Advice appreciated from a Boiler fitter of an 'IDEAL ICOS HE18'?

Question

I've just had boiler fitted and I'm concerned about the water temperature. I heat up water for 1 hour a day (7.30 - 8.30am) and the water is absolutely scalding. Even after having a bath and using water during the day, the water is still very hot after midnight! Surely after 16 hours and using the water during the day it would've cooled down considerably as the tank will fill up with cold every time hot is taken out? The thermostat on the tank in the airing cupboard is on 60 degrees which I was told to keep it on. Is it normal for water to remain so hot. Does it just seem odd because I can only compare it to my old boiler which wasn't as efficient, or is there something wrong with it? Any advice much appreciated

Answer 1

It does sound like an installation fault,get the installer back to rectify the fault.

Answer 2

It should never be scalding.  Lower the thermostat.  I keep  mine on pilot and it's fine, even with two showers going.

Answer 3

If you're water is scalding then the chances are the cylinder thermostat is faulty. Either that or the system hasn't been wired correctly. If the cylinder thermostat is new then the latter option is probably the best. Get an electrician to come and check the wiring. The cylinder thermostat should always be set to 60 degrees.

Answer 4

your boiler fires every time the temp drops below 60 deg. so the water will remain hot to scalding try reducing the temp.to 50 deg. it wont hurt the bioler and you might even save some money in the long run
