Filling loop position other than under boiler.

[cascas]

On a boiler without a integral filling loop, can the filling loop be fitted in a location other than beneath the boiler?

ie if space is tight for boxing boiler, can the loop be fitting under the kitchen sink, rather than under the boiler.

 

[SimonJohns]

Yes. Comman thing in persimmon homes

Just has to be in sight of pressure gauge

 

[desrob]

yes ...

 

[Destroyer2813]

Yes if out of sight of gauge on boiler put second gauge next to fill loop posistion

 

[warrington]

yes, why not! as long as easy access and you can see pressure gauge

 

[AWheating]

yes, if its very remote its a good idea to put a sticker on the boiler stateing the position. Could save you a call out if customer vents rads or decorates and cant find it and also helps engineers out in future.

Handy to do,when boiler is in the roof space,plus custard can keep eye on system pressure ............maybe a good place is beside toilet roll holder........so as they sit there having a boo,wondering what to do....... can top up system pressure to 1.2 :smug:

Found the blighters in loft spaces before now and possibly one solution not considered on a UK forum.
A pressure reducing valve connected to the mains supply, set at 1 bar feeding the heating circuit.
Never need to top up again until the PRV fails.
Water regs aficionados may complain but if a double nrv is fitted would there be a problem???

I've thought about doing exactly that mountainman, regards reducing valve Commercial use automatic pressurisation units that keep system pressure with fail safes that reduce the chance of an open end scenario!!

Two issues as far as I'm concerned.

1. Doesn't comply with water regs.

2. If a leak develops the constant ingress of fresh water will lead to accelerated corrosion and possible premature boiler failure. Better to sort a minor leak now than replace the boiler in a couple of years.

Issue
1, why?
2, If, what if a leak doesn't occur?

 

[Mike Jackson]

1. I've not got my guide indoors but it's something to do with it needing to be a non permanent connection.

2. If it doesn't leak it won't need topping up. If it does leak then the drop in pressure is a warning.

I've used a pressure reducing valve on a filling loop to keep a large system pressurised whilst I filled it.

 

[mountainman]

I'm just winding you up, I know the regs but I've worked in countries where no one has come to the slightest harm because a filling loop has been permanently connected via a PRV, even this overly PC and HSE obsessed one.
How long will it be before we need to provide a CRB check to get GS registered???

Had a job the other day, filling loop in attic of bungalow, access in middle of house, boiler in garage, so had to fill then run over and check, then fill, run over and check, i.e. if this was a big job, I would of got customer to keep eye on it, but what a pain.

It's got to depend on the quality of your water. If it's hard and keeps replenishing you could end up with a seriously scaled primary heat exchanger.
