Frequently Asked Questions

Cast Iron Radiator FAQ | Cast Iron Baths FAQ

 

Cast Iron Radiator

What is the difference between a section and a column?

A section of a radiator is the individual cast of the specific design. These casts are then joined together using steel or cast iron jointing bush to make a complete radiator to required lengths. When referring to a column we are referring to the number of vertical bars in each section.

What is a BTU and why do I need to calculate this for my room?

Btu or British Thermal Units is the heat output per hour that a radiator can produce. Using our BTU calculator you are easily able to calculate the BTU needed to make sure your rooms are comfortable and warm.

What are bush/end caps?

The bush/end caps are fitted to the end of each side of a complete radiator. They come in various sizes but the most common are 1/2” (15mm) . You will receive two caps with ½” openings to allow valves to be fitted along with one blank solid cap. One end cap with a bleeder valve is also included to allow bleeding i.e. the release of excess air.

Why do I need a bleeder valve?

Often a radiator will become warm at the bottom but remain colder at the top. This is due to air in the radiator preventing full circulation of warm water inside. You can find further information on "bleeding radiators"

What is the difference between Thermostatic valves and Manual valves?

A thermostatic radiator valve (TRV) automatically allows you to control the temperature or heat output by regulating the flow of hot water into the radiator. A TRV should not be fitted on a radiator where it is in the same room as the main  thermostat, as this can lead to inaccurate overall house temperature control. Manual valves are not sensitive to room temperature so will continue to heat a room until they are physically turned down. All manual radiator valves are bi-directional.

Are cast iron radiators heat efficient compared to normal steel radiators?

Cast iron as a material is very efficient. A radiator made of cast iron may take a bit longer to heat but once hot will retain  heat longer, even once the boiler is switched off.

What is a wall stay used for?

Wall StayA steel wall stay is used to stabilise the radiator to prevent rocking; these are essential when placing an order.

Do I need a specialised plumber to install my radiators?

All our cast iron radiators are fitted using the same techniques as modern radiators so any qualified plumber should suffice, though previous experience would be ideal.

What guarantee do I have with castrads4u cast iron radiators?

At castrads4u we offer a full 10 year manufacturing guarantee with all our radiators. Please see our Terms and Conditions for full details.

What colours can I get my cast iron radiators painted in?

If you wish a different colour than on our colour pallet we can have your radiators painted to any colour in the RAL colour Chart. Please go to www.e-paint.co.uk for the full range of colours. Farrow and Ball paint can also be used but this is more expensive. To discuss your various options regarding colour please contact us on 028 8224 5148

What if I damage the paint while manoeuvring or fitting the radiators?

Each painted cast iron radiator order will receive a small pot of touch up paint with the delivery. If more is required again please contact us.

What is the usual lead time once I confirm my order?

Once the order has been placed and paid for, delivery will take between 5-10 working days. This is due to each radiator having to be sized and tested which is a very labour intensive process. Please note that full polished radiators can take up to 15 working days.

 

Cast Iron Baths

Why choose cast iron over acrylic baths?

Saving the Earth

  • Whereas acrylic is far from being a green product, cast iron can be almost 100% recycled.
  • castrads4u strives to use mainly natural recycled and reclaimed raw material.
  • Cast iron is the best guarantee against bacteria proliferation. This is why numerous hospitals and luxury hotels refuse to use acrylic in bath equipment
  • Noise pollution becomes one of the scourges of current day life. Cast iron is simply the best material to absorb all bath and water noises.
  • In the event of fire, cast iron does not emit any gas or toxic fumes unlike acrylic.

Long-Term Investment

  • Cast iron is highly resilient. It offers best protection against scratches, etching by chemicals or detergents, cigarette burns etc. Acrylic tubs are prone to flexing while cast iron keeps it’s shape.
  • CIRBS Ltd strives to bring to? traditional and timeless designs created by master craftsmen
  • Cast iron offers top durability and strength. This longevity will ensure that even your grandchildren willenjoy it year after year.
