DeLonghi TCH6590ER, Extremely stupid control..

Extremely stupid control logic

This heater works reasonably well, it’s not too noisy on the LOW setting, but it’s electronic control is designed extremely bad. First of all it has three operational modes: LOW, HIGH and AUTO. Low uses half of its heating power and runs the fan on a slower and quieter speed. High - uses full power and is the noisiest. Thermostat setting/operation is not available nether under low nor under high mode.
On Auto mode you can set the desired temperature and the heater will do a reasonably good job of maintaining the set temperature, but - when it’s on Auto mode the heater runs on it’s full power and becomes noisy.
There is no way to make use of the thermostat with the low heating power.
I think that most people would actually want to use Auto mode with the low power, especially if they use the heater in a bedroom, but some genius at DeLonghi decided to save a few cents by not providing this option.
The heater also ‘forgets’ your last Auto temperature setting after you switch it off and defaults to 75, so every time you switch it on again you have to adjust temperature - pretty annoying IMO. In spite of the fact that I got it pretty cheap (under 40), it’s going back.

Does the job for small rooms
Picked this up a few weeks ago when it first showed up because my old space heater had a VERY noisy fan, and no thermostat for auto-shutoff.

It saw its first use over the last few days when I intentionally kept the thermostat for the home’s heating a bit low, and turned this on in the specific room that was occupied. Not bad - warms up quickly, oscillates smoothly, accurate sensor (double checked against Oregon Sci. homewide system) and changes temperature in a medium-sized room reasonably quickly. Also very quick to turn off when it reaches the right temperature (in its proximity at least, doesn’t guarantee it has heated the entire room to the set temp, of course - compensate by setting it another degree or two higher). By forcing it to make up for around a 2-3 degree delta below my comfort zone (homewide setting kept 2-3 lower than I’d like), this stayed on for barely 20-25% of the time and kept me comfortable in a 12×18ish room with medium-high (10 foot) ceilings. Fan noise somewhat noticeable … since this room was my (above ground) basement level and serves as my home theatre/office … but it isn’t too loud for ME to fall asleep. YMMV!

For the price I got it (under 40), not bad! At the current price, it’s a wash, and noise sensitive folks may want to consider the oil-filled radiator style heaters instead!

Gets the job done, but is a little noisey and lacks some functionality
I purchased this heater because our house has wall heaters out in the hallway and in the living room, but none in the bedroom. So on cold nights we’d have to leave the bedroom door open and use the hallway heater to heat the hallway, and in turn the rest of the house - not very economical.

The good:

** Remote control is handy
** Puts out plenty of heat to heat a medium sized bedroom
** Noise level is okay on the low heat setting
** Lighted lcd makes reading the settings easy at night, but turns off after a few seconds so it doesn’t light up the room

The bad:

** As others have reviewed, the thermostat feature is great but the heater only operates in high heat mode when you have the thermostat feature enabled; in which the fan speed is high, and if you are a light sleeper like me it’s enough to wake you (my wife slept right through it).

** It has no memory, so when you power it off, and back on, it forgets what mode it was in and what temperature it was set on; not a big deal though because you can turn it on and set the mode/temp in a snap w/ the remote.

** When in thermostat mode the temperature seems to vary a bit. The manual claims it will heat to 2 degrees above your setting, then turn off until it gets to 2 degrees below your setting. So basically +/- 2 degrees, but it feels like more than that.

Bottom line: If you don’t care about a little noise and temperature variance, it has lots of other great features and gets the job done. However, I did end up returning this and got the silent Honeywell wall heater which I’m very happy with, mainly due to the silence.
