700 x 600 Radiator FAQs
Are Coloured Radiators Better Than White?
We’re not here to say some radiators are better than others as each type of radiator we offer here at Stelrad are great options. Of course, the type of specs and colour you choose depends on your needs and preferences. However, research shows that darker colours such as black (RAL 9005 colour) radiators emit more heat due to their colour. You can use our heat loss calculator to find out which radiator is the best option for your home.
What is the Difference Between K1, K2, & K3 700 x 600 Radiators?
As mentioned previously, there are many codes for the radiators featured on our website. These describe the heating technology within each. The following is a breakdown of specifications:
- a radiator with 1 panel and 1 row of convector fins is a K1 or Type 11 radiator
- a radiator with 2 panels and 1 row of convector fins is a P+ or Type 21 radiator
- a radiator with 2 panels and 2 rows of convector fins is a K2 or Type 22 radiator
- a radiator with 3 panels and 3 rows of convector fins is a K3 or Type 23 radiator
You will find a “Type” dropdown menu on each product page. Here it will show you whether the radiator is available as a K1, P+, K2, or K3 radiator.
