Keswick 600 x 785mm Cast Iron Style Traditional 3 Column Regal Blue Radiator

Traditional style radiator

1st October 2026

Excellent traditional-style radiator. The Regal Blue colour is beautiful and gives the radiator a really distinctive, high-quality appearance. It feels very substantial and looks like a traditional cast-iron radiator, while actually being made from steel. It gives out plenty of heat and makes a real feature of the room rather than just being functional. Very pleased with both the quality and the overall look.

FAQ's

What are the benefits of a 3 column radiator?

  • Higher heat output: Three columns provide more surface area for heat distribution than a 2 column radiator of comparable size.
  • Good balance of size and performance: They provide additional heat without the greater depth of a 4 column radiator design.
  • Versatile option: Suitable for a variety of rooms and heating requirements.
  • Traditional style: Their classic column design works well in both period-inspired and more modern interiors.
  • Range of sizes: Choose from different dimensions and heat outputs to suit your room.

 

Are 3 column radiators suitable for larger rooms?

3 column radiators can be suitable for medium to larger rooms, depending on the radiator's size and BTU output. For rooms with higher heat requirements, choosing a larger 3 column radiator can provide the heat needed, while still giving you the traditional column radiator style.

 

Are 3 column radiators efficient?

3 column radiators can provide effective heating when correctly sized for the room. Having more columns can increase the radiator's surface area and heat output, but it doesn't automatically make the radiator cheaper to run. 

Choose a model with the appropriate BTU output for your room for effective heating. Our BTU guide can help you calculate this.

 

What size 3 column radiator do I need?

Start by calculating the BTU output your room requires, taking into account factors such as room size, insulation and windows. Then choose a 3 column radiator with sufficient heat output, being sure to check its height, width and depth against your room measurements to make sure it’ll fit in your available space.
