinforcement)
• Mark fixing positions accurately
• Drill and plug wall securely
• Ensure level mounting

Pipework Assessment:

• Check existing pipe positions
• Plan new pipework route if needed
• Decide on pipe running (surface or buried)
• Select pipe materials (copper or plastic)

Step 4: Professional Installation

Expert radiator fitting:

Mounting Radiator:

• Fix brackets to wall securely (spirit level for accuracy)
• Hang radiator on brackets
• Check radiator sits level
• Verify secure mounting (radiators are heavy when filled)

Valve Installation:

• TRV (Thermostatic Radiator Valve) on flow side
• Lockshield valve on return side
• Use quality valves (avoid cheap failures)
• PTFE tape on threads prevents leaks
• Hand-tighten connections (don’t over-tighten)

Pipework Connection:

• Connect supply pipes to valves
• Use compression or soldered joints
• Ensure watertight connections
• Support pipework properly
• Neat pipe routing

Types of Pipe Connection:

Microbore (8mm/10mm):

• Flexible plastic pipes from manifold
• Easy routing through joists
• Modern systems
• Quick installation

Standard (15mm copper):

• Traditional copper pipework
• Soldered or compression joints
• Durable, long-lasting
• Most common UK installation

Position Options:

• Bottom Center (BOC) – pipes from floor center
• Bottom Opposite Ends (BBOE) – one each end bottom
• Top Opposite Ends (TBOE) – one each end top

We match existing system configuration or optimize for efficiency.

Step 5: System Filling & Pressure Testing

Ensuring leak-free operation:

Refill System:

• Close radiator valves
• Refill heating system slowly
• Bleed air from all radiators
• Restore boiler pressure (1-1.5 bar)

Pressure Testing:

• Run heating system
• Check all connections for leaks
• Monitor for drips or seepage
• Tighten any weeping joints
• Verify radiator heats fully

Initial Heat-Up:

• Allow system to reach temperature
• Check radiator heats evenly
• Bleed any remaining air
• Verify TRV operates correctly

Step 6: System Balancing

Critical step often skipped by poor installers:

Balancing Process:

• Start with all lockshield valves fully open
• Note which radiators heat up first (nearest boiler)
• Partially close lockshields on fast-heating radiators
• Aim for 12°C temperature drop across each radiator
• Use thermometer on flow and return pipes
• Fine-tune each radiator individually
• Achieve even heating throughout home

Why Balancing Matters:

• Even heat distribution to all rooms
• No overheating near boiler, cold distant rooms
• Improved system efficiency (10-15% fuel saving)
• Extended boiler life (even load)
• Consistent comfort throughout home

Time Required: 2-4 hours for proper balancing (we don’t skip this)

Step 7: Handover & Demonstration

Completing the installation:

Demonstration:

• Show TRV operation (how to adjust temperature)
• Explain lockshield function (don’t adjust)
• Demonstrate bleeding valve use
• Provide radiator care advice

Documentation:

• Installation certificate
• Radiator warranty information
• BTU calculation record
• Lockshield settings noted (for future reference)

Cleanup:

• Remove all packaging and old radiator (if replacement)
• Clean radiator surface
• Wipe floor area
• Dispose of waste responsibly

Final Checks:

• All radiators heating properly
• No leaks anywhere
• System pressure correct
• Customer satisfied
