    Start with the basics. Give us the following:

    1. The precise make and model of the boiler.
    2. That red covered area - is that a hot water tank? If so:
      1. Is there a hot water thermostat rigged on its surface? Not the heating element thats in the top, but somewhere lower down, held on by a band, which measures the temperature of the tank.
    3. The thermostat for heating. What make and model is it? Take a photo with the cover off and post it here. We need to see the wiring.
    4. The pump. Would you trace the pipes. At one end it should go to a valve (usually a motorised valve). It will look either like this 3 Port Valve or like this: Two port valve.
      1. We need to know which type. If it is a three port valve, one of its pipes will head towards that hot water tank.
      2. If it is a two port valve, double check and make sure you dont have two of them.
      3. This site Central Heating Controls and Zoning - DIYWiki - see if that helps you identify the type of heating arrangement you have. Most likely it will be an S PLAN, a Y PLAN, or a C Plan. The latter two tend to be found in systems that are over 30 years old.
    5. The programmer in the house. What make and model is it?

    Come back with whatever you can gather and we'll think with you.
