Horstmann ECONOMY7 Immersion, Multi

Easy to use, works very well. Nice appearance. Dials easy to see.

Was able to replace with confidence as the installation guide is very clear

This worked well and was easy to install (mine replaced a Redring). However I have since replaced it with an electronic one as I did not like this one having to be on for 4.5 hours minimum each night - it is not possible to programme it for less, and it is also fiddly if your electricity supplier changes your e7 hours to different times when the clocks change. It is a good quality item, hence 4 stars, it’s just that the electronic digital version met my needs better.

Easy to install with good instructions booklet

It's a SECURE product and not Horstmann but it's identical in all respects. Plugged it in and worked which is perhaps the most important

I was a little sceptical on some of the time estimates to change a new for old timer but I was well please when I managed to change this out in under five minutes and working. Only minus for me is the minimum 4.5 hrs scheduled time for the water heating but if the element temp setting is set up properly then it should not remain on for the min 4.5 hrs, alternatively just use the boost button. Would recommend this item for the ease of fitting on its own as I only fitted the item today and time will tell if it stands the test of time and use.

This is advertised as Horstmann but is their own brand “Secure”. Obviously this is a breach of the Trade Descripions Act. That said, when you get over the shock of being duped, it’s absolutely identical to the failed Horstmann I bought it to replace and cheaper! Replacing it was easy. Set the clock. Yes, 4.5 hours is the min period but this isn't an issue as most tanks will heat up in 3 hours and then stay hot. The thermostat will stop any further electrical consumption. Just isolate the box, take out the front box screws, check no current is flowing into box with mains tester or multi-tester. Then pull off the connectors from the old unit, plug in the new ones, screw up the front screws and job done. It’s that easy. Description needs to change to Horstmann replacement rather than Horstmann and picture needs to be a Secure unit. One star lost for misrepresentation!
