central heating pump replacement

[TBServices]

So what did he say ?

I seem to remember the same sort of conversations taking place over old style (non condensing) gas & oil boilers & who is still installs them.
How about TRV's the list goes on, always ends up the same in the end the industry takes it onboard eventually there just has to be the bitching first, even when with a little investigation it is quite clear it is the right thing to do.
I suppose it is part of human nature that some just don't like change of any sort.

For good reason Chris. Early condensing boilers - rubbish, trvs - rubbish, and even if you get non rubbish ones, the customers don't know how to use them, modulating pumps are just another hunk of rubbish forced upon us by people who have no experience of their workings.

80 year old Agnes with 30 year old radiators and a ideal Mexico, doesn't want a a HE pump, and she won't benefit from it.

Oh great, working on that principle then I am sitting around my open log fire, in my great hall (did allow myself the luxury or a roof over my head) covered in soot cos em new fangled chimneys don't work anyway & I know of at least two that fell down after being built !!!!!

I'm guessing you'll still be able to get the old style pumps for combis though? I can't imagine the new energy efficient ones will fit in to most combis!

I'm not against the new pumps and have fitted them but common sense has to be used. When the old heads are phased out you can guarantee the majority won't be set right anyway. It is bad enough now when most out there can't read a pump graph and bung everything on speed 3 (usually causing system problems) just to be sure it works. You will probably find most Alphas will be set to CP2 just to be sure it works

You would fit one of the new UPS2 pumps. Same sized pump head with a lower wattage.

Btw i was out and swapped a pump head this morning. Bog std 15/50 replacement.

In the real world Mrs Noheat wants it fixed.
She rings you for a price. You say sure a new A rated pump that will save you 20p a week on your leccie, supplied and fitted for £200
She rings the next guy who says no probs i'll fit you a pump (any pump, myson, screwfix shyte) for £150.
She takes the £150 offer and he got the job and made about £50 more than you would have at your £200 asking price. Her heating is working and she couldn't care less about 20p a week and if it breaks down again 2 years later such is life.
That is the reality i'm afraid, no matter what some bureaucrat says must be done to save the planet if indeed it really needs saving.
Devils advocate :smile:

So offer your customer 3 options:

A rated expensive branded pump @ £high price
A rated less expensive unbranded pump @ £mid price
Non A rated cheap pump @ £budget price

I bet most of them take the middle option.

We find that all the time - if we offer 2 products which do much the same job, the cheapest one sells most.

If we offer 3 products that do the same job, the middle-priced one will out-sell the other 2 put together.

You will probably find most Alphas will be set to CP2 just to be sure it works

To cast that in numbers:
System x conventional pump 4.5kW/day
Alpha 2L CP2 1.5kW/day
Alpha 2L III 3kW/day

VPs can not get used in the system as causing lock out by overheating since the ABV does not open (fixed setting).

Now do the maths with your 20p/week.

Grundos Selectric 15-50 number 2 setting 70 W I'm with tamz on this one

Alpha 2L III 3kW/day

Now do the maths with your 20p/week.

There must be a lot of hours in your day :wink:
A 15/50 draws between 40 and 90 watts /hr depending on how it is set. Speed 1 running 10 hrs a day 400w or speed 3, 900w. electric @15p/kwh is 6p/day(10hrs) on speed 1 or 13.5p on speed 3.

An Alpha draws between 5 and 30 odd watts depending on how it is set or is working so say on average for easy counting it is drawing 20w.

You are saving 3p/day (21p/wk so i wasn't far out at 20p) compared to a 15/50 set on speed 1 or 10.5p against one set at speed 3. Even if it constantly drew 10w (which it won't) the saving would only be 4.5p/day

4.5 years (or 1.5) to get your money back on the extra 50 quid the pump cost.
As you say they can't be fitted alongside an abv so add in the cost of stripping that out or fitting a thermostatic controlled one and your customer will be dead before they recovered their costs.

The central heating system is shared and has it's own meter (single slot meter).
The reading includes boiler and controls. Continuous OTR is meant to set the flow temperature.

And it surely is not a 15/50.

Yes the pump does do long hours. In this case the saving is 3kW/day at 15p. The saving per month in this case (admittedly extreme) is somewhere around £13/month.
