My CH/DHW system only has a 2 way valve to control the heating. There is no thermostat on the water cylinder or valve on the cylinder heating supply.
Is it best to add another 2 way valve to the water heating supply and a cylinder thermostat or remove the old 2 way valve and use a 3 way valve to get control over the heating and water.
Thanks in advance.
Edit - Oh and I know it's a difficult question but what's a decent price to pay to have a valve fitted?
