I moved into a new build house this year and have some queries about my heating system. Basically I am trying to educate myself to make sure that I am well informed before I raise some snagging issues with the builder.
If anyone can help me agree a reasonable negotiating position I would be very grateful.
The system is a gas CH and HW system, with an Ideal ICOS HE 24 boiler. There is a white hot water cylinder in the garage and I cannot find the hot water pump. There are 2 electronic valves (2 port ones) - a silver covered Honeywell one and a white plastic covered one.
My questions are as follows:
1) The electrical wiring is terminated in a white plastic 2 gang box. It is not a proper wiring centre, and contains a jumble of wires joined with an array of terminal blocks. Is it reasonable for me to insist on a properly organised wiring box to be installed? I was going to test the thermostats etc but can't because I do not understand the array of wires.
2) When the HW programme is running (and CH is turned off), the boiler continues to run indefinately. Even when the HW temp has been reached. The boiler stays on, but the call light changes from constantly lit to flashing (and the exhaust gas level is really low). Shouldn't the boiler switch off fully?
3) The same thing happens as in (2) for the CH when the HW is off and the CH is on but has reached the CH thermostat level. Again, shouldn't the boiler turn off?
4) When the immersion heater is switched on, a hissing noise comes from the hot water tank after a while. It sounds like a pressure release. Is this OK or should there be some sort of thermostat controlling it?
5) The handover pack contained an installation checklist, with a page of tick boxes etc to be filled out when the system was installed. It was signed off at the bottom but not completed in any way. Is this dangerous? Should I insist that this is filled out and is there a legal requirement for it?
