Im having trouble getting the heating to kick in. I have an old central heating system but with a digital clock and timer in the kitchen. When i press the boost button for water the boiler kicks in but when i do it for the heating it doesnt. Iv checked the 3-way valve upstairs and theres a lot of play in the switch when i push it one way but when i push it the other way i have to force the valve over with some pressure. Any ideas on what it could be guys x
