Qmark Hydronic Heaters
I now have four have Qmark Hydronic heaters and love them. I am replacing all of my Cadet heaters with Qmark. They are quite, put out the necessary heat, and slim to the wall. Recommend them highly and also working with Air-N-Water was great! Great service by Mike M at Air-N-Water.

An Excellent Solution to My Small Trailer Heating Problem
While not producing a blazing inferno of heat, this product's silent, persistent output is well matched to my small travel trailer. Of course, it avoids a propane line and another open flame that would require careful venting. I particularly appreciate the fact that the entire assembly never gets so warm as to cause a burn if touched. The heat output is very close to the floor where the coldest air would otherwise collect and the warmed air can gently rise giving a pleasant warmth distribution. The compact size was an excellent fit in the "last" floor edge available. I use a Robertshaw 802 DPST line level thermostat which works well with the unit.

Safe, quiet and high quality space heater!
Our house is a 1950's Cape Cod style and the upstairs has doormer windows and high pitch ceilings, so we lose a lot of heat in the winter. Our heating system is only one zone (located on main level), so in order to heat the upstairs adequately, we have to turn the heat up and the main level feels like an oven, which is uncomfortable and expensive. We bought this model for our baby's room two years ago and have been very satisfied. It warms the room nicely, is super quiet and is very safe- stays warm to the touch, never gets hot. We recently bought a second unit for our bedroom and are equally happy. This item works great!

This product was more than expected
I ordered 2 of these heaters to put in a mechanical room and a foyer that stays cold all winter. this is for a vacation home, I am very please with the saftey features because I am not there all the time and I can leave this on the low setting and know that the rooms are warm when I am not there. they are very easy to install just need a couple of tools. One more thing is Air and Water dilivered this product fast, and they were very helpful on the phone when I was trying to decide what I needed.

I bought this baseboard heater for my 2 year old's bedroom. We needed a heater that was safer for children. I like that it has the automatic shut off if it overheats. Installation was really easy, to hard wire and its small size fits nicely in his tiny room. We live where it's wet and cold. This heater is keeping his room warm and dry at a low setting on the control dial. We would like to get two more, one for our family room and another in our bathroom. Also we ordered this product and it came exactly when they said it would. Very happy!

Use the heater in a small bathroom, it works great. Like the hydronics because I don't have to worry about heat coils starting a fire, or water splashing on the coils.

Two heaters and thermostats were purchased for installation in 2 small bath rooms in a hunt club. The club is heated by a wood stove so the heaters are for freeze protection during the "off" hunting season. The heaters are ideal as the thermostats do not have an off setting and the lowest setting is 40 degree F. The units are well construction, were easy to install, cannot be accidentally turned off and they do not pose any fire hazard. I expect them to provide many years of freeze protection.

Works great. Installed in bathroom. I can turn the heat down in the rest of the house over night. Keep the bathroom door closed during the night and when I get up in the morning the bathroom is toasty warm.

Improved heating vs standard baseboards. I am trying a couple of these. If they work better and more economically I will gradually replace all the electric baseboards in my house with this type.

We recently Ordered the HBB500 baseboard, and Honeywell 498 thermostat. We could not be happier with the performance of the items. This line of electric baseboard heater is by FAR the finest I have ever used.
