Gas Boiler Water Temperature Setting

If you can raise the temperature manually do not set it any higher than 210 f which is often the limit and try to remain down at 190 f if you need the extra heat.

Gas boiler water temperature setting.

Typical operating temperatures on a hydronic boiler call for a high temperature boiler cuts off of 180 200 f. The boiler is maintained at a different scale the 180 to 140 range because you have to. On the other hand the epa suggests turning the thermostat down to 120 to reduce power consumption and a booster heater to reach sanitizing temperatures at select outlets. Unlike lowering the temperature in a combi boiler cylinders will take time to cool down if they are at maximum temperature already.

How to set the temperature on a viessmann boiler. For gas boilers the dew point is around 55 c. Water heaters are factory set at osha recommended levels around 140 degrees. It can also provide a boost in cold weather if your hot water is not quite hot enough.

This means that the water needs to be 55 c or lower for your boiler to maintain its efficiency. Set your boiler temperature to 65 c in summer between medium and low and adjust down if your water feels too hot. In other words the water in the return pipe needs to be 55c or lower or your boiler will not operate at maximum efficiency and potentially. Over 30 psi boiler pressure will cause the pressure relief valve to open.

The average setting for a gas powered hot water boiler is 180 f. The dew point temperature is a measurement that determines the humidity of air and is the temperature at which water droplets form in the heat exchanger. Typical operating temperature settings on a boiler call for a low temperature boiler cut in between 120 and 160 f. For natural gas boilers the dew point is around 55c.

It can vary from 70 degrees room temperature up to 180f if you need it.
