Hi, I have just installed a 3kw elecro evo 900 heater. I have tried to get the set point to 14c but the top little dot will not stay on. The water temp is 11c so the heat on light should be constantly on right? But it just comes on for maybe 10 seconds every minute. Is this normal?

Thanks

James

try taking the temp setting up to 16c see if it stays on all the time....

they tend to have a couple of degree tolerance but shouldnt be as much as your saying.

hi i have one of these heaters but mine dont swing that much mine is more or less spot on is it digital or manual ? there support service is really good there number is 01438 749474and they give free tech advice

It's digital I timed it tonight and it heats for 37 seconds and goes to standby for 1 min 37 seconds. Is this normal working procedure or should it heat constantly until the set temperature is reached? It is slowly increasing the temp, only had it running for a day and it's gone up 1c.

hi JM mine turns on until it get it to the temp its supposed to be then switches of and dont come back on untill water drops in temp so i think something is not right i would ring them tomorrow if theres no one there to talk they take your number and they do yes they do ring you back

Hi Jm
I think the problem might be the flow you need to have a good flow through heater or the heater will switch off.

I have it running after my fish mate 45000 pressurised filter which is fed by a superfish 12000 at a head of 2 meters. I thought the flow would be more than enough?

yes min flow rate is a 1000ltrs that what it says on my booklet

JM350Z

Could having too much flow be a problem? It says max 7000. I think I will just call them tomorrow

It's not the flow because I just went outside and reduced the by closing the inline valve quite a bit and nothing changed, heats for 37 seconds then standby for nearly 2 minutes! So annoying
