Help to identify heating/boiler system

[devonshiredave]

Hi all,

I need a bit of help if any of you are feeling generous.

I need to drain my heating system to fit thermostat valves to the radiators downstairs, the problem is im not sure what sort of heating system we have so im therefore also not sure how to go about draining it depending on type.





thanks dave

It's a quite badly installed pressurised system.
You can drain it simply by attaching a hose to a low down drain-off cock. Then refill by means of the filling loop.

The installer certainly didn't cram that in did he?

..or waste any money on pipe insulation!

Cor that`s rough as rats, I hope you didn't pay him.By the way whilst you have the system drained take the opportunity to twist the pump so that the motor is horizontal,it will save the bearings wearing prematurely.

thanks,

do i need to turn off boiler etc and stop water going into it? also how do you refil with filling loop?

What makes it badly installed? sure the pipe work is messy and its crammed into a corner of our loft - but its been put there as we will be extending into part of other side of loft?

forgot to metion there is also a hot water tank, copper thing covered in foam in the airing cupboard downstairs, if that makes any difference to what type it may be?

As Dirk says, it's just rough. The pipework should be lagged even though I'm assuming that boiler has a built in Frost Stat and that pump motor needs to be flat to stop it gathering air.

Yes, you need to turn the boiler off and that silver braided pipe in the picture is the filling loop. Once you are ready open the valve and refill until that gauge shows 1 Bar cold.

Several questions

Ummm, Dave? Might be an idea to get a man in. If you don't and try this yourself, film it

I'd get the white condensate pipe lagged before the cold sets in, if that freezes up you'll have no heating at all.

Could be the least of his worry's

True, I'd be more worried about the fact that he has fitted the boiler sideways!

I'm guessing subsidence is an issue in the area as the house seems to have fallen over.
