Frequently Asked Questions
Does the 454 BTU per section output of the Neo Georgian 6-Column 660mm radiator make it suitable for low-temperature heat pump systems?
Yes, it is technically one of the best radiators for heat pumps. The 6-column design at 660mm height provides a massive surface area (approx. 0.35m
The radiator is 221mm deep; exactly where should my pipe centers be roughed in from the finished wall?
The pipe connections are centered in the section width. For a 221mm deep radiator, the center is 110.5mm from the back face. You must add a minimum air gap of 30mm (ideally 40mm for a 6-column unit to aid convection). Therefore, your pipe centers should exit the floor at 140mm - 150mm from the finished wall/skirting. Standard 70mm pipe centers will be completely unusable for this model.
Why is spray painting recommended over brush painting for the Neo Georgian 6-Column 660mm radiator?
While the surface is smooth, the 6-column depth (221mm) creates very deep, narrow gaps between the columns. It is physically impossible to reach the inner surfaces of columns 3 and 4 with a standard paintbrush without bridging the paint or leaving bare patches. Bare cast iron will rust. Spray painting (using an angled nozzle) is the only technical way to ensure the protective coating reaches the core of the radiator to prevent corrosion.
Does the 660mm height allow this radiator to be installed under a standard dado rail?
A standard Victorian dado rail is typically fixed at 900mm - 1000mm from the floor. The 660mm Neo Georgian leaves a clearance of 240mm+ below the rail. This is technically excellent for convection, as the powerful updraft from the 6 columns can dissipate freely without trapping heat against the moulding, preventing woodwork warping or plaster cracking.
What cleaning tools are required to maintain the thermal efficiency of a 6-column deep radiator?
Dust accumulation in the center of a 6-column radiator creates an insulating blanket that significantly reduces convective output. Because the gaps are deep (221mm front-to-back) and narrow, a standard duster won't work. You technically require a 700mm+ long, tapered radiator brush (goat hair or microfiber) that can pass all the way through the sections to dislodge dust from the central columns annually.
Can I assemble a 20-section Neo Georgian 6-Column radiator on my own?
Absolutely not. A 20-section assembly weighs 192kg dry. It is awkward and top-heavy due to the 660mm height. Attempting to lift or move this manually risks severe injury or dropping the unit, which will crack the brittle cast iron. You need a team of at least 3-4 people or mechanical lifting aids (like a piano trolley) to move it into position safely before connecting the valves.
How does the water volume of the Neo Georgian 6-Column 660mm affect system warm-up times?
This radiator acts as a "heat battery." With ~2.5L of water and 9.6kg of iron per section, it has huge thermal inertia. It will take 45-60 minutes to reach full temperature from cold. You must program your boiler to fire up 1 hour before you need the room to be warm. Conversely, it will continue to heat the room for over an hour after the boiler turns off, so you should set the heating to stop early to save energy.
What size Joining Key is required for the Neo Georgian 6-Column 660mm radiator?
Because the radiator is 660mm high and 6 columns deep, the joining nipples are under significant tension to hold the heavy faces parallel. You generally need a Heavy Duty 3/4" or 1" Joining Key (check specific nipple size, usually 1" for massive units) with a long tommy bar (600mm+) to generate enough torque (approx 80-90Nm) to compress the gaskets sufficiently without leaking.
Are standard wall stays sufficient for the 221mm depth of this model?
No. Standard wall stays are typically 160mm long. The rear column of the Neo Georgian 6-column sits approx 140mm from the wall (including air gap). A standard stay would be extended to its absolute limit, which is unsafe for a 300kg radiator. You must specify Extra-Long Luxury Wall Stays (250mm+) that can be cut to length, ensuring a substantial portion of the rod remains anchored in the wall plug for maximum pull-out resistance.
