heating engineer HELP PLEASE
Help please
My Mum has just rang me to see if i can help with the heating boiler
The problem is
when she switches the switch to hot water the rads come on and she can't get hot water in the taps
The boiler is a Myson Velaire oil
Will it be the timer switch box going wrong or something else ie valve not working
Thanks for any help
Jacko

is there a 3 way valve somewhere in the system? That would be my first port of call 
"That thing you're thinking - it wont be that."

Sounds like it could be a fault with the diverter valve. Doesn't have to be a combi boiler.

Mine sticks now and again, It has a lever on top, I just turn the power of and operate it manually backwards and forwards a couple of times. Seems to
do the trick

It'll be the diverter valve. They're usually built into the boiler and not as big as the one shown (which is a zone valve).
Find the diverter valve. Give it a few taps, switch the boiler on and off, if all else fails call out a plumber
99% of the time these sx will be a stuck diverter valve though..... They're a common point to fail.

Mine (before going combi) wasn't built into the boiler. Shouldn't be too expensive to replace but unless you trust the ice pack systems
will involve draining down the hot water tank & some of the radiator system.

mine did exactly the same it needed a new diverter valve cost about £45.00 and easy to fit once system had been drained down slightly
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

It may just be the motor on the actuator that needs replacing and not the whole valve......... Mines had about three new motors in the last 15 years
but still on the original valve.
