We have a system boiler with tank (i.e. not a combi-boiler).
We were told by a plumber that it would be better to leave the boiler on constantly, rather than setting it for, say, an hour in the morning and/or evening, as it takes a lot of energy to heat the tank up from scratch. He said if you leave it on constantly it just gives the tank a wee boost of heat whenever the thermostat prompts it.
Our gas bill seems big this month (first month in this house) and I'm wondering if it's because we're doing as he suggested. Previous house had a combi-boiler, so can't make direct comparison.
