Pipe and frost stat, do I still need them?

[timtheenchanter]

My CH system is 3 years old, when installed it was installed in an unheated outhouse, hence (presumably) the pipe and frost stat in there with it.

I have now remodeled the kitchen, removing the partition wall between the outhouse and kitchen to give a bigger kitchen.

now that the boiler is inside, does it need the frost or pipe stat? the pipes that it is attached to will be inside a stud wall.

Personally, I can't see the need for them now its in the heated house, but im not a CH engineer.

Forgot to ask the engineer when he serviced it, did check about flue distances from the window though (its fine)

You dont say what your boiler model is(some have built in frost protection)
If the boiler and pipework is now in a heated area, then frost protection is not required, although leaving it in position will do no harm.
It will provide protection if the house is left unheated for extended periods.

Its a Baxi Duo-Tec 24HE.

There may/may not be room for the pipestat in the wall in its present position, might be able to move things around, ill have a look.

The CH programmer does have a frost stat built into it (wireless remote one) so there is some protection (if you trust wireless)

If its a duotec combi 24 HE then it has built in frost protection which operates when system water reaches 5*C.

cheers, have just discovered that the pipe and frost stats were wired in series , is that normal? seems daft to me, as both the pipe and frost would have to kick in for the boiler to operate.

The frost stat turns the system on, the pipe stat turns it off. Simples.
