Stiebel Eltron DHM3 Mini Unvented Instantaneous Water Heater [Energy Class A]

Nice piece of kit - easy to install. Note, you are highly likely to need some adaptors - the ones in the box were not suitable. Reaches a reasonable and usable temperature.

Easy to fit and provide plenty of hot water.

We purchased this item in June 2014 and had it fitted by a registered plumber, initially it performed well then seemed to be unable to warm water, so we decided to change it for another heater which turned out to be worse and very short lived. We had this unit reinstalled and had the plumbing sorted, since then the heater has performed well day for the past 5 years, so I take back my previous feedback and would recommend.

Fantastic to have warm water for hand washing coming through in 1-2 seconds, instead of nearly a minute from the combi boiler.

Good unit, not as warm as I imagened but warm enough to wash hands. You do have to turn the water pressure down quite a lot to get the warm water. Easy to install. Good product

Absolute awful product, fitting this has resulted in me losing lots of money.Extremely poor flow rate and the temperature can not even be described as warm.Technical help line are as useless as the product also

Item supposed to be adequate for hand washing/kitchen sink. Water is only luke warm with through heater design flow. To attain decent temperature water has to be restricted to a mere trickle, difficult to maintain as heater element cuts out on too low a flow. Is not capable of producing water temp as stated . Rubbish!!

purchased & called out a plumber just to be told it doesnt work & is a waste of money.
