Lukewarm baths

[geebers]

The water in our bath doesn't get warmer than a very poor lukewarm which isn't great for bathing kids, but the sink right next to it has nice hot water. The bath has a mixer tap with one of those shower attachments coming out of it (modern-ish but Victorian looking), and when you have the hot on, just alone, it just doesn't get very hot. Can anyone advise what the matter might be? Thank you!

Probably a combi and tap fully opened on bath with large flow try closing the hot tap to reduce flow as this will allow incoming cold supply to gain more heat energy as its slower passing heat exchanger.

Thanks! I'll give it a try

No problem-let us know whether it sorts the problem or not.

Are combis really that rubbish that they can't fill a bath with a tap fully open or just some combis?

Theyre not rubbish thats just the way they are, they work like a shower the more water you put through it the cooler it is.

Watertight think of a candle wave your hand over it fast it don't hurt. Ie tap fully open.
But when you move it slow it burns. Ie tap not fully open.
Basicly if the water goes through the heat exchanger to fast it won't have time to heat it fully.
Sorry if I sound a bit patronising.

Depends on the size of the combi. A common mistake people make is getting one too small for what they want it to do.

Yes, that was the it - nice hot baths now (when the bath eventually fills up!). We've just moved and although we had a combi at our last place we didn't have the same problem. Thanks again.
