A mate has heating problems. He had a powerflush 2 years ago which didn't
fix it. He had a contract with Scottish Power and all they can do is offer
to fit a new pump despite his pump being onto 2 years old. The say he needs
a powerflush - surely not!

The problem is - how can he find someone to diagnose and fix the problem.
It is not a traditional plumbers (pipe strangler) job. It is not a boiler
problem. It could be balancing or control.

Who has the diagnosis skill and commitment to find and fix the problem
without just replacing things and doing money making jobs?

Maybe tell us what the problem is?

So what are the problems ... not all rads getting hot, or overall not
providing enough heat? Something else?

If he turns all but one rad off, one at a time, are they each capable of
getting hot individually?

I have not been to see it for myself. It seems that some downtairs
radiators do not heat up. I have talked him through balancing and checking
his TRVs are not stuck.
He claims his DHW gets really hot - I have suggested he sets the cylinder
stat to a lower setting - he tries to control things with his timer. I even
wonder if there is a wiring issue. Some parts are not very accessible and I
don't want to go round as I might attract a ping-****it.
It just seems that many plumbers are really pipe fitters or new part
fitters and don't spend time understanding a system and doing a proper
diagnosis.

Heating engineer vs plumber?

If you said what town it is, someone here might know a heating
engineer in the area capable of diagnosing a system fault.

Air lock in pipes feeding radiators? Turn off all radiators except one
that's not getting hot and perhaps turn the pump to the highest speed
for a short period.

The bathroom radiator in the cottage we rented a couple of weeks ago was
cold despite the pipes to and from being hot. I luckily the bleed screw
was slotted so I didn't need a key to bleed it. Once bled of more air
than I ever bled from one rad in the past it worked perfectly.

I told the owner what I had done when they called in later in the week.
The response "Bled ??? sorry I don't know what that is" !!!

I thought we all carried radiator keys on our keyrings! Perhaps it is only
for when we have daughters in rented university accomodation!

OK. This sounds very familiar.

There is a 3 way valve that has got stuck so that the hot water tank is
always being heated and one of the house zones is never heated.

wonder if there is a wiring issue. Some parts are not very accessible and I
don't want to go round as I might attract a ping-****it.

I'd trace back the hot water coil feed and find the offending valve.

It may just have seized up completely or the motor burnt out - my
parent's has stalagmites underneath it! It could be that the control
signals are not reaching it but mechanical failure is more likely.

The superheated hot water is a bit of a give away.

Is there also an immersion heater that may have been left on?



A recent observation with my own heating system where a tank of water
can be heated by both the boiler and a immersion heater. Water heated by
the immersion heater is too hot [1] even through the immersion
thermostat is set to 60C. 2 digital thermometers with wired sensors
were placed with one sensor at the top of the tank and the other half
way down. Both in contact with the copper tank and both under the fairly
thick insulating jacket.

When heating the water by the boiler
top of tank = 59C, mid tank = 58C

When heating the tank by immersion heater
top of tank = 74C, mid tank = 57C


I assume from this that the temperature sensor for the immersion heater
is actually in the end of the long probe that fits into the immersion
fitting and monitoring the temperature mid tank.

[1] The immersion gets switched on about once every 3 months to give a
quick boost to the heating of the water so its not too much of a problem.
