Radiator installation – sizing compatibility and piping
Before you install a new radiator, prior planning and thought should be given to choosing the right size radiator that can produce enough heat to maintain an adequate temperature in the room. Radiator installation and repair comes as second nature to a seasoned plumber, the usual per installation checks includes radiator sizing, location, piping. Compatibility also plays a crucial part meaning can the existing boiler cope with an additional radiator being installed to your central heating system.
A Mears calculator can be used to work out the heat requirements for a room. It uses a mathematics formula correlated from; the measurements of the room, i.e., weight, length, width and also the flooring and window type. The calculus can also easily be acquired online by searching for radiator online sizing; this will give you a rough guide of what size radiator will be required. However, the best way to get an accurate calculation is to enlist the services of a plumber.
Radiator installation – after removal for a renovation
A problem often encountered by plumbers when carrying out radiator installation is a reversal to of the typical installation procedure. Radiators can often be removed for renovation; the supporting brackets are removed and either covered by wallpaper or even worse covered by plaster.
The standard sequence for a radiator installation is to firstly, erect the brackets then place the radiator on the wall followed by the piping. Without the brackets fitted or clearly marked out for installation, a plumber will be encounter difficulties.
To avoid a problem like this, before removing radiator brackets always make a note of the positioning. This can easily be done by replacing fixing screws into the holes. Ideally, the disconnection and reinstallation should be carried out by the same person who is familiar with the layout before and after the refurb as been completed. This simple process will eliminate the need to reconstruct pipework to suit the new positioning of the radiator.
The curved or angled radiators can often be found in old Edwardian buildings, this was the fashion of the day, when central heating was in its infancy. The flowing contour of a cast iron radiator beneath a bay window would create an elegant classic look. To overcome the curvature in some instances, a bay window may have three radiators strategically placed at angles covering the area beneath the window.
A curved radiator is not a product that can be easily purchased like the standard type found at your local plumber’s merchants. Curved radiators are unique in their design, they are a bespoke product tailored to suit varying specifications of the wall where it is to be mounted. These types of radiators are notoriously difficult to be replaced after a refurb that can often charge the curvature of the wall. A job like this will require two people to gently coax the radiator into its supporting brackets.
What to do about a leaking radiator
Leaks commonly associated with a radiator are found in four places, A the bleed nut , B the radiator valve, C connecting pipe, D the radiator. Central heating repairs often require the heating system to be drained down, this is the starting point before any repairs can be carried out. Damage pipework or weaken joints can easily be repaired, However leaks to the radiator will require a placement. The high system pressure and temperatures that exceed 50 degrees C will not be contained within a corroded radiator, a temporary fix is not recommended.
One of the difficulties that is commonly faced when carrying out a radiator repair is leaking, attention to detail is paramount if pipework is incorrectly fitted it will result in leaks. Thus the repair will take twice as long due to having to drain the heating system in order to make further adjustments.
