Ian Dome Posted February 27, 2012 Share Posted February 27, 2012 Can anyone help - just had a new water mains installed due to constant leaks springing in old copper pipes. Since connecting up to the new, the flow is so much faster but the hot water isn't getting hot - it kind of gets warm, but fluctuates between cold and warm. Boiler is a Worcester Bosch.

Crosser Posted February 27, 2012 Share Posted February 27, 2012 Turn DOWN the hot water thermostat on the boiler a little. Link to comment Share on other sites More sharing options...

medusa Posted February 27, 2012 Share Posted February 27, 2012 If yours is a combi boiler then reducing the amount of water coming out of the tap should mean that the flow gets much warmer. Link to comment Share on other sites More sharing options...

medusa Posted February 27, 2012 Share Posted February 27, 2012 Yes- assuming yours is a combi boiler just turn the tap on full to get the boiler to fire and then reduce the water flow until you have the temperature of water that you want. We have just found out what was causing our dire water pressure- it was a knackered stop tap outdoors. Thankfully in checking the water pressure in the main at the boundary, which the water company do for free, they replaced the stop tap after it broke when they tried to turn it off, which means that we now have more than doubled our water flow (5 l/min to 14 l/min at the main tap in the kitchen) without paying to have the house completely replumbed as we thought we were going to have to do. The result of this was that the hot taps have gone from a scorching dribble of water to a really fast flow of tepid water, but if you turn the flow down at the tap you can actually wash your hands under the hot water without scalding them, which we've never been able to do before Link to comment Share on other sites More sharing options...

medusa Posted February 27, 2012 Share Posted February 27, 2012 The shower can pump more water, but the water consequently spends less time inside the pipes in the heat exchanger, meaning that it gets warmed up less. It's basically the same amount of warmth spread out in more water so the water is cooler. Drop the flow and hopefully you'll find a happy medium of flow and temperature. If your shower really can't warm up enough water to get the flow you want then you'll either need a new shower or a back up header tank with pre-warmed water to come through the shower- sorry.
