Wives tale water and central both on

[sawhead]

Just a query, do you have to have the hot water switched on when you have the central heating on, or is it ok just to have one or the other on?

water/central heating/both

Its all good. However, if you have a hot water cylinder and you need to have hot water for that nice relaxing bath with Mr. Matey bubble bath and scented candles then your better off turning off the central heating as this will heat up the water quicker.

Sometimes one or the other, sometimes both - just depends on the system. If radiators are warming when hot water is on then it's usually the motorised valve that has failed.

its a central heating system powered by a rayburn 20380L I presume it heats the water as well - so is it ok to have just one or the other turned on?

Yep its fine, by turning the hot water circ off basically all your doing is cutting "so to speak" a radiator out of circulation. It would be fine to run one or the other and even both.
