I have moved into a new house with an old ish Worcester Greenstar boiler. This is in the loft and to control it there is a digistat box on the wall downstairs.
To start we had no hot water so I went up in the loft and have set the hot water to "on". The other choices were once twice or off. It was off.
Will this cost me loads of money to keep it on that setting? We don't have a bath so the hot water will be for washing up.
