Central Heating Radiators

 

·       This is a consumer information video, exclusively about Central Heating Radiators.

·       It will answer the 7 questions below to fully educate both domestic end users, and tradesman. 

·       Note: We have separate videos for electric radiators… and for dual radiators (which run on both central heating and electric), so ensure you are watching the correct video.

Questions Answered in this Video (including time markers for each):

 

[01:55] 1. How do I calculate the required output? 

  • Explains how to work out the heat output requirements for your cenral heating designer radiators.
  • Discussed how to use our heat requirement calculator.
  • Also discussed how you can use your existing radiators as a guide to working out your heat output.

[03:13] 2. What’s the difference between BTUs and Watts?

  • Gives a detailed overview of the difference between BTUs and Watts as a measurement of heat output for radiators.

[04:14] 3. What does Delta mean in relation to BTUs mean?

  • Explains the difference between the different Delta outputs used in relation to heat output - Delta T50, Delta T60 and Delta T70.
  • Discusses the laboratory condition for testing heat outputs which comply with EN442 regulations.

[06:41] 4. How does the style of a radiator affect its heat output?

  • Compoares the different broad styles of radiators we offer and how the different styles directly affect the heat output.

[09:24] 5. What options do I have in positioning my radiator valves?

  • Explains the different options for locating your radiator valves on your radiator - side or underside entry.
  • Gives you the knowledge and understanding to influence the final look and enable you to discuss these with your plumber.

[10:54] 6. Whare is the best place to install my Radiator?

  • Advises the best place to physically located your radiators in your room - under a window on an external wall.

[11:25] 7. What should I know about the installation process?

  • Discusses some of the common issues customers face have after having inexprienced plumbers installing our radiataors for them.
  • Explains the process of 'balancing the system' to ensure none of the radiators are colder than the rest in the system.
  • Explains how radiator diverters (or radiator baffles) work to aid internal water flow ensuring all areas of the radiator get hot.
 

After watching this video you will know all you need to know, to make an informed decision about purchasing an designer radiators for your central heating system.

We hope you find this, as part of our series of technical videos, helpful and thank you for watching.

 

Chart for Using Your Existing Panel Radiators as a Guide to Your Required Heat Output:

When your house was built, the contractor or builder will have spent time choosing the right radiators taking into account how the house was built. We often find people seeking to replace their standard panel radiators with designer radiators, so taking the output of the existing models (if you are happy with that heat) makes perfect sense.

Measure the height and width of your existing radiator, then use the table below to find the type you have and determine its power output in BTUs. Remember if your existing radiators aren't warming your room efficiently, increase the heat output from the figures given below, for the replacement model you choose.

Converting Watts to BTUS (and vice versa)?

BTUS = Watts multiplied by 3.41,  WATTS = BTUS divided by 3.41

 

 Converting Heat Output between different Deltas?

Be mindful when comparing radiators across different suppliers to check the Delta given on the heat outputs, as this can falsify the heat outputs when comparing like for like products which have been given with different Delta heat outputs.
If it isn't specified (like it is on all of our products) you should ask the other supplier what Delta figure is used.

If you wish to convert our Delta T60 ratings, to give you a true indication as to heat output when comparing with other suppliers in different formats, use these formulas:

·         T70 = T60 multiplied by 1.33         T70 = T50 multiplied by  1.4

 ·         T50 = T60 divided by  1.264          T50 = T70 divided by  1.4

 ·         T60 = T50 multiplied by  1.264          T60 = T70 divided by  1.33
