Hi everyone, I am at my wits end and am at the point where i want to smash my boiler with a sledgehammer...
Ok I'll begin.....moved into my new house in October, the previous owner installed a new baxi ecoblue 16kw heat only boiler back in July.
Friday just gone I had 2 new rads installed as the living and dining rooms had neither (underfloor heating and a gas fire), also a new thermostat as the old one was an old Honeywell dial clicker. Rads and thermo went on fine no problems, turns out though when my installer was in the airing cupboard he found that the 3 way valve was hanging off its pipe and the previous engineer hadn't flushed out the system prior to installing new boiler....still reading? ;)
Friday evening the boiler decided to blow it's fuse, of course I am thinking wtf?! And eventually found an 3amp fuse and boiler opens up again no issues....forward to monday my engineer replaces the ball cocks in the loft as they were the outlawed ones ,replaced the 3 way and a new timer , along with adding some inhibitor as there was none in the system. He showed me the wiring in the junction box and said it looked terrible, wires all over the place so tidied them up a bit. Boiler working his job all finished, later that day the fuse blows again so I replace. ....
Fast forward to today, woke up with the heating and water nice and hot, timer set to go off at 0945...rads start cooling down at 930, and since then rads aren't warming up even though we have water, prior to all this rads would only also work with the water heated up. The thermostat is set to 23o on the wall with the little flame permanently on, the timer is showing that water and heating is on but there is no heating. Does anyone have any ideas what is going on because I want to tear out this rubbish and put a combi in its place.

Thankyou
 
Not yet, ill try again tomorrow. Looks like the immersion will be on again. With a plug in timer this time.

By plug in timer do you mean one of these:

If so make sure its ok to handle however many watts your immersion heater draws, they're a massive fire risk if you plug anything too powerful into them.
 
I was planning on something like that yes. 3120w max it says. Although no such info on the cylinder apart from redring immersion heater!

Yeh you want to read the wattage on the immersion heater itself. Assuming you've got one that's around 3kw if it was me I would not use one of those timers with it, they're notoriously shoddily made and if anything goes wrong you can be looking at a nasty fire. They do make heavy duty ones iirc that can handle higher wattages, especially higher inductive loads, I don't know enough electrixs wise to confirm if immersion heaters have high inductive loads when starting from cold light some lights do, but would not want to risk it.

E2a might not hurt to pop over to electrical forum and see what they recommend, as I say my knowledge of electrics isn't good enough to say one way or another sure but it's not something to take any chances with.

Yeah your right, I'm not going to chance it. I'll just have to wake up early to put it on for missus and boy then switch it straight off again after an hour or so.
 
Yep same as the pets falling ill at 6pm on a Friday when only the emergency clinic is open that wants £250 before they'll even speak to you and before you know it you've got a £1,500 bill that would have been <£300 during the week. Such is life sadly!
