'Mains Pressure' Cylinder (without a discharge pipe?)

S

Struggling to get a safety discharge out of a property, are there any 'mains pressure' cylinders out there that don't require a discharge pipe? Think DPS do one but not sure

never heard of one. as with all unvented theres about three or more forms of saftey devices one important one being the blow off. but you proberbly know this with your unvented ticket if installing one.
 
In some cases you can connect a discharge pipe to an internal soil stack via a HepVo waterless trap. Probably best to check with your local Building Control whether this might be acceptable.
 
I see no circumstance where it is permissable to not have a thermal safety relief valve.

To
meet the requirements of the Regulation, installation of an unvented system
should be undertaken by a “competent installer”.
All installations of unvented hot water storage systems having a capacity of
more than 15 litres should be notified to the relevant Local Authority by
means of building notice or by the submission of full plans. It is important to
note that it is a criminal offense to install an unvented hot water storage
system without notifying the Local Authority. The installation of the unvented
cylinder and hot water system must comply with BS 6700 and the HSE
Legionella Code of Practice.

for competent installer is meant a person holding the NIC qualification for unvented hot water storage systems.

if these devices are installed with safety devices removed or omitted, they become very dangerous indeed.

dps don't appear to offer a unit without the appropiate safety features

Where did you get this nonsense from ?.
They could at least get the spelling correct if their going to use that kind of language and criminalize people for installing a hot water system.

Not nonsense, quite true. Similar to installing gas appliances without a CORGI self-certifying or a non-Corgi DIYer informing the local authority.

And following the immersion heater tragedy, discussed last week, I believe that you should also notify the local authority about the installation of vented hot water storage cylinders & complete the Benchmark certificate.

The DPS would be a vented thermal store with a mains pressure heat exchanger coil. They scale up in hradw water areas. Drivel aka Water Cisterns will be along shortly to spout of their claimed virtues at great length. He's full of carp though.
 
My understanding of the wording is ...
"It is a legal requirement that the local authority Building Control Officer be notified"

When did it change to "criminal offence" ?. I suspect it is an over zealous local authority that has added this stronger term.

obviously someones ie the author interpretaion of the term legal and the act of ilegality as being criminal, but it was a gov issue pdf :eek:
 
I sat the Bpec Unvented course a few months back an we were also told it was illegal unless competant through a governing body... Bpec for example. And Building control must be informed 30 days prior to install, again, by law!

If the UHWC is near the bathroom you can discharge through a dry trap and suitable solvent waste, but must enter suitable stack too!
 
surely if its installed by a member of a compentent persons scheme bco do not require prior notification

It's a law, Building Regs or something. The exact statute is probably listed in the unvented books 2 feet away, but I really can't be arrsed. If you break a law, the statute allows a penalty to be imposed upon you by a criminal court. You may get prosecuted and, if convicted, fined, jailed or whatever the stature allows and the court decides to be appropriate.

If you get convicted in a criminal court, you get a criminal record.

That's it.
 
Having recently discharged unventeds into soils the only manufacturer of solvent that will issue a certificate allowing 95deg water to discharge into their pipe is, Terrain. They go on to stipulate that the discharge of 95deg is for a maximum of 3 mins and then once temp drops below 87 can be used for an indefinate discharge period.
