Central heating pump

[Oviec92]

Hello everyone.

What's the most compatible replacement for the that pump?

Grundfos 15-50 or 60 will be ok?

Thanks

depends

It all depends on the application and the kind of boiler.

Tell us the boiler make and model and the number of rads and we can advise.

A 15-50 will probably suffice.

But energy regs say you should be using a smart pump as a replacement.

Euramo Gold was a 5M head, if memory serves. Tony is talking rubbish, a replacement doesn't not need to be a ERP circulation pump.

These are good;

My heating system is so old (still with hot water tank) need to be changed soon but at the moment it is Mexico slimline rs445 or cf440 (I'm not sure which one but maybe these are similar) with 5 radiators.

Hold on to your old boiler as long as you can matey. It may be OK for 30 years.
The circulation pump I posted up will do you just fine.
All the best Dickie.

Don't install Katsu! Their tools are bad enough copies. Technically not for the UK market and Katsu are unable to provide a certificate of conformity.

If you actually are a pro, please tell me you aren't installing these?

About 26 so far, we flash test them & not one has failed during field trials.

There's big moves in the trade to ban ERP circulation pumps, when we tell the chinless wonders in Brussels where to stick their Directives.

And you can stick your clipboard where the Sun don't shine!!

Just stating facts, no clipboard. You're the one liable if you fit imports without proper certification. The Katsu tools which are copies of Makita tools omit some of the suppression components so no way they can pass our EMC regs.

I agree with you that ERP circulation pumps are essentially a waste of time, almost certainly they fail sooner too. A CH pump is basically the worst place for some electronics so a plain induction motor based pump is always going to outlast them negating any energy savings.

Well the OP should just fit the Grundfos either way. Should be able to obtain for £60 to £80.

I only said that you "should" fit an energy saving pump. All the boiler manufacturers are using them now.

I have never seen one of those Chinese pumps and would certainly not want to use one unless it was the last pump in the world. I like to use good quality products for my customers.

Not sure what Puller sees as the advantage of using them. Unless its for social housing and just to use the worst and cheapest. Look where that got Kensington and Chelsea Council!

Are you seriously comparing me to that??!!! Of course I'll report this as a disgraceful insult & abuse Tony. It's ridicules, the worst a faulty circulation pump can do is trip a breaker or leak, hardly a comparison FFS!!

Exactly, it's of no benefit to him as an installer other than replacing it in three years. False economy when the Grundfos typically lasts 15-20 years.
