Warm water from Cold tap?

[kevin12345]

Hi,
May sound like a silly question but I have just moved into a new house and have noticed that in the upstairs bathroom when I use the cold tap I get warm water coming out of it for about 30 seconds before it goes cold.
I never had this at my other house, is this normal, or do I have a problem somewhere?
I have a normal tank in the loft and a hot water cylinder in the airing cupboard type system.
Thanks in advance.

Not entirely unusual - a cold pipe just runs close to a hot one and the water inside gets heated up. Only way is to find the stretch of pipework involved and put insulation around the hot one.

Are you sure you have a tank in the loft and it's not a pressurised hot water cylinder?

Is it a mixer tap?
