Frequently Asked Questions
What are the heat output specifications for the Pietra Anthracite towel rail?
The Pietra Anthracite range offers high heat output due to its powder coated finish. The compact 530mm x 530mm model delivers 992 BTUs (291 Watts), the 720mm high model produces 1364 BTUs (400 Watts), and the largest 1100mm version outputs 2281 BTUs (669 Watts) at Delta T50. You must verify these figures against your bathroom volume using a BTU calculator to ensure sufficient warmth.
Why does the Anthracite finish provide better heat output than Chrome?
Technically, the matt anthracite powder coating acts as a better radiator of heat compared to polished chrome, which can reflect heat back into the metal. This results in the Pietra Anthracite models delivering approximately 30 percent more heat output than their chrome equivalents of the same size, making them a superior technical choice for colder bathrooms.
Is the Pietra Anthracite compatible with dual fuel systems?
Yes, the Pietra Anthracite range is manufactured from mild steel, making it fully compatible with dual fuel installations. This problem solving setup requires installing a T-piece and an electric heating element, enabling you to heat the rail electrically during summer when the central heating is off. Ensure the element wattage matches the specific liquid capacity of the rail size you choose.
What is the wall projection depth for installation planning?
The Pietra Anthracite has a rail depth of 115mm. When planning your installation, you must account for the wall bracket clearance, which typically results in a total projection of 108mm to 122mm from the wall. This technical detail is crucial for ensuring the rail does not obstruct shower doors or walkways in compact spaces.
Do I need special valves for the Anthracite finish?
The Pietra Anthracite is sold as the radiator unit only, so valves are not included. While standard chrome valves work, for a cohesive designer look, we recommend pairing it with matching Anthracite or Matt Black valves. You will need angled valves if pipes come from the wall or straight valves if pipes come from the floor to ensure a neat connection.
How durable is the matt anthracite finish in a bathroom environment?
The Pietra features a high quality powder coated finish that is specifically engineered to resist corrosion and wear in humid bathroom conditions. To maintain this finish and prevent technical issues like surface degradation, clean only with a soft damp cloth. You must avoid abrasive cleaners or scouring pads that could scratch the matt surface.
Can the Pietra Anthracite be installed with the bars facing either direction?
Yes, the Pietra features a reversible design, which is a key problem solving feature for difficult layouts. You can install the radiator so the open ended horizontal bars face either left or right. This flexibility allows you to position the open side for the easiest towel access depending on where your vanity or shower is located.
What is the warranty period for this designer radiator?
The Pietra Anthracite is backed by a comprehensive 10 Year Guarantee. This warranty covers technical manufacturing defects such as leaks, weld failures, or finish issues. This long coverage period reflects the robust mild steel construction and ensures the product will withstand the rigors of daily use in a wet environment for a decade or more.
How do I bleed the air from the Pietra Anthracite if it has cold spots?
If the top of the rail is cold while the bottom is hot, trapped air is restricting circulation. To solve this, locate the bleed valve (air vent) at the top of the vertical collector. With the heating system turned off and cool, use a radiator key to slightly open the valve until air hisses out and water begins to trickle, then close it tightly to restore full efficiency.
What are the pipe centers for the Pietra Anthracite installation?
The Pietra has adjustable wall brackets that allow for pipe centers of 73mm to 87mm from the wall. However, the width between the pipe inlets depends on the vertical collector spacing. We strongly recommend receiving the product and measuring the exact centers with your chosen valves attached before laying any underfloor pipework to ensure a precise technical fit.
