Dual heating system problem

mikep

Hi all

I have a heating sytem with oil burner and a boiler stove, problem is that when only oil is on some of the rads don't heat fully, when stove kicks in (independent pump operating off a thermostat) all rads heat up ok. The rad that is last in series seems worst...

I tried to balance the rads with oil only on....seemed sorted but went back to not heating properly the next day.

Any thoughts??

Thanks!

Get a heating engineer in, combining two thermal sources into one central heating system is usually to much for a joe-avarage plumber.

The heating system itself should be optimised, not only the radiators balanced. There are EN standards to follow. Get this protocoll from the heating engineer signed and dated, with all data included. This will make the job easier for next year.

Note that from 2013 ALL heating installations must be treated by this way. Better do it now avoiding the rush and prices, there is hardly any qualified staff in Ireland competent enough to do this job. Most haven't heard about it.

Thanks heinbloed

That sound serious!!

Is there anywhere I can get relevant info rearding same as our building contractor got this plumber in to do the setup and maybe they were not suitable for this....

Thanks again

The issue is not yet decided on, on how to procede. What the EU comission has in mind after years of consultations and plenty of money down the drain that each member state has to incorpota as well a controlling mechanism, not just the words but an official control if the law is adhered to.
Something like NCT for cars.
But in Ireland there won't be anything available, not now to teach and not in future to do the controls. So it would be left to the installer ( car trader) to certify the safe and efficient use of his work.

That sound serious!!

The time left to get a consumer friendly independant legislation beside the installers themself is running out, it could be only days or weeks before this EU legislation is casted.

Contact your MEP, he/she is responsible. It is getting serious.

And about the original problem: Ask for the energy demand calculated for your build. And ask the plumber to build a heating system for which he can sign the guaranteed energy usage (hopefully calculated according to the relevant EN standards).

And if any queries come up you have one to blame, the one who got the money for the job.

Hi Heinbloed

Can you povide any links to the proposal coming from the EC?

Normally all the info is freely available.

Sure:



http://www.europarl.europa.eu/sides/getDoc.do?pubRef=-//EP//TEXT+TA+P6-TA-2009-0278+0+DOC+XML+V0//EN


From 2013 all energy systems installed in buildings must have an energy rating. A rating from A-F showing the energy efficiency of the energy supply, the entire system.
Meaning the consumer can see the benefit of a particular heating system versus the costs involved.

The heating system must be designed according to EN standards to calculate it's efficiency according to EN standards.

In turn any specifier could be held responsible due to EU consumer laws if his calculations and/or specifications don't match reality (energy consumption and/or production).

I have tried to get the issue highlighted (resp. the ignorance in the trade about it ) here:

They don't understand, don't want to hear about it, the issue too complex.

Thanks for asking the right question, Mikep !

Thanks for that.....

More lovely eurospeak for me to decipher!:rolleyes:

Perhaps all the industry are assuming the whole thing will be lightly enforced, if at all...

Here news from the ST world. The report covers mainly the aspects of the ST industry, but these new regulations are about all sorts of heating/cooling devices in buildings, esp. the combination of several thermal in one distribution system :
