RADIATOR BASED CENTRAL HEATING SYSTEMS

Griffiths can provide the installation of radiator based central heating systems.

We purposely design and  size our radiators to maximise the efficiency of the connected boiler (increasing the condensing effect) or heat pump system (Increasing the system's C.O.P).

RADIATOR SIZING

For each room a full heat loss calculation shall be undertaken taking into account number of external walls, window area, ceiling height, type of room and occupancy.

A radiator is selected to meet the room's heat loss, factoring in the temperature of the water within the central heating system.

Radiators connected to a condensing boiler are sized to a 50-55ºC flow temperature to ensure the 'condensing effect' and maximum efficiency are achieved.

Radiators connected to heat pumps are sized (to provide sufficient output) to a 40-45ºC 'flow temperature' to maximise the systems Coefficient of Performance (C.O.P.).

Griffiths are suppliers and installers of all types of radiators, which can suited to a property's aesthetics.

In accordance with the latest addition of Part L of the building regulations, all radiators must be fitted with thermostatic valves, with each floor of a property controlled individually in a 'zone'.

POWER FLUSHING

WHAT IS POWER FLUSHING?

'Power flushing' is the process of circulating a cleaning chemical around a central heating system. Removing build ups of sludge, scale & corrosion from radiators and central heating pipe work.

WHEN TO HAVE A POWER FLUSH?

  • When a replacement boiler or heating pump is installed on a existing central heating system (To comply with Part L of the Building Regulations).
  • If radiators take a long time to heat up.
  • Your boiler is making strange 'knocking' sounds when the heating is on.
  • Your radiators only partially heat pump and have cold spots in places.
  • Your radiators require frequent 'bleeding' of air.
  • Water from the radiators comes out black when bled.

THE POWER FLUSHING PROCESS

  1. The central heating system is fully drained down.
  2. A 'Flushing rig' is connected onto the 'Flow & Return' central heating pipe work.
  3. A mix of cleaning chemicals and water is circulated (at high speed) through the central heating system.
  4. The 'Flushing rig' filters out sludge, sediment, corrosion and scale from the central heating system. 
  5. The central heating system is freshly refilled with water doused with a 'inhibitor'.

The whole process is usually completed within a day.

MAGNETIC PARTICLE FILTERS

Griffiths recommend the installation of a magnetic particle filter, which shall continuously collect fine particles of Iron Oxide that is produced over time.

It is estimated that the installation of a magnetic filter with reduce heating bills by 6%, paying for itself in less than two years!

KEY BENEFITS OF HAVING A POWER FLUSH

  • Radiators which heat pump quicker and provide greater heat output.
  • Great running efficiencies of your boiler and lower heating bills.
  • Extending the life of your boiler.
