What temperature should I set my boiler at to ensure optimal efficiency and comfort within my home, while considering factors such as the size of my living space, the insulation quality, and the prevailing weather conditions? Is there a universally accepted standard, or does it vary based on individual preferences and specific heating requirements? Furthermore, how do different settings impact my energy consumption and overall heating performance? Is there a balance to strike between warmth and cost-effectiveness? Moreover, could the temperature settings differ for various rooms or zones within the house? How do the needs of a bathroom contrast with those of a living room, for instance? Should I take into account the time of day or the day of the week when determining the most appropriate setting? Are there any potential consequences of setting the boiler too high or too low, such as increased wear and tear or fluctuating energy bills?
