Frequently Asked Questions
How does the 117mm depth of The Hawkhurst affect my bathroom layout planning?
The Hawkhurst features a significant depth of 117mm from the wall to the front face. This projection is deeper than many standard flat panel radiators. To avoid obstruction issues in your bathroom you must technically measure the swing radius of any nearby doors or shower screens. You should ensure there is at least 150mm of clearance space in front of the radiator to allow for safe passage and to prevent the door handle from striking the finish of the rail when fully opened.
Why is the BTU output of The Hawkhurst 1790mm model significantly higher than standard chrome rails?
The Hawkhurst 1790mm x 586mm model delivers an impressive 3163 BTUs at Delta T50. This high output is achieved because of its painted finish (White RAL 9016) and robust steel construction which has better thermal emissivity than chrome plating. If you have a large cold bathroom you should choose this model over a chrome alternative as it can technically serve as the primary heat source eliminating the need for a separate panel radiator.
What wall fixings are required to support the 32kg weight of the large Hawkhurst model?
The largest Hawkhurst rail weighs 32kg when empty and will weigh significantly more when filled with water. Installing this on a standard plasterboard wall with simple rawl plugs is structurally unsafe. To solve this problem you must anchor the brackets directly into the timber studs behind the plasterboard. If the studs do not align with the bracket positions you are required to install a timber noggin or ply reinforcement behind the wall surface to guarantee a secure load bearing installation.
Can The Hawkhurst be customized to match my specific bathroom color scheme?
Yes The Hawkhurst is available in White RAL 9016 as standard but can be ordered in S4H RAL Colours or Special Finishes. To solve design mismatch problems you can specify a custom color code to coordinate with your tiles or vanity unit. However please note that special finish orders typically have a longer lead time than the stocked white models so you must factor this into your renovation schedule to avoid delays.
What are the implications of the Delta T50 rating for use with a heat pump system?
The heat outputs listed for The Hawkhurst (e.g. 3163 BTUs) are calculated at Delta T50 which assumes a gas boiler flow temperature. If you are installing this on a low temperature heat pump system operating at Delta T30 the effective output will be approximately 50 percent lower. To solve this sizing issue you must apply a correction factor and likely select the largest 1790mm x 586mm model to ensure it generates enough radiant heat to warm the room without a secondary source.
How do I determine the correct pipe centers for The Hawkhurst before first fix plumbing?
The pipe centers for The Hawkhurst depend on the specific width of the model (286mm or 586mm) and your choice of valves. You must not assume the pipe centers are the same as the radiator width. Technically you should allow for the valve width on either side if using standard bottom connections. We strictly recommend having the physical unit and valves on site to measure the exact distance before drilling porcelain tiles to prevent costly plumbing errors.
Does The Hawkhurst require a specific type of valve for installation?
The Hawkhurst utilizes standard 1/2 inch BSP connections. If your central heating pipes emerge from the floor you will technically require Straight Valves to connect vertically into the bottom of the collector. If your pipes emerge from the wall you will require Angled or Corner Valves. Choosing Corner Valves is often the best problem solving solution for wall fed pipes as they allow the valve heads to sit neatly within the radiator profile rather than protruding into the room.
How does the number of sections affect the functionality of The Hawkhurst?
The Hawkhurst is available in 1 or 2 section configurations depending on the size. The 2 section models (like the 1790mm x 286mm) offer a unique vertical aesthetic that fits narrow wall spaces while maintaining high heat output. If you have limited horizontal wall space between a basin and a shower the narrow 2 section model solves this problem by utilizing vertical height to deliver 1662 BTUs without dominating the wall width.
What maintenance is required to uphold the 10 Year Guarantee on The Hawkhurst?
To maintain the 10 Year Guarantee you must ensure the central heating system is flushed and treated with a chemical inhibitor upon installation. This prevents internal corrosion and magnetite sludge buildup which attacks mild steel. Externally you should clean the painted surface only with a soft cloth and warm soapy water. You must avoid abrasive chemical cleaners or scouring pads as these can damage the powder coat finish and expose the steel to oxidation.
How do I bleed the air from The Hawkhurst to ensure even surface heating?
If the top of your Hawkhurst rail is cold while the bottom is hot it indicates an air lock. To fix this technical issue turn off the heating pump and locate the bleed valve at the top of the vertical collector. Use a radiator key to open the screw slightly until the hissing air stops and water flows out. Close the valve tightly and check your boiler pressure. This process removes the air pocket allowing hot water to circulate to the very top of the rail for maximum efficiency.
