hi there,
I have a 2ndhand gas boiler, and all it is doing is really HOT water or COLD water, and nothing in between.
I have adjusted the temperature guage on the front and still HOT or COLD, and the pressure is good.
When i adjust the tap area (lift and swivel), it either FIRES the boiler up at a biting point (HOT) or doesn't (COLD).
what should i do? what is wrong with the boiler? images below.
