10. Hot Flow


Hot Flow | Jordan Traditional Thermostatic Radiator Valve Angled TRV Satin Brushed Nickel Angled TRV

Hot Flow #ad - We recommend all trvs are installed on the flow rather than the return pipework of a radiator. The jordan thermostatic radiator valve is a traditional radiator valve. Decorator's caps are used to fully isolate TRV valves whilst a radiator is removed for decorating. The handle of this valve is a matt black composite material; durable and attractive.

This allows the valve to open if the temperature falls below 6°C, protecting your system and home from flooding in the event of freezing conditions while you are away from your home. This valve set comprises a high-quality TRV and a matching lockshield for balancing your central heating system. Satin nickel angled thermostatic Radiator Valve Pair - The Satin Nickel may not match all Satin Nickel on the market. System automatic bypass valves are a specific building regulation requirement for all new installations and boiler upgrades.

When used in conjunction with a system automatic bypass valve this thermostatic valve can be installed on either the flow or return in any orientation. The trv and lockshield are cast from brass and finished in your desired colour, making it perfect for traditional Victorian home installations. All trvs from any manufacturer require the bypass valve to function correctly and thus avoid radiator hammer. This trv features discreet temperature indicators on its neck – from 6°c to 30°c - as well as frost protection when the control head is turned fully clockwise.
