It's a set containing one Thermostatic Radiator Valve (TRV) to control radiator heat output based on room temperature, and one Lockshield valve to balance the heating system's water flow. This provides a complete solution for one radiator.
Yes, for optimal control and system balance, both the inlet (TRV) and outlet (Lockshield) valves on a radiator should be functional. This twin pack provides both necessary valves.
The LavaTherm twin pack is designed for standard 15 mm UK central heating pipework, which is the most common size. It is compatible with most radiators and boilers.
The TRV head typically has a dial with numbers (e.g., 1 to 5). Lower numbers correspond to lower temperatures, and higher numbers to higher temperatures. A setting of '3' is often a good starting point for average room temperatures (around 20°C).
Balancing involves adjusting the Lockshield valve to ensure all radiators heat up evenly. This typically requires the heating to be on and involves gradually opening or closing the Lockshield valve while monitoring radiator temperatures.
Basic plumbing knowledge is required. If you are not experienced with central heating systems, it is highly recommended to have a qualified professional install the valves to ensure proper function and prevent leaks.
A manual valve requires you to turn it up or down by hand. A TRV is automatic; it senses the room temperature and adjusts the water flow to maintain your set temperature, saving energy and improving comfort.
Ensure the TRV head is not set to 0 or the frost protection setting. Check that the heating system is on and the boiler is firing. Verify the Lockshield valve is open.
Check that the TRV head is correctly attached and properly set to a lower temperature. If the problem persists, the TRV may be faulty and require replacement.
This usually indicates a system balancing issue. Adjust the Lockshield valve to allow more return flow. Consult system balancing guides for detailed instructions. Air in the radiator can also cause this; try bleeding the radiator.
Check that all fittings are secure. If leaking from the valve body or gland, the valve may need tightening or replacement. If leaking from the pipe connections, the compression fittings may need adjustment.
The TRV head may have come loose from the valve body. Ensure it is securely attached according to the manufacturer's instructions. If damaged, the head may need replacement.
Compatibility:
This twin pack is specifically designed for standard 15 mm UK central heating pipework. It is compatible with most domestic radiators and boilers. Ensure your existing radiator has 15 mm pipe connections for proper fitment.
Installation:
*Note: If you are not comfortable with plumbing, it is recommended to hire a qualified professional for installation.*
Care:
To maintain performance, periodically check for leaks. Clean the valves with a soft, damp cloth. Avoid using abrasive cleaning agents that could damage the finish. The TRV head can usually be removed for dusting or cleaning around the valve body.
