New boiler: "Inserted necessary chemicals" - is that a Powerflush or should I worry?

Re: New boiler: "Inserted necessary chemicals" - is that a Powerflush or should I wor

1. A power flush on a 12 radiator system takes about a day, 2/3 of a day if done in conjunction with a magnetic filter. If a power flush was paid for, it should have been done.

2. Most manufacturers do not insist on a power flush. They ask for a flush in accordance with the relevant British Standard (BS7593: 1992), which can be a flush with chemicals but without the use of a separate high flow pump.

I don't think you can assume from the installer's wording that a power flush has been done. If it were me, I'd ask for confirmation, in writing, that "the system was flushed in accordance with the manufacturer's instructions and dosed with inhibitor prior to completion of the installation and commissioning". I'd also want to know what flushing chemical and which inhibitor had been used.

Thanks, ChrisX for your advice.

That is really helpful. The invoice doesn't have a GasSafe number on it, nor does it say that the installer is a Worcester engineer, so I have drafted up an email to ask him for a revised invoice with this information on it. I hope that covers everything. This is the first time I've ever had to replace a boiler in a flat - can you tell? Thank goodness for all of you guys on the forum to keep me straight. x

"Hi, X, Thanks for your invoice. Please could you possibly amend it to include the following, then resend it to me by email?

1. your Gas Safe number on it and your Worcester identifier details

2. confirm whether or not a Powerflush was done? (Sean did say when giving his original quote that he was going to do a Powerflush, so I would expect to see that listed on the invoice.)

3. A bit that details that "the system was flushed in accordance with the manufacturer's instructions and dosed with inhibitor prior to completion of the installation and commissioning".

4. Could you also detail what flushing chemical and which inhibitor were used?

Finally, please could you also confirm that you have completed a Benchmark booklet/document to prove that the Boiler was installed and commissioned correctly by a Worcester engineer/Gas Safe Engineer, and confirm where I might find this in the flat? I am going over on Friday to have a look at the boiler and my plan is to settle your invoice after I have seen the work, and pick up any relevant paperwork while I am there, so that I can bring it back with me for safe keeping.

(I hope you don't mind me asking the above. I understand that I will need all of this stuff to comply with the terms of the guarantee.)"

Hello again munchkin,

I hope that my comments have helped You to know what is required from the Boiler Installer to keep within the Terms & Conditions of the 10 Year Warranty - and of course the Yearly Servicing of the Boiler.

But please still read them carefully yourself as what I wrote was not an attempt to advise you of everything that they require.

Would You mind posting an update about the response from the Boiler Installer to your requests for the Benchmark booklet / Document - the Powerflushing details and His Gas Safe / `Worcester approved` status.

Chris

Certainly, Chris.

The booklet is beside the boiler in the flat. I'm hoping to go across on Saturday to pick that up.

He didn't do a full Powerflush - he just sent me an excerpt from the manufacturer's blurb to say that he complied with that. He did give me his Gas Safe number and I checked and he is on the register, so that's good. I forgot to ask for his 'Worcester approved' information. (I'm hoping this might be filled in on the booklet that's with the boiler.)

Here's what he replied with. I went with his quote (even though it was the same as a guy who said he was going to do a full Powerflush on the system before the addition of VAT) because I believed he was a Worcester engineer. I'm hoping that this is still the case, because he did say he was able to get me a 10 year guarantee because of this. (I can just hear other guys on the forum saying - post when you've got the booklet and don't waste our time - apologies in advance.) I just wanted to respond quickly to you.

(I'll paste it below)

Anyway, hopefully all will be OK. At least the tenant has heating and hot water, so that's the main thing, plus I'm a bit more aware than I was previously. Thanks again.

"Just to clarify with regards to the flushing of the system, a powerflush was not carried out nor was it quoted for, the flushing of the system was carried as per manufacturers instructions below and it's always included in all our boiler quotes.

BEFORE CLEANING THE SYSTEM: ▶ Ensure that the system and pipe work is in good working order. ▶ Where possible keep the existing boiler/circulating pump in place when flushing the system. FOLLOW THE GUIDANCE OF BS7593: Treatment of water in domestic hot water central heating and also the flushing guidelines below. FLUSHING THE SYSTEM ▶ Fill the system with cold water and check for leaks. ▶ Open all drain cocks and drain the system. ▶ Close drain cocks and add a suitable flushing agent compatible with aluminium at the correct strength for the system conditions in accordance with the manufacturer‘s instructions.

▶ All the following Pre-Installation sections must be read and requirements met before starting boiler or flue installations. CAUTION: ▶ ISOLATE THE MAINS SUPPLIES BEFORE STARTING ANY WORK AND OBSERVE ALL RELEVANT SAFETY PRECAUTIONS. NOTICE: ▶ Debris from the system can damage the boiler and reduce efficiency. Failure to comply with the guidelines for the use of water treatment with the appliance will invalidate the appliance guarantee. NOTICE: ARTIFICIALLY SOFTENED WATER MUST NOT BE USED TO FILL THE CENTRAL HEATING SYSTEM. PRE-INSTALLATION 6 720 815 725 (2015/05) 11 ▶ Drain and thoroughly flush the system to remove the flushing agent and debris. ▶ It may be necessary to use a power flushing machine to aid the cleansing procedure in some circumstances. ▶ Close the drain cocks and refill with fresh water and a suitable inhibitor. ▶ Vent any air from the boiler and system


Also, be assured the works has been carried to the necessary standards and the boiler does have a valid 10 year warranty.
All the necessary documents have been left on the boiler, the boiler has been registered with Worcester Bosch which I've emailed to you, the works have been notified with Gas Safe and the Buildings Control certificate will be posted to your home address, and an updated gas safety certificate will be issued via email by tomorrow the latest."
