Frequently Asked Questions
Q.
Is the Reina Slimline Horizontal compatible with a heat pump?
A. Reina publish a Delta T30 output for every Slimline Horizontal size, so it can be used on a heat pump system - use the Delta T30 column in our heat output table for accurate figures. Size the radiator against that column rather than the gas boiler figures.
Q.
Can I use this radiator with an electric or dual fuel system?
A. No - Reina list the Slimline Horizontal for central heating only, so it is not available as an electric or dual fuel version.
Q.
What valves do I need for the Slimline Horizontal?
A. Valves are not supplied with the radiator. Pipe centres match the radiator width (400 to 1400mm), with 30 to 55mm from the wall to the pipe centres - add 90mm to the pipe centre measurement if you are including the valves, and check these figures before ordering.
Q.
What are the pipe centres and wall distances on the Slimline Horizontal?
A. Pipe centres equal the radiator width, so a 600 x 800mm radiator has 800mm pipe centres. Wall to pipe centres is 30 to 55mm, and the radiator projects 62 to 87mm from the wall for all six widths.
Q.
Can I use the Slimline Horizontal as a towel rail?
A. No - the Slimline Horizontal is a flat panel radiator with no rails or bars, so it will not hold towels. If you want a towel warmer in this range, see the separate Reina Slimline Towel Bar.
Q.
Which size Slimline Horizontal do I need?
A. Use the room fit calculator on this page. Enter your room dimensions and heating system type and it shows which width meets your heat loss. All six widths share the same 600mm height.
Q.
What finishes is the Slimline Horizontal available in?
A. White and Anthracite, across all six widths. Both finishes have the same construction and heat output.
Q.
What is the Slimline Horizontal guarantee and maximum operating temperature?
A. Reina back the Slimline Horizontal with a 5-year guarantee. The standard maximum water temperature for this type of steel radiator is 95 degrees C.
