Not very hot DHW - Any ideas?
GMM used his keyboard to write :
Standard open vented indirect tank and boiler with nothing fancy like weather
compensation etc. No recent issues. DHW timer set to run when the heating is
off.
Has the boiler flow temperature been reduced?
Check the cylinder stat temperature setting?
Check the HW time clock is on for long enough?
Check an HW tap has not been left on.
