Draining conventional system

[Andrew Robertson]

Having to clean a system prior to fitting a new heat only boiler but the customer has fitted a new floor and not left access to the pump or zone-valve.

Is there a way of draining the system without manually latching the valve open?

Could I just run the old boiler with heating on and drain it at the same time?

Cheers

It'll be possible to send an electrical signal to the zone valve causing it to open independently of the boiler. How easy it will be will depend on how the system has been wired. You'll need to provide a lot more details or consult an electrician if your knowledge of electrical work is not up to scratch.

My advice, however, is not to do anything to the system until the owner has restored access to the pump and valve. Or, at least agreed in writing that he accepts that you are likely to need to gain access and any damage to his floor will need to be made good at his expense.

Thanks for the quick reply.

That makes sense. Would be stupid not to have access for future anyway.

TBF, you sound a bit like one of the others 🙂

Why would you even contemplate fitting a boiler where you have no access to valve or pump? Commissioning will be a nightmare

That's why I was asking if there was a way of opening it. Luckily I have access to the motorised valve (only to latch it open) but I prefer to change them/the pump when installing on a system that's as old as it is.

So there is no access to two main components of the heating system.....thats nuts...tell them get a wood butcher in make an acceptabke. ...to you access hatch....give a specification ..be generous to yourself
and return when its done...they will respect your professionalism
