Hi there, bit of a hot water issue (or more lack of it) ever since I installed a new bathroom a few months ago. When the hot water tap is fully open the boiler heats the water as normal but intermittently the gas cuts out for 10-15 secs until the water cools back to 60 degs and then fires up again. If I crank the tap back this doesn't happen but takes an eternity to run the bath. Is this normal for a high flow rate or is there possibly something with the boiler? No fault LED's or anything like that. To be fair the boiler is over 12 years old with heavy use and the only thing I've had to replace is the diverter diaphragm.
Thanks in advance for any assistance.
