Q1: Are you a manufacturer or trading company?
A:We are professional OEM/ODM thermostat manufacturer since 2003 with 7000sqm factory.
Q2: How does a boiler thermostat work?
1) To supply hot water to home radiators stalled at each room
2) To supply hot water for home showers and taps
Q3: What’s the best temperature for a boiler thermostat?
It’s recommended that you set your radiators to 75°C (no higher than 80°C) and your hot water to 60°C (no higher than 65°C).
If you set your hot water to anything below 60°C, you risk contracting Legionnaires’ disease. If the water in your cylinder isn’t hot enough, bacteria can grow and put your health at risk. 60°C is too toasty for bad bacteria, and not too scalding for you.
As you’ve probably observed, your tap/shower water should always be a lower temperature than your radiators.
Meanwhile, we recommend that you set the temperature of your room thermostat to around 19-20°C, and your thermostatic radiator valves to number 3.
