BTU Calculator

Radiator efficiency, is measured in British Thermal Units (BTU). The dimensions of a room are used to calculate the BTU output required to heat that room. Radiators all have a known and calculated BTU output. Using the BTU outputs in the Product Specification or description above, it is easy to calculate the size of radiator you need to help provide the total heat output necessary for your room.

How to calculate BTU requirement

The best way is to ask your plumber to perform the calculation for you. If you don't have access to a plumber, you can use the BTU Calculator below as a guide. Please note that the calculated figure relates to the combined heat output of all radiators in the room, therefore the towel rail or radiator that you purchase need not satisfy the entire BTU output if it is used to complement existing radiators.

This calculator is for guidance use only.

Average Customer Rating Milano Cayos - Luxury Anthracite Vertical Designer Radiator Sideways Panels 1780mm x 342mm has a rating of 5 stars 5 stars (2 reviews)

“Great design and practical”

Bought this radiator for my new bathroom - everyone comments on how great it looks, but it's practical too - it's so easy to clean. Nowhere for dust to accumulate - behind or between verticals.

Reviewed by TMH on 17 August 2015

“Well made, nice looking product”

The product looks good on the wall and appears made to last.
It's cast and overpainted, but does not seem to mark easily.
Fixing instructions were non-existent and the wall bolts supplied were useless for our wall. I had to purchase extra heavy duty Rawlbolts to be sure of a secure fixing, as the radiator is very heavy (as expected).
I don't need another right now, but I would buy the same again if required.
