Frequently Asked Questions
What technical specifications define the operating range of the Kingston thermostatic radiator valves?
The Kingston TRV range is engineered with a high sensitivity liquid sensor that operates efficiently within a standard temperature range of approximately 7 to 28 degrees Celsius. These valves are designed to handle a maximum static pressure of 10 bar and a maximum differential pressure of 1 bar. For optimal system balance and noise reduction, it is recommended to ensure the system pressure does not exceed these limits during operation.
Is the flow direction of the Kingston TRV range bidirectional or unidirectional?
The Kingston TRV range is designed as a bidirectional valve, meaning it can be installed on either the flow or return pipe of the radiator. However, for the best technical performance and to eliminate the risk of water hammer (vibrations in the pipework), it is strongly advised to identify the flow pipe and install the TRV on the inlet side where possible. If installed on the return side, the valve's internal mechanism dampens turbulence, but correct orientation is always the preferred problem solving approach.
What type of sensor is used inside the Kingston valve head for temperature regulation?
These valves utilize a precision liquid filled sensor element. Liquid sensors are generally superior to wax sensors as they react more rapidly to fluctuations in room temperature. This fast response time ensures that the radiator heats up or cools down quickly to maintain the set temperature, providing better energy efficiency and comfort control compared to slower responding wax alternatives.
How do I determine if I need Angled or Straight valves for my installation?
The choice between Angled and Straight valves depends entirely on your pipework configuration. You require Angled Valves if your central heating pipes emerge from the floor or wall and connect to the side inlet of the radiator (creating a 90 degree angle). You require Straight Valves if your pipes run along the wall or floor and connect directly into the radiator inlet in a straight line without turning. Correct selection is critical for a leak free installation without putting stress on the pipe joints.
Does the Kingston TRV range include a frost protection setting?
Yes, the Kingston TRV includes a built in frost protection setting, typically indicated by a snowflake symbol or the lowest setting on the dial. In this mode, the valve remains closed to save energy but will automatically open if the ambient temperature drops to approximately 7 degrees Celsius. This technical feature prevents the water in the radiator from freezing and expanding, which is a common cause of split pipes and water damage in unheated rooms during winter.
Can these valves be installed on any standard UK heating system pipework?
The Kingston TRV range is manufactured with standard 1/2 inch BSP (British Standard Pipe) tapered threads for the radiator tail and 15mm compression fittings for the pipework. This makes them fully compatible with the vast majority of UK central heating systems using 15mm copper or plastic piping. For installations involving microbore pipework (8mm or 10mm), specific reducers or adapters will be required to ensure a secure and watertight connection.
What maintenance is required to ensure the 10 year guarantee remains valid?
To preserve the high quality finish (such as Antique Brass or Nickel) and mechanical function, you should clean the valve bodies using only a soft, dry cloth. Do not use abrasive cleaners or harsh chemicals as they can strip the lacquer or plating. mechanically, it is recommended to rotate the valve head from minimum to maximum setting occasionally, especially during summer months when the heating is off, to prevent the internal pin and seat from seizing due to inactivity.
How does the lockshield valve function alongside the thermostatic valve?
The Kingston TRV sets are supplied with a matching lockshield valve. While the TRV controls the temperature, the lockshield is installed on the opposite side of the radiator and is used to balance the system. By adjusting the lockshield (opening it just enough to allow correct flow), you ensure that water is distributed evenly across all radiators in the house. This prevents the radiator nearest the boiler from taking all the heat and ensures distant radiators warm up effectively.
Are the finishes like Antique Copper and Nickel durable for long term use?
Yes, the finishes on the Kingston range are applied using high quality plating processes designed to withstand the thermal cycling of a heating system. The Antique Brass, Antique Copper, and Nickel finishes are treated to resist tarnishing and discolouration over time. However, careful handling during installation is crucial; installers should use a cloth inside the wrench jaws or a smooth jawed spanner to avoid scratching the surface of the nuts and valve body.
What is the delivery lead time for these specialized finishes?
Unlike standard stock items, the Kingston TRV range in specialized finishes like Antique Brass, Nickel, and Antique Copper often has a longer lead time of approximately 10 to 20 days. This is because these premium finishes are often finished to order or held in lower stock quantities. It is important to factor this timeframe into your project schedule to ensure you have all components ready before your plumber arrives for installation.
