Your combi boiler's ideal temperature for central heating
At ProTech Boilers, we recommend setting your room thermostat at between 18 and 21 degrees Centigrade to optimise your boiler's performance. Studies have found that this is the most comfortable interior temperature range for the majority of people surveyed. For older or less mobile people, between 22 and 23 degrees is a better temperature.

A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa). High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction techniques become necessary, but some had boilers that operated at over 1,500 psi (10.34 MPa).
