Installation Requirement for Radiator
Choosing a radiator with the correct output
It is important to note that the radiator outputs listed in the manufacturers brochures are derived from tested outputs obtained under specific test Conditions. Therefore outputs may vary depending on the installation and heating design requirements of the room.
Calculations to accurately size a radiator to provide enough heat output to satisfy your individual comfort conditions, is dealt with in the heating system design section.
Sitting radiators
Whilst the location of radiators under window is recommended to reduce cold down drafts, the length of curtains, which could adversely affect the distribution of heat when closed, should be considered. The location of radiators at the entrances to a property is particularly important to offset the ingress of cold air into the building. The reduced accessibility and the safety of the occupants, especially the young and infirm, due to radiator sitting should also be taken into consideration.
You should also not that a double radiator has less heat output than two single units though the overall size may be the same. In other words, two single radiators are more efficient than one double.
One good thing about modern designs is that you have much more flexibility in locating your radiators. For example, if the existing position of furniture is limiting your options, you can choose a tall, narrow unit that takes up minimal floor space.
Clearances
When sitting radiators it is important to remember to leave adequate clearance for heat circulation and valve installation. The recommended height from the floor to the base of the radiator is 150mm.
Connections-tapping
Top Bottom Same End (TBSE) or Top Bottom Opposite End(TBOE) connections are often used in commercial and elderly applications where top valve mounting is advantageous. A further advantage is that the radiator can be mounted either way up.3/4〞x 1/2〞BSP adapters which allow 3/4〞valves to be fitted direct to the radiator; ideal for commercial applications.
It should be noted however that in all pressed steel radiators, restrictive washers are welded as an integral part of the radiator, this is to provide strength for the tapping connections. As a result some system(one pipe) will require swept bends or diverter valves to ensure to an adequate flow rate.
Flushing corrosion
Will take place to a greater or lesser extent in all domestic central heating systems. Just how severe it is will depend on many factors including the types of metal in the system; they degree to which air can be drawn into the system; the nature of the supply water. Even the quality of the installaion work can have an effect. On completion of the installation the system should be proberly flushed and filed in accordance with the British Standard Code of Practice for the Treatment of Water in Domestic Hot Water Central Heating Systems BS 7593. This will remove flux residues and installation debris, which might promote corrosion and damage within the system. If it is decided to apply a corrosion inhibitor to maximize the working life of the system, it should be applied in accordance with the manufacturers instructions and should be suitable for the particular metals within the system.
Additional specification pointers and installation tips
Extension tubes Nickel plated brass rediator extension tubs are available from Stelrad in 20mm, 30mm and 40mm sizes. These enable the engineer to replace imperial sized radiators to a metric size without draining down the system. Variable radiator extention tails also available from most plumbing merchant stokists.
Brackets
Deep hanging slots and equidistant lug positions ensure greater stability. Plastic inserts designed to seat the radiator precisely, are essential to minimise expansion and contraction noises.
Plug and vents
These are the Achilles heal of any radiator. Sacrificial nickel plated plugs and vents enable replacement, as a component part of the radiator, unlike roll top radiators which have the vent welded into the radiatoras an integral part.
Top grills & panels
Where top grills are specified ensure that they have no joins or seams along the top upper surface, thus ensuring a safe top/upper surface which will not catch dusters or cut small hands.
Pressure testing
Radiators should be high pressure tested to 152.3PSI (10.5 bar) to perform at a maximum working pressure of 116 PSI (8 bar) at a maximum temperature of 95℃. This enalbes that whatever the heating application from conventional pressurised domestic to high rise installations or commercial projects the radiator can be specified with confidence.
Warranty
A manufacturers warranty of at least 5 years should be obtained, however, check that radiator is date stamped to provide clear date evidence. Some manufacturers rely on paper inserts which need to be retained by the installer.
BS.EN 442
Radiator sold in the EU have to conform and have outputs verified to BSEN442 the European standard for radiators. All radiators literature needs to display BSEN442 compliance, this enables specifiers to show compliance with the European construction products directive.
Aesthetics
New 33.5mm presses give a higher definition and more accurate dimensions. The pitch of each complete waterway should have connector fins welded onto the waterways. This ensures maximum efficiency, lower running costs (due to low water content) and fast heat up time.
Paint
Two coating, power paint finish is more scratch resistant than traditional paint or resin finishes. Electrophonetic base coat with power coat finish, gives a better, more even coverage in a better, more even coverage in a warmer white RAL 9010. No further painting is required and the finish remains white and does not discolour.
