How old is my Grundfos pump?

Green is all a con as a kid we were heading for the next ice age, oh and they told us electric from nuclear power would be so cheap it wouldnt be worth sending a bill
and then there was the promise of more leisure time more recently renamed unemployment

Do you know that's just what all those people on the north coast of America are saying right know.

Unfortunately this is not unprecedented and has little if anything to do with climate change.

Lots of interesting reading here

We live in a modern world things change, embrace it or do you what to live life as it was 100 years ago ???

The reason they have to bring in a directive is that you lot would never move over to the new ones otherwise (How long have these pumps been out there now - 10+ years) The case for the electrical saving, let alone the heating benefits, is more than proven & just because this one action is not on its own going the save the plant what do we say Oh well wont bother with any of it. I would rather try & implement all the energy saving measures possible than have to pay my taxes to build one of them new fangled nuclear power plants, Oh shoot that my argument shot out of the water, dam.:32: rant over.

I feel like I have missed the thread about the new development in safely disposing nuclear waste. But surely fitting band A pumps will be a much worse alternative. In specific the need to read the manual. And selecting a suitable operation within all those complicated options.
Dear. What a major problem.
Instead using our knowledge to make them aware of the problems with ABVs we are like kids, "I don't like the new pumps".

One thing everyone's missing here is the cost saving to the custard. yes they cost more, our problem? no. offset onto the custard.

I really cannot see an issue here!

On the old prices it was 10-20£ before VAT. Customer will have a return of investment usually in the first heating period everything else is a bonus
And I had not one of the Alphas to change yet.

so your saying the £120 will be recouped in one heating season due to a reduction in gas and electric sorry but i find that to be an unbelievably huge saving

 

[Dotty]

You'd be talking an estimated saving of 35-40% per year.

 

[on31ll]

Have we found out the reason for wanting to know about the pump ? I have clicked on this thread about 3 times now and lost the will to live a few posts in. Am i right in assuming it works ?

 

[Dannypipe]

So between the two of you...if the customer saves 40% a year, then they would normally spend £168 a year on just powering their heating pump?

 

[dancinplumba]

when i put my heating on it uses 1.5 pence an hour in electric

 

[Dannypipe]

Think that's about £130 quid.

 

[dancinplumba]

what would i save ?

 

[Dannypipe]

£52 a year.

 

[dancinplumba]

cheers danny, not bad that, 3 yearsish and paid for itself

 

[Dannypipe]

No problem.

However this is assuming that it really can save 40%. If it really is that efficient, then they do sound good!

Grundfos quoted 39% on their Alpha range.

Weather and climate are two completely different things. Weather occurs day by day. Climate is something that can only be understood century by century.

So you would not make any connection between the ferocity or the extremes of the "Weather" & the changes in the "Climate" i.e. the warming / temperature rise ?? or would you like a lot of the rest of the world prefer to wait 100 years & then say one way or the other.

Climate is measured over decades, weather is a a day by day measurement ie cold today, warm yesterday,wet the day before. Climate= Ice age,mini ice age.

 

[nicro3]

I would love to debate weather with you mr watkins move it to the arms on another thread thanks

£52 a year.

See, if your old pump stopped working the renewal with an A pump will have played in the uprise in far less than a year. This is why I fit since years literally exclusively Alphas and Magnas. (Except in boilers with build in pumps)

Already in year one it starts paying for itself. Now there are customers that pay a lot more for electricity or have multiple pumps. The saving depends on so many factors. But none of my customers has not felt a noticable saving on his electricity bill.

Of course I do not go round and change working pumps. But where ever it needs replacement I feel the need to provide my customers with the cheaper option and that is an A pump.

Someone mentioned the energy saving bulbs not doing their job. Again there are a lot more different technologies and choosing the wrong one will provide you with the wrong result.
One prime example is a customer which had in the U/S room fitted 22 downlights with 50W and a beam angle of 25-35 degree. Room is not even 7' high. Roasting hot in summer, pretty dull at all times despite more than 1000W light fittings. These now got replaced with 1.5W warm white LED fittings with 120 degree beam angle and the room is so bright now. No thrown fuses anymore when a light fitting blows. The energy cost for using this room are now reasonable and in summer you be in it without a bucket beneath you for catching your sweat.
Before it was just putting another bulb in, now you have to consider light colour, beam angle, wattage, technology (LED,CFL,etc.). And to put cream on it the quality of those can differ so much (on different manufacturers) despite being nominal the same fitting.

 

[DirksPlumbing]

No problem.

However this is assuming that it really can save 40%. If it really is that efficient, then they do sound good!

In adaptive mode or in proportional pressure I find savings being even above that in specific if the old pump was still a 100W model and not a new 50W.
In constant pressure it will most likely be below that but usually it gets used on systems that tend to run for much longer times so the absolute saving is still high.
And even if you pick one a constant speed it will still save you even agains a 50W model.
(Read that for the 15/60, for 15/50 you can scale it down)

But in conjunction with a downsized pump and a control that allows the system to run for suitable times (Programmable Room Stat etc.) you can mostly present significant savings on both fuels.

As the Geography teacher told the class over 50 years ago:

The UK doesn't have a climate; it has weather!

 

[Dotty]

Except where I live. We have our own micro climate!
