Frequently Asked Questions
The Neo Georgian 4-Column 660mm radiator has an output of 317 BTUs per section; how does this compare to the lower 505mm model for sizing a room?
The 660mm model provides approximately 43% more heat per section than the 505mm version (317 BTU vs 222 BTU). This means to heat a room requiring 5000 BTUs, you would need roughly 16 sections of the 660mm model (approx 1m wide) compared to 23 sections of the 505mm model (approx 1.4m wide). The 660mm height is technically more space-efficient for wall width.
Does the 660mm height fit under a standard dado rail without disrupting convection?
Yes. A standard dado rail is usually fixed at 900mm-1000mm. The 660mm radiator leaves over 200mm of clearance. This is technically ideal for convection, as the 4 columns generate a strong updraft that can dissipate freely without being trapped by the moulding, preventing heat buildup and woodwork damage.
Is the Neo Georgian 4-Column 660mm radiator safe to install on a first-floor suspended timber floor without reinforcement?
A 20-section radiator weighs 111kg dry and holds ~30kg of water, totaling ~140kg. While this is heavy, it is often within the static load limit of sound Victorian timber joists if positioned perpendicular to them (spanning 3-4 joists). However, you must check the floor condition. If the floorboards are thin or the joists are widely spaced, we recommend using a spreader plate or positioning the feet directly over the joists to prevent long-term deflection.
Can I paint the Neo Georgian 4-Column 660mm radiator myself if I buy the
Yes, but it requires technique. The 660mm height and 4-column depth mean there are deep internal surfaces. Using a brush is difficult and often leads to drips running down the tall columns. The technical recommendation is to use a spray gun or aerosol metal paint to coat the inner columns evenly. If you must brush, use a long-handled "radiator brush" to reach the center first before finishing the outer faces.
What size wall stay is required for the 144mm depth of this model?
The rear face of the radiator sits approx 30mm from the wall. The clamping point (between the rear columns) is roughly 70mm from the wall. A standard 160mm wall stay is usually sufficient, but you may need to cut the threaded rod down. The stay should be clamped near the top (approx 550mm high) to prevent the tall, narrow unit from tipping.
Is the Neo Georgian 4-Column 660mm radiator compatible with
Technically yes, but not recommended for long banks. The internal water volume is moderate (~1.5L per section). For radiators up to 10 sections (~4500 BTU), 10mm pipework can work if the pump pressure is good. However, for banks of 15+ sections, 10mm pipes will restrict flow, causing the radiator to heat up unevenly. We strongly advise upgrading to 15mm copper tails for consistent performance.
How do I clean the internal columns of the 660mm high radiator?
The 144mm depth allows easier access than the 6-column models, but the 660mm height makes it hard to reach the bottom from the top. You should use a long, tapered radiator brush (70cm+) that can pass all the way through the 4 columns from top to bottom. Regular cleaning prevents dust from acting as an insulator on the internal surfaces.
Does the water content of the 660mm model require an external expansion vessel?
A 20-section model holds roughly 30 Litres of water. If you are adding 3 or 4 of these to a system, you are adding 100L+ of volume. This will likely exceed the capacity of a standard combi boiler's internal expansion vessel (usually sized for ~80-100L total system). You will technically need to install an additional external expansion vessel to prevent system pressure from spiking when the heating is on.
