EN215 is a European standard that specifies safety requirements for liquid fuel heating equipment. The standard covers various types of equipment, including cookers, boilers and water heaters used to heat buildings or water.

Thermostatic radiator valve

Angle/Straight/H thermostatic radiator valve

A device installed in a heating system to control the flow of water and distribute heat to individual rooms. Heating valves can be manually or automatically adjusted and are usually available in different types to suit different heating system configurations and heating needs.

Thermostat head

Liquid sensor thermostatic radiator valve head

This device allows the user to manually adjust the water temperature and water flow of the heater by turning a knob to control the water temperature and water flow.

Radiator valve

Automatic adjustment angle/straight radiator valve

Automatically adjusts water flow and heat according to room temperature. It uses a temperature sensing element to sense the temperature of the surrounding air and adjusts the water flow accordingly.
