Boiler in integral garage:
* Boiler discharges at low level in the garage
The pressure relief valve will only discharge, in a fault condition, it must do so where it is visible, and in a safe position so the occupier does something about it.
A garage floor meets all the regs, although most would prefer it outside.
* No frost thermostat installed
Some if not most new boilers include frost protection.
* Pipework not insulated
All at risk pipework should be lagged, a simple job to rectify.
* Boiler incorrectly wired.
Need more information on what is incorrect, and whether the boiler, heating etc worked.
* Benchmark book not filled in, a requirement for registering with Corgi.
A requirement,and the only thing GSR may be interested in as far as the boiler is concerned.
* No system by-pass and no room thermostat to comply with the manufacturers instructions and building regs.
Not all systems require a by-pass, and some boilers have them built in, a room stat or control is required in the main living space.
* Heating motorized valve locked in open position
The MV is manually opened to fill the system, as soon as power is applied it should release itself.
* Incorrect wiring to programmer.
In what way.
* Wiring center cover left off, exposing live terminals.
screw it back on, see note at the bottom.
* Hot water thermostat on Ariston pressurized hot water cylinder missing
they are bult in, has it been removed or just not wired up.
* Electric immersion (13 amp) wired into wiring center (3 amp). Intended to operate as a thermostat? Does not work
unacceptable see note at bottom.
* No balancing valve on cylinder
explain, the cylinder should have a pressure reducing valve on the mains cold feeding the cylinder, having a balanced cold is not a requirement.
* No automatic air vent
Where and does it need one.
* No pipe insulation
a Building requirement.
* No extra support on roof joists
More information how it's installed and what size joist are used etc.
* Discharge valve from pressure reducing valve disconnected from tundish, terminates in a bucket.
unacceptable.
* Discharge pipe from cylinder terminates at high level under gutter.
Completely unacceptable, and must be to low level in a safe and visible position.
My conclusion is that the problem is 90% electrical, and may have been done by a non-qualified or illegal worker, and out of the heating engineers/plumbers hands.
Unvented cylinders are dangerous if not 100% by the book, and you need a person holding a G3 unvented ticket, but that falls down if the electrician is a chancer, if in this case it was notified through Corgi the they will check it out, otherwise it comes under the building inspector.[/i]
