Dab pump

pjwhite99

Hi I’m thinking in getting heat hero and was informed that the

“DAB Evotron 8M Modulation Circulating Pump”
On there site is best to use with it.


Is it better to up grade ?

I have a dab pump it’s an a rated pump how can I tell what meter it is? It say min 6 max 44 on the side

And 40 70 130 on top

You probably have a Dab Evosta 4-7 (a 7Meter pump) which has 3 fixed speed settings and 6 PP (proportional pressure) settings, I would be surprised if the present pump isn't sufficient. I will try and dig out the Evotron data sheet later.

Thanks yes I have been looking on line and I believe my pump looks like a 4-7

Is it worth upgrading to that 8 meter? Is it much stronger?

There selling it on there site as a heat hero booster”

The heat hero is stil the same it’s only a pump that’s extra

I seen this pump is this the same as the one on there site?

The Evetron has 3 more settings CP (constant pressure), the heat hero may specifically need constant pressure settings so just contact them and ask them.

Yes, that's the one, I don't think you need a 8M pump personally but could be wrong.

What’s the difference in the 80/130 pump and the 80/180 pump? There 2 on the site is one better than the other

I think the 130 or 180 is the measurement between pump ends/flanges.

John.G

Don't see any difference in power outputs etc.

What function is the heat hero serving?, is there a number of pumps involved with two heat sources and is the system zoned with pumps or motorized valves?.

I have a range cooker and oil also

It’s zoned with motorized valves

I have 2 pumps one for the oil and the other is for the fire that’s the one I was told to upgrade with the heat hero

It’s runing 18 rads 2 story

I presume you are having problems with the solid fuel side so can you check the running mode and settings on your existing Dab pump, it should be IMO either on a fixed speed setting of 2 (5.5M) or 3 (6.8M) or (proportional pressure) PP6 which modulates between 2.5M & 4.8M, if its presently on a PP setting I would change over to fixed speed 2 or 3 as long as it doesn't cause pump back (pitching) into the header tank.

What is the make/model and present setting on your OIL boiler?

Did you ever get the pump as I have been informed to do the same and if so did it work
